Abstract The effects of beef genetics and finishing system on color and sensory attributes of longissimus dorsi steaks were evaluated. Steaks were from Red Angus (RA, n = 30) and RA x Akaushi (AK, n = 30) fed with a mixed-species pasture forage (GRASS) or a total mixed feedlot ration (GRAIN). Animals were slaughtered at 18 (GRAIN) and 26 (GRASS) mo. Rib sections (11th and 13th) were collected 48 h postmortem from the left side of each carcass, cut into two 2.54 cm-thick steaks, vacuum packaged, and aged 14 d. One steak was frozen until water holding capacity and Warner Bratzler shear force (WBSF) analysis. The other fresh steak was evaluated for instrumental color and cooked for consumer panelists (n = 105) to evaluate flavor, texture, juiciness, and overall acceptability using a 9-point hedonic scale (1 = dislike extremely and 9 = like extremely). There was no difference between beef genetics. GRASS had higher chroma (more color saturation) and a* values (redder) compared to GRAIN treatment. There was genetics x diet interaction for hue angle and L* values, where RA had greater hue angle than AK in GRAIN (P = 0.01) and AK had greater L* (lighter, P < 0.01) than RA in GRASS. The GRASS-finishing reduced beef steaks thawing (-20 %) and cooking (-12.8 %) loss compared to GRAIN-finishing (P < 0.05). There were no differences (P > 0.05) in WBSF between finishing systems. Steaks from GRAIN received the greatest ratings (P < 0.01) for flavor, texture, juiciness, and overall acceptability compared to GRASS. Results indicate that the color attributes were influenced by finishing system. Furthermore, beef finishing system had a marked impact on steaks’ sensory attributes and consumer acceptability. The favorable results for texture and juiciness in GRAIN, which likely impacted overall acceptability, may be related to high marbling.

Demographic Effects

Abstract Beef genotypes and diets can improve the eating quality and consistency of beef. A 2-yr study was conducted to evaluate the effects of beef genotypes and diet on consumer acceptability of beef. Steaks were from Red Angus (RA) and RA x Akaushi (AK) crossbreed, fed one of two finishing systems: grazing (GRASS) and feedlot (GRAIN). Consumers (n = 105 in each year) evaluated cooked steaks for flavor, tenderness, juiciness, and overall acceptability using a 9-point hedonic scale. Demographical information was collected and used as covariates in the statistical model. There was no difference in sensory attributes (P > 0.05) between the genotypes, except that steaks from AK tended to be juicier than RA (P = 0.06). Sensory attributes were scored better in GRAIN than GRASS beef (P < 0.01) for all variables. There was a genotype by system interaction for flavor (P = 0.02), where beef from RA had a lower flavor rating in GRASS than in GRAIN, and no difference was observed for AK. Demographic effects showed that gender and beef consumption location had significant effects on flavor. Flavor scores were higher for females than males (6.1 vs 5.7, P = 0.02), and higher from consumers who eat beef in restaurants than consumers who do not eat beef in restaurants (6.6 vs 5.3, P < 0.01). Juiciness scores were impacted by the frequency of beef consumption. Panelists who eat beef once every 2–3 weeks rated the steaks juicier than those who eat beef once every 2–3 months (6.5 vs 4.3, P = 0.04), and consumers who eat grass-fed beef twice a year rated the steaks worse than those who eat it less than once a year (P = 0.02). Our results suggest that the beef finishing system had a marked impact on consumer acceptability, and AK might produce meat juicier than RA. Some demographic factors may influence consumer perceptions of beef.

Abstract A 2-yr study was conducted to evaluate the effects of beef genotypes and feeding systems on performance, carcass traits, meat quality, and sensory attributes. A 2×2 factorial experiment was used to randomly allocate 60 steers in year 1 (YR1) and 44 steers in year 2 (YR2). The two beef genotypes evaluated were Red Angus (RA), and RA x Akaushi (AK) crossbreed. The steers were allotted to two finishing feeding systems: grazing, a multi-species forage mixture (GRASS) and feedlot finishing, conventional total mixed ration (GRAIN). All steers were slaughtered on the same day, at 26 and 18 mo of age (GRASS and GRAIN, respectively), and carcass data were collected 48 h postmortem. Growth and slaughter characteristics were significantly impacted by the finishing system (P < 0.01), with the best results presented by GRAIN. Beef genotype affected dressing percent (P < 0.01), ribeye area (P = 0.04), and marbling score (P = 0.01). The AK steers had a tendency (P = 0.09) for lower total gain; however, carcass quality scores were greater compared to RA. There was a genotype by system interaction for USDA yield grade (P < 0.01), where it was lower in GRASS compared to GRAIN in both genotypes, and no difference was observed between the two genotypes for any GRASS or GRAIN systems. There was no difference in meat quality or sensory attributes (P > 0.10) between the two genotypes, except that steaks from AK tended to be juicier than RA (P = 0.06). Thawing loss and color variables were impacted by the finishing system (P < 0.01). L* (lightness) and hue angle presented greater values while a* (redness), b* (yellowness), and chroma presented lower values in GRAIN compared to GRASS. Sensory attributes were scored better in GRAIN than GRASS beef (P < 0.01). There was a genotype by system interaction for flavor (P = 0.02), where beef from RA had a lower flavor rating in GRASS than in GRAIN, and no difference was observed for AK. Within each system, no difference was observed for flavor between RA and AK. Beef from steers in GRASS had greater (P < 0.01) WBSF than those from GRAIN. These results indicate that steers from GRAIN had superior performance and carcass merit and that AK enhanced these traits to a greater degree compared to RA. Furthermore, the beef finishing system had a marked impact on the steaks’ sensory attributes and consumer acceptability. The favorable results for texture and juiciness in GRAIN, which likely impacted overall acceptability, may be related to high marbling.

