ObjectivesIt has been well established that cooking method, marbling level, and cooked internal temperature endpoint affect beef flavor, the most important driver of consumer acceptance. However, beef cuts respond differently to cooking method and cooked internal temperature endpoint based on their inherent chemical characteristics.Materials and MethodsTreatments were: beef cuts (inside round, bottom round, and eye of round); USDA beef quality grade (upper two-thirds Choice and Select); cooking methods (pan grill, stir fry, stew no marinade, stew marinade, and roast); and internal cook temperature endpoints (58, 70, and 80°C). The pan grill cook method included 0.25 and 0.75 in samples from each muscle type. The stir fry cook method treatment was limited to 0.25 in cuts, which were cut into 1.00 in strips prior to cooking. The marinated and non-marinated stew cook method treatments included 0.25 and 0.75 in samples from each muscle. These samples were then cut into 0.25 × 1.00 × 1.00 in and 0.75 × 1.00 × 1.00 in samples prior to cooking. Stew marinated samples were marinated with 118 mL water, 90 mL lemon juice, 30 mL canola oil, 5 mL salt, and 2.5 mL pepper. Two lb roasts were cut from bottom round and eye of round subprimals and inside round subprimals were cut into 2.00 in roasts prior to cooking. An expert descriptive beef flavor and texture attribute panel evaluated each sample using 16-point scales for flavor and texture attributes. Warner-Bratzler shear force (WBSF) were determined. The trained panel results and WBSF values were analyzed using Proc Means and Proc GLMMIX procedures of SAS (version 9.4, SAS Institute, Cary, NC) with a predetermined α of 5%.ResultsQuality grade impacted flavor for the inside round (P < 0.05). USDA quality grade had minimal effect on tenderness as expected, as beef round cuts are highly active muscles in the animal and contain considerable amounts of connective tissue. Cooking method and internal cook temperature endpoint, or cooking time for the stewing cooking treatment, impacted beef flavor to a greater extent (P < 0.05). When pan fried, thicker cuts resulted in more positive flavor attributes. For cuts that were roasted, cooking to higher internal temperatures resulted in higher levels of beef identity, roasted, and umami flavors and less serumy/bloody flavors, as well as decreased tenderness (P < 0.0001), especially in inside round roasts. Marinated round cuts were more tender than their non-marinated counterparts (P < 0.0001). Cuts that were thinner and had longer cooking times were more tender but had more off-flavor attributes (P < 0.05).ConclusionCut thickness, cooking method, length of cooking or internal cook temperature endpoint, and presence of marinade affected flavor and texture of bottom round, eye of round, and inside round cuts. This data will be useful in providing consumer and food service personnel recommendation on how to maximize the flavor and texture of beef round cuts.

