Description

3D printing chocolate and preparation method and application thereof
Technical Field
The invention belongs to the field of food processing, and particularly relates to 3D printing chocolate and a preparation method and application thereof.
Background
The 3D food printing technology is to print food. The 3D food printer uses not ink cartridges, but food materials and ingredients are put into a container in advance, then a printing program is input, corresponding 3D graphics are printed according to a set 3D template, and the output is not a file which is one by one, but the food with the belly can be actually eaten. The food 3D printing technology is an emerging food processing technology, integrates various technologies such as a digitizing technology and a food processing technology, and has the advantages of individuation, nutrition, safety and various shapes. In recent years, 3D printing technology has been widely applied in the food industry for meeting the personalized needs of consumers for food appearance, morphology, nutrition, etc., and food 3D printing technology has led to rapid development of personalized accurate nutrition.
Compared with traditional food production, the 3D printed food does not need to purchase fresh raw materials, a chef or heating equipment, the whole process is automatic and unmanned, and the printed food is ready to eat. The 3D printed food can realize personalized customization of modeling, and is manufactured into various fancy and unique appearance. The method changes the appearance of single food in the traditional food processing, and meets the requirements of people for fashion and improving the taste of life. The nutritional composition of the food can also be adjusted by adjusting the proportion of the raw materials, so that the health requirements of different individuals can be met.
Chocolate is a mixture with cocoa butter as the main continuous phase and sugar, cocoa powder and other ingredients as the disperse phase, the main ingredient of which is cocoa butter. The unique flavor and taste of chocolate makes it popular with people worldwide.
The 3D technology has the potential to personalize the shape and texture of chocolate and meet the requirements of nutrition, flavor and texture, so that people can manufacture food according to personal preference, and visual food attraction is improved. However, 3D printing of chocolate involves precise control of melting and recrystallization of cocoa butter, and therefore, development of 3D printed chocolate is a hotspot in research on food 3D printing technology.
The common chocolate formula has larger viscosity, is easy to block holes, is too thin, can not be molded by printing, is unfavorable for extrusion molding of 3D printing, can not realize rapid solidification after printing, and has molding defects. In addition, common chocolate has high cocoa butter content, while cocoa butter saturated fatty acid content is high, and excessive consumption of saturated fatty acid may cause health problems such as hyperlipidemia, diabetes, obesity, etc.
In order to solve the problems of high cost and limited supply of cocoa butter; the difficulty of crystallization control is high, and the taste and stability of chocolate are greatly affected by the poor crystallization process; the problem of high saturated fatty acid content, and the like, is also that in order to meet the demands of modern people on low-fat and low-calorie foods, the food industry is searching for cocoa butter alternatives, and the development of fat-reducing chocolate aiming at reducing the cocoa butter content is started.
Plant polyphenols are a large class of phenolic substances widely existing in plant tissues, and many plant polyphenols have excellent antioxidant, anticancer and other various biological activities. With the enhancement of consumer nutritional functional appeal to foods, the development of functional foods based on plant polyphenols is of great interest in the food industry. The natural plant polyphenol active substances are added into the chocolate to realize the functionalization of chocolate products, so that healthy chocolate with more nutrition and functionality is developed abroad, and some researches are carried out. However, domestic functional chocolate related research is relatively lagged, and functional chocolate on the market has few varieties and weak functionality.
