Problems solved by technology

According to the content disclosed in the patent, the composition can effectively reduce the fat content in milk and increase the content of CLA, but there is no specific report on the effect of the composition on the milk production of cows
This patent also discloses the preparation method of the above-mentioned composition containing conjugated calcium linoleate. However, this method is used to produce in the same equipment, and various components in the raw vegetable oil are brought into the product, and the obtained product is conjugated The percentage composition of calcium linoleate is lower than 80% (disclosed content of embodiment); And saturated fatty acid in the product, as the content of palmitic acid and stearic acid etc. is higher, conjugated calcium linoleate accounts for total fatty acid calcium The mass percentage is lower than 85%; secondly, the obtained product is a block solid, although it can meet the requirements as a feed additive after crushing, its properties, color, etc. are not very satisfactory

Abstract

The present invention discloses one kind of composition containing calcium conjugate linoleate for increasing the milk output of milk cow and its preparation process. The composition is prepared with vegetable oil as material, and through ester exchange reaction, molecular distillation, saponification, isomerization and metathetical reaction. It consists of alphatic calcium, water and impurity salt; and the alphatic calcium includes calcium conjugate linoleate accounting for 82-90 wt% of the composition, calcium palmitate, calcium stearate, calcium oleate and calcium linoleate accounting for 8-15 wt% of the composition. It has high calcium conjugate linoleate content, controllable content of other kinds of alphatic calcium and excellent physical character. It is used in raising milk cow to raise milk output obviously.

Description

technical field [0001] The invention relates to a composition containing calcium conjugated linoleate and a preparation method thereof, in particular to a high-purity calcium conjugated linoleate product for increasing milk production of dairy cows and a preparation method thereof. Background technique [0002] Conjugated Linoleic Acid (CLA) belongs to polyunsaturated fatty acid and is a group of isomers of linoleic acid. Adding conjugated linoleic acid in the feed can significantly increase the CLA content in milk and reduce the saturated fatty acid in milk. In order to avoid the destruction of conjugated linoleic acid when it passes through the rumen of cows, the calcium salt of conjugated linoleic acid is often used as a feed additive. Studies have shown that the addition of calcium conjugated linoleate (CLA-Ca) can increase the content of CLA in milk and reduce the content of saturated fatty acids in milk. However, there are few studies on the effect of CLA-Ca on milk ...
