Abstract:The outline and the latest progress of the studies in the world on natural edible antioxidants are reviewed. Novelty and practicality of these studies are dealt with in this paper. More than sixty up-to-date references are provided.

Abstract:This paper presents an optimized technology of phytic acid prepared by aqueous H_2SO_4 extracts from wastes of the food industry, which saves investment of production owing to avoiding anion-exchange. The purity of products is high to 87.7% and the yeild

Abstract:This paper investigates the relationship between the palatabilities of various varieties of rice and their physical and chemical parameters through a research on these parameters and the whiteness of rice, Thus the amylose content, gelatinization temperat

Abstract:Fission yeast, schizosaccharomyces pombe, can not be used for fermenting xylose sugar and for cell growth. However, the yeast can be used to ferment xylulose, an isomerized product of xylose, to ethanol with high yield and efficiency. This shows that a xy

Abstract:How to control the attenuation of the beer reasonably and accurately is studied from fermentation control with the quantitative concept. It is shown through practice that the relation between the apparent sugar content and alcohol strength can be determin

Abstract:On the basis of previous technology, a new method for extracting gum from the endosperm of sesbania cannabina (S. C.) seed was tested, in which gum was extracted directly from S. C. seed rather than after separation of the endosperm from the seed. The pro

Abstract:Mathematical model of pottery drilling by pulsed laser beam is established. The law of pottery drilling by pulsed lasers and way of optimisation of manufacturing parameters are analysed.

Abstract:This paper discusses transmission characteristic of corrected tooth chain designed by "envelope-path" method, and this article also puts forward the improvement of the method according to correction tooth design in order to basically eliminate the polygon

Abstract:This paper introduces the expansive method of TP801 hardware function, including the expansion of ROM, RAM and the interace such as Z80-PIO, Z80-CTG, LED; and the method of connecting Z80-SIO, A/D, D/A to micrcocomputers. This paper is a good reference fo
