Storage and management: The place for walnut storage should be cool and dry. A rodent-free place. In the past, most of them were stored in sacks, mats or round piles. During storage, ventilation and cooling were required. However, once the management is slightly poor, it will easily cause rancidity (commonly known as hala) or cheese, thereby reducing the quality of walnut storage. In recent years, with the development of controlled atmosphere food storage, many units now use plastic film tents or seals to store walnuts, and the effect of walnuts is very good.
Because dry walnuts that have been dormant for a long time have low water content and high oil content, their respiration is very weak, and they consume very little oxygen. Storage in a higher concentration of carbon dioxide can further inhibit the respiration of the fruit, thus Reduce consumption, and fungal diseases that cause fruit rot will also be suppressed under conditions of hypoxia and high concentrations of carbon dioxide. In addition, the oil contained in walnuts is not easily oxidized in a low-oxygen environment, causing rancidity or cheese formation. Therefore, in addition to sealing walnuts with plastic film tents to naturally reduce oxygen, you can also use the method of filling carbon dioxide gas to increase the carbon dioxide concentration in the tents to above, which can further increase the storage effect. In the presence of high concentrations of carbon dioxide, many warehouse pests cannot grow, so pests in walnuts during storage can also be eliminated. Similarly, if the method of nitrogen filling and oxygen reduction is used to store walnuts, similar storage effects can be achieved, which is worthy of promotion.
