specific Embodiment approach 1

[0054] Specific implementation mode one, see figure 1 The process roadmap for the synchronous extraction of sesame oil and sesame polypeptide powder by the aqueous enzymatic method illustrates this embodiment. The method for synchronously extracting sesame oil and sesame polypeptide powder by the aqueous enzymatic method described in this embodiment includes the following steps:

[0055] (1) Peeling white sesame seeds are subjected to wall-breaking treatment to obtain sesame powder.

[0056] (2) Mix sesame powder with water and perform ultrasonic treatment to obtain sesame turbid liquid.

[0057] (3) The sesame turbid liquid obtained in step (2) is subjected to step-by-step enzymolysis, and then the sesame turbid liquid after enzymolysis is centrifuged to obtain 1 st Free oils, emulsions, hydrolysates and residues, of which 1 st The free oil is sesame oil.

[0058] (4) the emulsion obtained in step (3) is demulsified and centrifuged to obtain 2 nd Free oil and emulsion, of...

specific Embodiment approach 2

[0060] Specific embodiment two, this embodiment is a further limitation to specific embodiment one, the method for synchronously extracting sesame oil and sesame polypeptide powder by the aqueous enzymatic method, the sesame powder described in step (2): water=(1:4 )~(1:8)(w / v).

specific Embodiment approach 3

Abstract

The invention relates to a method for synchronously extracting sesame oil and sesame polypeptide powder through an aqueous enzymatic method and belongs to the technical field of biological processing of grain and oil. The invention aims to solve the problems of low extracting efficiency of sesame oil, protein mutability after oil extraction, low use ratio and accordingly caused high energy consumption and cost at present. The invention adopts a wall breaking-ultrasonic-stepping enzymolysis combined extracting technology for synchronously extracting sesame oil and sesame polypeptide powder. The method comprises the following steps: performing wall-breaking and ultrasonic treatment on peeled white sesame seed in turn; performing stepping enzymolysis on the acquired sesame muddy solution, thereby acquiring 1st free oil, emulsion, hydrolysate and residue; breaking the emulsion, thereby acquiring 2nd free oil; and performing enzymolysis, ultrafiltration, vacuum concentration and spray drying on the hydrolysate, thereby acquiring polypeptide powder. According to the invention, the extraction temperature is low, the protein is difficult to denature, the oil extraction rate is high, the two products of high-quality green sesame oil and sesame polypeptide powder can be synchronously acquired and the prepared polypeptide can be used as the raw material of healthcare food and medicinal product and has obvious economical, environment and social benefits.

Description

technical field [0001] The invention belongs to the technical field of grain and oil biological processing, and in particular relates to a method for synchronously extracting sesame oil and sesame polypeptide powder by using an aqueous enzymatic method. Background technique [0002] my country is one of the major planting and producing countries of sesame, its output ranks first in the world, and occupies a very important position in people's daily life. Sesame is known as the "Queen" of oil crops. It is a large variety of oil crops among small varieties of oil crops. It has extremely high nutritional value, health care function and medicinal value. Sesame oil is one of the three best edible oils announced by WHO. It not only has high nutritional value, but also has medicinal value. ". It is rich in oleic acid (36.9%-50.5%) and linoleic acid (36.9%-49.1%), which are very beneficial for lowering cholesterol, softening blood vessels, and preventing diseases caused by vascula...
