Generally, the raw material of extract is plant. Through the physical chemistry processes of extraction and separation, one or more active ingredients that are directly obtained and concentrated from the plants without changing their structures are the extracts. Currently, the application scope of extracts is constantly expanding. Extraction equipment plays an important role in the extraction process.
In recent years, China's food industry has developed rapidly, and the food processing equipments also developed fast and more and more different types food processing equipments were created and available in the market. Meanwhile, the technologies of extraction equipments and extraction techniques also made breakthroughs, different methods, equipments and technologies are applied to the extraction of different materials.
However, the international markets pay more and more attentions to the quality and safety of the extracts. The extraction processes of varieties materials are complicated projects and are related to the relevant extraction equipments and extraction techniques more or less. By improving the comprehensive performance of the extraction machines and controlling the quality and safety of the whole extraction process strictly, it is sure that the quality and safety of extracts will be improved effectively.
The author believed that: as the international demand for the natural pigments and safe food additives keeps growing, the international market will not only provide a great development opportunity for the extract markets but also provide a good development opportunity for the manufacturing industry of the food biochemistry equipment. Therefore, the relevant manufacturing enterprises of food processing machinery should enlarge business in their field, increase the R&D investment, develop new products and provide equipment supports for enlarging the applications of extracts in healthy food industry.
