Oviductus ranae microcapsules and preparation method thereof

Abstract

The invention discloses oviductus ranae microcapsules and a preparation method thereof, and belongs to the technical field of processing of functional oil and fat products. The microcapsules are prepared with sodium alginate and chitosan serving as wall materials and oviductus ranae serving as a core material. The microcapsules are prepared from, by mass, 1-3% of sodium alginate, 1-3% of chitosan, 1.5-8% of oviductus ranae, 2-6% of anhydrous calcium chloride, 0.5-1% of tween-80, 1% of acetic acid and the balance water. The preparation method of the microcapsules includes the main steps that 1, a wall material solution and an immobilization solution are prepared; 2, oviductus ranae and a sodium alginate solution are mixed according a certain proportion; 3, emulsification homogenization treatment is carried out; 4, the microcapsules are prepared through a piercing-solidifying method. According to the microcapsules and the preparation method thereof, bioactive substances of oviductus ranae are maintained, and many defects of oviductus ranae are overcome. The microcapsules are convenient to preserve, and the fishy smell of oviductus ranae is removed. The preparation method is easy to implement and beneficial for industrial production and opens up a new field for deep processing of rana temporaria.

Description

technical field [0001] The invention belongs to the technical field of processing functional oil products, and relates to a wood frog oil microcapsule and a preparation method thereof. Background technique [0002] Rana oil is the dried oviduct of female frogs. It has the title of "soft gold". It is a precious nourishing nutrient that integrates medicinal, cosmetic and nutritional values. (estradiol, etc.). It has the effects of nourishing kidney and essence, moistening lung and nourishing yin. Rana oil also has the effects of anti-oxidation, regulating blood lipids, improving immune function, and anti-fatigue. It is a rare deep-processing raw material. At present, health food stores mainly sell the original form of Rana oil, and time, temperature, and region have a great influence on it, and the processing process of the original form of Rana oil is also relatively cumbersome. It needs to be soaked in water for 24 hours, and then cooked. edible. The nutrients contained ...

Problems solved by technology

At present, health food stores mainly sell the original form of Rana oil, and time, temperature, and region have a great influence on it, and the processing process of the original form of Rana oil is also relatively cumbersome. It needs to be soaked in water for 24 hours, and then cooked. edible

The nutrients contained in the cooking process are destroyed, and the fishy smell is difficult to remove, and the digestion and absorption rate of the human body is low

Moreover, the development of Rana oil is mainly based on the utilization of protein, while the development and utilization of Rana oil-soluble components is not sufficient, and Rana oil products are not yet complete.
