Embodiment 1

[0028] A kind of preparation method of deodorization freeze-drying instant Rana oil, described preparation method comprises the following steps:

[0029] (a) First, spray alcohol evenly on the surface of multiple strands of wood frog lint oil, and refrigerate for 10~15 hours, then spread out the multiple strands of wood frog lint oil, and remove the fascia on the surface of the wood frog lint oil at the same time The impurity, obtains the wood frog oil of single strand;

[0030] (b) Soak the single-strand Rana oil obtained in step (a) in alcohol, carry out deodorization and adsorption for 20-40 minutes, take it out, and obtain the primary deodorization Rana oil after the alcohol volatilizes;

[0031] (c) Soak the primary deodorized Rana oil obtained in step (b) in milk, carry out further deodorization treatment for 3-10 minutes, take it out, and rinse off the milk remaining on the surface of Rana oil with running water to obtain secondary deodorized wood frog oil;

[0032] (...

Embodiment 2

[0046] This embodiment is a preferred scheme based on Embodiment 1. The preparation method of the deodorizing freeze-dried instant Rana oil of this embodiment is as follows:

[0047] (a) First, spray 50% alcohol evenly on the surface of multiple strands of wood frog lint oil, and place them in the refrigerator at 4°C for 12 hours, then spread out the multiple strands of wood frog lint oil and remove them at the same time Impurities including fascia on the surface of the wood frog thread oil, to obtain single-strand wood frog oil;

[0048] (b) Soak the single-strand wood frog oil obtained in step (a) in alcohol with a concentration of 95%, take it out after deodorization and adsorption for 30 minutes, and obtain the primary deodorization wood frog oil after the alcohol evaporates; among them, the use of alcohol The amount is 2ml / g wood frog oil;

[0049](c) Soak the primary deodorized Rana oil obtained in step (b) in milk, carry out further deodorization treatment for 5 minute...

Abstract

The invention discloses fishy smell removing freeze-dried instant rana japonica oil and a preparation method thereof. According to the method, softening disassembly, ethyl alcohol fishy smell removing, milk fishy smell removing and freeze-drying are performed on rana japonica oil to prepare the rana japonica oil capable of being eaten directly. The whole technological process is controlled under normal-temperature and low-temperature conditions, in this way, the biological activity components of rana japonica oil are kept, and the fishy smell affecting eating is removed. Meanwhile, the obtained rana japonica oil does not contain any additives, pigments and preservative, can be directly eaten and is easy to absorb by the human body, and the finished product is free of peculiar smells and can be directly used as a raw material of foods and medicines.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a deodorizing freeze-dried instant Rana oil and a preparation method thereof. Background technique [0002] Northeast Rana, referred to as Rana, the oviduct of the female Rana is called Rana oil. Studies have shown that Rana oil has many effects and can improve the body's immunity. It is suitable for men, women and children. Women who eat it can beautify the skin, nourish yin and lungs, regulate endocrine, and delay aging; men who eat it can resist fatigue, nourish yin and strengthen yang, nourish kidney and essence. It is a trusted anti-aging and immune-boosting regulator. But the fishy smell of crude product of wood frog oil is heavier, it is difficult for consumers to take it directly. At present, the deodorization technology of wood frog oil mainly includes masking method, acid-base salt deodorization, heat treatment deodorization (high pressure cooking), microbi...
