Problems solved by technology

Chickpeas have no allergens and are favored by developed countries such as Europe and the United States. Because chickpeas contain less oil, their processing is generally simple grinding or alkali-soluble acid precipitation to extract protein, and the process of alkali-soluble acid precipitation to extract protein Chemical reagents such as acid-base solutions that are harmful to food will be used, and a large amount of beneficial starch and cellulose will be lost in the extracted protein powder; Grease will react with oxygen and moisture in the air to cause oxidation, decomposition, rancidity and other reactions, which seriously affects the flavor and quality of its protein products, and directly affects the shelf life of its powder products

Embodiment 1

[0049] Break the peeled chickpeas into 4 petals, soften again, the softening temperature is 65°C, press the embryo again, the thickness of the embryo sheet is 0.26mm, and transport the embryo sheet to the extraction tank by air; when the material reaches 70% of the volume of the extraction tank When measuring, close the feed valve, turn on the vacuum pump, and discharge the air in the extraction tank. When the gauge pressure is -0.08MPa, close the vacuum pump and the corresponding valve, use liquefied butane as the extraction aid, and open the aid inlet valve and the aid Pump, inject the second extraction liquid from the last extraction tank as the first extraction aid for the material, material: liquid = 1:1; jacket heating, the temperature of the extraction tank is kept at 45 ° C, and the extraction pressure is maintained at 0.6 MPa , soak for 40min, open the drain valve, discharge the first extraction to the concentration tank; open the auxiliary agent inlet valve and auxili...

Embodiment 2

[0051] The chickpeas are cleaned of impurities, broken into 6 petals, and then softened. The softening temperature is 60°C, and the embryos are pressed again. The thickness of the embryos is 0.29mm, and the embryos are transported to the extraction tank by air; When measuring, close the feed valve, open the vacuum pump, and discharge the air in the extraction tank. When the gauge pressure is -0.085MPa, close the vacuum pump and the corresponding valve, use liquefied propane as the auxiliary agent, and open the auxiliary agent inlet valve and auxiliary agent pump. The second extraction solution injected into the previous extraction tank is used as the first extraction aid for the material, material: liquid = 1:0.8; the jacket is heated, the temperature of the extraction tank is maintained at 42 °C, and the extraction pressure is maintained at 1.6 MPa. 35min, open the drain valve, discharge the first extract to the concentration tank; open the auxiliary agent inlet valve and auxi...

Embodiment 3

[0053] Peeled chickpeas, broken into 6 petals, softened again, the softening temperature is 80°C, and then pressed embryos, the thickness of the embryos is 0.32mm, and the embryos are transported to the extraction tank by air; when the material reaches 75% of the volume of the extraction tank When measuring, close the feed valve, open the vacuum pump, and discharge the air in the extraction tank. When the gauge pressure is -0.09MPa, close the vacuum pump and the corresponding valve, use liquefied 134a as the auxiliary agent, and open the auxiliary agent inlet valve and auxiliary agent pump.

Abstract

The invention discloses a processing method of chickpea defatted powder. The processing method comprises the following steps: S1, performing crushing; S2,performing softening; S3, briquetting; S4, performing feeding; S5, performing dissolving; S6, performing extracting; S7, recovering an extraction agent; S8, desolventizing the meal; and S9, performing micronizing to obtain chickpea defatted powder. A processing device adopted by the processing method comprises pretreatment equipment, low-temperature extraction equipment and micro powder equipment, the pretreatment equipment comprises a crusher, a softening pot and a briquetting press, and the low-temperature extraction equipment comprises an extraction tank, a concentration tank, a solvent pump, a condenser, a solvent turnover tank, a vacuum pump and a compressor; and the micronizing equipment comprises a micronizing machine, a material collector, a dust remover and a fan. The chickpea powder prepared by the device and the method disclosed by the invention is not gelatinized in starch, not denatured in protein, low in oil content and long in shelf life.

Description

technical field [0001] The invention specifically relates to a method for processing chickpea defatted powder, which belongs to the technical field of grain and oil deep processing. Background technique [0002] Chickpea is the second most consumed legume in the world. It is a high-quality plant protein resource with complete nutrients and rich content. Among them, carbohydrates and protein account for about 80% of the dry weight of the grain, and fat accounts for about 5%. Compared with other beans, it has the advantage of lower fat content. In addition, it is also rich in dietary fiber, trace elements and vitamins. The slow-digesting starch and resistant starch in chickpea starch are high, and the glycemic index GI is low, which meets the classification standard of low GI starch. Long-term consumption of this kind of starch is beneficial to human health and can reduce blood sugar. Chickpea protein contains a complete set of 8 kinds of amino acids necessary for the human ...
