Problems solved by technology

At present, the soaking time of water usually takes several hours, which is easy to breed the risk of spoilage microorganisms; in addition, the existing products usually contain a certain fishy smell, which affects the sensory taste. It has been reported that the way to remove the fishy smell of Rana oil is mostly to add ginger, or At the same time, ethanol and ginger (authorized patent CN102599262B) are added for processing. The method uses spices to correct the taste, which has the problem of incomplete deodorization and changes in the original taste of the product; on the other hand, due to the addition of external ethanol, it is difficult to remove during processing

preparation example Construction

[0016] A method for preparing wood frog oil, characterized in that it comprises the following steps:

[0017] (1) the dry wood frog oil is pulverized into powder for removing impurities;

[0018] (2) add water, pass into ozone at the same time, soak and soak hair, dehydrate;

[0019] Among them, the removal of impurities includes the removal of connective tissue, oil film and egg grains; the temperature of adding water, introducing ozone and soaking and soaking hair is 4-10°C; the mass ratio of dry wood frog oil to water is 1:80-1:120; ozone The concentration in water is 0.5-1mg / L, and the infusion time is 15-30min; the soaking temperature is 4-10℃, and the time is 12-24h; the dehydration method is filtration or drying.

Embodiment 1

[0022] Prepare wood frog oil with preparation method described in the present invention, comprise the following steps:

[0023] (1) Dry Rana oil pretreatment: remove connective tissue, oil film and eggs;

[0024] (2) classification: pulverized through 40 mesh sieve classification;

[0025] (3) Soaking hair: add water to soak the Rana oil of step (2) under different temperature conditions (4, 6, 10, 15° C.), simultaneously pass through ozone for 15 minutes, and airtightly immerse and soak for 12 hours;

[0026] Wherein the weight ratio of water and dry wood frog oil is 80:1, and the concentration of ozone in water is 0.5mg / L.

[0027] (4) Dehydration: the 4 groups of wood frog oils in step (3) are filtered through gauze to remove water respectively, and the wood frog oil is obtained.

[0028] The sensory evaluation and the total number of bacterial colonies were carried out on the Rana oil obtained by soaking under the above-mentioned different temperature conditions. The sen...

Abstract

The invention discloses an oviductus ranae preparation method, which comprises: pre-treating dry oviductus ranae; adding purified water at a low temperature while introducing ozone; and carrying out impregnating swelling, and dewatering to obtain the oviductus ranae. The invention further discloses a food prepared by using the method. According to the oviductus ranae prepared by using the method and the food, the problems of rotting and fishy odor due to the soaking swelling of the dry oviductus ranae through water are solved, the original structure of the oviductus ranae is maintained, and the good taste is provided.

Description

technical field [0001] The invention relates to the field of food, in particular to a preparation method of wood frog oil and instant food of wood frog oil. Background technique [0002] Rana oil (Ha toad oil) is obtained by collecting and drying the oviducts of the female Rana chinensis. Rich in the reputation of nourishing "soft gold", it was once listed as a royal tribute in the Qing Dynasty. So far, the chemical components that have been found include proteins, amino acids, fatty acids, nucleic acids, vitamins, carbohydrates, phospholipids, hormones, steroids, etc. Most of the products developed with wood frog oil as the main raw material are oral liquids, granules, soft capsules, granules, tablets, beverages, etc. The above-mentioned products generally need to be processed through multiple processes and dilution ratios, which inevitably damage the natural nutritional and health components of Rana oil, and the final product contains less Rana oil; moreover, the origina...
