石蜡全称为石油蜡,它是石油炼制过程中的副产品。石蜡可分为液体石蜡、固体石蜡、微晶蜡、凡士林等产品。蜡其实不是什么新鲜的东西,人类应用蜡的历史其实非常久远。在石油蜡没有大规模出现前,其来源主要有动物蜡和植物蜡两个方面。如我国的蜂蜡就是蜜蜂科分泌的蜡质经加工而成蜂蜡。直到大规模开采石油,提炼出石油蜡之后,蜡才得到广泛应用。
Paraffin wax is known as petroleum wax. It is a byproduct of petroleum refining. Paraffin wax can be divided into liquid paraffin, solid paraffin, microcrystalline wax, vaseline and so on. Wax is not something new. The history of human wax is very long. Before the large-scale emergence of petroleum wax, there were two main sources of animal wax and animal wax. In China, beeswax is the wax produced by the honeybee family and processed into wax. Wax was not widely used until large scale oil was extracted and petroleum wax was extracted.
石蜡具有广泛的用途,如汽车防护防腐、炸药生产、板材生产、印刷油墨、日化产品和果蔬保鲜等。石蜡在食品行业中也有很多用途。我国食品添加剂标准GB2760中规定,石蜡可以作为食品加工助剂使用于薯片、油脂、糖果及粮食加工中,主要做消泡剂或者脱模剂使用;石蜡还可以作为胶基糖果中的基础剂物质,另外,石蜡也可以作为被膜剂用于鲜鸡蛋表面,有防虫防灰的作用。在食品包装中,石蜡可用于与食品接触的容器、包装材料的浸渍用蜡,主要起防水的作用。不过,石蜡并不允许直接用在食品中。
Paraffin wax has a wide range of uses, such as automotive protection and anti-corrosion, explosive production, plate production, printing ink, daily chemical products and fruit and vegetable preservation. Paraffin wax also has many uses in the food industry. In our food additive standard GB2760, paraffin can be used as a food processing agent in potato chips, oil, candy and grain processing, mainly used as defoaming agent or demoulding agent. Paraffin can also be used as a basic agent in gum based candy. In addition, paraffin can also be used as a membrane agent for the surface of fresh eggs. It has the effect of insect proof and ash prevention. In food packaging, paraffin wax can be used for impregnating wax for containers and packaging materials that are in contact with food. However, paraffin wax is not allowed to be used directly in food.
