[Biologically active food supplements as sources of flavonoids, tannins and dietary fibers].

The content of some biologically active substances such as bioflavonoids, tannins and dietary fiber in various type of biologically active additive was analyzed. The results are shown that the content of bioflavonoids ranger from 26.0 to 3970.

[Contents of flavonoids, tannins and fiber in some species of vegetative tea].

[Physical, chemical and biological properties of food modified starches].

Aim of work was to compare the chemical and biological properties of starches modified by adipinic acid acetylation. Starches in question were: native maize starch "Novation 4600"; acetylated adipat di-starch of the cold swelling "Prejeflo CH 20"; acetylated adipat di-starch of the cold swelling "Prejeflo CH 40"; acetylated adipat di-starch of the hot swelling "Clearam CH 2020". The differences between starches were connected with number of cross-cut lacings in the structure, and with abilities to be gelatinized in the cold water.

[Study of qualitative and quantitative of dietary fibre composition in dry breakfasts and food supplements, contains wheaten brain].

Qualitative and quanitative composition of 15 samples of dry breakfasts and 19 variants food supplements, containing wheaten brain, was studied with a help of enzyme method, based on hydrolysis of protein and starch by enzymes, analogous with enzymes of digestive tract homo. It is shown, that the common contents of dietary fibres in samples of dry breakfasts is in limits from 11 up to 39%. Greatest contents IDF is observed in samples of breakfasts with addition of a thistle from 21 up to 35%, and greatest contents SDF with addition (see text for symbol) and beet - 9% and 7% accordingly.
