protein and vitamin herbal tea from the tops of sugar beet
When
growing sugar beets are valuable by-product of its leaves, the output of which
is from 30 to 100% of the crop roots. Nutritionally 5 kg of green leaves
correspond to 1. Units. Leaves contain 15-22% dry matter (1 kg dry matter of
fresh foliage is equal to 1 in. U). Dry matter leaves rich and contains soluble
carbohydrates and 2.5% of protein (2.5 fold greater than the root), ash
elements and vitamins. By the number of feed units and protein sugar beet tops
are not inferior to sown grass. However, it contains a salt of oxalic acid and
feeding the animals in large quantities in fresh or silage may cause a
disruption of calcium metabolism and digestive disorders [1].
It
consists of a relatively large amount of sugar, protein and B vitamins C and A
(carotene). Water in the leaves (tops) contains 78-85 percent solids - 15-22
percent, including ash - 1.3-2.7 percent, crude fiber and nitrogen compounds -
about 2, nitrogen-free extractives - 9-15 percent. Dry matter beet topper
comprises up to 25 percent protein. It concentrated more than half of the
protein nutritional value of the whole plant as a whole and about a quarter -
of energy [2].
At
present, the increased interest in the various plants and herbs, is a natural
source of nutrients for the body. Dried leaves of sugar beet can be positioned
as a high-value protein and vitamin herbal komponent natural resources, slowing
down the aging process. However, infusions and decoctions based on the dried
tops have an unattractive color, smell and taste. Significantly improve the
organoleptic characteristics and thus to preserve the beneficial properties
allows special processing technology leaves - fermentation, combined with the
processing of ultrashort electrical pulses. The result is the formation of
peculiar taste and flavor of beet herbal tea, approximate to that of a
traditional black tea. The composition of the herbal tea is presented in Table
1.

Sufficiently
high (14.56%) level within herbal tea
fiber - fiber and pectin and BEV (59.56%), which mainly include sugar,
starch and other soluble compounds are used by the body for energy needs.
Pectins have the property to swell and excrete harmful substances including
heavy metals and cholesterol, which in turn improves the gastrointestinal
tract. Therefore, we can say that this drink gives strength, vitality, helps
cleanse the body and healing. As part of the protein fraction of herbal tea
based fermented beet tops contains 16 amino acids (Table 2), seven of which are
irreplaceable. However, the assessment of the amino acid soon revealed that,
like all vegetable proteins, protein beet tops is not a full-fledged.

It
is particularly scarce are sulfur-containing amino acids methionine and cystine
and lysine, so herbal tea should not be marketed as a source of protein.
Therefore, beet herbal tea should be considered as the basis for the creation
of various compositions of herbal teas that promote vitality and immunity.
