Description

Technical Field

[0001] The present application relates to the field of oils and fats, and specifically relates to a frying oil composition and a preparation method thereof. Background Art

[0002] Frying is a traditional cooking method. Due to its high temperature and fast cooking speed, it can produce a golden appearance and a crispy texture, and is widely used around the world. The frying process is very complex. Along with the gradual oxidation of the oil, food residues fall into the frying oil, and the Maillard reaction occurs between the oil and proteins to produce flavor substances. In the middle and late stages of frying, these components will condense on the bottom of the pot, around the pot, and around the heating tube to form a layer of dirt, which affects the heat conduction of the heating tube, causing uneven local heating. The dirt around the heating tube will also carbonize and turn black due to excessive temperature, deepening the color of the heating oil, making the frying oil have too strong a smoky and burnt smell, which affects the flavor of the food, seriously reducing the frying performance of the frying oil. At the same time, the accumulation of dirt around the pot will also cause difficulties in cleaning. Some customers, in order to prevent the influence of scale formation on the heating system, clean the dirt during frying, drain the high-temperature hot oil from the frying pan, continue frying after cleaning without dirt, which is time-consuming and laborious, and has potential safety hazards.

[0003] Currently, the research on frying oil mainly focuses on improving the frying stability of the oil. By adding exogenous substances to enhance the thermal stability of the frying oil and inhibit the increase of acid value, polar components, and color, while ignoring the influence of dirt on the frying oil during the frying process.

[0004] CN201310025232.8 records a method for reducing polymers generated during frying of frying oil, which inhibits the increase of polar components by adding sesamol substances.

[0005] CN201910223123.4 records a composite frying oil and a method for improving the oxidation stability of frying oil during frying. By adding a certain proportion of seabuckthorn oil to enhance the thermal stability of the frying oil and inhibit the increase of physicochemical indexes such as acid value and polar components.

[0006] There is no relevant information and literature on how to inhibit the aggregation of impurities on the frying pan and the heating tube. Summary of the Invention
