Problems solved by technology

The mechanical pressing method has long pressing time, low oil yield, high impurity content, poor oil quality, and darker color; the organic solvent extraction method has long extraction time, low efficiency, large solvent consumption, and easy to cause solvent residue in the product and a series of disadvantages; while supercritical fluid extraction has high requirements for equipment, complex process, small equipment volume, high cost, and high energy consumption, so it is not suitable for large-scale industrial continuous production

Embodiment 1

[0023] An implementation example of a method for preparing quinoa seed oil by enzymatic hydrolysis, comprising the following steps:

[0024] (1) Refining: After soaking quinoa seeds in 3 times the amount of drinking water for 2 hours, use a refiner to grind into pulp and collect the slurry; the refiner can be DB-20 produced by Guangzhou Debang Machinery Equipment Co., Ltd. type refiner;

[0025] (2) Adjust the pH value: adjust the pH value of the slurry to 5.5 with 5% hydrochloric acid with a mass concentration;

[0026] (3) Enzymolysis: Take a compound enzyme preparation with a weight of 1.5% of the dry weight of quinoa seeds, dissolve it in drinking water at 45°C that is 3 times the weight of the compound enzyme preparation, and then pour the dissolved compound enzyme preparation into the quinoa seed slurry In the method, enzymolysis was performed in a water bath at a temperature of 55°C for 8 hours; the enzyme preparation was selected from the cellulase produced by Shangha...

Abstract

The invention discloses a method for preparing quinoa seed oil by an enzymolysis method. The method comprises soaking quinoa seeds in drinking water, carrying out grinding to obtain pulp, adjusting a pH value, carrying out enzymolysis through a compound enzyme preparation, carrying out enzyme deactivation treatment and demulsification, carrying out centrifugation and collecting the oil. The quinoa seed oil has the advantages of good quality, simple and safe processes, strong operability and short oil production period.

Description

technical field [0001] The invention belongs to the technical field of oil extraction and processing, in particular to a method for preparing quinoa seed oil by enzymatic hydrolysis. Background technique [0002] Quinoa is a staple food of the ancient civilizations in the Andes region of South America. It is mainly planted in Andean countries such as Peru and Bolivia, and it has also begun to be planted in Tibet, Shanxi, Qinghai and other places in my country. In order to promote the nutritional value of quinoa, the United Nations has declared 2013 as the "International Year of Quinoa". It is sometimes called "pseudo-cereal" because of its grain-like appearance, and sometimes "pseudo-oil" because of its high oil content. [0003] Quinoa has a very delicate taste with a nutty and earthy aroma. Quinoa contains saponins, which are usually mechanically removed before sale or carefully rinsed before cooking to remove the bitter taste. According to the content of saponins, quin...