ObjectivesCooking meat using a clamshell grill has become common in university research settings due to speed, relative low cost, and acceptable repeatability. However, other cooking methods such as charbroiling and salamander grills have also become a popular method in the hotel and restaurant industry. The objective of this experiment was to evaluate the effect of different dry heat cooking methods on beef palatability across a range of USDA quality grades.Materials and MethodsA consumer panel (n = 288) was conducted at Texas Tech University. Strip loin steaks from four different USDA quality grades (Prime, upper 2/3 Choice, lower 1/3 Choice, and Select) were cooked using one of four cooking methods: electric clamshell grill (CLAM), flat top gas grill (FLAT), Charbroiler gas grill (CHAR), or Salamander gas broiler (SAL). After cooking to medium degree of doneness (70–72°C), steaks were cut into cubes (1.3-cm × 1.3-cm × steak thickness), and two cubes were served immediately to 6 predetermined consumers from each steak. Each consumer evaluated 8 samples, representing half of the 16 possible quality grades × cooking method treatment combinations. Consumers scored juiciness, tenderness, flavor liking, and overall liking using electronic ballots with the zero-point anchors labeled as extremely dry, extremely tough, dislike flavor extremely, and dislike overall extremely and the 100-point anchors labeled as extremely juicy, extremely tender, like flavor extremely, and like overall extremely. Also, consumers rated each sample as either acceptable or unacceptable for each palatability trait.ResultsThere were no interactions between the cooking method and quality grade for any of the palatability traits (P > 0.05). Steaks cooked on CHAR had greater (P < 0.05) flavor and overall liking scores, as well as a greater percentage of samples (P < 0.05) that were considered acceptable overall compared to the other cooking methods. Steaks cooked on FLAT were scored lower (P < 0.05) for tenderness and juiciness compared with all other cooking methods. Steaks cooked on CLAM, SAL, and CHAR were scored similarly for tenderness and juiciness (P > 0.05). Steaks cooked on FLAT were scored lower (P > 0.05) than CHAR and SAL for overall liking. Steaks cooked on CLAM had lower (P < 0.05) flavor liking scores than CHAR and SAL. Prime samples had greater scores (P < 0.05) than Low Choice and Select, which were similar (P > 0.05), for tenderness, juiciness, flavor liking, and overall liking, but Prime did not differ from Top Choice (P > 0.05) for any palatability traits.ConclusionThese results indicate cooking method had a significant impact on consumer palatability ratings, and those results were consistent across a range of quality grades. Even though these cooking methods are all classified as dry heat cookery methods, consumers in this study were able to detect differences in tenderness, juiciness, flavor liking, and overall liking. This may be due to increased cooking times or differing types of heat transfer possessed by the various cooking methods. These data suggest cooking steaks by CHAR resulted in the most desirable eating experience, and cooking steaks on FLAT and CLAM were less desirable. However, the low eating satisfaction of FLAT can be linked to low tenderness and juiciness, whereas CLAM liked less due to low flavor liking.

The wide range of products, processing conditions, processing equipment, methods for assessing sensory and nutritional quality calls for a more holistic approach to when choosing the right food technology. The sensory quality of sous vide foods was the main factor which brought it to international attention. Today this new food service technology used by catering companies, restaurants and, increasingly, home cooks. Sous vide differs from traditional cooking methods in two fundamental ways: the raw food is vacuum-sealed in heat-stable, food-grade plastic pouches and the food is cooked using precisely-controlled heating. Sous vide cooking method it provides a high nutritional value, improved texture, and tenderness, maintains the juiciness as a result of low-temperature cooking, reduces lipid oxidation for an extended shelf life and prevents loss of volatile flavors and moisture during cooking because of vacuum packaging.This article summary reviews the basic techniques, changes in quality indicators of meat, fish and vegetable foods in regard to food safety, and science of sous vide cooking.

ObjectivesThe objective of this study was to evaluate instrumental measures of tenderness and juiciness of beef strip loin steaks representing four different USDA quality grades cooked using four dry heat cooking methods.Materials and MethodsStrip loins (n = 12/quality grade) were collected from four USDA quality grades [Prime, Top (upper 2/3) Choice, Low (lower 1/3) Choice, and Select]. At 21 d postmortem, strip loins were cut into 2.5 cm thick steaks and stored at –20°C until analysis. The most anterior steak was used for compositional analysis and every three adjacent steaks were grouped and assigned randomly to one of four different dry heat cooking methods [electric clamshell grill (CLAM), flat-top gas grill (FLAT), charbroiler gas grill (CHAR), and salamander gas broiler (SAL)]. Objective measures for raw samples included proximate composition and for cooked samples included cooking loss, pressed juiciness (PJP), and slice shear force (SSF) after the sample was cooked to a medium degree of doneness (70–72°C). In addition, consumers assessed attributes for each sample on an electronic ballot with a 100-point continuous line scale for juiciness, tenderness, flavor liking, and overall liking. Proximate data were analyzed using the GLIMMIX procedure of SAS with quality grade as the fixed effect. All other data were analyzed as split-plot design with quality grade as a whole plot factor, the strip loin as the whole plot unit, and cooking method as a subplot factor.ResultsUSDA Quality grade influenced fat, moisture, and protein percentage (P < 0.01). As expected, there was a fat percentage difference (P < 0.05) between each grade with a decline from Prime to Select samples. Therefore, Select had a greater (P < 0.05) moisture percentage than any other quality grade, and an inverse relationship was observed as there was an increase in moisture between each grade from Select to Prime (P < 0.05). Select and Low Choice had greater (P < 0.05) protein percentage than Top Choice or Prime, which were similar (P > 0.05). As expected, an inverse relationship between increased marbling levels and decreased SSF scores were also observed resulting in a negative correlation between fat and objective tenderness (r = –0.15; P < 0.05). In addition, fat was positively associated with consumer palatability scores (r ≥ 0.21; P < 0.01). Cooking method influenced (P < 0.01) cooking loss, but did not impact SSF or PJP (P ≥ 0.19). CLAM had lower (P < 0.05) cooking loss than FLAT, SAL, and CHAR, which did not differ from each other (P > 0.05). The lower cooking loss of CLAM could be related to the shorter cooking times compared to the other methods. Pressed juiciness percentage was not influenced by quality grade, cooking method, or their interaction (P ≥ 0.19) and was not related to any objective or subjective measures of palatability (P > 0.05). Slice shear force was not influenced by quality grade, cooking method, or their interaction (P ≥ 0.15); however, SSF was related (r ≤ 0.18; P < 0.05) to tenderness, juiciness, flavor and overall liking.ConclusionIn the current study, quality grade influenced the composition of raw samples, yet, quality grade coupled with different dry heat cooking methods did not influence objective measures of tenderness or juiciness.

