Wastes from the seafood industry can be easily processed into products with new forms of use. The present study was aimed at determining the chemical composition and functional properties of shrimp waste protein concentrate and lyophilized flour. The raw material used in this study consisted of waste (head) of Litopenaeus vannamei. The protein concentrate was obtained by ethanolic extraction, being subsequently submitted to drying in oven at 70° C, while the flour was obtained by lyophilization of shrimp wastes. Moisture, ash, protein and calcium contents showed significant difference between fresh shrimp head waste samples (IN) and protein concentrate and lyophilized flour samples. The protein content for protein concentrate (PC) and lyophilized flour (LF) showed significant increase in relation to protein content in the waste (IN), thus showing that the process for obtaining the protein concentrate was efficient.

The objective of this study was to evaluate, from a technological and nutritional point of view, the chemical composition and functional properties of the industrial winemaking by-products, namely skins, stems and lees. The chemical and physical characteristics, as well as the functional properties (fat and water retention and swelling capacity, antioxidant capacity, and their prebiotic effect), of the dietary fibre of these by-products were studied. The results showed that the skins, stems, and lees are rich in fibre, with the stem fibre containing the highest amounts of non-extractable polyphenols attached to polysaccharides with high antioxidant activity and prebiotic effect. Lee fibre had the highest water retention capacity and oil retention capacity. The results reveal that winemaking by-products could be used as a source of dietary fibre with functional characteristics for food applications.

The current study was included the use of okra seeds (Abelmoschus esculentus) for preparation of Defatted Okra Powder (DOP), Okra Protein Concentrate (OPC) and Okra Protein Isolate (OPI). Three methods were used to identify the best one for protein concentrate preparation . The concentrate with 72.1% protein was prepared by removal of seed peel, ground, defatting and treated with ethanol. The optimum conditions for  protein isolate preparation were 1:40 (water: DOP), extraction time of 75 minutes, extraction pH 9.0 and the precipitation pH was  4.0. This study also investigated the chemical composition to products that were 50.8,72.1,91.2% protein ,0.88,0.86,0.32 % fat ,8.45,9.94,2.67% ash and 35.23,12.37,3.26% carbohydrates For each of DOP ,OPC and OPI respectively. The amount of energy required for protein denaturation were 1.193, 0.5325, 0.236 J / g for DOP , OPC and OPI respectively.

Functional Features

Dietary fibre has a beneficial effect on human health that is manifested, among other things, in a reduced risk of obesity, diabetes or neoplasms. Its numerous functional properties render it a desirable food additive. The objective of the research study was to assess the nutritional and functional properties of a novel rapeseed protein-fibre concentrate (RPFC) developed by a NapiFeryn BioTech company. The chemical composition, including the amino acid composition, and the functional properties of RPFC were compared with those of the soy fibre (SF) and pea fibre (PF) available on the market; the purpose of the comparison was to evaluate the potential of RPFC as a novel ingredient for use in food applications. The research study showed that RPFC contained significantly more protein than SF and PF. At the same time it was found that the level of total dietary fibre in RPFC was similar to the level of this ingredient in SF. What's more, RPFC was characterized by the highest contents of ash and phytic acid. Based on the analysis results of amino acids it was proved that the level of lysine was the highest in RPFC. The RPFC was characterized by a higher content of essential amino acids than PF and a lower content thereof than SF. RPFC was distinguished by good functional features, such as emulsifying activity, emulsion stability, and water and oil absorption capacity. It was showed that RPFC had suitable features to be used as a functional food ingredient in food products.
