Experiments were conducted to evaluate quality attributes of biscuits using wheat, sorghum and groundnut blend flour. Study was also conducted to see the effect of blend flours treatments on textural characteristic and sensory evaluation. Flours blend were prepared with various combination of wheat, sorghum and groundnut as W80: S15: G05 (T1), W70: S20: G10 (T2) and W60: S25: G15 (T3). Textural characteristics viz., fracturability, hardness, cohesiveness, adhesiveness through texture analyzer. The sensory characteristics viz., colour, odor, flavour, taste, texture and overall acceptability were evaluated for fresh, 30, 60 and 90 days of storage period. The maximum hardness was found in sample prepared for treatment T2 (2752.70 g), whereas higher cohesiveness value was obtained in sample of treatment T1 (1.67). The adhesiveness and springiness were obtained maximum in sample of treatment T3 (8.47 g.s) and treatment T2 (2.09 mm), respectively. The gumminess and chewiness value were found highest in sample of treatment T2 (4349.26 g) and treatment T2 (9056.48 g.mm), respectively. Sensory characteristics as colour, odor, flavour, taste and overall acceptability were scored highest rating in T2 treatment as compared to T1 and T3 treatments. Sensory score was decreased with increase of storage period in all treatments. Fresh biscuit samples prepared with wheat 70% + sorghum 20% + groundnut 10% rated highest score (7.8) than other treatments. The treatment (T2) gave better product in view of colour, odor, flavour, taste and overall acceptability as well as textural quality attributes.

The aim of this study is to use of karkede (Hibiscus sabdariffa L.) byproduct as raw material to make ketchup instead of tomato. Ketchup is making of various pulps, but the best type made from tomatoes. Roselle having adequate amounts of macro and micro elements, and it is rich in source of anthocyanine. The ketchup made from pulped of waste of soaked karkede, and homogenized with starch, salt, sugar, ginger (Zingiber officinale), kusbara (Coriandrum sativum) and gum Arabic. Then processed and filled in glass bottles and stored at two different temperatures, ambient and refrigeration. The total solids, total soluble solids, pH, ash, total titratable acidity and vitamin C of ketchup were determined. As well as, total sugars, reducing sugars, colour density, and sodium chloride percentage were evaluated. The sensory quality of developed product was determined immediately and after processing, which included colour, taste, odour, consistency and overall acceptability. The suitability during storage included microbial growth, physico-chemical properties and sensory quality. The karkede ketchup was found free of contaminants throughout storage period at both storage temperatures. Physico-chemical properties were found to be significantly differences at p?0.05 level during storage. There were no differences between karkade ketchup and market tomato ketchup concerning odour, taste, odour, consistency and overall acceptability. These results are encouraging for use of roselle cycle as a raw material to make acceptable karkade ketchup.

Background: The extrusion cooking is the most widely used process so the development and consumption of extruded snack products having health and nutritious benefits would help increase the health status of the population. Objective: The aim of this study was to investigate the effect of storage days on physical, microbial activity and sensory characteristics of extruded snacks and kinetics of extruded snacks. Methods: Extruded snacks were produced by extrusion cooking at optimized conditions of temperature, moisture and screw speed of 110°C, 12% (db) and 200 rpm. The products were packed in lowdensity polyethylene (LDPE) and laminated pouches (LP) and were stored at an accelerated temperature condition of 40 ± 2°C. The storage stability in terms of quality parameters such as moisture, hardness, bulk density, color, lateral expansion, sensory characteristics and total plate count was investigated. Results: An increase (p≤0.05) in the value of moisture, bulk density, a*, and total plate count was observed during the storage period, whereas hardness, L*, b*, ΔE and sensory characteristics showed significant (p≤0.05) decreased order with storage period. No significant effect on the lateral expansion of the extruded product was observed. A significant decrease in total carbohydrate, fat and protein content was found during the storage period. The average sensory score and microbial analysis suggested that extruded snacks packed in LDPE pouches can only be acceptable up to the 60th day and extruded snacks packed in LP can be acceptable to more than 90th day. The kinetics of color and hardness suggest first order kinetics. Conclusion: Overall investigation suggested that extruded snacks were more stable in the LP as compared to LDPE pouches.

