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.
