By-products of the production of biologically active additives from seaweed for creation products of functional orientation

 

In modern society are experiencing increasing demand for the products of marine origin, which include and seaweeds.

Brown algae growing in the coastal waters of Far East of Russia - a source of vitamins, minerals, polysaccharides, and other biologically active substances, which determined the creation on their basis of biologically active additives (BAA) to food, food products and other preparations for medicine, cosmetics, agriculture [3].

By the scientists of laboratory of chemistry enzymes PIBC FEB RAS developed a method of complex processing of brown algae Fucus - Fucus evanescens, which has a universal character and allows you to get a variety of BAA (Fukolam - C Fukolam) [2].

With BAA on the basis of fucus created lineup of food products with therapeutic and preventive orientation - bakery products, fat products, milk products [4, 5].

The existing method for complex processing of algae to produce BAA Fukolam on first stage involves pre (degreasing) treating the raw material with ethanol, whereby produced  water-ethanolic extract [4].

When studying the chemical composition of the water-ethanolic extract of Fucus, it was shown that it is composed of mineral substances and nitrogen, oligosaccharides, mannitol, polyphenolic compounds and lipophilic substances, ions of iron, cobalt, manganese and nickel, phenolic compounds and chlorophyll. In this extract Fucus evanescens has a higher concentration of trace elements of iron, cobalt, manganese and nickel than other extracts of seaweeds, which is probably due to growing seaweeds in shallow water under good lighting conditions, which increases the accumulation of iron and other trace elements in the tissues of the alga. It was also shown antitumor activity of water-ethanolic extract F.evanescens on model of human intestinal cancer cells [6].

All of the above and determined the purpose of our work - to assess the possibility and feasibility of using water-ethanolic extract in technology of bakery products.

Water-ethanolic extract F.evanescens  is muddy, oily liquid, dirty-green color with a strong smell of the sea, which we believe can neutralize various fruit fillings. We decided to use water-ethanolic extract as an ingredient to create a filling. In our opinion the jam due to its consistency is the best choice [3].

In the first stage, we screened various types of the chosen basis for a fillings. Currant filling eliminates specific taste, color and smell of the water-ethanolic extract F.evanescens, so it has been chosen by us and for further research [1].

Model samples of fillings examined for microbiological safety criteria, organoleptic and physico-chemical indicators.

Was produced commodity products - fillings, with the addition of water-ethanolic extract F.evanescens and was taken control sample (jam without water-ethanolic extract F.evanescens). Comparative evaluation of these products on organoleptic parameters revealed no significant abnormalities of physicochemical indicators developed by the fillings meets the requirements of GOST R 51934-2002 "Jam. Specifications". According to the research of microbial indicators and safety performance, it was concluded that currant filling with water-ethanolic extract F. evanescens meet the requirements of the Technical Regulations of the Customs Union 021/2011 and is safe.

Thus, the use of water-ethanolic extract F.evanescens in production technology fillings is a promising and economically feasible in the field of waste-free technologies in the production of BAA Fukolam and processing of secondary raw materials.
