Embodiment 1

[0023] Almond debittering method comprises the following steps:

[0024] a Raw material selection: select almonds with full grains, uniform size, and no moth-eaten or moldy deterioration, remove impurities, and rinse for later use;

[0025] b Soaking: Soak the almonds in water for 1 hour, and the water consumption is 3 times the mass of the almonds;

[0026] c Freezing: Take out the soaked almonds and drain them, then place them in -18°C for quick freezing;

[0027] d Negative pressure soaking: put the frozen almonds into clear water with a temperature of 60°C, vacuumize to -0.07Mpa, keep for 1.5h, the water consumption is 6 times the mass of almonds, keep boiling at low temperature during the period, and keep rotating and stirring, The cyanide in the almonds is removed by vacuuming;

[0028] eHigh-pressure soaking: then put the almonds into normal temperature salt water, pressurize to 0.03Mpa, keep for 1.5h, the amount of salt water is 5 times of the quality of the almonds;...

Abstract

The invention provides a method for debitterizing apricot kernels for noodles. The method includes raw material sorting, soaking, freezing, negative-pressure soaking, high-pressure soaking, drying, and detection. The method for debitterizing the apricot kernels is short in debitterizing time, adopts less water, can keep the apricot kernel flavor and nutrient substances, and has good debitterizing effect.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to a method for debittering almonds. Background technique [0002] Almond is the seed kernel of Rosaceae plant apricot fruit, which is rich in vegetable protein, unsaturated fatty acid, multivitamins and trace elements. . Almonds are divided into sweet almonds and bitter almonds. Almonds produced in southern my country belong to sweet almonds (also known as southern almonds), which taste slightly sweet and delicate, and are mostly used for food. The therapeutic effect of bitter almonds is the same as that of sweet almonds, but because of its strong bitter taste and slight toxicity, not many people eat them, so the price is relatively low. If the bitterness of bitter almonds can be effectively removed and the nutritional flavor of almonds can be maintained, it will make bitter almonds be widely used. [0003] The bitter taste of almonds comes from bitter cyanogenic glycosides: amyg...
