Abstract

The invention discloses a preparation method of Chinese gooseberry juice, and relates to the field of agricultural processing. The preparation method comprises the following steps: mixing clean Chinese gooseberries with water to obtain a mixture, heating the mixture to 85 to 100 DEG C, carrying out precooking and pulping sequentially to obtain primary Chinese gooseberry slurry; adding pectinase into the primary Chinese gooseberry slurry to obtain a mixture I, and leaving the mixture I to stand still, so as to obtain secondary Chinese gooseberry slurry; conducting centrifugation on the secondary Chinese gooseberry slurry, and removing an upper oil slick layer and a lower precipitation layer to obtain tertiary Chinese gooseberry slurry; diluting the tertiary Chinese gooseberry slurry, adding calcium carbonate for deacidification to ensure that the acidity degree reaches 0.4 to 0.8%, and adding saccharose to ensure that the sugar degree reaches 8 to 12 %, so as to obtain quaternary Chinese gooseberry slurry; adding saccharomyces cerevisiae for fermentation, so as to obtain quinary Chinese gooseberry slurry; adding saccharose into the quinary Chinese gooseberry slurry, then adding a stabilizer, so as to obtain the Chinese gooseberry juice. The preparation method is mainly used for preparing the Chinese gooseberry juice with unique sapor and high nutritional value; the Chinese gooseberry juice prepared according to the preparation method is rich in dietary fiber, vitamins and the like, thereby being a favorable juice product for nutrition supplement.

Description

technical field [0001] The invention relates to a preparation method of kiwi fruit juice, which belongs to the technical field of agricultural product processing. Background technique [0002] my country is the dominant producing area of ​​kiwifruit, with rich variety resources. There are more than 66 kinds of kiwifruit in the world, and there are 62 kinds in my country. Kiwi fruit is not only rich in nutrition, but also has a Vc content dozens of times higher than that of ordinary fruits. It is a high-quality fruit with high nutritional value. It is known as the "king of fruits" and "precious fruit". There are also certain health care effects. Kiwifruit is a thin and juicy berry that is sensitive to ethylene. The harvest period coincides with the high temperature season. The fruit is easy to soften and rot after harvesting, which seriously affects the development of kiwifruit planting industry. Therefore, it is of great significance to study the processing technology of k...
