In this thesis the microcapsules low-fat playing charge-cream powder formulation was prepared and process, as well as raw material casein, fats, emulsifiers nature of its basic playing charge, including: to fight the charge and expansion rate, slurry separation fat coagulation, the plastic foam stability maintenance, penetration, desorption protein and sensory quality. Also analyzed the basic mechanism of the role of these materials. The following results were obtained: 1. Preparing microcapsules low fat Battle charge cream powder, and its quality inspection. The regular round of this cream powder particle shape, color pure white, milk flavor, delicate and dry, good fluidity; embedding efficiency is relatively high, up to 93.7%, good stability; relatively smooth surface, no cracks. Room temperature to fight the charge, the most suitable to fight the charge and speed of 245rpm (8 files) best suited to fight the charge time is 6min plastic foam expansion ratio up to 4.20; fight charge at the end of slurry separation; standing storage, plastic foam stability maintenance time up to 280min; the ideal playing charge time, the viscosity of the plastic foam gradually increased, the maximum amounted to RMB73, 745 Pa · s; good low-fat to fight the charge and cream powder plastic foam molding, foam flu foot, full brightness . In addition, it grease content, eliminating the sense of heavy oil, more use of advantages. Casein raw materials of low-fat cream powder quality playing charge. Casein modeling viscoelastic foam fat bracket can be increased to improve the stability of the bubble. Sodium caseinate optimum addition amount of 6%, the emulsion fat adsorption layer structure on the protein desorption amount of 48.65 mg / g, the expansion coefficient reached 4.20, the penetration of 49%, sticky foam modeling moderate elasticity, does not stand to discover. This cream powder when modeling foam has reached a state suitable for most applications. When the added amount of sodium caseinate is less than or higher than 6%, are not conducive to high-quality a modeling foam formation. Oil raw materials and low-fat cream powder to fight the charge directly related to the performance. Prepared to fight the charge and cream powder grease selection of hardened palm oil as raw material. The amount of grease will determine fat coagulation ability, which in turn playing with cream powder charge and nature are closely related. The optimum addition amount of hardened palm oil 25%. Charge when playing lipid droplets of condensate and the rate is relatively fast, coagulation is relatively high at 66.75%, the fully plastic foam into the air, the higher expansion rate; slurry separation to 0, pull up the tip of a long vertical bending collapse , better hardness of the plastic foam, suitable viscosity and toughness; lay the plastic foam appearance smooth brightness, there is no sense of rough, forming good, hollow stacked close adhesion, foam is enough sense of quality. 4 multiplexed with the management of the mixed emulsifier can procure fat replacement coagulation effect occurs, while its augmentation can also affect the nature of the playing charge of the low-fat cream powder. 0291 can be used to increase the viscosity and toughness of low-fat cream powder Battle modeling foam, select is added to the amount of 0.7% when it is multiplexed with other emulsifiers with effect best; 0294 pairs to improve the low-fat cream powder playing the expansion rate of the charge and plastic foam play a vital role, select Add 2.0%, to fight charge at the end of the expansion rate of the plastic foam can reach 4.20; 0288, the main role is the common complex with the right amount of 0294 expansion, it is the most effective way to add 1.2%; 02,096 pairs of low-fat cream powder to fight plastic foam stability is essential, high-quality cream powder have both high expansion rate should also have a longer maintenance of stability time. 02096 addition is 0.8%, with other emulsifiers effect, stability maintenance time to 280min. At the same time, playing charge plastic foam sensory quality is good, the nature of the charge of the fight reached the ideal state applicable.