The study was conducted with the aim of processing and developing ready to cook jackfruit to evaluate their nutritional and sensory quality attributes. In this study, green tender jack fruits were harvested from 60 to 70 days after synthesis. Then the fruits were washed, peeled and cut into slices. The slices were treated by dipping into different solutions for each treatments viz. control (T1), 0.5% salt solution (T2), 0.2% citric acid solution (T3), 1000 ppm potassium metabisulfite (KMS) (T4), 1000 ppm KMS + 0.5% salt (T5), 1000 ppm KMS + 0.2% citric acid (T6), 0.5% salt + 0.2% citric acid (T7) and 1000 ppm KMS+ 0.2% citric acid+ 0.5% salt (T8). Then the treated sliced was steam blanched at 85°C temperature for 8 min. The roasted beef spices were mixed and then dried at 50°C, 60°C and 70°C temperature owing to preparation of ready to cook. Results revealed that ready to cook dried at 50°C, 60°C and 70°C temperature took 72 hrs, 48 hrs and 36 hrs respectively. Low potassium metabisulfite residue was observed with increasing blanching time and drying temperature. The physicochemical characteristics, phytochemical and antioxidant activities were retained more and the highest sensory score was obtained at 60°C temperature. The marketable life of the RTC jackfruit could be extended to more than 6 months. However, the findings suggest that green tender jackfruit treated with 1000 ppm KMS, blanched for 8 min and dried at 60°C is a quick and healthy option in terms of good marketable life, nutritional and sensory quality attributes.

A study was carried out from 1st July to 21st October 2003 at the Institute of Animal Science (IAS), University of the Philippines, Los Baños, College Laguna, Philippines. The study was based on the overall acceptability of substitution of sodium chloride by potassium chloride, frankfurters of broiler chicken and buffalo meat, which were prepared with or without garlic at 1:1 ratio. Frankfurters stored in chiller for over-night after the preparation (as fresh) and stored in freezer (-5 to -7°C) were taken out at 45 and 75 days for sensory evaluation. Ten experienced panelists were involved to evaluate sensory characteristics of frankfurters. Required amount of franks were cut into approximately 2.5 cm size and heated in microwave before serving to the panelists after randomly coding. Each panelist was served with four randomly allocated samples such that in each replication (block), two panelists were assigned. Juiciness, tenderness, color, flavor, off-flavor and overall acceptability were evaluated using the seven point Hedonic scale score card. Type of meat used and the storage period had significant influence in some of the sensory traits, such as juiciness, tenderness and color. Scores for juiciness and tenderness were significantly (P>0.05) higher with chicken franks. However, highly significant (P>0.01) difference was observed for color, favoring buffalo meat franks. Traits such as flavor and overall acceptability had higher scores for chicken than buffalo meat, although scores for offflavor had opposite values; higher with chicken, but was not significantly different. Sensory characteristics for stored products were scored lower than fresh. Color was influenced significantly (P>0.05) by meat type, salt, garlic and also storage period of 75 days. Meat type and storage interaction had significant (P>0.05) differences on juiciness, overall acceptability and tenderness. However, their effects as individual variable were not significant. When garlic was used at 2% level in combination with NaCl+KCl at 1:1 ratio the effectiveness was more pronounced from all respects. However, same percentage of garlic could not produce more acceptable franks with sodium chloride alone. All sensory parameters considered in the study were scored less either for 45 or 75 days storage than the fresh. However, statistically; except for off-flavor, no significant differences were observed between 45 and 75 days.

The influence of pre-fried time and temperature on the cooking yield, shear force, color and sensory quality of microwave beef kebabs were evaluated. The beef kebabs were fried for 20 s, 40 s, 60 s and 80 s at 170 ± 2 °C, 180 ± 2 °C or 190 ± 2 °C in the fryer. The results revealed that beef kebabs fried at 190 ± 2 °C for 60 s had significantly higher cooking yield, shear force, redness (a*), yellowness (b*), flavor, color and overall acceptability than the samples fried at 170 ± 2 °C and 180 ± 2 °C for 60 s. Lightness (L*), juiciness and tenderness of beef kebabs fried at 190 ± 2 °C for 60 s were lower than samples fried at 170 ± 2 °C and 180 ± 2 °C for 60 s. In addition, the cooking yield values fried at 190 ± 2 °C for different times was increased by 4.58%, 3.49%, 2.37% and 1.12% over that fried at 170 ± 2 °C. Beef kebabs fried at 190 ± 2 °C for 60 s promoted the color and cooking yield remarkably and had a beneficial effect on sensory characteristics during frying. The optimum frying parameters of kebabs were at 190 ± 2 °C of oil temperature for 60 s of frying time.

