Embodiment 1

[0032] Add 1 times the weight of ethanol to lutein extract, add 20% potassium hydroxide of 0.5 times the weight of the extract, saponify at 75°C for 2 hours, add pure water 3 times the weight of the extract, filter, add 0.3 times the weight of the extract to the filtrate Hydrochloric acid, standing for stratification, vacuum concentration and dehydration of the upper layer to obtain a carotenoid composition with a total carotenoid content of 6%, wherein trans-lutein accounts for 25%, trans-zeaxanthin accounts for 10%, and monohydroxy pigment accounts for 55% , other carotenoids accounted for 10%.

[0033] The above product is mixed with 2 times of carrier to obtain a powder product with 20 g / kg of total carotenoids, and the ratio of different carotenoids remains unchanged.

Embodiment 2

[0035] Take the lutein extract with a total carotenoid content of 16%, wherein trans-lutein accounts for 74%, trans-zeaxanthin accounts for 6%, and other carotenoids account for 20%. Take the orange peel extract with a total carotenoid content of 4%, wherein monohydroxy pigment accounts for 80%, and other carotenoids account for 20%. Mix 20kg of lutein extract and 80kg of orange peel extract to obtain 100kg of a product with a total carotenoid content of 6.4%. Among the total carotenoids, trans-lutein accounts for 37%, trans-zeaxanthin accounts for 3%, and monohydroxy Pigments account for 40%, and other carotenoids account for 20%.

Embodiment 3

[0037] Take 32kg of natural lutein with a total carotenoid content of 5%, wherein trans-lutein accounts for 32%, trans-zeaxanthin accounts for 63%, and other carotenoids account for 5%. Get 84kg of synthetic pigments with a total carotenoid content of 10%, wherein monohydroxy pigments account for 95%, and other carotenoids account for 5%. The two are mixed to obtain 116kg of products with a total carotenoid content of 8.6%. In the total carotenoids, trans-lutein accounts for 5%, trans-zeaxanthin accounts for 10%, monohydroxy pigment accounts for 80%, and other carotenoids account for 5%. %.

Abstract

The invention relates to a carotenoid composition and application thereof. The carotenoid composition comprises the following components: 5%-40% of trans-lutein, 3%-15% of trans-zeaxanthin, 40%-80% of monohydroxy pigment and 5%-20% of other carotenoids. The composition disclosed by the invention can be applied to feeds for laying poultry, meat poultry and the like as a feed additive, and different carotenoids have a synergistic effect, so that the coloring effect of yolk, beaks, tarsometatarsal skin, sub-wing skin and the like of poultry can be improved.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a carotenoid composition containing lutein, zeaxanthin and monohydroxy pigment and its application. Background technique [0002] In order to improve the coloring effect of egg yolk of laying poultry, meat poultry beak, tarsal soles, skin under wings, etc., natural or synthetic lutein (derived from marigold), capsanthin, cantharidin, etc. are generally added to poultry feed at present. carotenoids. Among them, the natural lutein derived from marigold is used in the largest amount, and its main coloring substances include lutein and zeaxanthin. In natural lutein, the proportion of trans-lutein to the total carotenoids is generally about 80%, and the proportion of zeaxanthin is generally about 6%. There are also high-zeaxanthin products with a zeaxanthin ratio of 35%-75% obtained by converting lutein into zeaxanthin under high-temperature alkaline conditions in the market. Because ...
