Application of Potato Protein Powder

Potato protein is a superior plant protein with high nutritional value, rich in lysine, methionine, threonine, tryptophan, and other nutrients. In the 1970s and 1980s, foreign countries began to develop and utilize potato protein, which is now known as the "nutritional gold".
The protein content in a potato is about 2.3%. Although the protein content in potato tubers is not very high, research on potato protein is of great significance from a food perspective as potatoes are an important staple food worldwide and a source of high-quality protein.

Potato extract is rich in protein, crude fiber, and carbohydrates, which can provide the necessary nutrients for the human body. Potato protein contains a large amount of mucin protein, which is a mixture of multiple glycoproteins that can prevent fat deposition in the cardiovascular system, maintain arterial elasticity, prevent premature arteriosclerosis, and also prevent atrophy of liver and kidney connective tissue, maintaining lubrication in the respiratory and digestive tracts. Potato protein, like sweet potato protein, can prevent and treat collagen disease. In addition, potato protein is also a very beneficial health food for middle-aged and elderly people, with important health and physiological functions.
In China, potato protein is a by-product of the potato starch industry, which is a powdered product obtained from the juice water processed from potato starch through processes such as pH adjustment, heating flocculation, dehydration, and drying. According to estimates, a factory that processes 10000 tons of starch annually can extract over 1000 tons of protein powder annually.
As a protein with high nutritional value and rich in various essential amino acids for the human body. The energy and nutritional value of potato protein are significantly better than soybean meal and corn protein. Moreover, potato protein is currently a high-quality and inexpensive natural raw material in China, with broad development prospects.
Currently, there are three main areas of application for potato protein powder in China:
01 Applied to animal feed
Potato protein can be used as an additive to prepare feed, which can increase the protein content in the feed and significantly improve the utilization rate of the feed, thereby reducing feeding costs.
Potato protein powder not only contains abundant protein, but its amino acid composition is quite balanced, comparable to skim milk powder and fish meal. Potato protein powder contains 18.84 MJ/kg of digestible energy, 74.08% of digestible crude protein, and 76.87% of protein biological potency, all significantly higher than soybean meal.
In addition, potato protein powder has high biological nutritional value. Due to its high protein content and natural balance of amino acids in the protein, which is superior to other plant proteins, coupled with its high amino acid content, potato protein is particularly suitable for use as feed for animal cubs; Practice has proven that potato protein, when used as a protein source in adult animal feed, also has good effects, even better than other proteins such as fish meal and soy protein.
In recent years, potato protein powder has been used as an additive in various animal feed such as cattle feed, poultry feed, pet feed, fish feed, etc.
02 Applied in the field of health food
The lysine content in potato protein powder is much higher than that of various proteins, and the nutrition of potato protein is only slightly inferior to egg protein. The lysine content is as high as 93mg/100g, and the tryptophan content is also 32mg/100g.
Potato protein powder contains rich polysaccharide protein bodies, commonly known as mucoproteins, which can prevent fat deposition in the cardiovascular system, maintain the elasticity of arteries and vessels, prevent the premature occurrence of arterial atherosclerosis, prevent the atrophy of connective tissue in the liver and kidney, and maintain the lubrication of respiratory and digestive tracts. Therefore, potato protein is a highly valuable health food for middle-aged and elderly people, and has important health physiological functions.
In addition, potato protein powder is a pure protein concentrate with multiple balanced amino acid components and high nutritional value, making it a highly potential health food. Potato protein powder is rich in protein, crude fiber, and carbohydrates, which can provide certain nutritional elements for humans.
Potato protein also has the effects of enhancing intestinal function, facilitating fecal excretion, reducing blood cholesterol, adjusting blood sugar, controlling weight and weight loss, and preventing colon cancer. I believe that in the near future, through the foodification upgrade of potato protein extraction production technology, the produced potato protein will be recognized as a new health food by people.
