Nga-pi, an ethnic fermented product traditionally produced at Cox’s Bazar region by Rakhine people is one of the popular food items of that area. To assess the quality of raw shrimp used for Nga-pi production and traditionally produced Nga-pi were collected. Some amount of the collected Nga-pi sample (from producers of both areas) were stored at refrigeration temperature (5 to 8°C) for 90 days to observe the changes in nutritive values, TVB-N and SPC during the storage. The results of proximate composition analysis for the samples showed that-the moisture content ranged from 58.29% to 61.06%, the crude protein content ranged from 25.88% to 27,12%, the crude lipid content ranged from 4.18% to 5.12% and ash content ranged from 7.30% to 8.40%. On the other hand the range for TVB-N value was found from 25.06 mg/100g to 34.02 mg/100g and SPC value from 1.69×105 CFU/g to 4.27x 106in Nga-pi samples. The result of the Nga-pi sample stored in air-tight polythene pack at refrigeration temperature (5 to 8°C) for 90 days showed that- the percent moisture, percent ash content, TVB-N value and SPC value increased but the percent protein and lipid content decreased with the progress of storage time.

The aim of this study was to investigate the potential effects of the harvesting season and fish size on the final quality of cage farmed gilthead sea bream (Sparus aurata). Morphometric analysis, fat stores estimation, fillet composition analysis, fillet fatty acids profile determination and sensory analysis were carried out on a commercially-sized cage farmed gilthead sea bream (Sparus aurata L.) population in April, June, July and November. Both season and size had a significant effect in morphometric characteristics. The most pronounced size effect was the change of fish shape, becoming rounder with fish growth, the increase of filleting yield and condition index. An increase of both peritoneal and perivisceral fat was observed in summer months. In general size had little effect on muscle composition. A significant size effect was observed in the fillet lipid content, which increased with it. Fillet lipid content was unexpected lower in the warm period (June-July). This can be possibly attributed to feeding restrictions that may have occurred, due to anoxic incidents related to high temperatures.Slight seasonal differentiations occurred in the muscle fatty acids. No significant differences were found in the organoleptic characteristics of the two size groups compared.

Kishk is a dried mixture of fermented milk and cereal, widely consumed in Upper Egypt. The aim of this study was to study the effect of rye, sorghum with wheat grains compared with traditional wheat kishk (control) on physical properties, chemicals composition, microbiological and sensory analysis. Untraditional kishk was prepared with rye, sorghum and four groups of mixtures Mix1 (50% wheat and 50% rye), Mix 2 (50% wheat and 50% sorghum), Mix3 (50% rye and 50% sorghum) and Mix4 (mixed of wheat, rye and sorghum in ratio of 1:1:1) compared with traditional wheat kishk. The chemical composition analysis of different untraditional kishk was in the following ranges: moisture content of kishk samples ranged from 8.00 to 12.72% for M 2 and M 1, respectively. M 2 had the highest total solid of untraditional kishk samples value 84.66% while Mix 1 had the lowest value 76.18%. For protein content, wheat had the highest protein 27.11% followed by M 1 (26.02%), while sorghum (22.90%) had the lowest protein content. On other hand nitrogen free extracts (NFE) % range from 65.76% (rye) to 80.55% (wheat). Additionally Sorghum had lower fat (2.50%) than other samples and wheat was lower in ash content 6.64% in completely in other untraditional kishk. The results of fiber showed that rye had significant highest value of 8.12% while wheat had lowest value of 1.80%. M 3 was the lowest total caloric values 325.13% of kishk samples and tannic acid was under detection safe limit 0.185%. Data also indicated that as a result of pH of different prepared kishk samples. Microbiological analysis of kishk from wheat, rye, sorghum and their mixture were determined. M1 kishk is white and yellow colored than other untraditional kishk samples. Differences in sensory attributes were associated with different grain kishk and their mixed but there were no significant differences between wheat kishk control and M 1 in mouth feeling, and consistency. Sensorial, M1 kishk is more acceptability than other treatment after the traditional kishk control.