Vegetable consumption is associated with increased health benefits, and vegetables are consumed both in cooked form and raw form in salads. All cooking techniques cause changes in a vegetable’s the nutrient content. Consumers are increasingly health-conscious and have less time to prepare meals, and they do not know which cooking times and cooking methods are best suited to preserve the nutrients. This study aimed to determine the best method of cooking vegetables to maintain minerals (potassium and sodium) and carotenoids. The studied vegetables were broccoli (Brassica oleracea, var. Italica), carrots (Daucus carota), and zucchini (Cucurbita moschata). The cooking methods were: boiling, steaming, combined oven, microwave steaming, and microwave cooking. Samples of organic and conventionally grown vegetables were prepared in triplicate. Samples were analyzed to determine the availability of target minerals and carotenoids in the raw food and in each recommended cooking situation according to technical standards. Only the carrot showed a higher concentration in organic cultivation for carotenoids in raw vegetables, with both zucchini and broccoli having higher concentrations when grown by conventional cultivation. The zucchini from organic cultivation presented a reduction of potassium and sodium, almost consistently, in all cooking techniques. Regarding the conventionally cultivated zucchini, potassium remained stable in boiling. Broccoli from organic and conventional cultivation showed similar potassium levels for boiling and traditional steam cooking. Organic carrots showed easier sodium extraction compared with conventional cultivation. Heat treatment, in general, improves the accessibility of carotenoids.

