“…Next, the samples were defrosted and separated from solid tissue fragments by centrifugation at 6000 G for 15 min [15]. The supernatants were freeze-dried to 5.0 ± 0.2 % residual moisture according to the previously described procedure [16]. The residual moisture was controlled by its measuring using the Karl Fischer volumetric titration method with METTLER TOLEDO DL31 automatic titrator.…”

Antioxidant activity of freeze-dried Siberian sturgeon (Acipenser baerii) ovarian fluid

et al. 2023

Ovarian fluid is a mass-production nutritionally valuable byproduct of aquaculture of sturgeons. Total antioxidant activity of freeze-dried pasteurized and non-pasteurized ovarian fluid of Siberian sturgeon (Acipenser baerii) was determined to estimate its potential acceptability as an anti-inflammatory and anti-age agent in nutraceuticals. Total antioxidant activity was determined using the certified coulometric measurement method. The value of total antioxidant activity was about 18.6 ± 1.1% of that of a well-known source of antioxidants – tomato fruits, if calculated by dry weight. There was no statistically significant difference between the values of activity for pasteurized and non-pasteurized ovarian fluid, so it is reasonable to pasteurize the fluid for its preservation.

Nutritional value of black solder fly (Hermetia illucens) eggs and larvae reared on fermented milk industry waste as an ingredient of fish feed

et al. 2022

Eggs and larvae of the black soldier fly are a new protein and lipid containing component, which seems to be quite promising for inclusion in a diet for fish feeding, since its rearing makes it possible to process wastes from various industries and agriculture. Omnivorous natures of black soldier fly, as well as high activity of amylases, lipases, and proteases are also advantageous. The nutritional value of eggs and larvae reared using fermented milk industry waste as a substrate was assessed by the content of total fat, total protein, water, macronutrients (K, Ca, Mg), micronutrients (Fe, Cu, Mn, Zn, Co, Se), and by amino acid composition as well. Chemical analysis has shown that the larvae are nutritionally valuable in total, but further data on fatty acid analysis and vitamin content are required. Black soldier fly eggs are not nutritionally valuable as a complete feed but may be used as a component of a diet.

Malnutrition is one of major factors of bone and cartilage disorders. Pacific cod (Gadus macrocephalus) processing waste is a cheap and highly promising source of bioactive substances, including collagen-derived peptides and amino acids, for bone and cartilage structure stabilization. Addition of these substances to a functional drink is one of the ways to achieve their fast intestinal absorption. Collagen hydrolysate was obtained via enzymatic hydrolysis, ultrafiltration, freeze-drying, and grinding to powder. The lyophilized hydrolysate was a light gray powder with high protein content (>90%), including collagen (about 85% of total protein) and a complete set of essential and non-essential amino acids. The hydrolysate was applicable as a protein food supply or a structure-forming food component due to presence of collagen fiber fragments. An isotonic fitness drink (osmolality 298.1 ± 2.1 mOsm/L) containing the hydrolysate and vitamin C as a cofactor in collagen biosynthesis was prepared. Addition of the hydrolysate did not adversely affect its organoleptic parameters. Production of such functional foods and drinks is one of the beneficial ways of fish processing waste utilization.
