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 semen armeniacae amarum with a long quality guarantee period and a preparation method of the semen armeniacae amarum, and belongs to the technical field of primary processing of semen armeniacae amarum. The preparation method comprises the following steps of using the semen armeniacae amarum as raw materials, and peeling, debitterizing and detoxifying the semen armeniacae amarum so as to obtain the embryo of semen armeniacae amarum; then performing microwave drying so as to obtain the dried embryo of semen armeniacae amarum; collecting the seedcoat of semen armeniacae amarum, refrigerating the collected seedcoat of semen armeniacae amarum, crushing the refrigerated seedcoat of semen armeniacae amarum, uniformly mixing the crushed seedcoat of semen armeniacae amarum and debitterizing liquid, and performing enzymolysis and two times of distillation so as to obtain an extract of the seedcoat of semen armeniacae amarum; and then performing decoloration, mixing the extract after the decoloration with the dried embryo of semen armeniacae amarum according to a certain proportion so as to obtain a mixture, and then stir-frying the mixture so as to obtain the semen armeniacae amarum with a natural flavor of the semen armeniacae amarum, high smoothness and tidiness, a high debitterizing rate (98.5-99.8%), significant detoxifying effects (the quantity of cyanide residues is 0.04-0.06mg / kg), a long quality guarantee period (24-36months) and a low cost. The preparation method disclosed by the invention is simple in technology, short in cycle, and high in efficiency, saves energy resources, can realize large-scale production, can realize zero discharge of toxic substances in the technical field of the primary processing of the semen armeniacae amarum, is environment-friendly, and provides a new shortcut for the deeply processing of the semen armeniacae amarum.

Description

technical field [0001] The invention relates to primary processing of bitter almonds, in particular to bitter almonds with long shelf life 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 the ...
