Method for non-invasive collection of toad oil from forest frog

Abstract

This invention relates to a method for recovering the forest frog's oviduct in a non-harmful way, belonging to the technological field of acquiring proteins from animal eggs. The process comprises of artificial spawning stimulation, centrifugal separation, acquiring egg capsules and egg cells, and putting back for hibernation. Concretely, it comprises: fishing fifty-fifty male and female wood frogs for centralized breeding before the wood frog's hibernation, leaving the wood frogs to mate and lay eggs half a month later, centrifuging the eggs, collecting the egg capsules from the white upper layer and the egg cells from the black sublayer respectively, and putting the male and female wood frogs back to the watershed for their hibernation. This invention is characterized in that, by using artificial spawning stimulation and centrifugal separation technologies to recover egg caplsules(forest frog's oviduct) in winter non-breeding season, it thoroughly changes the traditional process of recovering egg caplsules by killing the wood frogs, covers the shortage of current technology-oviduct recovering method from living wood frogs, makes it more qualified for commercial batch production, makes full and efficien use of wood frog resources, improves economic benefits of wood frog production and protects the ecologic environment as well.

Description

technical field [0001] The invention belongs to the technical field of obtaining protein from animal eggs, and in particular relates to a method for non-damaging harvesting of toad oil from wood frogs. Background technique [0002] The commonly referred to as forest frog refers to the scientific name of Chinese forest frog (Rana temporaria chensinensis) and Heilongjiang forest frog (Rana amurensis). It is called "toad oil" and "wood frog oil", and the Cantonese call it "xueha ointment". It is a traditional and effective animal medicinal material and a specialty of Northeast China. It is recorded in "Compendium of Materia Medica" and "Pharmacopoeia of the People's Republic of China" that toad oil is warm in nature, returns to the lung and kidney meridian, and has the effects of nourishing kidney and essence, nourishing yin and moistening lung, nourishing deficiency and reducing fever. [0003] Toad oil mainly contains protein, fat only accounts for 4%, and also contains estr...

AI Technical Summary

Problems solved by technology

[0007] (1) To collect wood frogs in March, it needs to be caught in advance and artificially overwintered for 4 months, which is not conducive to the preservation of wood frogs;

[0008] (2) Using artificial methods to ovulate, it is not easy to control with force, and it is easy to cause damage to the oviduct and other parts of the wood frog, which will affect future reproduction and utilization;

[0009] (3) Eggs and egg capsules (toad oil) need to be naturally dried for several days before separation, and soaked in hot water at 40-50°C for 24-48 hours. The active ingredients are easily destroyed and moldy during processing. , the separation is fully manual, and the quality is not easy to control
