[0004] Invention patent CN103271253B discloses an inhibitor for inhibiting the production of acrylamide when frying potato chips and its usage. The scheme uses blueberry anthocyanin, vitamin C and citric acid to make a composite antioxidant as an inhibitor for inhibiting the production of acrylamide, but Blueberry anthocyanins are very unstable and sensitive to pH, temperature and light. They need to be stored and used under acidic conditions of pH<3. The stability will decrease with the increase of pH. When the pH is 5.0, the preservation rate is only 48%. %, the preparation of inhibitors in this scheme is more complicated, and it only has an inhibitory effect on the acrylamide generated, but there are other harmful substances produced in the Maillard reaction, such as: methylglyoxal and glyoxal, this scheme does not reach While inhibiting the production of acrylamide, reduce the production of other harmful substances
[0005] Invention patent CN106473057A discloses a method for preparing low-acrylamide garlic-flavored French fries. In this scheme, potato strips are soaked in garlic extract and then fried to reduce the content of acrylamide. taste, the scope of application is narrow, and cannot be widely promoted
[0006] Invention patent CN105831549A discloses the natural composite antioxidant of bean dregs extract and its preparation method. In this scheme, the composite antioxidant is composed of bean dregs extract, tea polyphenols, lecithin, vitamin C, citric acid and glycine. However, in this scheme, the bean dregs extract Natural composite antioxidants have complex components and low applicability
[0007] Therefore, from the perspectives of the practicality of the method, the requirements of food for color, fragrance and food safety, many methods for inhibiting acrylamide are difficult to meet the actual needs, and the harmful products in the middle stage of the Maillard reaction are not carried out. Therefore, new methods to reduce the formation of acrylamide while maintaining the original flavor and texture of the food have yet to be explored

Embodiment 1

[0050]The method of reducing the content of acrylamide in fried dough sticks: add appropriate amount of salt and baking powder to the flour for making deep-fried dough sticks, and add different amounts of inhibitors, namely 0.01g / kg, 0.1g / kg, 1.0g / kg, 2.5g / kg kg, 4.0g / kg, 5.0g / kg, set as six test groups and one blank control group, then add water to the flour, stir until it becomes cotton wool, knead it into a dough, let it stand for 1 hour, knead the dough again until smooth, And apply a layer of oil on the surface of the dough, seal it with plastic wrap and let it stand for 1 hour again, spread the fermented dough into long strips and cut into small strips, deep-fry the long strips in the pan until golden brown, remove and drain the oil, each The test group all used new oil, the oil temperature was 130-140°C, and the frying time was 2 minutes.

[0051] The weight ratio of okara extract to phlorizin in the inhibitor is 2:1.

[0052] After the samples were pretreated, the con...

Embodiment 2

[0058] The method to reduce the content of acrylamide in fried potato chips: Peel and slice fresh potatoes, soak them in water for 5 minutes, drain them, and prepare inhibitor aqueous solutions with different concentrations, the concentrations are 0.01g / L, 0.1g / L, 1.0g respectively / L, 2.5g / L, 4.0g / L, 5.0g / L, set up as six test groups and a blank control group, soak the potato slices in the inhibitor aqueous solution for 20min, take out and drain, wait until the oil temperature reaches 130 ~140°C, put the potato slices into the pot, and the surface of the potato slices will turn golden yellow in 2-3 minutes, remove and drain the oil, and use new oil for each test group.

[0059] The weight ratio of okara extract to phlorizin in the inhibitor is 4:1.

[0060] After the samples were pretreated, the content of acrylamide was determined by high performance liquid chromatography (Table 2).

Abstract

The invention provides a method for reducing the content of acrylamide in fried food. The method specifically comprises the steps that a soybean residue extract and phlorizin are prepared into a composite inhibitor with the appropriate ratio, the inhibitor is added into different food raw materials, by controlling the processing time, frying temperature and drying time, the effects that maillard reaction intermediate harmful substances can be reduced, and meanwhile the generation of the acrylamide is inhibited are finally achieved, and the soybean residue extract and the phlorizin are correspondingly obtained by extracting from fresh soybean residues, rhizome, bark, pericarp and leaves of apples and pears. According to the method for reducing the content of acrylamide in the fried food, raw materials are cheap and easy to obtain, the performance is stable, the effects of regulating blood sugar and blood pressure, allergy resistance and cardio cerebrovascular disease resistance are achieved, high health care value is achieved, the practicability is high, eating is safe, and the original flavor of the food is retained.

Description

technical field [0001] The invention belongs to the technical field of food safety production, and in particular relates to a method for reducing the content of acrylamide in fried food. Background technique [0002] Fried food is one of the traditional foods in our country. It is deeply loved by people because of its crispness, delicious aroma, and ability to increase appetite. However, regular consumption of fried food is extremely harmful to health, because fried food is processed at high temperature Maillard reaction will occur in the fried food, although this reaction gives fried food an attractive brown color and unique flavor, it also produces acrylamide, a substance that has been listed as a possible carcinogen by the WHO International Cancer Research Center (IRAC). Today, with increasing emphasis on health and safety, how to reduce the content of acrylamide in food without affecting the flavor of food has become a hot issue of concern to consumers. [0003] There a...