Twenty Yankasa rams aged between 10 and 12 months with average weight of 12.15kg were used to evaluate the effect of different levels of biscuit waste and Leucaena leucocephala meal inclusion in diets on the quality of their meat samples. The rams were randomly assigned to five treatment diets of 0%, 25%, 50%, 75% an d100% of combined biscuit waste and Leucaena leucocephala in replacement for combined maize and wheat offals or B0, B1, B2, B3 and B4 diets with four rams per diet for 91 days. Data were collected on physical, chemical and sensory variables of meat samples. The results showed that there were significant (P<0.05) differences in the cooking loss, water holding capacity, crude protein and overall acceptability of meat samples from the rams. All the parameters measured were better in meat samples from rams fed treatment diets B1 (25%) and B2 (50%) inclusion of biscuit waste and Leucaena leucocephala meal. The results revealed that feeding biscuit waste to Yankasa rams can improve the quality as well as the consumer acceptability of Yankasa rams meat (mutton).

Grape juices are blended in order to balance the organoleptic characteristics of juice, as well as to reduce off-season costs. The aim of this study was to evaluate the acceptance of consumers, through sensory analysis, of ‘Bordô’, ‘Niagara Rosada’, ‘BRS Nubia’ and ‘Isabel’ grape juices and their blends. The experiment was conducted during two periods. In the first, the grape juices analyzed were: ‘Niagara Rosada’ 100%, ‘Bordô’ 100%, ‘Isabel’ 100%, ‘Isabel’ 90% + ‘Bordô’ 10% and ‘Isabel’ 80% + ‘Bordô’ 20%. In the second, the following juices were evaluated: ‘Bordô’ 100%, ‘Niagara Rosada’ 100%, ‘Bordô’ 75% + ‘Niagara Rosada’ 25%, ‘Bordô’ 50% + ‘Niagara Rosada’ 50%, ‘Bordô’ 25% + ‘Niagara Rosada’ 75% and ‘BRS Nubia’ 100%. The juices were obtained by the ‘Welch’ process by steam entrainment. For the sensory evaluation, six tasters evaluated the following attributes in each period: color, aroma, flavor, body and overall acceptability, using a 7-point hedonic scale. The ‘Niagara Rosada’ juice 100% presents low acceptance, while the ‘Bordô’ and ‘Niagara Rosada’ juices up to 1:1 (v:v) show high acceptance, as well as ‘Bordô’ and ‘Isabel’ blends, confirming the importance of ‘Bordô’ juice for grape juice blends. The ‘Nubia’ juice 100% may be an alternative for grape juice blends due to its intense color.

The purpose of this study was to investigate the effect of papaya leaves crude extract on the physicochemical properties of marinated chicken meat. Papaya leaves was extracted with sodium acetate (CH3COONa) buffer (pH 7.2) at room temperature. Protein concentration and activity of enzyme in the crude extract were determined by using UV-Spectrophotometer. The crude extract was mixed with marinated ingredients and then coated onto chicken meat which was subsequently kept for overnight in refrigerator at chill temperature. Protein concentration of the enzyme was identified as 166.36 μg/μl and enzyme activity was 1.28 CDU/ml. Results also showed that lightness (L*), cooking loss and shrinkage of the marinated chicken were higher than control. Redness (a*), yellowness (b*), protein content, water-holding capacity, shear force, and texture profile analysis were lower than control. Microstructure analysis showed that the chicken meat muscle was destructed in the presence of papaya crude extract. Sensory acceptability evaluation of marinated chicken which was carried out by using 9 point hedonic scale suggested that chicken meat treated with papaya crude extract gave significant effect on texture, juiciness, flavour and overall acceptability compared to commercial bromelain. Additionally, the use of papaya crude extract gave a significant effect on the physicochemical properties of marinated chicken.

