Problems solved by technology

However, because TBHQ has great side effects and harm to the human body, many countries including Japan and many instant noodle companies currently prohibit the use of TBHQ
Antioxidants have a good effect on preventing the oxidative rancidity of general oils and fats, but the heat resistance of general antioxidants is poor; after heating, especially at high temperatures such as frying, it is easy to be decomposed or volatilized
Adding other natural antioxidants has problems such as high addition amount, high cost, poor flavor, dark color, and insignificant effect.
[0005] Although the prior art has conducted research on the antioxidant properties of fats and oils, no solutions have been proposed for the stability, shelf life, and flavor of fried foods.
Judging from the technical solutions disclosed in the prior art, it is also impossible to completely solve the problems of food shelf life and flavor.
[0006] CN102422903A uses tertiary butyl hydroquinone, ascorbyl palmitate, and polydimethylsiloxane emulsion to improve the stability of frying oil, but it cannot prolong the shelf life of food, nor can it obviously inhibit the flavor change in food storage
However, these methods cannot improve the quality of frying oil, and it is difficult to effectively inhibit the oxidation of the oil on the surface of fried food.

Embodiment 1-17

[0081] Take 3000 grams of soybean oil, add different components respectively according to the ratio in the table below, and obtain a frying oil sample after homogenization. Set the temperature of the frying oil (130-180°C) to carry out the frying experiment. Each batch fried 3 pieces of noodle cakes, each piece of instant noodle cakes was 40 grams, and the frying time was 55 seconds. A total of 40 batches were fried. The last batch of 3 noodle cakes were retained as samples for oil absorption testing and accelerated oven testing at 55°C. The accelerated test samples were subjected to sensory evaluation and oil routine index testing.

[0082]

[0083]

[0084] Stability Evaluation:

[0085] Take out the sample after six weeks of accelerated test in a 55°C oven, weigh about 100g of the broken and evenly mixed instant noodle sample, put it in a 500ml conical flask with a stopper, add 100-200ml of n-hexane, let it stand overnight, and filter it with fast filter paper Final...

Embodiment 22-25

[0110] With reference to Example 17 or 18, the noodle cakes are replaced with French fries, deep-fried dough sticks, doughnuts, and chicken wings respectively, and the specific scheme is as follows:

[0111]

[0112]

[0113] Through oven acceleration test, AV, PV, sensory evaluation, and detection of oil content, it is found that adopting the technical scheme of the present invention can well suppress the increase of AV and PV, effectively prolonging the shelf life of food; meanwhile, through sensory evaluation, it can also It is found that the flavor of the relevant food is well maintained during storage, effectively suppressing the deterioration of the flavor during storage; in addition, it can also be found through the detection of oil absorption rate that the oil content of the relevant food is significantly higher than that of the solutions in the prior art. The reduction effectively inhibits the oil absorption rate of food.

Abstract

The invention provides an oil additive composition. The oil additive composition contains an antioxidant, squalene, phytic acid or a salt thereof, and polydimethylsiloxane. The oil additive composition can substantially prolong the shelf life of the foods, inhibit flavor change in the storage process of the foods and reduce the food oil absorbency. The invention also provides an oil composition containing the oil additive composition.

Description

technical field [0001] The invention relates to a fat composition, in particular to a frying oil composition. Background technique [0002] During storage, processing and circulation, the oil components in food are susceptible to oxidation by oxygen in the air, causing discoloration or odor and generating harmful substances, especially oil and fat-rich foods are often rancid due to oxidation. Adding antioxidants can prevent food components from oxidative deterioration. For nearly half a century, in order to prevent the oxidation of oils, people have studied the antioxidant problems of oils from different angles. Adding antioxidants to oils and fat-rich foods has become a food product. The most economical and simple method to prevent food from oxidative deterioration during processing. At present, the use of antioxidants in our country is not widespread, only some applications in the imported food manufacturing technology, but basically it is a single antioxidant, and most o...
