Abstract

The invention relates to the technical field of food processing, and concretely relates to a Nitraria tangutorum Bobr berry powder preparation method with wild Nitraria tangutorum Bobr berries as a raw material. The Nitraria tangutorum Bobr berry preparation method comprises the following steps: 1, cleaning; 2, juicing, carrying out color protection, and carrying out enzyme processing; 3, carrying out membrane filtration; 4, disinfecting; 5, spray-drying; and 6, detecting and packaging: determining all indexes of the Nitraria tangutorum Bobr berry powder, and packaging by small packaging bags to form the finished Nitraria tangutorum Bobr berry powder. The invention provides an improved technical scheme for the comprehensive utilization of a Nitraria tangutorum Bobr berry juice and solves problems that the Nitraria tangutorum Bobr berry juice is only used for preparing beverages and low-end products and the juice is difficult to preserve, the berry powder has the advantages of safety and simplicity, product added value improvement and the like, and preconditions are provided for the large scale processing of Nitraria tangutorum Bobr to a great degree.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a preparation method of Nitraria berry powder using wild Nitraria berries as raw materials. Background technique [0002] Nitraria is a wild shrub belonging to Tribulus terrestae. It mainly grows in the Gobi Desert and the edge of the desert. Nitraria resources are rich in output and widely distributed in my country, but they are relatively concentrated in the Qaidam area of ​​Qinghai, and the conditions for development and utilization are superior. The Nitraria in the Qaidam area is distributed in non-polluted areas above 3,000 meters above sea level, with resources of 1.5 to 2 million mu. The relatively concentrated distribution of Nitraria forest with development value is about 500,000 mu, and the annual production of Nitraria fruit is 6~2 million mu. 100,000 tons, about 50,000 tons of fruit juice can be processed annually. The resources are very rich and need to be d...
