Application of freeze-drying process in the development of black carp
Lead: Because it is rich in various nutrients, the black sorghum in the desert area of ​​northwest China has always been the title of “soft gold†and “king of anthocyaninâ€. However, due to the problem of preservation of fresh fruits, the industrial development of black carp has been Difficult to develop, and with the application of freeze-drying technology, the development of this industry has seen new hope.
Known as "soft gold" and "king of anthocyanin", black carp is a special product of the desert Gobi region in western China. It is the natural wild plant with the highest OPC content of procyanidins discovered so far. Because it is rich in protein, fat, sugar and various organic acids, vitamins, minerals, trace elements and other nutrients, compared with red peony, black glutinous vitamins, minerals and other nutrients are also richer, especially It also contains natural anthocyanins that can scavenge free radicals and have antioxidant functions, so black mites have also attracted the attention of many health care products manufacturers.
However, due to the difficulty in preserving fresh fruit, the loss of nutrients after drying, and the deterioration of taste, the development industry of black scorpion has been stagnant. Recently, with the application of freeze-drying technology, the development and utilization of black scorpion finally saw the dawn of rapid development.
The application of freeze-drying technology has brought new impetus to the development of black carp
Compared with the traditional drying process, the advantage of the freeze-drying process is obvious: under the same volume, the weight of the freeze-dried product is only 30% of the dried, while the product of the same quality is 4 times that of the dried. The black sorghum processed by freeze-drying technology is full and bright, and the difference from ordinary dried fruits is indeed obvious. Moreover, the lyophilized product generally has the characteristics of strong rehydration, and the lyophilized black sputum which has been chilled at a low temperature can be immediately restored to a fresh state. Another major advantage of freeze-dried black mites is that after low temperature operation, there will be no oxidation reaction, less nutrient loss, long storage time, and more beneficial to human body absorption.
Freeze-drying technology brings new hope to the development of “soft goldâ€, and it also shows people the huge potential of this technology in the field of food and health care processing. However, the lack of relevant matching freeze dryer equipment, optimization of freeze-drying process, etc., the promotion of freeze-drying technology in the food processing industry is still an urgent problem to be solved. Fortunately, some freeze dryer manufacturers have already seen this problem. For example, Beijing Bo Yikang, which has nearly 20 years of experience in the production of freeze dryers, has recently launched a drug production application. The Pilot-E series freeze dryers, targeted design and process optimization, make this series especially suitable for the daily production of small and medium-sized food companies. The promotion of such products, I believe, can also make the application of freeze-drying technology in the field of food production to a new level.
