The technical principle of the invention is as follows:
the method comprises the steps of adding a colloid adsorbent into the crude butter to remove colloid substances in the crude butter, and filtering to obtain the non-foaming finished butter. The colloidal adsorbent in the present invention includes silica, diatomaceous earth and perlite.
The silicon dioxide has Lewis acid-alkali characteristics, can be combined with phospholipid with phosphate groups, has the characteristics of regular shape, controllable particle size range, large specific surface area, strong adsorption capacity and the like, is covered with phospholipid molecules on the surface in a molten state, forms a silicon dioxide-phospholipid compound due to the strong adsorption of the silicon dioxide, improves the stability of phospholipid molecules and avoids the phospholipid molecules from dissociating in grease. Therefore, the silicon dioxide is used as a carrier to cure the phospholipid of the beef tallow, and the aim of separating the phospholipid from other substances of the beef tallow is fulfilled.
In addition, the colloidal adsorbent contains diatomaceous earth and perlite as filter aids for filtering out the silica-phospholipid complex. The proportion of the diatomite and the perlite is used for aiming at the characteristics and the particle size distribution state of the silicon dioxide-phospholipid compound, and the diatomite and the perlite are combined according to the proportion, so that the diatomite has the adsorption and bridging characteristics, a stable precoating layer is formed, the peeling is not easy to occur, and the filtering effect is ensured. Specifically, the perlite has light specific gravity and irregular strips, so that a good bridging effect can be achieved, high porosity is maintained, and the adsorption effect of the diatomite is utilized, so that filter aid particles are better bridged and arched, a good bridging phenomenon among the particles is formed, a rigid bone structure is formed, and the filtering quality is improved.
The phospholipid in the grease is usually light yellow to brown due to the difference of degumming process and storage conditions, the chroma of the beef tallow after adsorption and filtration is reduced, one part of chroma is reduced because the phospholipid is removed, and the silicon dioxide can also be used as a decoloring agent for decoloring the grease, and simultaneously, the pigment in the beef tallow is also adsorbed, so that the chroma of the grease is further reduced.
The degumming process in the invention has simple and efficient process and low equipment requirement, although the degumming process in the prior art can effectively remove colloid, the requirement for subsequent removal of additives is high due to improper selection of colloid adsorbent, if the additives need to be removed under high temperature and high vacuum, the flavor is rapidly volatilized, the loss is large, the application range is limited, the requirement on equipment is high, and the cost is increased. The degumming process of the invention is based on the removal of crude oil colloid, and the subsequent removal of degumming adsorbent only needs filtration without complex process and equipment requirements, and the non-foaming beef tallow can be obtained by conventional filtration equipment. Wherein, the filtering equipment adopts a leaf filter or a plate and frame filter, the operating parameters of the filtering equipment are suitable for filtering the silicon dioxide-phospholipid compound, and the filter aid can exert the maximum filtering effect.
