You can choose one of biochemistry and organic chemistry in the early stage of professional courses, and the other three are English II, Mathematics II and Politics. I took the exam for 20 years. I take organic chemistry as my reference book. The textbook is Organic Chemistry (5th Edition), which was compiled by the Organic Chemistry Teaching and Research Section of Tianjin University.
I applied for a master's degree in materials and chemical engineering (cosmetics), and our master's admission score is not high. I quit my job and prepared for the exam for more than two months. The master's degree is not difficult. Plastic surgery technology is a master's degree, and the admission score is quite high and competitive.
Specialty setting of food biotechnology
This direction mainly uses modern biotechnology means such as genetic engineering, enzyme engineering, fermentation engineering and biological separation engineering to study and deeply apply new natural food resources and provide new functional raw materials and additives for the food industry; At the same time, the prevention and control of waste and pollution in traditional food and food raw material production industries were studied. Formed the following three research levels:
Study on structure-activity relationship of (1) functional components in food. The relationship between chemical structure and function of effective components in plant resources was studied.
(2) Study on the separation and preparation of functional factors and additives with high activity and high added value. With high-speed countercurrent chromatography as the core, combined with other modern extraction and separation technologies, it is used for the separation and purification of natural bioactive components and its application in the deep research and development of edible plant resources, characteristic agricultural and forestry resources and agricultural products.
(3) Research on waste utilization and pollution prevention in food raw material production industry. The production of high protein and multi-enzyme feed by multi-strain fermentation of distiller's grains and nitrification and denitrification of wastewater from amino acid production were studied.
