Rice is the staple food for more than half of the world's population and for more than 60% of China population. Increasing rice yield is therefore crucial for solving food shortage problem, ensuring food secruity, and reducing poverty. Given the vast population and limited per capita cultivated land in China, meeting food demands by increasing the yield per unit area with the aid of advanced sciences and technologies would be the only option. Several alternative measures for increasing crop yield, such as building water conservancy facilities, increasing fertilizer application, improving soil texture, forming interrelated cultivation techniques, more effective controlling of pests and diseases, and using of elite varieties, have been undertaken. Among these alternative measures, adopting elite varieties, particularly popularizing super hybrid rice, proves to be the most economical and effective option. 展开更多

Consumption pattern of beta carotene rich foods from 500 households of Coimbatore district was elicited. Through market surveys in four seasons namely: summer, south-west monsoon, north-east monsoon and winter, a year calendar of beta carotene rich foods was developed. The total and beta carotene contents of five commonly consumed beta carotene rich foods both in raw and cooked states were determined. Results indicated that greens were mainly purchased from market and consumed 2-3 times per week. Cooking loss was maximum in boiling and minimum in shallow fat frying. Curry leaves (Murraya koenigii),amaranth tender (Amaranthus gangeticus), agathi (Sesbania grandopra), and ponnanganni (Alternanthera sessilis) were the carotene rich foods available round the year. Cost of most greens was highest in summer and lowest in north-east monsoon. Within a cost of 13-14 ps in summer, 4-10 ps in south-west monsoon and north-west monsoon and 4-12 ps in winter season, the entire day's requirement of beta carotene (2400μg) could be obtained in the form of agathi/amaranth throughout the year: in the form of drumstick leaves and mint in south-west monsoon; as curry leaves and coriander leaves in winter and as agathi,paruppukeerai and amaranth in summer. From this year calendar, according to seasonal availability and cost, low-cost high carotene foods can be selected and used for increasing the beta carotene intake in the intervention programmes and in the community 展开更多

The no-observed-effect level (NOEL) in a study of carcinogenicity for compounds that are both genotoxic and carcinogenic represents the limit of detection in that bioassay, rather than an estimate of a possible threshold. Therefore, for those genotoxic and carcinogenic contaminants (e.g. acrylamides, PAHs, etc.) in foods it is not possible to develop health-based guidance values (e.g. ADI or PTWI) using the traditional NOEL and safety/uncertainty factors. 展开更多

Whey protein products provided ideal ingredients for nutritional food applications.Whey proteins are known to have high nutritional quality due to their high content of essential amino acids,high digestibility and biological value.Research in the past decades has shown that many of the whey protein fractions and peptides derived from them possess various biological activities.The technology developments in the last decade,such as those in the areas of protein fractionation technologies have made industrial scale production of fractionated whey protein products commercially feasible.The development in hydrolysis technology and the peptide analytical capability allowed production of whey protein hydrolysates with designed bioactivity and functionalities.People are continuously finding new biological activities of the various whey protein fractions or their hydrolysis products.Significant amount of research has also been carried out to study the clinical benefits of some of the whey protein fractions and whey protein derived peptides.Examples of these studies will be reviewed and discussed. 展开更多
