Problems solved by technology

However, Rana roe oil contains a variety of unsaturated fatty acids. When exposed to the air for a long time, certain components such as unsaturated fatty acids are easily oxidized and lose their activity and active ingredients. Taking Rana ova oil directly will result in substandard dosage. Disadvantages such as inconvenient use

Abstract

The invention discloses a method for assisting in extracting wood frog spawn oil by an ultrasonic method and a preparation method of wood frog spawn oil microcapsules, and relates to the technical field of a microencapsulation technique and food processing. The method for assisting in extracting the wood frog spawn oil by the ultrasonic method comprises the main step of extracting the wood frog spawn oil by using ethanol as an extraction solvent under the condition that the feed liquid ratio is 1:7 to 1:11, the soaking time is 3-5h, the ultrasonic time is 20-50min, and the vibration frequency is 10-30KHz. The extraction rate of the wood frog spawn oil by the method can achieve 20% or above. The prepared wood frog spawn oil is entrapped with whey protein and beta-cyclodextrin, and spray drying is performed, so that the wood frog spawn oil microcapsules are obtained. The wood frog spawn oil microcapsules not only are good in solubility, rich in nutrition and convenient to eat, the stability of products is also improved, and the wood frog spawn oil microcapsules are convenient to transport and store, and have a favorable market prospect.

Description

technical field [0001] The invention relates to an ultrasonic-assisted extraction of wood frog egg oil and a preparation method thereof for microencapsulation, and relates to an ultrasonic method for extracting wood frog egg oil and health care medicines. Background technique [0002] Chinese forest frog (Hashi frog) is a precious tonic and nourishing Chinese herbal medicine specially produced in the tail veins of Changbai Mountain in my country. The earliest record is found in "New Ginseng for Decoction Pieces". function of the kidneys. Rana egg oil unsaturated fatty acids account for about 70%, mainly hexadecenoic acid, linoleic acid, oleic acid, EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid) and so on. In 2015, Lu Jing proved that the polyunsaturated fatty acid of Rana egg oil is a non-toxic substance, has no acute toxicity and mutagenicity, and has good safety. Rana egg oil can significantly reduce the content of serum cholesterol in hyperlipidemia, increase th...
