Embodiment 1

[0018] Raw materials: 1000 grams of fresh sweet potatoes, 300 μg of sodium selenite.

[0019] Preparation method: Wash the sweet potatoes, peel them, cut them into 6mm thick round slices by machine or manually, and set aside.

[0020] Put the above-mentioned processed sweet potato slices into a blanching machine, raise the temperature to 90°C, and after 5 minutes, take out the sweet potatoes and put them into cold water, and the blanching is over.

[0021] Drain the above-mentioned blanched sweet potatoes and put them into an open oven for drying at 65°C. After about 2.5 hours, the water content of the sweet potatoes will be 20%-40%.

[0022] Preparation of selenium source nutrient solution: while the semi-dry tablet is cooling, dissolve 300 μg of sodium selenite in 20 g of water, and set aside after dissolving.

[0023] After the semi-dry sweet potato slices soften, add the selenium source nutrient solution prepared above, mix well, let stand for 0.5h, then put it into a pre...

Embodiment 2

[0026] Raw materials: 1000 grams of sweet potato, 400 μg of sodium selenite.

[0027] After washing the sweet potatoes, peel them by hand, and cut them into 6mm thick round slices by machine or by hand.

[0028] Drain the above-mentioned processed sweet potatoes and put them into a blanching machine, raise the temperature to 80°C, and after 9 minutes, take out the sweet potatoes and put them into cold water, and the blanching is over.

[0029] Drain the above-mentioned blanched sweet potatoes and put them into an open oven for drying. The drying temperature is 55°C. After about 4 hours, the water content of the sweet potatoes will be 20%-40%. At this time, stop heating and soften for 24 hours after cooling.

[0030] Preparation of selenium source nutrient solution: while the semi-dry tablet is cooling, dissolve 400 μg of sodium selenite in 20 g of water, and set aside after dissolving.

[0031] After the semi-dry sweet potato slices have softened, add the prepared selenium so...

Abstract

The invention relates to a preparation method of selenium rich sweet potato flakes, and belongs to the technical field of health food. The selenium rich sweet potato flakes are prepared by using fresh sweet potato and sodium selenite as raw materials. The method comprises the following steps of: 1) cleaning and slicing; 2) blanching; 3) preparing semi-dry flakes; 4) preparing selenium source nutrient solution; 5) puffing; and 6) thermal drying. The method has the advantages that: because the selenium element is added into the sweet potato food, trace selenium element required by the human body is supplemented when the sweet potato leisure food is eaten.

Description

technical field [0001] The invention relates to a preparation method of selenium-enriched sweet potato chips, belonging to the field of health food. Background technique [0002] According to literature reports, sweet potatoes contain a variety of nutrients needed by the human body and have anti-cancer effects. However, most sweet potato products currently adopt vacuum frying and hot air drying technology, and the produced sweet potato products have poor taste and tooth feeling, and the anti-cancer effect is not obvious. Selenium can improve human immunity, promote the proliferation of lymphocytes and the synthesis of antibodies and immunoglobulins. Selenium has obvious inhibitory and protective effects on colon cancer, skin cancer, liver cancer, breast cancer and other cancers, and its intermediate metabolite methyl enol in the body has strong anticancer activity. At the same time, selenium has the effect of reducing and alleviating the toxicity of heavy metals. Selenium...
