Embodiment 1

[0053] Mix blueberry juice a, purple sweet potato juice a, and mulberry juice a in a ratio of 4:4:2, and then add citric acid in an amount of 1.0% of the mass of the three mixed juices of blueberry juice, purple sweet potato juice, and mulberry juice; The amount of rock sugar added is 5.0% of the mass of the three mixed juices of blueberry juice, purple sweet potato juice and mulberry juice, dissolved and mixed evenly;

[0054] Homogenize the mixed solution for 5 times under a pressure of 40MPa. The degassing pressure is controlled at 2 Pa, and the time is 5 minutes; the degassed solution is filled and sealed. Ultra-high pressure was used for sterilization, the pressure was 500 MPa, and the processing time was 15 minutes to obtain compound beverage 1.

Embodiment 2

[0056] Mix blueberry juice b, purple sweet potato juice b, and mulberry juice b at a ratio of 4:4:2, and then add citric acid in an amount of 1.0% of the mass of the three mixed juices of blueberry juice, purple sweet potato juice, and mulberry juice; The amount of rock sugar added is 5.0% of the mass of the three mixed juices of blueberry juice, purple sweet potato juice and mulberry juice, dissolved and mixed evenly;

[0057] Homogenize the mixed solution 4 times under a pressure of 40 MPa. The degassing pressure is controlled at 2 Pa, and the time is 5 minutes; the degassed solution is filled and sealed. Ultra-high pressure was used for sterilization, the pressure was 500 MPa, and the processing time was 15 minutes to obtain compound beverage 2.

Embodiment 3

[0059] Mix blueberry juice b, purple sweet potato juice b, and mulberry juice in a ratio of 3:4:3, and then add citric acid in an amount of 0.5% of the mass of the three mixed juices of blueberry juice, purple sweet potato juice, and mulberry juice; The amount of rock sugar added is 8.0% of the mass of the three mixed juices of blueberry juice, purple sweet potato juice and mulberry juice, dissolved and mixed evenly;

[0060] Homogenize the mixed solution for 5 times under a pressure of 40MPa. The degassing pressure is controlled at 10 Pa, and the time is 5 minutes; the degassed solution is filled and sealed. Ultra-high pressure was used for sterilization, the pressure was 500 MPa, and the processing time was 15 minutes to obtain compound beverage 3.

Abstract

The invention relates to a blueberry/purple sweet potato compound beverage which is processed from the following main ingredients: blueberry, purple sweet potato and mulberry, and a preparation method thereof, and belongs to the technical field of food deep processing. The blueberry/purple sweet potato compound beverage is made by special proportioning and compounding of purple blueberry juice, purple sweet potato juice, mulberry juice and auxiliary ingredients. The raw materials are selected, and the three kinds of juices are mixed at a certain ratio. The compound beverage retains the flavors and nutrients in the raw materials to the greatest extent, has a higher nutritional value, is rich in vitamins, minerals and active components, and has no the problems that the purple sweet potato juice has a plain taste and the blueberry juice is not sour or sweet. The preparation method provided by the invention has the characteristics of simple process, low working temperature and less nutrient loss.

Description

technical field [0001] The invention relates to a blueberry-purple-sweet-potato compound drink processed from blueberries, purple-sweet-potatoes and mulberries as main raw materials and a preparation method thereof, belonging to the technical field of food deep processing. Background technique [0002] Blueberries belong to the genus Vaccinium of Rhododendronaceae, and their planting history is relatively short. The United States is the earliest country in the world to cultivate blueberries, but it has a history of less than one hundred years. In recent years, my country's blueberry planting industry has developed rapidly, and Qingdao Jiaonan has become the largest planting base in the country. Because of its high health and nutritional value, it is popular all over the world. The edible rate of blueberry reaches 100%. The Food and Agriculture Organization of the United Nations lists it as one of the five health foods for human beings. It is known as the "golden berry". The...
