Background

Tea oil, also known as Camellia oil and Camellia seed oil, is pure natural high-grade edible plant oil extracted from the mature seeds of common Camellia oleifera (Camellia oleifera Abel) of Camellia plants in the family of theaceae, and has golden or light yellow color, pure quality, clarity, transparency, fragrant smell and pure taste. The tea oil is used as edible oil, the quality guarantee period of the tea oil is different according to the preservation mode of the tea oil, the common deterioration mode is tea oil rancidity, the main reason of the tea oil rancidity is that the tea oil rancidity is contacted with oxygen in the air, unsaturated fatty acid in the oil is subjected to oxidation reaction, and the tea oil loses edible value; the current fresh-keeping mode can also keep fresh through nitrogen gas to injecting into the oil bottle, keeps fresh tea-seed oil through nitrogen gas, but gaseous nitrogen gas because volatility is very fast, has most nitrogen gas volatilization at the in-process of grease filling and gland, has reduced the concentration of nitrogen gas in the packing bottle, can't realize fresh-keeping efficiency. Therefore, the technical process of the invention adopts the method of adding high-concentration liquid nitrogen into the packaged oil bottle to reduce the concentration of oxygen, which not only can reduce the contact between the oil and the oxygen, thereby achieving the purpose of oxidation resistance of the oil, but also can improve the shelf life of the product.

In summary, the preservation of edible package oil generally requires the addition of antioxidant or the preservation with gaseous nitrogen, the former method cannot achieve the safe and natural preservation method pursued by consumers at present, and the latter method is very difficult to ensure the effect in the actual production operation because the volatility of gaseous nitrogen is very fast.
