Problems solved by technology

Its characteristic is that the nutrients and volatile components are well preserved, but the processing cost is extremely high, so there are few solid beverages produced by freeze-drying, and only a small number of products with high added value such as instant tea powder and coffee powder are used

Abstract

The invention discloses a preparation technology for composite powder of navel oranges and Chinese gooseberries, which comprises the following steps of: firstly, extracting the polyphenol substances of the navel orange peels, washing fresh and complete navel oranges and Chinese gooseberries by water, respectively peeling and cutting into slices with thickness of 5-10mm, respectively adding the polyphenol substances of the navel orange peels, and filtrating by a filter screen after being pulped and crushed; secondly, respectively obtaining navel orange juice and Chinese gooseberry juice; mixing the navel orange juice and the Chinese gooseberry juice to obtain the mixed normal juice of navel oranges and Chinese gooseberries according to the volume ratio of 5:1-10:5, adding maltodextrin into the concentrated mixed juice, freezing and drying the processed mixed normal juice of navel oranges and Chinese gooseberries in vacuum so as to obtain freeze-dried fruit powder, and mixing with white granulated sugar powder; and thirdly, obtaining the composite powder of navel oranges and Chinese gooseberries. According to the invention, the plant active ingredient polyphenols are extracted from the processing waste, namely the navel orange peels, so that the nutrient Vc (Vitamin C) is protected, the loss of the nutrients is prevented in the processing procedure, and the nutrients and flavour of the mixed juice are more completely stored.

Description

technical field [0001] The invention relates to a preparation process of navel orange-kiwi compound fruit powder. Background technique [0002] Navel oranges are rich in nutrients and contain various nutrients necessary for the human body. Each 100ML fresh orange juice contains: heat 207 joules, protein 0.9g, fat 0.2g, sugar 11.0-13.0g, amino acid 203.9mg, vitamin A 0.127mg, vitamin C 55-75mg, vitamin B 1 0.08mg, vitamin B 2 0.03mg, vitamin C 60mg, soluble solids 11-15%, citric acid 0.80-0.95g. In addition, it is rich in carotene, calcium, phosphorus, iron, magnesium, potassium, sodium, and also contains (R)-lemon oil, coumarin, flavonoids, limonoid analogues, carotenoids, glyceroglycolipids Anti-cancer substances such as ketone, Yridone, and pectin. It is an excellent health-care and nutritious green food.