This research aimed at investigating the effect using molasses and cornmeal as additives with Lactobacillus sp. and Streptomyces sp. as inoculums during fermentation on the quality of silage flour made from dead chickens. The study was conducted using a completely randomized factorial design, consisting of 2 factors with 5 replications. The materials used were the newly dead chickens which were chopped and mixed thoroughly with all ingredients; then transferred into a 5 liters plastic box for fermentation. Observations were made after 3 weeks fermentation, including: a) physical characteristics, b) microbial contents, and c) nutritional contents. The data were calculated using variance analysis utilizing computer program of SPSS version 21.0. It was found that based on the protein contents the Lactobacillus sp. (19.0%) was better than the Streptomyces sp. (17.8%) if combined with molasses and corn meal as the accelerators. However, the fat contents produced were relatively similar for both of the inoculums (mean of 37.8%). It can be concluded that in order to obtain a best fermented product in terms of the protein and fat content, the dead chicken should be fermented using molasses and cornmeal as the accelerator and Lactobacillus sp. as the inoculum.

Abstract Possibilities of using electric methods for determining admixtures of oat meal to wheat flour, type 650 are presented. In wheat flour, oat meal and mixtures containing 10, 20 and 30% of the oat meal, moisture, protein, starch and ash content, sedimentation value, yield and softening of wet gluten were determined. In samples containing 0, 5, 10, 15, 20, 25, 30 and 100% of oat meal, the dielectric loss factor and conductivity were determined using an impedance analyzer for electromagnetic field frequency ranging from 0.1-20 kHz. It was found that the dielectric loss factor varied for tested material. The best distinguishing between tested mixtures was obtained at the measuring electromagnetic field frequency of 20 kHz. The loss factor was significantly correlated with the yield of wet gluten and the sedimentation value, parameters indicating the amount and quality of gluten proteins in flour.

The influence of different drying methods on physical and nutritional properties of shrimp meat was investigated in this study. Peeled shrimps were dried separately using an air-oven dryer and a tunnel solar dryer. The drying profile of shrimp meat was determined in the two drying systems by monitoring moisture loss over the drying period. Changes in color, proximate composition, and rehydration capacity were assessed. The rate of moisture removal during solar drying was faster than the air-oven drying. The development of red color during drying was comparable among the two methods, but solar-dried shrimps appeared darker (L⁎=47.4) than the air-oven-dried (L⁎=49.0). Chemical analysis indicated that protein and fat made up nearly 20% and 2% (wb) of the shrimp meat, respectively. Protein and ash content of shrimp meat dried under the two dryer types were comparable but fat was significantly (p<0.05) higher in oven-dried meat (2.1%), compared to solar-dried meat (1.5%). Although rehydration behavior of shrimp from the two drying systems followed a similar pattern, solar-dried shrimp absorbed moisture more rapidly. The results have demonstrated that different approaches to drying may affect the physical and nutritional quality of shrimp meat differently.

ABSTRACT: This study evaluated the yield, color, and chemical composition of commercial cuts (tail, sirloin cut, back fillet, and thigh) of Pantanal caiman meat in both sexes. The yield of tail was higher than other cuts, and the yield of females (17.0%) was higher than males (15.9%). The thigh of males had lower protein content (20.8%) compared with other cuts. Females showed a higher lipid content in the tail (2.4%) and thigh (0.8%) compared with males (1.7% and 0.4%, respectively). The tail presented the greatest content of monounsaturated fatty acids (45.2%) and higher n6/n3 ratio (4.6). Although lightness was not different among cuts or between sexes, there were differences in color. Males have more yellowish meat compared with females. Thigh and back fillet were more reddish when compared to sirloin cut and tail, regardless of sex. In conclusion, female tail meat provided greater yield and lipid content than males, and this result was statistically significant. These findings can help producers and consumers alike, better understand yield, quality, and nutritional quality of Pantanal caiman meat.

