Safety of vegetable raw materials used in the production of flour products in order to increase their mineral value

Abstract

Wheat high-grade flour used in the technology of flour products is poor in respect of certain minerals (iron, calcium, etc.), so their mineral value is increased by using non-traditional raw materials for production, in particular flax flour and red mountain ash fruits, in the recipe of bread, muffins, muffins, gingerbread, cookies, etc. the Purpose of research is to study the mineral composition of wheat, flax and mountain ash raw materials in a comparative aspect to establish its safety and effectiveness usage. The objects of tests were: wheat flour baking of the first grade (JSC “Shadrinsky combine of bread products”, Kurgan region, Shadrinsk), flax flour (LLC NPO “Compass of health”, Novosibirsk), red mountain ash fruit (LLC “Staroslav”, Novosibirsk region, Berdsk). Physical and chemical parameters and mineral composition of raw materials were studied. The superiority of Flaxseed flour over wheat in the amount of potassium (33.3 times more), calcium (27.2 times more), magnesium (16.2 times more), iron (8.5 times more), copper (6.1 times more), phosphorus and zinc (4.8-4.9 times more), and manganese (4.3 times more); Rowan fruit - by the content of manganese (12.5 times) and iron (3.9 times). The upper limit was exceeded in both types of flour by the amount of lead, which is a violation of the regulated requirements of TR CU 021/2011. The effectiveness of the use of red Rowan fruit in replacing wheat flour in order to increase the level of dietary fiber, manganese and iron in ready-made flour products was shown.
