Method for making dried sweet potato containing iodine

Abstract

The invention discloses a method for producing iodine-containing dried sweet potato, which comprises following steps: selecting fresh iodine-containing sweet potato, storing at cool and dark condition to increase the sugar content in sweet potato, washing with water, cutting into two equal or four equal parts according to sweet potato size, boiling it in pot until there is no water in pot, cooling, and drying in drying cage. The invention is characterized by simple process, no added chemical component and artificial coloring agent, nice taste, suitability for long-distance transportation and long-term fresh keeping, and effect of preventing iodine-deficiency diseases (IDD).

Description

technical field [0001] The invention relates to a preparation method of iodine-containing dried sweet potatoes. Background technique [0002] Iodine is an essential trace element for the human body. It plays an extremely important role in the metabolic process of the human body. More than one-third of the iodine in the human body exists in the form of the thyroid gland. Without iodine, the thyroid gland cannot synthesize thyroxine. It has biological functions such as promoting protein synthesis, activating more than 100 enzymes, regulating energy conversion, accelerating growth and development, and maintaining the structure of the central nervous system. Therefore, iodine deficiency in the human body will lead to a series of physiological disorders and abnormal biological functions, such as goiter And cretinism, especially iodine deficiency in the growth and development of infants, can cause intellectual disability. The overall impact of this iodine deficiency on the human b...

However, it has also been exposed in practice for many years that there are some obvious defects in this measure: the one is that the inorganic iodine added in table salt is volatile, and part of the iodine will be lost during storage, transportation and cooking, so the concentration of iodine added in table salt is very low. In addition, there are obvious individual differences in the absorption of inorganic iodine in salt by the human body, so that it is difficult to quantitatively evaluate its biological effectiveness; second, the iodine in the organism has the characteristics of double thresholds, that is, high iodine or low iodine Iodine will have different properties and different degrees of biological effects on the body. High iodine intake can also cause disease. Studies have shown that thyroid cancer is also related to excessive intake of iodine. People of different ages and categories (such as children, adults, Pregnant women and breast-feeding mothers) have very different iodine requirements every day. When iodine supplementation is implemented for people who are really deficient in iodine, people who are not deficient in iodine and even a few people who take too much iodine should be supplemented with iodine forcibly. According to relevant data, the incidence of hyperiodine disease has increased due to excessive iodine intake in China in recent years, and it is spreading; third, in areas with severe iodine deficiency, once iodized salt is stopped, the prevalence of IDD will increase. will increase, which shows that salt iodization is a temporary rather than a long-term measure to fundamentally improve the iodine deficiency situation
