Processing method of high-quality roxburgh rose powder

Abstract

The invention discloses a processing method of high-quality roxburgh rose powder. The processing method comprises the following steps of putting selected roxburgh rose fruits in a roller cleaning machine, and after stabs on the outer peels of the roxburgh rose fruits fall down, taking out the treated roxburgh rose fruits for standby application; squeezing the cleaned roxburgh rose fruits to obtainjuice; adding a gelatine solution, and pouring clarified roxburgh rose juice into a filter drum; and performing reverse osmosis treatment on the treated roxburgh rose juice, pouring the roxburgh rosejuice after reverse osmosis treatment in a freeze drier, and performing freeze drying on the roxburgh rose juice to obtain powder namely the roxburgh rose powder. According to the processing method,in the process of producing the roxburgh rose powder, the roxburgh rose juice is in the normal-temperature or low-temperature state, components of vitamins and the like in the roxburgh rose cannot bedamaged by high temperature, nutrient components in the roxburgh rose are effectively preserved, and besides, before freeze drying, the roxburgh rose juice is subjected to primary reverse osmosis, sothat most of moisture in the roxburgh rose juice is removed, the energy is saved, the efficiency of the entire production flow is improved, the load of the freeze drier is low, and the production costis reduced.

Description

Technical field [0001] The invention relates to the technical field of food processing, in particular to a method for processing high-quality prickly pear powder. Background technique [0002] Prickly pear, also known as Sending Spring Return, belongs to the wild plant of Rosaceae. It is a wild resource unique to the Yunnan-Guizhou Plateau and Panxi Plateau. It is mainly produced in Guizhou, followed by Yunnan, and is also distributed in Henan, Sichuan, Daliang Mountain, and western Hubei. Prickly pear is rich in many nutrients, especially the vitamin C content is surprisingly high. Prickly pear dried fruit is sun-dried or dried from fresh prickly pear fruit. Generally, it retains more than 90% of the nutrients and loses moisture. On the contrary, the nutrient content per 100g of dried fruit is more than twice higher than that of 100g of fresh fruit. [0003] At present, most of the prickly pear products sold on the market are juice-based crude extracts. These products have high i...

Problems solved by technology

[0003] At present, most of the thorn pear products sold on the market are rough extraction products of fruit juice. These products have high impurity content, are prone to turbidity, have a short shelf life, and are difficult to carry out large-scale circulation and sales. prickly pear powder

[0004] Chinese patent CN101167553A discloses a processing method for preparing thorn pear powder from crudely extracted thorn pear juice. The disadvantage of this invention is that if spray drying is used in the drying part, the high temperature generated in the spray drying process will destroy the thorn pear. Vitamins and other nutrients in the product cause nutrient loss, resulting in unsatisfactory fineness of Rosa roxburghii powder. If freeze-drying is used in the drying part, a large amount of electricity will be consumed in mass production, and the drying process takes a long time, resulting in The efficiency of the whole production process is low, and at the same time, the load of the freeze dryer is very large, which increases the equipment investment and later maintenance costs of the enterprise in the production process, and increases the production cost
