With the gradual acceleration of the pace of urban work and life, people's lifestyle and eating habits are mainly "fast", and the intake of fruits and vegetables is obviously insufficient. This long-term unbalanced nutritional intake has led to obesity, illness and other diseases. Therefore, a health food that can be enjoyed in a short time, tastes delicious and has reasonable dietary nutrition has become a necessity for people's daily needs, and the fruit and vegetable powder labeled with "no addition" and "high purity" just meets these needs.

As we all know, the essence of fruit and vegetable powder is still fruit and vegetable. It is only processed by using freeze-drying technology and equipment to process fresh fruits, vegetables or concentrated juice and fruit juice through freeze-drying, heat drying, spray drying and other technologies and related equipment through more than 10 processes, such as pretreatment, vacuum drying, ultraviolet sterilization, packaging and storage.

This process not only retains the taste, fiber, color and nutrition of fruits and vegetables, but also stimulates the bioactive peptides, also known as plant protein peptides, as the main source of nutrients during the separation and purification process.

What are plant protein peptides?

Perhaps many people have heard the concept of peptide and know that it is a substance between protein and amino acid. It is an essential participant in the body to complete various complex physiological activities. It can regulate various physiological activities and biochemical reactions.

Plant protein peptides, as the name suggests, are peptide substances that exist in plants. As a water-soluble protein, plant protein peptide has successfully occupied the high position of "completely absorbed by the human body" with a molecular weight of only 500da. As a highly active peptide, plant protein peptides are easier to be synthesized by artificial chemistry and have extraordinary bioavailability.

Soybean peptide, corn peptide, wheat peptide, mung bean peptide and pea peptide, which we are familiar with, belong to the category of plant peptides.

What is the use of plant protein peptides?

Among the seven nutrients, peptide is the most fundamental substance. Many physiological functions of human body are realized through peptide.

1. Antioxidation

Plant protein peptide is recognized as an oxygen free radical scavenger at home and abroad, which means that it can achieve antioxidant effect, especially a large number of antioxidant peptides can be isolated from beans and nuts.

To put it simply, when our skin is exposed to sunlight, radiation and makeup for a long time, skin cells will undergo oxidation reaction and produce a kind of free radical, which can not only destroy skin tissue, cause dull and dry skin, but also cause aging.

The plant protein peptide directly acts on free radicals to completely eliminate the problems of cell aging and melanin accumulation caused by free radicals.

It is this remarkable anti-aging effect that makes plant protein peptides an indispensable raw material in the field of beauty.

2.  Effect of lowering blood pressure, blood sugar and blood lipid

The reason why plant protein peptide can inhibit blood pressure, blood glucose and blood lipids is that the activity of its internal invertase releases the corresponding function.

In fact, there are many active peptide molecules with different functions in plant protein peptides, such as wheat peptide, which can inhibit the production of angiotensin converting enzyme ACE, so as to inhibit the terminal vasoconstriction and prevent the rise of blood pressure. It can also produce wheat germ protein polypeptide under the hydrolysis of specific trypsin, which can easily realize the effective control of blood glucose concentration.

3. Immunomodulation

Plant protein peptides have been the bane of viruses since ancient times, especially the hero of modern immunity. This is because a few peptide molecules have the ability to stimulate the phagocytosis of macrophages and inhibit the growth of tumor cells.

The "three nine protein peptides" that played an important role in the SARS period originated from this. The selenium containing peptides extracted from selenium rich rice also have good immune regulation ability.

With the health care and pharmacological effects of plant protein peptides becoming more and more clear, the fruit and vegetable powder with plant protein peptides as the main raw material has also benefited.

Although on the surface, fruits and vegetables are rich in vitamins, minerals and fiber, among which antioxidant vitamins can prevent cancer and cancer, fiber can help stimulate gastrointestinal peristalsis, and vitamins can accelerate human absorption

However, in fact, the intrinsic activity of plant protein peptides hidden behind fruits and vegetables can only be stimulated and released when they are hydrolyzed with specific protease. Therefore, the beauty and health care effects of fruit and vegetable powder are all due to the contribution of plant protein peptides.

ShuangYuji R & D process

The in-depth research on the plant peptide industry has also provided important help for the rapid development of fruit and vegetable powder. However, the traditional process of making fruit and vegetable powder mostly adopts the process of first crushing and then drying. However, due to the influence of drying temperature, the nutrients of fruit and vegetable powder have been seriously damaged

In this context, ShuangYuji has upgraded the production process of fruit and vegetable powder. Especially in the drying stage, it has developed four technologies: spray drying, hot air drying, freeze drying and vacuum drying. It carries out classified processing according to the needs and raw material characteristics to ensure that the fruit and vegetable powder has good instant solubility on the basis of maximizing the retention of nutritional components.

When fresh fruits and vegetables are processed into vegetable powder, the extremely low water content reduces the loss caused by decay and also inhibits the activity of microorganisms. After further treatment by the drying process, the residual harmful substances in fruits and vegetables are effectively removed.

It not only has the nutritional value of the original fruits and vegetables, but also can be applied to various fields of food processing. Fruit and vegetable powder will eventually become a shining star in the field of beauty and health care.
