This study evaluates the nutritive value of some fast products made from silver carp fish (Hypophthalmichthys molitrix), in Lake Wadi El-Rayan, El-Fayoum, Egypt. The average weight (M± SD) of three fish samples during February, 2012 was 17.5 ± 0.300 kg and the edible part was 53%. Fast silver fish products such as fish fingers, patties, kofta and chips were nutritionally and sensory evaluated. The obtained results indicated that protein level in fish fingers was higher than other ones, fish patties had a high fat content and energy valueو while, kofta and chips had a high content of carbohydrates. Essential amino acids (EAA) content (g/16gN) of all products was much higher than FAO/WHO (1985) reference protein pattern. Also, amino acids score (AAS) for all EAA was higher than 100. Therefore, the best nutritional protein quality was found in fish fingers followed by patties, kofta and chips products respectively. However, fish patties had been obtained high scores of sensory evaluation followed by fish fingers, kofta and fish chips respectively. The mean scores of odor and acceptability were significantly higher (P≤0.05) in all products. In conclusion, silver carp fish in Lake Wadi El-Rayan can be reaching to unacceptable sizes for fresh marketing, so, it could be utilized to produce some fast products. The nutritional protein quality of studied products varied markedly as affected by fish mince percent in formula used for each product.
Greengram [Vigna radiata (L.) Wilczek], popularly known as mungbean, is third most important pulse crop of India. Mungbean is a cheap source of dietary protein for the poor, with high levels of folate and iron compared with many other legumes. Variability is low available in mungbean and hence, to replace conventional breeding, mutation breeding has gained its momentum. Induced mutagenesis thus seems to be an ideal methodology for the induction of desirable genetic variability. Chlorophyll mutations, an important index in the estimation of induced genetic changes in mutagen treated population are most widely employed for assessing the potentialities of mutagens in creating genetic variability. An investigation was carried out in two mungbean genotypes CO (Gg) 7 and NM 65 treated by two mutagens viz., gamma rays and ethyl methane sulphonate. A wide range of chlorophyll mutations was observed and scored in M 2 generation. The highest frequency rate was noted at 300 Gray and 10 mM on M 1 plant basis and M 2 seedling basis in both the genotypes. The mutant chlorina and xantha occurred in all the treatments of gamma rays and EMS at higher proportions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
