Benefits of technology

This patented technology involves making Cadrake deoxidation without adding harmful chemicals like selenium or sulfur dioxide during processing. By utilizing this technique, cadrasia becomes less dangerous because they contain fewer impurities. They also have specific ingredients added at different stages throughout their manufacturing processes to improve its properties. These technical results help prevent contamination issues while producing valuable commercial products.

Problems solved by technology

This patented describes different methods for producing okadai from sea plants called shrimps like cladoskids and cuttlefish. These crocks contain selenium, zinc, calcium, iron, copper, manganese, polysilicon dioxyhemoglobin, chlorophyll, taurenosulfurane, selenite, gallium, ammonia, sulfurous acid, citrate, carboxylates, glucose monomethoxytritinosynthesis metabolites, urolithochondria, fission yeast cells, pyrenaferrite, lycopene, beta cyclodextrin, betaine, guarme flakes, nanosized particles containing silver, gold, platinum, indanthroverdanets, and chemotherapy agents including alkali metal salts. However, these existing processes require expensive materials and produce harmful byproducts during manufacturing process steps. Therefore, there remains room for improvement within this field.

Abstract

The invention discloses a method for extracting sodium alginate and other organic matters from Hizikia fusifarme through arsenic removal. The method comprises the steps of (1) arsenic removal treatment, (2) enzymatic hydrolysis treatment, (3) iodine extraction, (4) mannitol extraction, (5) dilute alkali digestion, (6) decoloring, (7) calcium coagulation-ion exchange and (8) sodium alginate preparation. A Hizikia fusifarme arsenic removal technology greatly reduces the content of arsenic in Hizikia fusifarme. A compound enzyme prepared through using protease, pectase and cellulase according to a scientific ratio is used to realize raw material pretreatment, so the product extraction rate is improved in order to realize recycle of production water; the concentrations of iodine and mannitol in a pretreatment liquid are high, and the above extraction method has the characteristics of simplicity, production cost reduction and energy consumption reduction; and compared with present industrial production methods, the method disclosed in the invention has the advantages of saving of above 90% water, great reduction of the water resource consumption and the sewage emission, and environmental pollution reduction.
