Biological Value

The current constant pressure on fishmeal production for aquaculture feeds stresses the need to search for alternative sources of protein. A possible protein ingredient is insect meal, being more cost effective than fishmeal and soybean meal. Black soldier fly (Hermetia illucens) larvae meal is used in many studies with positive results regarding the bioproductive performances of salmonids. The balanced amino acid profile is comparable with the one of soybean meal. The crude protein and amino acid digestibility is high and similar to that of fishmeal. For rainbow trout (Oncorhynchus mykiss), the protein biological value of the larvae is qualitatively lower than that of fishmeal. Atlantic salmon fed with experimental diets with larvae meal showed high bioproductive performances and a better protein biological value compared with salmon fed with a standard fishmeal diet. However, the nutritional quality and chemical composition of the larvae can be drastically improved through the feeding media, which make it a very interesting candidate as a substitute for fishmeal. The aim of this review is to present the current stage of H. illucens use in salmonid feeds, detailing the chemical composition and protein quality. Furthermore, the effect of larvae meal based diets on salmonids is presented.

Abstract The aim of this study was to evaluate the compositional and nutritional potential of methanolic extracts of various parts of Acacia leucophloea Roxb. concerning the chemical composition and antioxidant potential of which limited information is available. Compositional studies indicated carbohydrates as major components in both seed and pods. Despite differences in mineral content among the leaves, pods and seeds, calcium was found in the highest amount and zinc in the lowest. The amino acid profile indicated aspartic acid as the major amino acid and proline as the minor. Among protein fractions, globulin was present in higher amounts than other fractions. Linoleic acid was the major fatty acid detected in the oil from both pods and seeds, while g-tocopherol was the major component of the tocopherol observed from same oil. Moreover, significant antioxidant potential was observed from the extracts of all three parts investigated. The results obtained in this study clearly indicate that A. leucophloea has a sufficient potential for use as a natural antioxidant agent. Further phytochemical studies will be performed for specification of the biologically active principles.

Roe has a high protein content and a number of amino acids. The process of removing fat and hydrolyzate with enzymes leads to the breaking of the bonds, so that complex proteins are converted into short chain proteins or peptides and free amino acids. The peptide can act as bioactive and has an effect as antihypertensive, antibacterial, antioxidant and so on. This research was aimed at utilizing processed roes to make hydrolyzate which had previously viewed the chemical composition both fresh and defatted, and to determine the protein profile of the roes from hydrolyzate. The research data were analyzed descriptively,  and the average value and standard deviation were calculated. The results showed that skipjack roes have a fairly complete chemical composition, such as Proximate (protein, fat, moisture, ash, and carbohydrates), with values, respectively 19,19%, 0,67%, 76,32%, 2,51% and 1,31%. It was also found that the dominant amino acid composition of defatted skipjack mature roes is lysine, glutamate and leusine with values, respectively 12.65, 11.20 and 7.72 g/100 g protein and have activity as an angiotensin converting enzyme inhibitory. The ACE inhibitory activity of Skipjack roe hydrolysates of crude papain enzyme from immature and mature value, respectively 36.62% and 38.82%, while pure papain enzyme from immature and mature value respectively 42.63% and 47.54%. The protein profile of the immature roe hydrolyzate range from 10.88 to 125,80 kDA, while the mature roe hydrolysates range from 10.08 to 125,30 kDa.
