The postharvest treatment of fruits and vegetables with glycine betaine offers several benefits that help maintain the quality and extend the shelf life of these perishable products. Here are some of the key roles of glycine betaine in postharvest treatments:
Reduces Dehydration: Glycine betaine acts as an osmoprotectant, meaning it helps cells retain water. When applied to fruits and vegetables, it helps prevent excessive water loss through transpiration and evaporation, reducing dehydration. This is especially important for produce with thin skins or high surface area-to-volume ratios, which are more susceptible to water loss.
Delays Senescence: Senescence refers to the natural aging process of fruits and vegetables, during which they undergo biochemical and physiological changes that lead to softening, color changes, and loss of nutritional value. Glycine betaine has been shown to slow down the senescence process, delaying the onset of undesirable changes and preserving the visual appeal and quality of the produce for a longer time.
Maintains Cellular Integrity:
Glycine betaine helps stabilize cellular structures in fruits and vegetables. It protects cellular proteins and membranes, reducing cell damage and maintaining the structural integrity of the tissues. This results in firmer and less prone-to-bruising produce.
Reduces Spoilage and Decay: By preserving the quality of fruits and vegetables, glycine betaine postharvest treatment helps reduce spoilage and decay. Slowing down the aging process and maintaining cellular integrity contribute to a longer shelf life, reducing the likelihood of premature spoilage.
Retains Nutritional Value: The application of glycine betaine can help preserve the nutritional content of fruits and vegetables, such as vitamins, minerals, and antioxidants. By delaying senescence and reducing deterioration, the produce retains its nutritional value for a longer period, benefiting consumers with fresher and healthier options.
Enhances Transportation and Marketability: Improved shelf life and reduced spoilage due to glycine betaine treatment facilitate better transportation and handling of fruits and vegetables. Produce can be transported over longer distances without significant quality losses, allowing access to a wider market and reducing food waste.
Environmental Stress Tolerance: Fruits and vegetables may undergo various stresses during postharvest handling, such as temperature fluctuations and physical damage. Glycine betaine can help protect them from these stresses, ensuring better quality and appearance upon reaching consumers.
