Embodiment Construction
[0044] The liposome of present embodiment has the function of reducing fat and replenishing calcium is to carry out as follows:
[0045] 1. Add acetone to the concentrated soybean phospholipid or egg yolk to deoil, heat to 45°C and stir well, then centrifuge with a centrifuge, take the insoluble precipitate, add absolute ethanol to dissolve and extract, purify at 55°C for 90 minutes, and then remove For ethanol insoluble matter, add aluminum oxide to the ethanol soluble matter for adsorption and decolorization, then filter, distill the filtrate under reduced pressure, distill off ethanol, and dry it in vacuum to obtain purified lecithin. Water and ethanol are used to obtain oily phase substances.
[0046] 2. Soak eggshells or raw materials rich in calcium carbonate in vinegar with a concentration of not less than 9g / 100ml, the mass ratio of raw materials to vinegar is 1:20; or according to the mass of calcium hydroxide, anhydrous acetic acid and water The ratio is 1: 2: 16, f...
