With application of sodium alginate additive, wheat gluten rate can be enhanced, viscidity of noodles can be improved, tensile camber can be promoted, breaking rate and recycled rate of wet noodle are lessened. While eating, the noodles have good resistance to boil and pickle with good taste, high softness and no peculiar smell. b. Additive of bread and cake wheat gluten rate of flour can be enhanced, stretching ability, toughness and elasticity of dough can be improved, then the dough can contain a great deal of air, therefore the bread will be soft, elastic and not leave dregs. At the same time, emulsification of eggs can be improved after adding sodium alginate with good foaming ability, then expanding sponge will be formed with dense and even hole, high elasticity and good resistance to dry. c. Tasty and refreshing cold jelly and jelly gel, composed of sodium alginate after adding different juices and cane sugars, as well as calcium ion, will not melt while being heated, therefore it can be boiled and sterilized. Making use of characteristics of the gel, transparent, soft and tasty cold jelly can be made. besides the application mentioned above, sodium alginate can also be used in ice cream as stabilizer and thickening agent, in bionic food and gel cake stuffing to form gel. pharmacy indystry a. Moulage materials for dentistry in the past, moulage for dentistry is made of rubber and gesso which is substituted by sodium alginate moulage materials with simple operation and accurate tooth form. In addition, moulage materials and coagulator are packed into two bags, while using, mix the two then they will be hard set within several minutes. b. Haemostatic fiber type sedimentation of sodium alginate liquid appears in acid or calcium salt and the molecular structure is in the form of thread, therefore it can be made of different haemostatics, such as hemostatic gauze, hemostatic sponge, scalding gauze and spraying haemostatic. c. Resist and hinder radioelement and harmful metal as sodium alginate has special ability to transmit some elements, thus it has good effect to prevent sr.absorption, as well as good treatment. Being contaminated by radiostrontium, take some sodium alginate orally, radiostrontium in the alimentary canal can be discharged quickly. d. Ointment, tablet and preparation making use of the thickening and gel characteristics, sodium alginate can be used as additive of different medicines, for instance sulfur ointment, which can cure skin disease, is mixed by sponge natrium and lanolin; sodium alginate can also be mixed with sulfonamide and used as oculentum, and used as conception control ointment after mixing with benzene and acetic acid. Glucosidase algin can be made into capsule for intestine so that the medicine can stop in the intestine to enhance medical treatment. printing& textile industry a.printing pulp sodium alginate has been used for sizing twist yarn, neatening pulp and printing pulp for a long time, especially the printing pulp. Sodium alginate has special performance as active dyestuff color paste. After reaction between fiber and active dyestuff, the dyestuff will be fixed on the fiber, printing pulp should not disturb or take part in the reaction in the process of dying. If color paste takes part in the reaction, it will be fixed on the fiber resulting hard fiber, crisp performance and bad color. While using sodium alginate as printing pulp, dyeing process between active dyestuff and fiber will not be affected, while the grain is clear and bright with good feelings. It fits for dyeing cotton, as well as stamping wool, silk and composite fiber. sodium alginate with medium viscidity and low viscidity fits for requirement from screen type printing to roller type printing paste. Actually, printing paste is stable with application of low viscidity sodium alginate, then top grade printing paste can be gained. Dense membrane can be got in the drying process adding painting rate. b. synthetic fiber after mixing with short fiber of asbestos and concretion treatment with lime acetate liquid, the asbestos can be prevented to fly away without affecting health of human being. other industries: water-soluble sodium alginate can substitute dispersant of some rosin paper pulp or paper sizing for paper making, then smoothness of paper surface can be enhanced. At the same time, it can regulate absorption of printing ink, wax and oil to enhance its resistance to massage. Cladding of welded bar: after mixing arc welding electrodes with sodium alginate, alginato de potassio and calcium alginate, cladding of medical materials can be conglutinated, therefore enough plasticity can be gained in the extruding process. At the same time, it can be easily burned, thus splash can be lessened. in addition, sodium alginate fits for resin dope, rubber creaming agent, pole insulation layer of battery and water treatment. Moreover, it can also be used to process seeds, and applied as pesticide and antivirus materials.
