A kind of eggshell byproduct comprehensive utilization method
The present invention proposes a kind of eggshell byproduct comprehensive utilization method, including step:1) eggshell cleaning and sterilizing, 2) crush;3) dissolve:To the hydrochloric acid that mass concentration 60% is added in the eggshell crushed, 4) separate protein:Step 3) gained supernatant in add flocculant;5) complexation reaction:In having separated the clear liquid of protein there is complexation reaction chelating generation glycine chelated calcium, or addition dry ferment generation complexation reaction generation yeast chelating calcium in addition glycine;6) extrusion is dried.Eggshell byproduct comprehensive utilization method proposed by the present invention, for the method for disposal that a large amount of eggshell discarded objects that raising chicken in the countryside or birds, beasts and eggs processing enterprise discharge have clean and effective;Contain more calcareous and protein in eggshell, by separation and chelatropic reaction, produce and hold chelating calcium easily absorbed by the body, the demand in current health product market and food additives field can be met, birds, beasts and eggs processing enterprise is obtained more preferable economic benefit.
