Embodiment 1

[0020] Antioxidants are: Blueberry Anthocyanins.

[0021] Blueberry anthocyanins with a purity of 7% were prepared into a 0.5% dipping solution for later use.

[0022] The specific usage method is:

[0023] Wash the potatoes, peel them, and use a plane to prepare potato chips with a uniform thickness of 2mm, then cut them into 3.5×2.0cm size with a blade, rinse with water to remove free starch, and blanch them in hot water at 85°C for 3.5min. After soaking for 30 minutes, dry in a 60°C oven for 15 minutes; then fry at 130°C until puffy, drain off the oil, and cool to obtain the product.

[0024] The average content of acrylamide in the obtained product was 2.54 μg / kg (n=3). And it was 7.29 μg / kg (n=3) when treated with clean water.

Embodiment 2

[0026] Antioxidants are: Blueberry anthocyanins (7% purity) and vitamin C 5:1 mixture.

[0027] Prepare the above mixture into a 0.3% dipping solution for later use.

[0028] The specific usage method is:

[0029] Wash the potatoes, peel them, and use a plane to prepare potato chips with a uniform thickness of 2mm, then cut them into 3.5×2.0cm size with a blade, rinse with water to remove free starch, and blanch them in hot water at 85°C for 3.5min. After soaking for 30 minutes, dry in a 60°C oven for 15 minutes; then fry at 130°C until puffy, drain off the oil, and cool to obtain the product.

[0030] The average content of acrylamide in the obtained product was 2.01 μg / kg (n=3). And it was 7.29 μg / kg (n=3) when treated with clean water.

Embodiment 3

[0032] Antioxidants are: Blueberry anthocyanins: citric acid: vitamin C is a 5:1:1 mixture.

[0033] Prepare the above mixture into a 0.5% dipping solution for later use.

[0034] The specific usage method is:

[0035] Wash the potatoes, peel them, and use a plane to prepare potato chips with a uniform thickness of 2mm, then cut them into 3.5×2.0cm size with a blade, rinse with water to remove free starch, and blanch them in hot water at 85°C for 3.5min. After soaking for 30 minutes, dry in a 60°C oven for 15 minutes; then fry at 130°C until puffy, drain off the oil, and cool to obtain the product.

[0036] The average content of acrylamide in the obtained product was 1.47 μg / kg (n=3). And it was 7.29 μg / kg (n=3) when treated with clean water.

Abstract

The invention relates to an inhibitor for inhibiting generation of acrylamide in a potato frying process and a use method of the inhibitor, and belongs to the technical field of food science. Aiming at the problem that toxic acrylamide is easily generated by crisp potato chips under high-temperature frying conditions, a food safety single or compound antioxidant taking blueberry anthocyanins as main components is screened out for inhibiting generation of acrylamide through an antioxidant mechanism. The technology has a good effect of inhibiting generation of acrylamide, achieves the purpose of integrating various nutritional substances, and has a good market prospect.

Description

technical field [0001] This research relates to the field of food science and technology, specifically an inhibitor of acrylamide production during frying potatoes and its application method. Background technique [0002] Fried potato chips are a kind of snack food, which has the characteristics of delicious flavor and portability, and is favored by more and more consumers. But scientists have discovered that acrylamide will be produced when potato chips and strips are fried at high temperature. Acrylamide, commonly known as poison C, can cause human nerve damage and reproductive toxicity, and can cause animal deformation and carcinogenesis. It is a potential carcinogen for humans. Today, with increasing emphasis on health and safety, how to reduce the content of acrylamide in potato chips while improving the color and quality of potato chips is an important issue to promote the development of potato processing and its industrialization. According to Mottyam and Stadler, t...
