Soybean
Peptide
Soybean
multi-functional peptide is derived from soybean by zymolysis
process. It is a mixture of low molecular weight (average 1000)
peptides, which are composed of 3-6 amino acids. Soybean
multi-functional peptide is highly water soluble, and has a high
and balanced amino acid content. It is easily digested and
absorbed by the body. Soybean multi-functional peptide can also be
used as a natural health food (medicine) source, because it can
adjust autonomic nerve and activate cell immunity.
A.
Features
and benefits
1.
High
nutrition, excellent digestibility
Of
all vegetable proteins, only the soy protein provides 2-5 year old
children with all the essential amino acids specified by FAO/WHO/UNU
in 1985. Amino acid composition of soybean peptide is almost the
same as that of soy protein. Those babies allergic to milk protein
can use it as a milk substitute.
Recent
metabolic studies have shown that dietary proteins are mostly
hydrolyzed into peptides by digestive enzyme in the stomach and
intestine and then are digested and absorbed by the intestine in
the form of peptides. Labeled isotope experiments in vivo
show that the soybean peptide has higher digestibility than milk
protein and general amino acids do. Clinically, soybean peptide
can be used as nutrition supplement for dyspepsia babies and
seniors, convalescents after surgeries (especially alimentary
tract surgeries), people with strain of lumbar muscles, dyspepsia
persons requiring a large amount of proteins, and people
antigenically allergic to proteins. It can help them return to
balanced nutrition status sooner than injected amino acids.
2.
Glucose
reduction
Soybean
peptide is an effective ingredient of α-glucosidase
inhibitor. By slowing down the digestion of sucrose and
starch,
and preventing glucose level from rapidly rising, it can lower the
glucose level.
3. Blood pressure and cholesterol reduction
Soybean
peptide inhibits angiotensin inverting enzyme activity, so it can
prevent peripheral blood vessel from contracting. Therefore, it
can help hypertensive lower their blood pressure and has no
effects on normal people. It can also reduce harmful LDL-cholesterol
level in serum, but it does not decrease healthy HDL-cholesterol
level. The more important is that soybean peptide can prevent
cholesterol from rising after normal people take meat, eggs, and
animal viscera with high cholesterol content. (The mechanism is
unclear. The reason might be that soybean peptide can combine with
cholesterol to prevent cholesterol absorption.)
4.
Lipid
metabolism enhancement, glucose reduction, and weight loss
Animal
experiments in Japan showed after rats were fed with soybean
peptide, the activity of heat generating fat BAT was stimulated.
The more soybean peptide is fed, the higher activity is. It was
found that obese children lost weight by having soybean peptide,
because soybean peptide can decrease subcutaneous fat deposition,
and increase fat burning and basal metabolism. Therefore, it is a
safe and effective weight loss food (medicine) for obese children.
With another benefit of glucose reduction, it can be taken for a
long time to effectively control weight.
5.
Yeast
starter, gel softner, moisture retention agent for baked foods,
and protein vesicant in food industry
Soybean
peptide can promote microorganism (Bifidobucterium) growth,
stimulate metabolism, proliferate lactobacillus and fungi, and
increase CO2 production of bread yeasts. Due to its
good water absorption and moisture retention, soybean peptide can
be used as an addictive during bread and cake baking to avoid
dryness and extend their valid storage time. Soybean peptide has
good foamability. Studies show that its foamability is as 4 times
high as general proteins.
6.
Health
food addictive for seniors
Due
to illness and senescence, seniors can hardly take enough protein.
Since soybean peptide has excellent digestibility, it is a protein
supplement for the old and weak.
7.
New
fermentation foods, intensifying agent and alcohol removing agent
for fermentation beverage
Soybean
peptide can promote microorganism growth and metabolism, so it can
be used in yogurt, cheese, vinegar, bread and soy sauce production
to increase production efficiency and to improve the stability,
nutrition, and flavor of products. Generally, protein cannot be
dissolved in acid beverages. However, soybean peptide is easy to
be dissolved in acid beverages and the solubility is not affected
by PH. Soybean peptide is able to increase the concentrations of
alanine and leucine in the blood to produce stable NAD, which can
facilitate alcohol metabolism and then decrease alcohol
concentration in the body. Therefore, soybean peptide has a
benefit of alcohol removing and liver protection. In addition,
athletes’ strength is proportional to the muscle mass. The more
exercise, the more energy (protein and amino acid) is needed.
Soybean peptide has a lower molecular weight. It is much easier to
be digested than proteins and amino acid. It can also expedite the
lipid metabolism process of transferring fat to energy so as to
provide athletes with energy and to help them recover from
fatigue.
8.
Other
benefits
Due
to its good moisture absorption and retention, soybean peptide can
be used as a substitute for collagen protein peptides and milk
protein peptides in cosmetics. The benefits are effective, safe,
nontoxic, and skin-protective.
