Abstract:
      n order to solve the problem of degradation of the quality of edible oil due to various changes that occur during the storage process, a fresh-keeping production technology of edible oil was introduced, including constant temperature filling in the whole section, nitrogen filling and UV resistant bottle packaging. The practice showed that the constant temperature filling in the whole section could effectively avoid the bottle shrinkage caused by the high filling oil temperature and negative pressure, and reduce the occurrence of uneven labels. Nitrogen filling could make the residual oxygen content in the processed edible oil bottle less than 6%, and the product residual oxygen index stable. The food grade edible oil packaging bottle made of color masterbatch as an anti-ultraviolet additive could prevent the influence of ultraviolet rays on the quality of edible oil. The use of this production process can effectively improve the quality of edible oil and extend the storage period.
