Study on hypobaric storage of green asparagus

The effects of hypobaric storage on the biological characteristics of green asparagus were compared against refrigeration and room temperature storage. Hypobaric storage significantly (P ⩽ 0.05) inhibited the respiratory intensity, preserved chlorophyll, vitamin C, titratable acidity and soluble solids, and also reduced MDA accumulation in asparagus. Hypobaric storage obviously improved sensory quality, delayed the post-harvest senescence process of asparagus. It extended the storage life up to 50 days, whereas refrigerated and room temperature stored samples exhibited only 25 and 6 days, respectively.