ObjectivesConsumer research has consistently shown that consumers over-cook pork creating a subpar eating experience. In 2011, the USDA/FSIS changed the internal doneness temperature from 71.1 to 62.8°C. However, how tenderness and water-holding capacity is affected in pork chops and roasts differing in thickness and color score cooked to 62.8°C is unknown. Understanding these relationships from chops and roasts cooked to 62.8°C is crucial to the pork industry.Materials and MethodsBoneless and bone-in pork loins were purchased commercially on 3 selection trips to represent the National Pork Board subjective color scores of 2 and 4. The tenderloin was removed from the bone-in loins and randomly assigned to treatments. The sirloin and blade ends were removed, and bone-in ribeye chops were cut to either 1.3, 1.9 or 2.5 cm thick. Twelve chops were cut from each loin with a portion of the rib bone present in each chop. The blade end of the boneless loins was removed, and blade chops were cut to either 1.3, 1.9 or 2.5 cm thick. Three blade ends within color score were used to obtain 12 chops. The boneless center-cut chops were cut to either 1.3, 1.9 or 2.5 cm. Each boneless loin was cut into 12 chops. Boneless loin roasts (0.9 and 1.8 kg roasts) were cut from color score 4 boneless loins. Whole boneless center-cut loin roasts were cut into 2.7 kg roasts from the color score 2 loins. Prior to cooking, drip loss, pH and raw color were determined. Chops were then cooked to 62.8°C either by baking, grilling, pan frying, or pan-sautéing. Roasts were cooked to 62.8°C either by baking or grilling. Internal temperature was monitored by inserting an iron constantan thermocouple into the geometric center of the chop or roast. Cook yield, cook time, tenderness assessed by Warner-Bratzler shear force, and cooked internal color were determined. Each of the 24 treatments for each type of chop (2 colors × 3 thicknesses × 4 cooking methods) and the 8 roast treatments (4 weights × 2 cooking methods) were replicated 20 times.ResultsCooking method and chop thickness affected cook yield and cook time. Baked chops had the longest cooking times and sautéed chops had the highest cook yields (P < 0.05). Grilled chops had the highest (P < 0.05) cook loss. The color score 4 blade and boneless chops were more tender than the color score 2 chops (P < 0.05). However, for bone-in chops, the inverse was reported (P < 0.05). Thickness had minimal effect on tenderness for the boneless chops (P < 0.05). Although bone-in and boneless, baked chops had the longest cooking times, they were the most (P < 0.05) tender. Baked whole boneless roasts had higher cook yield and longer cook times from grilled whole boneless roasts (P < 0.05). For boneless loin roasts (0.9 kg), baked roasts had higher cook yields, longer cook times, were tougher, and had a redder internal cook color than boneless loin roasts that were grilled (P < 0.05). Heavier boneless loin roasts had lower cook yield, longer cook times, and were tougher compared to lighter weight boneless loin roasts (P < 0.05). Baked tenderloins had higher cook yield, longer cook times and were redder in internal color than grilled tenderloin roasts (P < 0.05).ConclusionOverall, this study revealed that color, cooking method, and thickness impacted drip loss, cook yield, cook time, cooked color, and tenderness of blade, boneless, and bone-in chops, tenderloins, and roasts.

CHEMICAL COMPOSITION AND ORGANOLEPTIC CHARACTERISTICS OF PROCESSING BAT (Pteropus alecto) FRESH MEAT. Study was done to evaluate chemical composition and preference degree of the consumers on the processing bat meat compared with beef, chicken and cakalang fish using steam cooking method, flavor cooking and spicy cooking method. Chemical composition was analyzed by proximate analysis using procedures of the Association of Official Analytical Chemists. The organoleptic test was done by hedonic test. Data of the hedonic test were analyzed using Kruskal-Wallis method. To evaluate data distribution of the panelist respons on the sample test, the data were using plot graphic box. The hedonic scales were using 1 to 7. The variables used were including color, taste, flavor, tenderness and general acceptance. Results of proximate analyses of bat meat based on fresh meat indicated that water content was 67.21 percents and protein was 20.48 percents. Based on dry matter, the protein contents of bat meat, pork, chicken, and cakalang fish were 48.97 percents, 69.08 percents, 67.14 percents, and 69.41 percents, respectively. The water contents were 5.76 percents, 9.92 percents, 8.27 percents, and 9.90 percents, repsectively; the calcium (Ca) contents were also 10.62 percents, 1.09 percents, 1.36 percents, 1.38 percents, respectively; while Phosphor (P) contents were 1.46 percents, 0.69 percents, 0.66 percents, and 0.72 percents, respectively. Variance analysis for organoleptic test showed that meat type with different processing affected significantly on taste, color, flavor, tenderness and general preference of bat meat, beef meat, chicken meat and cakalang fish by steam cooking, chicken flavor, and spicy cooking methods. Conclusion, bat meat contained protein relatively lower than that in pork meat, chicken meat, and cakalang fish, but mineral contents were relative higher. Results of organoleptic test showed that preference degree of processing meat were higher on using spicy flavor. The specific test on taste, color, flavor, tenderness and general responsed showed relatively the same responses by the panelists.   Key word: Chemical composition, organoleptic test, processing bat meat