The study was conducted in aims to investigate the effects of frozen storage and cooking conditionson proximate compositions and formaldehyde content (FA) in some selected fish from three different sourcesin Bangladesh. Proximate composition in fresh and final frozen samples was determined by standard AOACmethod and FA content in fresh, frozen stored, and cooked samples was determined by spectrophotometricmethod. Among the studied fishes, marine fish contained higher protein (except Rita), lipid, and ash followedby estuarine and culture fish samples. Protein, moisture and ash content decreased and lipid content increasedsignificantly (p<0.05) during frozen storage for all samples and sources. The FA was lower in cultured fishsamples compared to that of the river and marine fish samples, both at fresh and end of frozen storage. Atfresh condition, FA content in all samples ranged from 0.41 to 0.71µg/g, 0.51 to 0.89µg/g, and 0.73 to1.69µg/g which increased to 0.95 to 2.11µg/g, 1.74 to 1.95µg/g, and 3.22 to 5.20µg/g at end of the storageperiod, respectively (p<0.05). Further, FA content significantly decreased after cooking in all the fishsamples (p<0.05). However, irrespective of fish species and sources, the FA content was higher than WHOrecommended value (0.2 µg/g). The study findings revealed that longer frozen storage of fish could be apublic health concern to the consumers.

“Soumbara” is a fermented product sold in the markets of several West African countries. In the markets, it is sold in several formats (granulated, powder, and paste). The objective of this study was to evaluate the microbiological and physicochemical characteristics of these three types of “Soumbara” sold in the Korhogo markets. For this purpose, a preliminary survey followed by a sampling of 54 samples of “Soumbara” was carried out. The microorganism load count was carried out according to microbiological standards. The pH, titratable acidity, and moisture content were measured, respectively, with a pH meter, by dosing with sodium hydroxide solution and by differential weighing after passing the sample through the oven. The pH of the different samples is around 6. The moisture content is higher in “Soumbara” paste (20-24.7%) than in powdered (7.3-9.3%) and granulated (8.6-10.7%) “Soumbara.” The acidity rates are between 0.07 and 0.13%, 0.2 and 0.3%, and 0.08 and 0.1%, respectively, for the granulated, powder, and paste types. Mesophilic aerobic germ loads (6.17-8.38 log10 cfu/g) for all three types of “Soumbara” are above the standard. Total coliform (1.13-2.96 log10 cfu/g), mould (0.86-2.52 log10 cfu/g), and yeast (0.33-1.53 log10 cfu/g) loads are below standard. The microbiological quality of the three types of “Soumbara” is unsatisfactory. Overall, “Soumbara” powder is the most contaminated, followed by granulated and paste “Soumbara.” “Soumbara” must be added during culinary preparations in order to avoid possible public health problems.

This study investigated some key processing steps of fermented acerola juice, including variety, maturity, enzyme treatment, sugar concentration and fermentation and pasteurization conditions. One or two-factor experiments were randomly designed to determine the most suitable processing variables based on the investigated parameters, including the content of vitamin C, sensory quality and physicochemical properties of the resultant juice. The results showed that the Brazil variety (Malpiphia emarginata D.C) had highest vitamin C content (1567.9 mg/100 g), followed by sour variety (Malpiphia glabra L.) (882.9 mg/100 g) and sweet variety (Malpiphia punicifolia L.) (630.4 mg/100 g). However, according to sensory evaluation results, the sour acerola juice after fermentation had the highest overall score, indicating to be the most suitable for processing. The fermented juice of sour acerola variety at 100% maturity had the highest sensory score and vitamin C content compared to other levels of maturity. In order to enhance the clarity of acerola juice, the addition of 0.15% pectinase enzyme (Pectinex ultra SPL, Novozymes) was the most effective compared to 0.05 and 0.1% (w/w) enzyme concentrations. The fermentation at 15oC in 48 hours with 22% sugar concentration and 0.1% commercial yeast (Saf-instant, France) obtained the highest quality fermented juice. The fermented product was pasteurized at 80oC for 10 minutes to stop fermentation process as well as to retain the color and taste of the fermented juice. The good quality of the fermented acerola juice, in terms of physicochemical, sensory and microbiological properties could be maintained for at least 6 months.
