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...

Abstract

The invention discloses a preparing method of protein concentrate of sacha inchi fruits. By using the characteristics that the dissolving rates of the protein of sacha inchi fruits and micromolecule impurities in an ethanol solution and an acid aqueous solution are different, sacha inchi fruit meal is extracted with an ethanol solution, alcohol soluble impurities are separated, precipitation is extracted with acid water, acid water soluble impurities are separated, the precipitation is added with water to regulate the pH to be neutral, and the protein concentrate of sacha inchi fruits can be obtained through high-pressure homogenization and spray drying. The preparing method of the protein concentrate of sacha inchi fruits is low in cost, and the protein concentrate is white in color, free of acerbity, edible, high in yield and protein retention rate and capable of achieving mechanization.

Description

Technical field [0001] The present invention relates to the technical field of vegetable protein processing, and more specifically to a method for manufacturing the concentrated protein of imchifruit. Background technique [0002] Inchi fruit is also known as Inca fruit, South American oil vine, star oil vine, scientific name Plukenetia volubilis linneo, English name Sacha inchi. Inchifruit is a perennial woody vine of Euphorbiaceae. It was originally grown in the tropical rain forests of southern South America. It has been eaten by local indigenous people in the Inca region of South America for thousands of years. In 2006, it was successfully introduced by the Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences. Inchi fruit can be planted that year, and it will bloom and bear fruit throughout the year after it enters the rich production period. It has high yield and is an economical crop. The surface of the young fruit of Inchi fruit is smooth, green, dar...
