Soy protein powder
Soy protein powder
Soy protein isolate is extracted from soybean through a series of processing steps, and the purified protein is obtained. Soy protein isolate contains eight kinds of essential amino acids, and meat, fish, eggs, milk approximation, belong to the full price of protein. Research shows that: protein is the material basis of life, is one of the three major components of the human body. Lack of protein will directly lead to growth retardation, low immunity, skin relaxation and premature aging.
Product specifications: Protein more than 55% moisture less than 7% fat less than 1% ash content less than 4% of total fiber is less than or equal to 4%
Color: Light yellow or milky white
Particle size: 100 mesh -150 mesh
PH value: 6.3-6.8
With the improvement of people's living standard, people pay more attention to the plant protein. Bean products processing is no longer a traditional tofu products, but toward the development of high protein, multi functional protein products. So the production of soy protein isolate, protein concentrate and tissue protein has attracted more and more attention.
Comparison of soy protein isolate and protein concentrate:
Soy protein isolate is defatted bean sheet after alkali extraction, spray drying processes, such as the white beans in soluble protein extracted from the protein content reached more than 90%. Soy protein isolate is one of the most advanced products in soy protein and has the best functional properties. Protein concentrate is defatted white powder by spray drying with acid leaching method, removal of soluble sugar and preparation.
Soybean protein has the highest protein content, and its nutritional value is only next to the protein, but it is higher than other protein products such as protein. Due to the low cost of soy protein concentrate, functional and protein similar to the separation of protein in the general food products can replace the separation of protein, so it has a broad development prospects of the same as the separation of protein.
Soybean concentrated protein purification equipment separation of protein centrifuges to produce protein concentrate production, in a number of desert ratio, increase the time separation effect is good. The functional properties of the same separation protein can be widely used in meat processing, health food, seasoning and beverage, etc.. But at present, the domestic production of concentrated protein is still very little, and its development and application are still to be further developed.
Product advantage:
1, And fish meal compared: fish meal delivery is restricted and impurity content, quality of instability, pig food absorption rate is low, easy to diarrhea; at the same time the shelf life of fish meal short is not easy storage.
2,Compared with the plasma protein: plasma protein is currently recognized as the feed industry, high quality protein source, but it is undeniable that the price is expensive, while the plasma protein derived from animals.
3, Compared with skim milk powder, skimmed milk powder protein content, low amino acid content, high price of supply limited.
4, Compared with the whey powder: whey protein content is low, supply is not timely and the price is high, the growth rate of piglets after eating slow.
Comparison of the production process of soybean protein isolate and protein concentrate
1,Separation of protein production process
Defatted soy flakes - > alkaline leaching - > soybean residue separation - > acid precipitation, curds and whey separation - > curd washing, secondary milk curd and whey separation, aging - > and sterilization and spray drying.
2,Soybean protein concentrate purification equipment production process:
Defatted soy flour, acid leaching, a curds and whey protein isolate, whey secondary separation, ageing, - > and sterilizing, spray drying
