Description

Pickled vegetable-flavor carmine radish powder and processing method thereof
Technical Field
The invention belongs to the field of deep processing of vegetables, and particularly relates to pickled vegetable flavored carmine radish powder and a processing method thereof.
Background
The vegetables are limited by seasons, have short shelf life after being mature, and are easy to wither, brown or rot and deteriorate. According to statistics, China is the first major vegetable production country in the world, and the annual vegetable loss rate of China is as high as 30-40% (Bijinfeng, celery, Liuhua, and the like, the current state of fruit and vegetable powder processing technology and industry at home and abroad and the prospect [ J ] Chinese food academy, 2013,13(3):8-14), so that huge economic loss and resource waste are caused. Chinese vegetables are mainly processed and eaten simply, the number of the vegetables used for processing products such as cans, pickled products, dry products and the like is less than 5%, and low processing utilization rate is an important factor influencing the vegetable loss rate in China. The vegetable powder is processed into vegetable powder, so that the moisture content and the water activity in the vegetable are reduced, the shelf life of the vegetable powder can be greatly prolonged, the vegetable powder is favorable for storage and transportation and can be used as a food ingredient, and the loss of nutrients of the vegetable powder in the processing process and the storage process can be controlled through the drying method and the auxiliary material selection in the processing process. Meanwhile, the vegetable powder can meet the requirements of special crowds such as patients, old people, infants and the like. The method converts fresh vegetables into powder, and has wide development and application prospects in the aspects of better meeting the requirements of consumers, ensuring the nutritional functional characteristics of products, reducing vegetable loss and economic loss and the like.
A carmine radish, also known as Fuling red heart radish, is famous for full red skin and flesh and rich in radish red pigment, and is a local variety unique to Chinese radish (Raphanussatvus L. The radish red pigment contained in the carmine radish has strong water solubility and is mainly used for extracting and preparing natural food pigment radish red.
At present, the processing level of carmine radish is not high, the intensive processing and the comprehensive utilization of carmine radish are carried out, the additional value of carmine radish can be increased, and the processing benefit is improved. The carmine radish is rich in nutrients needed by people, such as saccharides, proteins, vitamins, minerals, dietary fibers and the like, and also contains biological active substances, such as polyphenol, carotenoid, anthocyanin and the like, which promote the health of the body and prevent chronic diseases. Earlier researches show that fresh carmine radish is directly processed into radish powder, the bad radish flavor generated by processing is difficult to remove, pigments are subjected to oxidative degradation in a hot air drying process, and the powder has poor flowability.
Disclosure of Invention
In order to solve the problems, the invention provides pickled carmine radish powder with pickled carmine radish flavor and a processing method thereof by taking the traditional manufacturing idea of carmine radish pickled vegetables as reference.
The pickled carmine radish powder is prepared by crushing pickled and fermented carmine radish; the soaking fermentation is to mix the carmine radish salted by salt with spices, uniformly stir the mixture, put the mixture into a soaking jar, add salt water into the soaking jar, and perform sealed fermentation; the flavoring is a combination of one or more of common flavorings in the food industry; the carmine radish is also named Fuling red heart radish, is famous for full red skin and flesh and rich in radish red pigment, and is a unique local variety of Chinese radish (Raphanussatvus L.var.longipinnatus Bailey).

As can be seen from table 7, the kimchi flavor carmine radish powder prepared by the present invention not only imparted kimchi flavor to the radish powder but also removed the bad flavor of the radish powder by the fermentation action of microorganisms through the process of brewing and fermentation. The special flavoring is added in the brewing and fermenting step, so that the radish powder is more sour, cool and spicy.
In comparison with examples 1 and 4, the color of the radish powder is bright red by the auxiliary color effect of the color fixative such as organic acid, amino acid and the like to help maintain the color of the pigment. Examples 1 and 3 compare, and example 1 stabilizes the flavor of kimchi by molecular encapsulation and carrier encapsulation techniques. Compared with the embodiment 2, in the embodiment 1, the drying assistant is added, and the spray drying method is adopted to accelerate the accelerated drying of the radish mixed liquid, so that the phenomenon that the radish mixed liquid is deteriorated in the air drying process in the traditional industry is avoided. Example 4 compares with example 6, and example 6 adopts a process of drying and then crushing, so that the carmine radish powder can still maintain the flavor of the pickle and remove the bad flavor, and has sour, spicy and hot mouthfeel.
As can be seen from example 8, the kimchi-flavored carmine radish powder prepared by the present processing method can be used as a food processing ingredient, and can color (radish red pigment), restructure (added as a vegetable powder), fortify nutrients, and adjust flavor (kimchi flavor) to foods. The method has practical value for improving the processing level of the carmine radish, increasing the variety of deep-processed products and widening the application range of the carmine radish in the food industry.
