书  Book
各种油品材料，在工农业生产及日常生活中应用非常广泛。从可食性 的角度来分， 分为食用油和非食用油， 它们在高温环境下， 均有可能被严 重氧化。特别是食用油， 和身体健康息息相关。但食用油在普通锅中使用 时，油在高温下会和空气中的氧气反应形成过氧化物，或通过二聚体形成 高聚物， 导致油的粘度升高； 当食物放入粘度升高的食用油中， 将产生大 量细小且不易破裂的气泡，并且在此过程中生成有害的环状聚合物。同时 油粘度的升高，将大大降低油的导热效率，从而使食品在加工过程中饱含 大量的油，使食物有油腻感并大大降低油炸食物的口味，从而使最终油炸 的食物不酥脆， 口味不鲜美。 另外， 工业用油为非食用油， 比如在机床行 业大量使用的机床油，会因机械加工工程中产生大量的热，造成机床油逐 歩被氧化、 变质， 而氧化、 变质后的机床油， 可能会被废弃掉。 这不但造 成了机床油的浪费，也是造成环境污染的重大隐患。如何降低油品成分的 氧化程度、 减缓氧化过程， 是目前的一个重大课题。 【发明内容】 Various oil materials are widely used in industrial and agricultural production and daily life. From the perspective of edibleness, it is divided into edible oils and non-edible oils, which may be severely oxidized in high temperature environments. In particular, cooking oil is closely related to physical health. However, when the edible oil is used in a common pot, the oil reacts with oxygen in the air to form a peroxide at a high temperature, or forms a high polymer by a dimer, resulting in an increase in the viscosity of the oil; In the edible oil, a large number of fine and non-rupturing bubbles are generated, and a harmful cyclic polymer is formed in the process. At the same time, the increase of oil viscosity will greatly reduce the heat transfer efficiency of the oil, so that the food is rich in oil during the processing, making the food greasy and greatly reducing the taste of the fried food, so that the final fried food is not crispy. The taste is not delicious. In addition, industrial oils are non-edible oils. For example, machine tool oils that are used in large quantities in the machine tool industry will cause a large amount of heat in the machining process, causing the machine tool oil to be oxidized and deteriorated, and the oxidized and degraded machine tool oil. May be discarded. This not only causes waste of machine tool oil, but also a major hidden danger of environmental pollution. How to reduce the oxidation degree of oil components and slow down the oxidation process is a major issue at present. [Summary of the Invention]