This study investigated the nutritional, microbial, and sensory quality attributes of a fermented milk (laban) drink flavored with date syrup (dibs) during cold storage at 4 °C for 7 days. Date syrup was added to laban in specific proportions (2.5, 5, 7.5, 10, 12.5, and 15% date syrup/total weight of flavored laban) and an appropriate percentage (12.5%, 74 °Bx) was selected based on the sensory preference of panelists. The results indicate that flavoring laban with date syrup affected the physicochemical, nutritional, microbial, and sensory quality attributes of the product in different ways. Incorporation of date syrup in fresh laban drink significantly increased the pH, ash, protein, total solids, sugars, and magnesium (p < 0.05). However, acidity, fat, casein, lactose, calcium, total microbial count, and total yeast and molds count were decreased (p < 0.05). During storage, acidity, ash, and microbial load were concomitantly increased, while fat, casein, total solids, and sugars showed a concurrent reduction as the storage period progressed. The panelists preferred the freshly prepared flavored laban drink compared with the stored one, which is not surprising. After 7 days of storage, flavored laban drink was more acceptable than a non-flavored one. The findings of this research will help in fortifying dairy products with dates to create highly nutritious drinks without the addition of artificial additives, refined sweeteners, and preservatives, which at the same time would be accepted by consumers.

<p>Cowpea seeds can be cooked in the dried form, sprouted, or ground into flour. This study is to investigate effect of soft-sterilization and nano-ZnO treatment on canned cowpea (TN 5-78) biophysical and quality attributes during 10 months of storage. Cowpea was blanched, ultrasonicated with nano-ZnO solution 0.025% (w/v) added prior to canning at 110 ºC for 15 min and analyzed every 2 months up to 10 month at ambient storage. Total mold and yeast count were below the limits of detection for nano-ZnO treated samples and control over the storage period though, some colonies of mesophilic bacteria were observed in the untreated samples at the 8th and 10th month of storage. There are significant differences (P &lt; 0.05) between the treated samples and untreated one at the 10th month of storage for the pea’s firmness. No significant differences was noticed between the samples from the initial analysis to the end of storage time for the leached solids percentage (P &lt; 0.05). Moreover, slight change in protein content and pH values were also found. The overall acceptability score of nano-ZnO treated samples remained in a good range up to 10<sup>th</sup> month of storage whereas, untreated samples was under acceptation level. Therefore, ZnO nanoparticules combined with heat can be a possible alternative approach to can foods that the quality attributes are altered by conventional thermal sterilization.</p><!--[endif] -->

Cashew has commercial value for its nut and peduncle (false fruit), known as cashew apple. Requirements of consumers considering convenience, food safety, health benefits and sensory quality have increased demand for fruit juices, but most consumers don’t get time for the ready to use products. Instant juice powders can meet consumer requirements being cheap to transport and with prolonged shelf life. Then the blended juice was mixed with maltodextrin @15 per cent, i.e., 15 g for 100 mL of blended juice by proper homogenisation. The roots of the sugandi (Swallow root - Decalepsis hamiltonii) were collected, cleaned thoroughly and discarded the central white portion of the roots. Among the blended juice treatment combinations, the highest pH of 3.45 was recorded in B3 (75% cashew apple juice + 25% pineapple juice powder at 150°C inlet temperature with a flow rate of 10 mL min-1). The ready-to-serve (RTS) beverage, along with sugandi stored under refrigerated condition, were free from microbial proliferation till the end of the storage period (60th day of storage), indicating its fitness for consumption with maximum flavour, taste and overall acceptability.

Storage stability of raw chevon (goat meat) chunks wrapped in preformed, bioactive, biodegradable films based on composite starch–chitosan and impregnated with nisin (60 000 IU/g; T-1) and cinnamaldehyde (0.5% v/v; T-2) was evaluated relative to unwrapped product (control) under aerobic refrigeration (4°C ± 1°C) conditions for 10 days. Samples were taken on Days 1, 4, 7 and 10 to assess various physicochemical, microbiological and sensory quality parameters. Water activity and pH of raw chevon chunks followed a decreasing trend during storage under all packaging conditions; the rate of decrease of water activity was higher (P < 0.05) in the control than in bio-packaged products. Values of thiobarbituric acid reactive substances increased throughout storage and were lowest in T-2 and highest in the control. Extract release volume decreased throughout storage under all packaging conditions; however, it was higher (P < 0.05) in bio-packaged products than the control. Microbial quality was better in bio-packaged products than the control throughout storage. Standard plate count was 2.09 log10 cycles lower in T-2 than the control, and coliform count was lower by log10 2.31 cfu/g in T-2 and log10 1.88 in T-1 than the control on Day 7 of storage. Staphylococcus counts were lower (P < 0.05) in bioactive-packaged products than the control throughout the storage period. Sensory quality attributes colour, odour, texture and overall acceptability were better maintained in bio-packaged products than the control during storage, and maximum scores were awarded to T-2. The results indicate that starch–chitosan composite films impregnated with cinnamaldehyde can be used for the packaging of raw goat meat and successfully extend storage life by inhibiting the colour, oxidative and microbial deteriorative changes under refrigeration.
