Effects of nitrogen application rate on spatiotemporal variability of biomass accumulation of cotton s fruiting branch at flower and boll stage.;

The present research investigates the effects of ultra high pressure treatment on soluble proteins,peroxidase(POD)and pectin methyl esterase(PME)of litchi pulp,and the effect of ultra high pressure treatment together with citric acid ,L-ascorbate, calcium chloride on peroxidase(POD)and pectin methyl esterase(PME)of litchi pulp.

In order to investigate the effects of combined treatment of ultra high pressure(UHP) and enzyme inhibitors on the activities of peroxidase(POD) and pectin methyl esterase(PME)in litchi pulp,two kinds of enzyme inhibitor prescriptions were designed including group A(citric acid 5 g/L+L-ascorbic acid 2.

A GC-MS method was developed for the fatty acid composition analysis of litchi pulp.

The extraction and the stability of anthocyaninin litchi pericarp;

The mono-factor experiment of microwave extraction of antioxidant from Litchi pericarp shows that the optimum condition for the extraction is as follows: the litchi pericarp and 95% (v/v)ethanol were put in sealed jars with ratio of 1︰20 (g/ml) to extract for 60s under microwave radiation at power of 400w.

The study on the absorption spectrum changes of carbinol extraction (pH=3 00±0 01) of litchi pericarp against the natural light within PE bags of different colours (black, blue, green, yellow and white) was made.
