Problems solved by technology

However, the dry crushing has a large shear force and high temperature, resulting in a large loss of nutrients and biologically active substances in almond oil.
[0009] Chinese patent CN102796613B discloses a method of hydroenzymatically extracting soybean oil and microbial demulsification, which belongs to vegetable oil extraction technology. The method includes the following steps: (1) Extrusion and puffing are used to obtain puffed material after soybean crushing, and the puffed material is mixed with Mix with water to obtain a mixed solution, add alkaline protease to the mixed solution for enzymolysis, and centrifuge after enzymolysis to obtain free oil, emulsion, hydrolyzate and residue; Inorganic salt liquid medium is fermented to obtain mixed demulsifying bacteria full culture solution; (3) the emulsion obtained in step 1) is adjusted to neutral pH, fully mixed with mixed demulsifying bacteria full culture solution, and left to stand for constant temperature demulsification, Soybean oil is obtained by centrifugation after demulsification; although the demulsification rate is high, the oil after demulsification is centrifuged and mixed with demulsifiers and water, and the emulsion oil, demulsifiers and water cannot be completely separated, affecting Food Safety and Stability of Oils and Fats
The bitter almond oil extraction rate that above-mentioned method makes is lower

Abstract

The invention discloses environment-friendly semen armeniacae amarae oil and a method for extracting the same. The environment-friendly semen armeniacae amarae oil and the method have the advantages that the semen armeniacae amarae oil is made of semen armeniacae amarae which is a raw material, low-temperature biological processing technologies are adopted in whole procedures, accordingly, loss of thermo-sensitive nutrient substances such as protein, higher fatty acid and vitamins in the semen armeniacae amarae can be effectively prevented, first free oil, emulsion, hydrolysate and semen armeniacae amarae residues can be obtained by means of microwave irradiation enzyme deactivation, frozen-breaking, enzymatic hydrolysis and vacuum centrifugation, the emulsion is subjected to biological demulsification and then is subjected to vacuum centrifugation again to obtain second free oil, and the first free oil and the second free oil are combined with each other to obtain the semen armeniacae amarae oil which is high in oil extraction rate (93-97%), nutrient and active substance content and food safety (cyanide residual quantities are lower than 0.08 mg / kg) and long in shelf life; by the aid of the method, the quality of products can be improved, the yield of the products can be increased, the varieties, the yields and added value of byproducts obtained after the oil is extracted can be increased, the oil extraction cost further can be reduced, emission of 'waste gas, waste water and industrial residues' can be completely eradicated, and accordingly environments can be protected.

Description

technical field [0001] The invention relates to the technical field of vegetable oil extraction, in particular to an environment-friendly bitter almond oil and an extraction method thereof. Background technique [0002] Almond is the seed of apricot, a plant of the genus Prunus in the Rosaceae family. It is also called apricot kernel, apricot, muluozi, bitter almond, apricot plum kernel, sweet plum, etc. It is flat heart-shaped, with a yellowish-brown to dark brown surface, thin seed coat, and a Creamy white, oily. In China, it is mainly distributed in Hebei, Liaoning, Northeast China, North China and Gansu. Almonds are divided into two categories, sweet almonds and bitter almonds. Sweet almonds are sweet, do not contain or only contain 0.1% amygdalin, and have a fat content of 45% to 67%. Bitter almonds are bitter and contain 2% to 4% amygdalin. Almond oil is the essence of almonds. The content of oleic acid and linoleic acid in bitter almond oil reaches more than 90%, ...
