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

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with embodiment:

[0027] (1) Artificial induced labor: before the forest frog hibernates in early November, catch artificially raised forest frogs, half male and half male, and put them in an indoor cement pool with a water depth of 15 cm. The water temperature is controlled at 18 °C, and the stocking density is 5 pairs / square meters, after half a month the frogs will hug each other and lay eggs;

[0028] (2) Centrifugal separation: fish out the eggs discharged from the body, place them in the container of the centrifuge, and centrifuge at a speed of 4000 rpm for 10 minutes;

[0029] (3) Obtain egg capsules, i.e. toad oil, and ovum cells: take out the ovum capsules located in the white part above the container of the centrifuge, i.e. toad oil, and the ovum cells in the black part of the lower floor (can be dried and pulverized to make egg yolk powder);

[0030] (4) Put back for overwinteri...

Abstract

The invention discloses a method for harvesting toad oil in a non-injurious way to wood frogs, and belongs to the technical field of obtaining protein from animal eggs. Including the steps of artificial induction, centrifugation, obtaining egg capsules and egg cells, and putting them back for overwintering. That is, before the hibernation of the forest frogs every year, the forest frogs, which are half male and half female, are caught and stocked together. After half a month, the forest frogs hug each other and lay eggs; Place in a centrifuge for centrifugation; take out the egg capsules located in the upper white part and the egg cells in the lower black part; put the male and female wood frogs back into the wintering waters to survive the winter naturally. The present invention adopts artificial oxytocin technology and centrifugal separation technology in winter non-breeding seasons to harvest egg capsules (toad oil), which has completely changed the traditional processing method of slaughtering wood frogs and dissecting oviducts (toad oil) in the past, and also made up for "living wood frogs". The method for extracting oil from the existing technology is more suitable for commercial batch production, fully and effectively utilizes the forest frog resource, improves the economic benefit of the forest frog production, and protects the ecological environment.

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...
