  • In this study, removal effect of residue pesticides on vegetable and fruit using organic acid salt in alkali solution were investigated by gas chromatography and measurement of detergency. Generally, for the removal methods of residue pesticides and oily pollution were used chemical detergent or organic solvent. Specially, in our experiment, we only used material of food additives and trisodium citrate were superior to other organic acid salt. It was investigated that removal effect of pesticides was superior to chemical detergent.

  • This study was conducted to evaluate the effects of dietary pitamin, pine bark extracts, as a organic livestock feed additives on the egg production and egg quality of laying hens. One hundred-fifty laying hens (Hyline brown) were randomly allocated to one of the following 3 treatment groups for 6 weeks: control, pitamin 0.1% and pitamin 0.2%. The egg production of hens fed the diet containing 0.1% pitamin was similar to that of the control; however, the egg production of the pitamin 0.2% group was significantly lower than that of the other groups (p<0.05). Additionally, the Haugh unit was higher in groups fed diets that contained 0.1% or 0.2% pitamin than in the control group (p<0.05), but no significant difference in egg shell thickness and egg shell breaking was observed between the pitamin 0.1% group and the control group. Furthermore, the concentration of cholesterol in eggs produced by the pitamin 0.1% group was significantly lower than that of the other groups (p<0.05). Moreover, the saturated fatty acid content of eggs from hens in the pitamin 0.2% group was lower than that of eggs produced by hens in the other groups, whereas the unsaturated fatty acid content of eggs produced by hens in the pitamin 0.2% group was higher than that of eggs produced by hens in the other groups (p<0.05). Finally, the values corresponding to the storage days, Haugh unit, yolk index and albumin index of eggs produced by hens that were provided with a diet that contained 0.1% or 0.2% pitamin were significantly higher than those of the control group (p<0.05). Taken together, these results suggest that providing hens with a diet supplemented with 0.1% pitamin as a organic livestock feed additives may extend the shelf-life of eggs with maintaining the egg quality and egg production in laying hens.

  • The microstructure of Watts and bright ni-ckel electrodepositss is correlated with pref-erred orientation. The characteristics lamellar structure of bright nickel was atributed to the periodic adsorption of organic additives and related to cyclic fluctuations in temper-ature.
