主　　题：Lettuce Modified Atmosphere Packaging (MAP) Postharvest Quality 

摘      要：Lettuce is a perishable vegetable that its shelf life is limited by detrimental texture changes and enzymatic activities during postharvest *** of solutions that can be used in storage and distribution of this product is modified atmosphere packaging(MAP).But its effects on the mechanical properties of the product have not been *** information would be beneficial in inspection of eating quality and later processing such as cutting and *** research aimed to study effect of active MAP technology on the postharvest mechanical properties of lettuce at different storage *** was found that MAP had a significant effect on the tension property of the lettuce *** treatment preserved the brittleness of the specimens during storage,but the control ones lost their brittleness and tolerated greater *** and rupture energy were significantly affected by MAP with P values of 0.01 and 0.05,***,stiffness of the MAPtreated samples was higher than the control at the same storage *** findings are due to reducing respiration,transpiration and bacterial growth by MAP which delays nutrient decomposition and maintains the original color and texture.