The investigation was conducted in the Molecular Horticulture Laboratory of Agrotechnology Discipline, Khulna University to develop processed products from jackfruit through their sensory evaluation in order to see their suitability and consumer acceptability. Using variation in sugar contents five preparations of raw jackfruit green pickle, four preparations of rind jelly and bulb jelly, and three preparations of jam, squash and sweet pickles were successfully prepared. Results from sensory evaluation using a seven point hedonic scale to rate for color, taste, flavor, texture and overall acceptability by untrained panelists indicated preparation No. 3 of green pickle, preparation No. 3 and 4 of rind jelly, preparation No. 2 of bulb jelly, jam, squash and sweet pickle scored highest among all the preparations. The storage of these products in normal room temperature showed that produced pickles remain unchanged even after 12 months of storage. But the quality of jam, jelly and squash started to deteriorate after 7 months of storage due to the absence of preservatives. Based on results, it can be concluded that commercial production of the products by using different parts of jackfruit can be taken up and promoted as a small scale income generating activity.J.

ABSTRACT New microbial performance standards for chicken parts necessitate postchill antimicrobial interventions to make poultry parts safer for consumers. This research was conducted to determine the effectiveness of antimicrobials (0.003% chlorine; 0.07% acidified sodium chlorite [ASC], 0.07 or 0.1% peracetic acid [PAA], and 0.35 or 0.60% cetylpyridinium chloride [CPC]) when used in a postchill decontamination tank to reduce Salmonella and Campylobacter on broiler chicken parts (including breasts, thighs, wings, and drumsticks) and to determine the sensory attributes of the treated samples. Samples (n = 90, 9 treatments × 5 samples × 2 replications) were inoculated with Salmonella Typhimurium (108 CFU/mL) and Campylobacter jejuni (108 CFU/mL). After a 30-min attachment time, chicken parts were rinsed with various antimicrobials in a decontamination tank for 23 s. Salmonella and Campylobacter reduction was determined by sampling parts after the treatments were applied. Sensory evaluation of skin-on (drumettes) and skin-off (breast meat) parts were conducted by untrained panelists by using an 8-point hedonic scale. CPC (0.35 or 0.60%), provided a reduction of 2.5 or 3.5 log CFU/mL on Salmonella and a reduction of 4 or 5 log CFU/mL on Campylobacter, respectively. Both concentrations of PAA (0.07 or 0.1%) provided a 1.5-log reduction on Salmonella and Campylobacter. Chlorine at 0.003% and ASC at 0.07% were the least effective antimicrobials, providing &lt;1-log reduction for both pathogens, which did not differ from the reduction provided by a water rinse alone. Sensory attributes were unaffected in drumettes, and skinless breast fillets received the most acceptable scores (P ≤ 0.05) for texture, juiciness, and overall acceptability when treated with 0.07% PAA and 0.35% CPC. Results from this study indicated that using PAA and CPC in a postchill decontamination tank are effective treatments for reducing Salmonella and Campylobacter on chicken parts, with minimal effects on product quality.

Eucheuma Cottonii

The objective of this work was to study the effect of seaweed (Eucheuma cottonii) our addition on physicochemical and sensory characteristics of an Indonesian-style beef meatball. Seaweed flour (SF) was added to meatball batter at 0% (CON), 2.5% (SF2.5), 5.0% (SF5) and 7.5% (SF7.5) in weight/meat weight (w/w) basis. Proximate composition (moisture, crude protein, crude fat, crude fiber and ash content), pH, cooking loss, hardness, water-holding capacity, instrumental color and sensory properties (color, texture, aroma, taste and overall acceptability) of the boiled meatballs were evaluated. The effect of seaweed our addition was very significant (P<0.01) on moisture, crude fat, crude fiber, ash, cooking loss, hardness, water holding capacity, lightness (L*), yellowness (b*) and all sensory properties, and was significant (P<0.05) on crude protein, pH and the redness (a*) of a boiled Indonesian-style beef meatball. The addition of seaweed flour at more than 2.5% resulted in darker meatballs, with less protein and fat, and a stronger seaweed aroma. The results suggest that seaweed flour could be added at 2.5% (w/w) to produce an Indonesian-style beef meatball with enhanced ber content.

Stabilizers are important component in manufactured products such as yoghurt. The addition of stabilizers improves body, texture, appearance, mouth feel and prevents technical defects such as synersis in yoghurts. In this study starch was extracted from plant sources (sweet potato, taro) with and without use of chemicals. Yoghurt was enriched with different levels of extracted starch. Yoghurt samples were analyzed for physicochemical and functional attributes such as pH, acidity, synersis, water holding capacity, viscosity, total solids and sensory profile. Use of chemically extracted starches at the level of 0.3-0.4% (Sweet potato) and 0.2-0.3% (Taro)   in yoghurt manufacturing showed better  results  in  terms  of  lowering synersis, increasing water holding capacity, viscosity and overall acceptability as compared to the yoghurt containing stabilizer i.e. gelatin 0.5% w/w. Use of starches did not significantly affect the sensory attributes. Yoghurt that contains sweet potato and taro starch at 0.5% gave excellent results for water holding capacity, viscosity and for all sensory attributes as compared to gelatin
