Problems solved by technology

The disadvantages of endogenous ingredients include weak antioxidant activity, poor thermal stability, and easy loss during oil processing. For example, tocopherol has poor thermal stability and is mainly lost through oxidation and thermal degradation during high-temperature frying. Sesame Phenol is

Embodiment 1

[0037] According to the formula of table 1, prepare compound antioxidant, comprise the steps:

[0038] (1) Weighing the rosemary extract, adding it to soybean oil, stirring continuously at 85° C. until it dissolves completely, filtering, and discarding the filter residue to obtain an oil phase;

[0039] (2) Weighing tea polyphenols, rattan tea extract, ascorbyl palmitate and vitamin C microcapsules, adding them to edible ethanol, and stirring continuously at 55°C until uniformly dispersed to obtain a premix;

[0040] (3) Slowly add the premix obtained in step (2) into the oil phase, keep stirring at 55°C, and mix thoroughly for 40 minutes.

Embodiment 2

[0042] Same as Example 1, the only difference is that the formula is different, see Table 1.

Embodiment 3

[0044] Same as Example 1, the only difference is that the formula is different, see Table 1.

Abstract

The invention discloses a compound antioxidant for improving the stability of frying oil and fried food and a preparation method thereof. Through the synergistic effect of all substances of a main antioxidant and the synergistic effect of an auxiliary antioxidant, the increase of acid value, polar components and carbonyl value caused by thermal oxidation reaction in the frying oil can be inhibited, and the growth of the polar component caused by the polymerization reaction is also inhibited; and the peroxide value and the malondialdehyde content increase rate during the storage process of the fried food are reduced, the generation of the peculiar smell such as rancidity is inhibited, the oxidation stability of the frying oil can be effectively improved, and the antioxidant effect can be continuously performed in the fried food along with the carrying of the oil so as to prolong the shelf life of the fried food.

Description

technical field [0001] The invention belongs to the technical field of anti-oxidation for high-temperature frying of food, and in particular relates to a compound antioxidant for improving the stability of frying oil and fried food and a preparation method thereof. Background technique [0002] Frying is a very complex and very important operation unit, which is widely used in food industry, catering industry and home cooking. Fried food under the right conditions has an attractive flavor, golden surface and crispy texture and taste, so it is deeply loved by consumers. But when the frying temperature is too high and the time is too long, the frying oil will undergo various physical and chemical changes, and penetrate into the food to become its constituents, which will affect the quality and nutritional value of the food. The quality of frying oil will directly affect the quality and safety of fried food and the health of consumers. The main products of oil and fat during ...