This study investigates the effects of three cooking methods (boiling, steaming and microwaving) on the nutritional and physical properties of cauliflowers, carrots and sweet potatoes; e-senses were applied to interpret the sensory characteristics according to physico-chemical aspects. The nutritional quality was evaluated by determining the concentrations of key components and the antioxidant activity; e-sense data, combined with texture parameters, were processed by a principal component analysis. The cooking method and time significantly influenced the quality of the three products. Boiling, which detrimentally affected ascorbic acid, total phenolic concentration and antioxidant activity, enhanced carotene accessibility. Steaming produced losses in ascorbic acid, increasing total phenolics and carotenoids. Microwaving resulted in minor changes in ascorbic acid concentrations, preserved carotenoids and increased total phenolics. The nutritional quality was better preserved or enhanced using shorter cooking times. The elaboration of the data collected by the e-senses showed a clear evolution according to the cooking method and time. The results helped to determine the cooking method that best preserves the nutritional properties of the vegetables, highlighting the applicability of rapid instrumental methods to interpret the evolution of sensory characteristics.

The aim of this study was to examine the cross-sectional association between fish and shellfish intake and impaired glucose metabolism with consideration for cooking methods in a Japanese working population. Participants were 1774 workers aged 18–69 years. Dietary intake was assessed using a validated self-administered diet history questionnaire. Participants were asked about their most frequently used cooking method for fish, and the method was classified as either “raw and stewing” or “broiling, deep-frying, and stir-frying”. Impaired glucose metabolism was defined by a history of diabetes, current use of anti-diabetic drugs, fasting blood glucose ≥110 mg/dl, or HbA1c ≥6.0%. Logistic regression analysis was used to estimate the odds ratios of impaired glucose metabolism for fish intake by cooking method. Fish intake was not associated with impaired glucose metabolism in either group. When the outcome was defined as diabetes, the odds of diabetes increased with fish intake among participants who most frequently used broiling, deep-frying, or stir-frying methods, albeit they were not statistically significant; the multivariable-adjusted odds ratio for the highest versus the lowest tertiles of fish intake was 1.95 (95%CI, 0.71–5.41). Cooking methods for fish may not modify the association between fish intake and impaired glucose metabolism among Japanese populations.

There are many ways to prepare potatoes that each provide a unique set of sensory properties. However, when conducting a descriptive sensory study, it is important to utilize a cooking method that will highlight, and not distract from, the sensory differences among potato samples due to factors such as variety or growing conditions. This study aimed to determine which of five cooking methods results in the best differentiation among potato varieties to recommend a single method for use in future descriptive sensory studies. Five different potato varieties were each prepared using boiling, mashing, baking, frying, and air frying methods. The samples were provided to six highly trained descriptive panelists and evaluated by consensus using a modified high identity traits (HITs) method. Panelists evaluated the aroma, flavor, and texture to develop a list of up to five total HITs per sample. Additionally, panelists scored each sample for degree of difference (DOD) from the control. Based on the HITs profiles and DOD scores, mashing, baking, and air frying methods were all effective in differentiating the samples. Frying and boiling methods introduced too much variation and are not recommended for sample differentiation. Ultimately, the method chosen for future research would depend on the study objectives.

Force Variation

The effects of cooking method on beef longissimus thoracis et lumborum (LTL) tenderness and tenderness variation were investigated. Steaks from three tenderness categories (tender: shear force <68.7 N; moderate: 68.7 N < shear force <103 N; tough: shear force >103 N; 8 loins per category) from commercial loins werecooked to an internal temperature of 72 °C using a single-sided grill, a double-sided grill, or a water bath. Shear force was not affected by cooking method or core location. Regressing within-animal shear force SD versus within-animal shear force gave a significant positive correlation (R = 0.76; P < 0.001), indicating that shear force variation increases as toughness increases. Results indicate that more shear force measurements need to be taken for tough versus tender steaks if an equal repeatability of shear prediction is to be made, regardless of cooking method.
