Potato is a vital food-security crop and substitute for cereal crop considering its high yield and great nutritive value. Therefore, by replacing wheat, rice or maize in traditional staple foods partly by potato, the nutritional value of traditional foods and the utilization of potato are expected to be improved. China is the largest potato producer worldwide in terms of either volume or area. However, majority of potatoes are consumed as fresh vegetables for cuisine, and the industrial processing rate is much lower than the global average. Thus, research and development for nutritional potato stable food suitable for the dietary habits of Chinese residents are of great significance. However, we still confronted plenty of constraints in the development of potato staple food. In order to develop potato staple food suitable for Chinese residents＇ dietary habit like noodles, Mantou（steamed bread）, rice and rice noodles, also to industrialize production of potato staple foods, some transformations need to be realized. Independent innovation is the only choice to realize the potato staple food processing and industrial development strategy on the technical level. Thus a lot of researches have been done to promote the development of potato staple food in China. Up to now, we already developed a series kinds of potato staple foods and some of these staple foods have already been widely promoted in Chinese markets.展开更多

Mycotoxins are toxic secondary metabolites produced by fungi when they grow in agro-food products and feedstuff. Several detection techniques have been developed in recent years to detect mycotoxins in the food and feed effectively. HPLC based tech- niques are very common in usage in the laboratories for the testing of mycotoxins. In recent years, immuno-based assays is widely used and have been reported at large due to its sensitivity and limited detection time. Immuno assay-based kits were developed effectively to be used in the fields and in storage systems to detect the mycotoxin levels. Microarray-based immunoassays developed in the recent years could simultaneously detect afiatoxin, ochratoxin, and zearalenone with the higher sensitivity. Aptamer-based assays could target the detection of ochratoxin and aflatoxins and fumonisins at high specificity in food products. In recent years, several assays reported for the simultaneous multiple detection of different mycotoxin was based on HPLC and LC-MS/MS. There is a need for the use of these advanced technologies in the com- mercial scale.展开更多
