Embodiment 1
[0031] A manufacturing method of Yin Qiguo protein concentrate, its steps are:
[0032] 1. Take 100kg of Indian fruit meal after squeezing and extracting oil, crush it with a stainless steel grinder and sieving through an 80-mesh standard sieve to obtain Indian fruit meal for later use;
[0033] 2. Using No. 6 solvent as the oil extractant, the residual oil in the pressed kiwi fruit meal is extracted by standard leaching method, the oily solvent is separated, and the defatted kiwi fruit meal with a small amount of residual solvent is deoiled after heating After desolventizing, the residual oil content of the defatted printed fruit meal powder is ≦1%, and the residual solvent content is ≦50ppm;
[0034] 3. At room temperature, add 2 times the mass of the 75% ethanol aqueous solution to the defatted dried fruit meal with a volume percentage of 75%. After stirring for 2 hours, use 20% hydrochloric acid with a mass concentration under stirring. Adjust the pH to 2.5 or 2.8 or 3.0, contin...
Embodiment 2
[0039] A manufacturing method of Yin Qiguo protein concentrate, its steps are:
[0040] 1. Take 850 kg of Indian fruit meal after squeezing and extracting oil, crush it with a stainless steel grinder and sieving through a 40-mesh standard sieve to obtain Indian fruit meal for later use;
[0041] 2. Using petroleum ether solvent as the oil extractant, use standard leaching method to extract the residual oil in the pressed kiwi fruit meal, separate the oily solvent, and degrease the defatted fruit meal with a small amount of residual solvent after heating treatment After desolventizing, the residual oil content of the defatted printed fruit meal powder is ≦0.5%, and the residual solvent content is ≦20ppm;
[0042] 3. Add 3 times the mass of the 60% ethanol aqueous solution to the defatted kiwi fruit meal powder. After stirring for 3.0 hours, use 20% hydrochloric acid with a mass concentration to adjust the pH to 3.0 or 3.3 or 3.5, heat the mixture to 30°C and maintain it at 30°C, and ...
Embodiment 3
[0047] A manufacturing method of Yin Qiguo protein concentrate, its steps are:
[0048] 1. Take 100kg of Indian fruit meal after squeezing and extracting oil, crush it with a stainless steel grinder and sieving through a 100-mesh standard sieve to obtain Indian fruit meal for later use;
[0049] 2. Using n-hexane as the oil extractant, the residual oil in the pressed kiwi fruit meal powder is leached by the standard leaching method, the oily solvent is separated, and the degreased fruit kiwi fruit meal powder with a small amount of residual solvent is deoiled after heating After the solvent, the defatted printed fruit meal, the residual oil content of the defatted printed fruit meal ≦1%, and the residual solvent content≦30ppm;
[0050] 3. At room temperature, add 2 times the mass of the 90% ethanol aqueous solution to the defatted dried fruit meal powder. After stirring for 2 hours, use 10% sulfuric acid under stirring conditions. Adjust the pH to 2.0 or 2.3 or 2.5, continue stirrin...
