This study aims to investigate the postharvest physiology and texture of garlic cloves packaged in polyethylene terephthalate (PET), polyethylene (PE), aluminized kraft paper (AKP), single kraft paper (SKP), and mesh bag. Germination rate, electrical conductivity, respiration intensity, water content, and texture were determined during 180 d storage at -2 °C. Results showed that the germination of garlic cloves packaged in PET, PE, and AKP was effectively inhibited during storage. PE effectively reduced the degree of damage to the cell membranes of the garlic cloves. PE and SKP significantly inhibited respiratory intensity during storage. Garlic cloves water content did not change significantly in 90 d storage which packaged in PE and SKP. PE exhibited better effect on the texture and freshness of garlic cloves than the other materials. In conclusion, PE is the best packaging material for maintaining the quality attributes and extending the shelf lives of garlic cloves.
本研究旨在探究用聚对苯二甲酸乙二醇酯(PET)、聚乙烯(PE)、镀铝牛皮纸(AKP)、单牛皮纸(SKP)和网眼袋包装的大蒜蒜瓣的贮藏后生理和质地特性。在-2°C下贮藏 180 天期间,测定了发芽率、电导率、呼吸强度、含水量和质地。结果表明,在贮藏过程中,用 PET、PE 和 AKP 包装的大蒜蒜瓣的发芽得到了有效抑制。PE 有效地降低了大蒜蒜瓣细胞膜的损伤程度。PE 和 SKP 在贮藏过程中显著抑制了呼吸强度。在 90 天的贮藏期内,PE 和 SKP 包装的大蒜蒜瓣含水量没有明显变化。PE 对大蒜蒜瓣的质地和新鲜度的保持效果优于其他材料。综上所述,PE 是保持大蒜蒜瓣品质属性和延长货架期的最佳包装材料。
