Embodiment 1

[0040] A preparation method of oily bean oil and oily bean powder, the steps are:

[0041] (1) Crushing, sifting and soaking and refining: Take 25.6kg of peeled oily bean powder crushed by a stainless steel grinder and sieved through a 100-mesh standard sieve; add water 5 times its mass to the peeled oily soybean powder to adjust the mixture Raise the material temperature to 40° C., stir for 1 hour to make the peeled oily bean powder fully absorb water and expand, and use a refiner to grind to obtain a mixed material of oily bean milk and residue. The stirring speed of this step is controlled to be 140 rpm.

[0042] (2) Weak base extraction and enzymatic protein hydrolysis: under the condition of constant stirring, adjust the temperature of the mixed material of Yousha and soybean milk dregs obtained in step (1) to 55°C and maintain it at 55°C, and use a potassium hydroxide solution with a concentration of 10% by mass Adjust the pH to 9.4 or 9.5 or 9.6, and continue stirring ...

Embodiment 2

[0048] A preparation method of oily bean oil and oily bean powder, the steps are:

[0049](1) Crushing, sieving and soaking and refining: Take 595kg of peeled oily bean powder crushed by a stainless steel grinder and sieved through a 120-mesh standard sieve; add 5.5 times its mass of water to the peeled oily soybean powder, and stir for 2 hours The dehulled oily bean powder is fully swollen by water absorption, and is refined with a refiner to obtain a mixed material of oily soybean milk and residue. The stirring speed of this step is controlled to be 135 rpm.

[0050] (2) Weak base extraction and enzymatic protein hydrolysis: under the condition of constant stirring, adjust the temperature of the mixed material of Yousha and soybean milk dregs obtained in step (1) to 50°C and maintain it at 50°C, and use 10% by mass concentration of sodium hydroxide solution Adjust the pH to 9.9 or 10.0 or 10.1, and continue stirring for 2.5 hours to dissolve protein, pectin and other polysa...

Embodiment 3

[0056] A preparation method of oily bean oil and oily bean powder, the steps are:

[0057] (1) Crushing, sieving and soaking and refining: Take 1254kg of peeled oily bean powder crushed by a stainless steel pulverizer and sieved through a 100-mesh standard sieve; add water 6 times its mass to the peeled oily soybean powder to adjust the mixed material Temperature to 25°C, stirring for 3 hours to make the peeled oily bean powder fully absorb water and swell, and use a refiner to grind to obtain a mixed material of oily bean milk and residue. The stirring speed of this step is controlled to be 125 rpm.

[0058] (2) Weak base extraction and enzymatic protein hydrolysis: under the condition of constant stirring, adjust the temperature of the mixed material of Yousha and soybean milk dregs obtained in step (1) to 50°C and maintain it at 50°C, and use a potassium hydroxide solution with a concentration of 10% by mass Regulate pH to be 9.4 or 9.5 or 9.6, continue stirring for 3 hour...

Abstract

The invention discloses a production method of cyperus esculentus oil and cyperus esculentus flour. Water-soluble characteristics of water-soluble components of cyperus esculentus and properties that starch can form starch milk dispersing in water, protein is soluble in water under alkaline conditions and can be enzymed and the cyperus esculentus oil exists in cells and can break through walls to be released are utilized, the cyperus esculentus is smashed and soaked with water prior to being ground into thick liquid, protein, pectin and cellulose are sequentially enzymed to break through the walls to release the oil, an oil-water mixture is obtained after mixed materials are separated through pulp residues, and the oil-water mixture is subjected to oil-water separation to obtain cyperus esculentus crude oil and cyperus esculentus extract; the cyperus esculentus crude oil is dried and filtered to obtain the cyperus esculentus oil; the cyperus esculentus extract is subjected to heating and gelatinizing into starch, homogenizing, concentrating and spray drying to obtain the cyperus esculentus flour. The method is easy to implement, convenient in operation, low in cost, free from organic solvents, free from refining of oil, high in utilization rate of raw materials, sufficient in extraction of active ingredients and nutrient substances, good in solubility property, remarkable in healthcare function, good in taste and mechanized.

Description

technical field [0001] The invention relates to the technical field of oily bean processing, and more specifically relates to a preparation method of oily bean oil and oily bean powder. Background technique [0002] Sativus Baeck (Cyperus esculentus L.Var. Sativus Baeck), also known as tiger nuts, ginseng beans, tiger beans, iron water chestnuts, underground chestnuts and underground walnuts, belongs to Cyperaceae (Cyperaceae). The herb is one of the most nutritious nuts in tropical to temperate regions. Its origin is Africa and countries along the Mediterranean Sea, and it has a long history of planting. The oily bean is very adaptable. Our country introduced the cultivation of the oily bean from Bulgaria in 1960, and it was successfully introduced and cultivated in Xinjiang in 1964. At present, it is cultivated in Heilongjiang, Beijing, Hebei, Henan, Hubei, Hunan, Shaanxi, Shanxi and Shandong. , Sichuan and other provinces and cities have oily bean planting. [0003] You...
