Abstract:The aim of this study was to investigate the effect of chinese medicinal herb extract on the spinach fresh-keeping For this,the material liquid ratio of 1:10 extracting solutions were prepared and its effect on the spinach quality was investigated.The formulations were based on licorice,hance ginger and its complex extract.Spinach were subjected to a treatment by dipping in these extracts for 5 min,and with the distilled water as a control.All products were stored at(3±1)℃ and the quality parameters such as sensory evaluation,decay rate,weight lose,respiration rate,total acid content,Vc content and chlorophyll content were evaluated.The effects of different treatments on the keeping fresh quality of spinach were investigated.The results showed that all chinese medicinal herb extracts could improve the sensory quality,decrease the decay rate,inhibit the respiratory intensity and weight loss,delaying of the decline of titratable acidity,vitamin C and chlorophyll contents.It has been proven that the material liquid ratio of 1:10 complex extract significantly(P<0.05) improve the fresh-keeping effects of spinach compared with that of the control.
