Abstract

The invention discloses a rana japonica oil fermented drink and a method for preparing the same and belongs to the technical field of food processing. The method for preparing the product disclosed by the invention comprises the following main steps of: according to the volume percentage of a fermentation substrate, inoculating the fermentation substrate which contains 4-10% of whey protein concentrate, 0.1-1% of inulin, 1-3% of fructo-oligose, 1-10% of honey, 5-15% of sugar and the balance of rana japonica oil with 1-10% of Kefir starter, fermenting at 20-30 DEG C for 6-20 hours, and homogenizing and cooling, and then performing sterile filling, thereby obtaining the rana japonica oil fermented drink. The rana japonica oil fermented drink disclosed by the invention is rich in active probiotics and various functional components, thereby having the effects of regulating intestinal flora balance, maintaining the intestinal health, reducing blood fat, protecting the liver, resisting cancer, beautifying and the like; and therefore, a new way is opened for deep processing of the rana japonica oil.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a wood frog oil fermented drink and a preparation method thereof. Background technique [0002] Rana oil is the dried fallopian tube of the female Rana, and it is a precious nourishing health product, which has the functions of nourishing the kidney and essence, moistening the lungs and nourishing yin. At present, the development of Rana oil in my country is still in its infancy, mainly focusing on the development of Rana oil capsules, Rana oil oral liquid, and Rana oil beverages. There are disadvantages such as simple technology, low product added value, single type, unacceptable taste, etc. Therefore, combined with modern food processing technology, the development of products with high nutritional value, unique flavor and good taste has great economic value and development prospects. [0003] Kefir starter is a starter that can simultaneously carry out lac...
