Problems solved by technology

Among them, the physical method is mainly to improve the pressing process of peanut oil to prevent the loss of resveratrol during the pressing process, so as to achieve the purpose of peanut oil containing higher resveratrol; because resveratrol is insoluble under a single physical condition Therefore, there is no existing technology of using resveratrol for physical solubilization; the chemical method mainly uses direct addition of active ingredients, enzymatic esterification to increase the solubility of resveratrol in oil, or resveratrol Alcohol is dissolved in alcohol and then added to increase its content in edible oil; these methods have various disadvantages, for example, the equipment needed for process improvement is very expensive, and it is possible to make resveratrol on the basis of destroying resveratrol Alcohol reacts with oxygen in the air to generate new harmful substances; solvent solubilization method will cause problems such as reagent residue in the product

Abstract

The invention discloses a composite physical solubilization method of resveratrol in peanut oil. The composite physical solubilization method comprises the steps of mixing the peanut oil with the resveratrol in the way that 150-200mg of the resveratrol is added to every 1kg of the peanut oil to obtain a mixture, dispersing the obtained mixture, charging nitrogen gas, performing ultrasonic treatment under the environment that temperature is 48-52 DEG C, performing vibration under the environment of 35-43 DEG C, and finally performing stirring under the environment of 40-60 DEG C. According to the composite physical solubilization method disclosed by the invention, according to specific step sequence, various physical methods are compounded, so that the problem of low solubility and solubilization rate of the resveratrol in the peanut oil by an original physical method is solved, the solubility of the resveratrol in the peanut oil is greatly improved, the method is simple, the effects are good, equipment used in the technique is cheap, and the composite physical solubilization method is suitable for industrial production; and in addition, the problem that hazardous substances are generated is also solved, and the problem of solvent remaining in products is effectively solved.

Description

technical field [0001] The invention relates to the technical field of solubilization of resveratrol. More specifically, the present invention relates to a method for complex physical solubilization of resveratrol in peanut oil. Background technique [0002] Resveratrol is a natural polyphenol with strong biological activity. It has important physiological functions such as anti-tumor, anti-oxidation, and cardiovascular and cerebrovascular protection. anti-aging substances". Peanut is one of the few plants rich in resveratrol, and its content is abundant in peanut rhizomes and red coats, especially the content in roots reaches 908 times that of grapes. However, resveratrol is insoluble in oil and unstable to light and heat, which greatly limits the application of resveratrol in edible oil. The content of resveratrol in peanut oil prepared by peanut processing is also extremely low, only 0-0.93mg / kg. [0003] At present, the methods for preparing edible oil rich in resver...
