Vacuum Packaging Machine: Technical Features of Rice Vacuum Packaging Machine
Rice still has vitality (enzymatic activity) after harvest, and its quality gradually decays during storage. Therefore, there is so-called new rice and old rice. Due to the problem of oil oxidation during storage, the taste and aroma of new rice is generally better than that of old rice. Also, the old rice is yellowish in color and less transparent
The shelf life of rice varies according to its processing method, packaging method, etc. Ordinary packaging may only be 6-12 months; the shelf life of bulk rice is not clearly specified, generally 3 months in summer and 6 months in autumn and winter. In the case of bulk, the spring and summer are humid and hot, and the shelf life of rice with large moisture is only 3 months.
So, how many months is the shelf life of vacuum packaging?
The shelf life of vacuum-packed rice can reach 12-18 months, and the quality of the rice is also good. After opening the bag, it retains the sweet taste of new rice. Therefore, for high-end quality rice, manufacturers often use vacuum-packed rice for consideration of the quality of the rice. Way. However, since it is difficult for vacuum packaging to completely maintain a vacuum during packaging, transportation, and storage, and the cost of maintaining a vacuum state is high, the market price is relatively high. This packaging method is often only suitable for high-end new rice.
