Problems solved by technology

Usually people process kelp into dishes to supplement iodine, but it needs to be washed and soaked for 2-3 hours before processing, which is not convenient. At the same time, because the digestive juice in the human body lacks enzymes to digest kelp, the digestion and absorption rate of edible kelp is extremely high. Low, the iodine in the existing iodized salt is mainly potassium iodate and potassium iodide, which can play a certain role in iodine supplementation, but the nature of potassium iodide is unstable, and it is easy to volatilize and lose when it sees light and heat during processing and transportation, especially The loss in the cooking process is serious, resulting in insufficient human intake. Potassium iodate is more stable than potassium iodide, but its absorption, conversion and utilization rate in the human body is low, and it has toxic and side effects
[0003] Chinese Patent Announcement No. CN101643430A, announced on February 10, 2010, discloses a method for extracting kelp organic iodine from kelp root, which is characterized in that it includes the following processing steps: cleaning and soaking of raw materials, extracting extract, adding ethanol to extract clear liquid, recover alcohol, adjust the pH value, separate the supernatant liquid, and the turbid liquid at the bottom is the product of the present invention through vacuum freeze-drying. The product has high purity and good rehydration property. The disadvantage is that a large amount of Edible ethanol has high cost, complex extraction steps, low product yield and high energy consumption in the production process

Abstract

The present invention relates to a kelp extract iodine tablet and a preparation method thereof, and belongs to the technical field of food science. A purpose of the present invention is to provide a kelp extract iodine tablet with characteristics of stable product quality, convenient eating and high absorption utilization rate, and a kelp extract iodine tablet preparation method. The kelp extract iodine tablet is prepared from the following components, by weight, 50-60 parts of a kelp extract, 5-8 parts of sucrose, 10-25 parts of starch, 10-15 parts of 16% starch paste, 3-5 parts of magnesium stearate, 3-5 parts of talc powder, and 0.2-0.5 part of vitamin. The kelp extract is rich in organic iodine, polypeptides, amino acids, unsaturated fatty acids, vitamins, trace elements and other ingredients, wherein people with daily iodine deficiency can adopt the kelp extract to supplement iodine, and an absorption utilization rate is high. The kelp extract iodine tablet has characteristics of low production cost, convenient eating and good taste, and is a good inorganic iodine tablet substitute.

Description

technical field [0001] The invention relates to an iodine tablet extracted from kelp and a preparation method thereof, belonging to the technical field of food science. Background technique [0002] Kelp is a kind of seaweed with high iodine content, generally containing 3-5‰ iodine, up to 7-10‰. Iodine and alginic acid extracted from it are widely used in medicine, food and chemical industry. Iodine is one of the essential elements for the human body. Iodine deficiency will cause goiter. Eating more seaweed can prevent this disease, prevent arteriosclerosis, and reduce the accumulation of cholesterol and fat. Usually people process kelp into dishes to supplement iodine, but it needs to be washed and soaked for 2-3 hours before processing, which is not convenient. At the same time, because the digestive juice in the human body lacks enzymes to digest kelp, the digestion and absorption rate of edible kelp is extremely high. Low, the iodine in the existing iodized salt is ma...
