The demand for high-quality food products has promoted the study of techniques for its processing and conservation. The present research aimed to evaluate the influence of grilling pretreatment on the physical characteristics of pirarucu fillets and the heat transfer process by a computational modelling, and to optimize the sous vide process parameters. Before and after the sous vide process, the samples were analysed for microbiological, chemical and physical characteristics. There was no significant difference between the total experimental time of grilling and that obtained by computational modelling. Immersion in brine for 300 s in combination with grilling at 200 ℃/120 s was selected because of its water-holding capacity (%) 79.40 ± 0.31, texture (N) 1.91 ± 0.40 and value of L* 74.44 ± 0.38 in the fillets. Cooking at 60 ℃ for 568.8 s were the best sous vide parameters obtained, with highest water-holding capacity (%) 93.60, texture (N) 6.24, Δ E* 7.43, and with microbiological loads below 6 log CFU/g and 7 log MPN/g in the final product. Useful information obtained from this study highlighted the brine and grill pretreatment in combination with sous vide proved it is a potential solution for developing pirarucu products even at an industrial scale.

Abstract Crepes are one of the fast-food snacks from France. Crepes are round pancakes that are folded like a fan and thin. It can be added using chicken meat. This study aimed to determine the physical characteristics and organoleptic of chicken crepes substituted with mocap flour with bamboo shoots. This study used a completely randomized design with six treatments and three replications. There were P0 (rice flour, maize flour, and mocap flour 4.5%, without using bamboo shoot flour); P1 (2.5% mocap flour and 2% bamboo shoot flour); P2 (2% mocap flour and 2.5% bamboo shoot flour); P3 (1.5% mocap flour and 3% bamboo shoot flour); P4 (2% mocap flour and 2.5 percent bamboo shoot flour), P5 (1% mocap flour and 3.5 percent bamboo shoot flour). The data obtained were analyzed using ANOVA and continued using the Duncan Multiple Rate test if there was a significant or very significant difference (P˂0.05). The study concluded that the best treatment was on chicken crapes with P1 treatment (2.5% mocap flour and 2% bamboo shoot flour) from the water content test, Water Holding Capacity (WHC), pick up, hygroscopic and organoleptic. The results of the research on chicken crepes did not affect Water Holding Capacity (WHC) and pick-up values obtained (P> 0.05), while the water content and hygroscopic had a significant effect on chicken crepes with a significance value of 0.001 (P˂ 0.05). The organoleptic test results on chicken crapes significantly affected the texture (P˂0.05). Meanwhile, chicken crepes had no significant effect on color, taste, and aroma (P>0.05).

AbstractThe meat palatability, water-holding capacity, colour and shear force values of 32 Boer goat (BG) kids and 32 South African Mutton Merino (MM) lambs were investigated. Two pelleted diets (offered to 16 animals per species) with either a low (LE, 9·9 MJ/kg dry matter (DM)) or a high (HE, 12·1 MJ/kg DM) metabolizable energy level were given to the animals for either 28 or 56 days. Thereafter the animals were slaughtered, the meat cooked and presented to a trained sensory panel. Organoleptically, a difference between goat and lamb was noted. Each one had a specific species flavour, which was not influenced by energy level of the diet. BG meat was perceived to be stringier than that of the MM, but there was no significant difference in Warner-Bratzler shear force values. Tenderness declined with age in both species and there was also a tendency for goat meat to be less juicy than lamb. Chevon had a more pronounced after-taste than lamb. No objective difference could be distinguished between the colour of the cooked goat and lamb, but there was a tendency for fresh lamb to have a higher a*-value (redness) than goat. Although diet did not influence drip loss, drip loss increased with an increase in slaughter age. Only after 56 days did the m. semimembranosus of MM have a significantly higher drip loss than that of BG (LE: 4·84 v. 3·43%; HE: 4·72 v. 3·23%). In the m. semimembranosus of both species cooking loss increased with an increase in slaughter age. It can be concluded that goat meat compares favourably with lamb in terms of water-holding capacity, colour and shear force values. If goats are finished in the feedlot, it can be done on a LE diet, since diet does not influences any of the mentioned characteristics. This may render a direct economic advantage for BG feedlot finishing.

