Abstract

The invention relates to the field of fruit processing and especially relates to wild pyrus ussuriensis maxim freeze-dried powder and a standard thereof. A vacuum freeze-drying process comprises feeding pre-frozen fruit paste into a drying cabin, starting a vacuum pump, keeping vacuum pressure of 15pa, slowly heating the fruit paste to -30 DEG C at a heating rate of 1 DEG C / h, keeping the temperature for 12h, slowly heating the fruit paste to -5 DEG C at a heating rate of 2 DEG C / h, keeping the temperature for 8h so that a first drying stage is finished, on the premise of enzyme activity guarantee, slowly heating the fruit paste to 40 DEG C at a heating rate of 3 DEG C / h, keeping the temperature for 8h and taking the fruit paste out of the cabin. A detection result shows that the wild pyrus ussuriensis maxim freeze-dried powder comprises less than or equal to 9.0% of water, less than or equal to 5.0g / 100g of total acids, less than or equal to 0.5mg / kg of total arsenic, less than or equal to 0.05mg / kg of cadmium and less than or equal to 1.0mg / kg of lead, and has less than or equal to 1000cfu / g of total bacterial count, less than or equal to 30MPN / 100g of count of coliform bacteria and 50cfu / g of fungal count. The wild pyrus ussuriensis maxim freeze-dried powder has scientific and reasonable quality indexes and gets the guarantee.

Description

[0001] technical field [0002] The invention relates to the field of fruit processing, namely the freeze-dried wild pear powder and its standard. Background technique [0003] In the prior art, with the rapid development of modern food processing technology and the remarkable improvement of people's living standards, the demand for health products that are convenient to use in people's daily life is becoming more and more extensive. The acidity, aroma and sugar content of sorbis far exceed those of other pear varieties. Sorbet fruit contains rich nutrients such as sugar, organic acids, pectin, vitamin C, and minerals. Sorbet is suitable for processing various products because of its high acid content and unique fragrance, but there is no report on the deep-processing products of this fruit. From the point of view of the utilization of pear resources in our country, it is relatively simple. More than 90% of them are fresh varieties and lack of processed varieties and charact...
