Shelf-life extending of jasmine garland

摘要

In Thailand, jasmine flower is consumed as a fresh jasmine garland. Demand of jasmine flower is high throughout the year. However, marketing of jasmine garland is limited due to a short shelf-life. Therefore, effectiveness of boric acid and benzyladenine on shelf-life extending were studied. Jasmine flower buds were treated with benzyladenine or boric acid at concentrations of 0,100, 500 and 1,000 mg L1 for 15 min before completion of garlands. The results showed that both benzyladenine and boric acid could reduce respiration and weight loss. Moreover, both chemicals also gave good effects on extending shelf-life. In addition, pre-treated garlands packed in PP and PE bag were compared. PP bag could maintain quality of jasmine garlands better than PEbag. These indicated that application of 500 mg L 1 benzyladenine or boric acid combined with packing in PP bag could extend shelf-life of jasmine garland to 10 days.