Broiler chickens (Gallus gallus domesticus) were collected from local chicken suppliers of Dharan (26.8065° N, 87.2846° E), Nepal, and slaughtered to prepare the cut-up parts (breast, drumstick, dorso, wings, and thigh). They were vacuum packed in polythene bags and frozen stored (-21.5 ±3.5ºC) for 45 days to study the effect of frozen storage on the water holding capacity (WHC) of meat. Cooking loss, drip loss, and pH changes were analyzed at 5 days intervals during storage and the data were analyzed using Genstat® v 12.1.The cut-up parts showed a significant change (p<0.05) in pH, cooking loss, and drip loss during 45 days of frozen storage. The pH decreased while the drip loss and the cooking loss increased gradually upon storage. The pH was found to be varied among the cut-up parts with a minimum pH scale of 5.25 for wings, followed by 5.3 for thigh, at the end. The highest drip loss of 6.11% was observed in wings after 5 days of storage which ended up to 8.97% after 45 days of frozen storage while drumstick and thigh samples showed significantly lower drip loss of 6.02%, and 5.43% respectively. The change in cooking loss showed a similar pattern as that of drip loss with a significantly higher value of 37.36% in the breast while it showed no significant difference in drumstick, dorso, and thigh meat. Thus, the study reveals that freezing of broiler chicken meats for a prolonged period adversely affects the WHC of meat

The aim of this study was to evaluate beef quality traits including pH, water holding capacity, cooking loss, meat colour, and Warner-Bratzler shear force in dry-aged beef and to determine the most favorable ageing time based on beef quality parameters and consumer acceptability. In this respect, longissimus dorsi samples were obtained from Simmental bulls and stored for an ageing period up to 21-days, and thus, the beef quality evaluation was performed at 0-day, 7-day, 14-day, and 21-day of the experimental period. Results revealed that the lowest shear force value was observed in beef samples on day-14 whereas the lowest pH value was determined in samples on day 21. Moreover, water holding capacity and beef colour values were significantly differentiated based on dry-ageing (P<0.05). In sensory panel evaluation, a significant difference is found only in meat colour rating (P<0.05). There was no significant difference between ageing periods and cooking loss. The most important technical point is that increasing dry-ageing time from 14 to 21 days did not desirably affect quality traits and sensory scores. Hence, dry-ageing for 14 days seemed to be the most economically efficient application. Taken altogether, the present results suggest that the potential for use of dry-ageing should be considered as an alternative method to produce high-quality beef with respect to the optimum ageing process.

Carp (Cyprinus carpio) is a freshwater fish with high economic value and good farming potential. Carp-based product diversification could be done by using it as food ingredients such as surimi in sausage manufacture. This research was aimed to evaluate sausage produced from carp surimi by varying washing frequency and tapioca filler concentration. Five washing frequencies (1; 2; 3; and 4 times) and three tapioca filler concentrations (2; 3; and 4%) were compared. The study showed 1 time washing frequency gave better surimi physical characteristics (57.40% yield; 73.76% water holding capacity; 26.64% expressible moisture content, 821.92 g.cm gel strength; 54.45% whiteness) and chemical characteristic (78.00% moisture content and 6.34% salt soluble protein) compared to other washing frequencies. Based on the organoleptic test, 2% tapioca was the selected filler concentration. Selected surimi sausage had better physical, chemical and sensori characteristics than commercial sausage. The physical characteristics of the selected sausage were 70.46% water holding capacity; 24.58% expressible moisture content; 78.64% whiteness; 4346.70 g.cm gel strength; 101.23 g hardness; 0.98 g springiness; and 43.96 g chewiness. While the chemical characteristics of that sausage were 75% water; 1.35% ash; 11.51% protein; 4.46% fat; and 7.63% carbohydrate. The sensory scores of the sausage evaluated were color 0.44, aroma 0.60; taste 1.16; and springiness 1.86.

Three white sorghum varieties (named ‘Dorado’,‘Shandaweel-6’ and ‘Giza-15’) were investigated for grain characteristics and processed whole meal flour (via soaking, cooked, germinated and fermented sorghum). ‘Giza-15’ variety was the highest one in 1,000 kernel weight and hectolitre, followed by ‘Dorado’ and ‘Shandaweel-6’ that were significant lower. Sorghum varieties were non-significant different in L scales. ‘Giza-15’ was the highest variety in a and b scales. Sorghum varieties were significant different in c scales and non-significant different in h scales. Shandaweel-6 recorded the highest value in water holding capacity (WHC).‘Giza-15’recorded the highest variety in oil holding capacity (OHC). The most significant increase in WHO was after fermentation treatment, followed by cooking treatment. Regarding OHC, the most significant increase was after germination treatment. Biscuits prepared from 50% whole meal flour of raw, soaked, cooked, germinated and fermented sorghum were evaluated for sensory and physical characteristics. The sensory results showed that 50% sorghum whole meal flour could be incorporated to prepare acceptable quality biscuits. The diameter of sorghum biscuits increased, while the diameter of wheat biscuits decreased. Hardness of sorghum biscuits was significant decreased in all treatments compared with wheat biscuits. Hardness of germinated sorghum biscuits was close to wheat biscuits values.
