摘要
Abstract
Antimicrobial activities of maize (Zea mays. L.) silks extracted with organic solvents were tested against seven food spoilage and food-borne pathogens for the first time.Ethanol (95%,v/v) extracts were ascertained to be the optimum by permitting the maximum yield and the highest antimicrobial activity.The MICs (minimum inhibition concentrations,in g/100g) of maize silk extracts were determined as 1.5 against Escherichia coli,3.0 against Staphylococcus aureus,3.0 against Pseudomonas fluorescens,1.5 against Salmonella typhimurium,2.0 against Bacillus subtilis,2.5 against Bacillus cereus,and 2.0 against Proteus vulgaris,respectively.Influences of food properties including mid-range pH values,storage temperature and time on the activities of the maize extracts were examined.The dependence of the activity on routine food sterilization conditions was measured as well.Therefore,the maize silk extracts could serve as potent,safe and effective food preservatives by means of controlling food properties and processing conditions.关键词
