A method for preparation of iodizing agent for the use in the formulation of iodized salt that offers excellent stability of iodine in iodized salt is developed and the unrefined salt iodized with this compound was tested for its stability in presence of moisture, temperature and metal salts at higher temperature. The hydrotalcite type layered compound was used to prepare such compound and part of carbonate was substituted with iodate anion. The iodizing agent exhibited excellent stability of iodine in iodized salt.

The present invention relates to one new kind of compound, named chemically as 8-octyl berberine salt (hydrochloride, bromide, iodide or hydrofluoride). The compound has the molecular expression of C28H34O4N .X, where, X is F-, Cl-, Br-, I- or other anion, and the structural formula as shown. Compound 8-octyl berberine salt has antibacterial activity, antilipemic activity and hypoglycemic activity obviously higher than that of berberine salt, and possesses excellent antibacterial, antilipemic and hypoglycemic medicinal value.

The invention discloses a novel iodizing agent containing latent elemental iodine and preparation of iodized salt therefrom. The iodizing agent comprises a mixture of iodide and iodate in solution form in 5:1 molar ratio. The said iodizing agent may be prepared cost-effectively through the reaction of pure iodine crystals with a suitable alkali. Iodized salt prepared therefrom is stable in the pH range of 7.0-8.0 whereas it releases the latent elemental iodine under acidic conditions such as that which prevails in the stomach.

The invention discloses an extraction method of algae iodate, and belongs to the fields of algae processing and food or feed additives. The method comprises the following steps: with brown alga as a raw material and water as an extracting liquid, carrying out multistage countercurrent extraction, carrying out vacuum concentration on the extracting liquid at 55-65 DEG C into a clear liquid, and stopping heating and concentrating when the specific gravity is 1.30-1.40; carrying out primary centrifugal separation when the clear liquid is hot to remove a high-temperature salt; cooling and removing a concentrated liquid of the high-temperature salt; carrying out secondary centrifugal separation, and removing excessive crude mannitol to obtain the concentrated liquid; and adding chitosan to remove heavy metal and arsenic in the concentrated liquid, and centrifuging, so as to obtain an algae iodate extracting liquid. The algae iodate extracted by the method is low in heavy metal content, and high in extraction rate; and meanwhile, a composite algae iodate salt additive prepared from the components such as algae iodate composite potassium iodide, potassium chloride and glutamic acid extracted by the method is good in heat stability.

The present invention relates to a process for the preparation of stable iodate-exchanged hydrotalcite with zero effluent discharge. The iodate-exchanged hydrotalcite produced is useful as iodizing agent. The invention further relates to utilization of alkaline effluent generated in the process of ion exchange of iodate into SHT so as to fully recycle the residual iodate anion and also utilize the alkali generated in the process for production of additional quantities of iodate through reaction with iodine crystals followed by electrochemical oxidation to obtain pure aqueous solution of iodate salt which can be reused for preparation of the stable iodizing agent. The process gives zero effluent discharge hence economical.
