冬化脫蠟是將油脂冷卻使油脂中凝固點較高蠟質結晶析出的過程。葵花籽油、玉米胚芽油、米糠油等含蠟質較高的油品經脫膠、脫酸、脫色、脫臭等精煉工序后, 在氣溫較低的冬季仍會有少量固體脂呈絮狀沉淀析出,影響油品的外觀和使用,為了杜絕這種現象,這些油品需增加冬化脫蠟加工工序。冬化脫蠟在緩慢地攪拌下,在一定時間內將油脂冷卻至4-6℃左右,使蠟質形成較大結晶,并分離析出,再經過濾,將液態油和固體脂肪分離開,從而提高了油脂的食用品質及營養價值。
Winterization dewaxing is a process of crystallization of wax with high freezing point by cooling oil. For sunflower oil, corn germ oil and rice bran oil with high wax, after degumming, deacidifying, decolorization, deodorization and other refining processes, a small amount of solid fat will be flocculent precipitation in cold winter, and affect the appearance and use of the product. In order to put an end to this phenomenon, these products need to increase the process of winterization dewaxing. Under stirring slowly, winterization dewaxing will cool the oil and fat to around 4-6 ℃ in a certain period of time, and the wax forms a larger crystal, separation and precipitation, then through filtering, the liquid oil and solid fat separation, thus improve the edible quality and nutritional value of the oil and fat.
