Production method of rana japonica oil

Abstract

The invention discloses a production method of rana japonica oil. The production method comprises the steps of cleaning, finishing, low-temperature curing, preliminary drying, oil stripping, microwavedrying, crushing, packaging, etc. The rana japonica oil is cured while the rana japonica is steamed and cured at low temperature, thereby avoiding loss of nutrient substances caused by high-temperature cooking in the eating process, and achieving the ready-to-eat effect. Moreover, multi-stage drying combines with air drying and microwave drying in the drying process. The drying time and temperature in all steps are controlled in the multi-stage drying process, thereby improving drying efficiency, and the drying temperature is strictly controlled to prevent nutrient substances from being damaged at high temperature. Through the process of drying, rehydrating and drying again, the oil stripping process in later stage is also simplified. Finally, microwave vacuum drying is adopted. In the microwave vacuum drying, water migration and diffusion are promoted through concentration difference. Steam and liquid are driven to be directly discharged through pressure and temperature difference. The production method of rana japonica oil achieves fast drying, remains original flavor and nutritional ingredients of the product, and ensures that the rana japonica oil has high dryness and easier storage.

Description

technical field [0001] The invention relates to the technical field of preparation of traditional Chinese medicine food and health products, in particular to a production method of wood frog oil. Background technique [0002] Rana is a well-known economic frog species in my country that integrates medicine, nourishment and beauty. Rana oil is the fallopian tube of the female Rana frog, which contains 18 kinds of amino acids, 13 kinds of inorganic elements, 9 kinds of vitamins and a variety of compound polypeptides and other biologically active factors, especially rich in three sex hormones, namely estradiol, Testosterone, progesterone. Among them, estradiol and testosterone are respectively the hormones with the strongest physiological effects in estrogen and androgen, and have significant functions of nourishing yin, strengthening kidney, stimulating immune function and regulating mechanism. [0003] Rana oil is a protein material that is not easily digested by the human ...

Problems solved by technology

The preparation of existing wood frog oil products generally adopts drying technology, that is, after the whole wood frog is dried, the oil is taken out or the fresh wood frog is dried and stored after the oil is taken out, but the technology of taking the oil after the whole wood frog is dried needs to first dry Live frogs are dried and then softened to extract oil and finally dried. This process requires a long preparation time to dry the wood frog and wood frog oil, which seriously affects industrial production. In the technology of fresh wood frog oil extraction and drying, the forest frog first needs to be dried. The fro
