  • Two antimicrobial extracts of Rheum palmatum L. and Coptis chinesis France root as well as grapefruit seed extract(GFSE) were applied to dipping treatment for green chilli peppers, which were then packed in low density polyethylene(LDPE) films incorporated with 1% antimicrobial extracts and stored 10$^{\circ}C$. Dipping and packaging treatments suppressed the growth of putrefactive microorganisms and the duly ratio of green chilli peppers. In addition, the loss ratio of ascorbic acid content and their weight during the storage was lower with treated green chilli peppers. Consequently, the combined method of dipping and packaging in antimicrobial agents turned out to be superior to dipping treatment or film-packaging in the view point of decay ratio and the keeping qualities of green chilli peppers.

  • This study was carried out to clarify effects of field location and sprayer on the level of pesticide residue in chilli peppers. As confirmed by statistical analysis, the residue levels in green pepper among three greenhouses did not show significant difference at the first day after spraying with the same engine sprayer and nozzle. But the residue levels in green peppers collected from the exposed outside of crop were 2 times higher than those from the hidden inside. The sampling site was one of variation elements of pesticide residue. The residue levels after application by knapsack engine powered sprayer were 1.7 times higher than those by manual compressed sprayer. As the spraying pressure of the engine power sprayer is 2 times higher than the commonly used pressure of the manual compressed sprayer, the pressure of the sprayer and nozzles were considered to affect on the residue levels in peppers.
