Problems solved by technology

But contain ethanol and hydrocyanic acid in the debittering liquid of above-mentioned method simultaneously, both are all very soluble in water, are difficult for separation, cause separation process cost to raise, pollute environment again after discharge, and hyperosmotic ethanol solution (80%) will The surface of bitter almonds is rough and not smooth, which affects the appearance and natural flavor of the product. At the same time, the debittering rate is not high, the highest is about 95%.
[0009] In summary, the production and processing of bitter almond products in the above-mentioned disclosed patents and technical documents is limited to the development of a single product, while discarding other by-products, especially the precursor substance amygdalin, which is the precursor of benzaldehyde, as a toxic substance, which not only caused A large amount of waste of resources also pollutes the environment, and simultaneously loses the natural flavor of bitter almonds. Therefore, it is still a challenge for those skilled in the art to seek a kind of bitter almonds with natural flavor of bitter almonds, high debittering rate, long shelf life and low cost. relentless pursuit

Abstract

The invention discloses low-yanide semen armeniacae amarum and a preparation method thereof and belongs to the technical field of primary processing of semen armeniacae amarum. The preparation method comprises the following steps: semen armeniacae amarum is adopted as the raw material and subjected to peeling, debittering and detoxification to obtain almond carpel; the almond carpel is subjected to microwave drying to obtain dry almond carpel; semen armeniacae amarum skin is collected, frozen and crushed, and the crushed semen armeniacae amarum skin is uniformly mixed with a debittering liquid; the mixture is subjected to enzymolysis and twice distillation to obtain a semen armeniacae amarum skin extract; the semen armeniacae amarum skin extract is decolored and then mixed with the dry almond carpel at a certain proportion; the obtained mixture is stir-fried to obtain the semen armeniacae amarum which has the natural flavor of semen armeniacae amarum, is smooth and tidy, high in debittering ratio (98.5-99.8 percent), remarkable in detoxification effect (the cyanide residual quantity is 0.04-0.06 mg / kg) and long in guarantee period (24-36 months). The preparation method is simple in process, short in period, high in efficiency and energy-saving, can realize mass production, achieves the purpose of zero emission of toxic substances in the technical field of primary processing of semen armeniacae amarum, is environmental-friendly and explores a novel shortcut for deep processing of semen armeniacae amarum.

Description

technical field [0001] The invention relates to initial processing of bitter almonds, in particular to bitter almonds with low cyanide content and a preparation method thereof. Background technique [0002] Bitter almond (Semenarmeniacaeamarum) is the dry mature seed kernel of Prunusarmeniaca L.var.ansuMaxim., Siberian apricot Prunussibirica L., Northeast apricot Prunusmandshurica (Maxim.) Koehne or apricot Prunusarmeniaca L. of the Rosaceae plant. It also occupies an important position in the international nut market. Bitter almond is rich in nutrition, and its main components include amygdalin (2%-7%), bitter almond oil (45%), almond protein (25%) and carbohydrates (3%); in addition, it also contains a variety of trace elements ( Such as potassium, calcium, iron, etc.) and rich vitamin E; these determine that bitter almonds have extremely high edible and medicinal value, and are good raw materials for developing functional foods. [0003] Amygdalin (Amygdalin) is one of ...
