Embodiment 1

[0015] Freshly collect 30Kg of leaves of Eucalyptus No. 9 in Zhanjiang Guanglin, avoid light and dry in the shade, crush to 60 mesh, add 240L of 70% ethanol, centrifugally filter, add 180L of 70% ethanol again, and centrifugally filter again, combine the filtrate, enter the still, concentrate Until there is no alcohol smell, and ethanol is recovered, the concentrated solution is spray-dried at an air inlet temperature of 150°C, a feed speed of 70rpm, and an atomizer frequency of 25Hz, and the eucalyptus leaf extract natural meat quality improver is obtained after the solvent is removed.

[0016] The application test of eucalyptus leaf extract natural meat quality improver in broiler chickens showed that adding 0.01 to 0.1% eucalyptus leaf extract natural meat quality improver in the diet significantly improved the quality of broiler chicken, and the pH of chicken breast 45min It increased by 4.93% (P<0.01), the drip loss rate decreased by 11.06% (P<0.01), the shear force decrea...

Embodiment 2

[0018] Freshly collect Guangxi Guanglin No. 9 eucalyptus leaves 40Kg, avoid light and dry in the shade, crush to 40 mesh, add 320L of 90% ethanol, centrifugally filter, add 240L of 90% ethanol again, and centrifugally filter again, combine the filtrates, enter the still, concentrate Until there is no alcohol smell, and ethanol is recovered, the concentrated solution is spray-dried with an air inlet temperature of 170°C, a feed speed of 90rpm, and an atomizer frequency of 28Hz. After removing the solvent, it becomes a natural meat quality improver of eucalyptus leaf extract. The amount added in the feed is 0.01-0.1%.

Embodiment 3

[0020] Freshly collect 50Kg of Zhanjiang DH32-29 eucalyptus leaves, dry them in the dark, crush them to 50 meshes, add 400L of 70% ethanol, centrifugally filter, add 300L of 70% ethanol again, and centrifugally filter again, combine the filtrates, enter the still, concentrate to There is no alcohol smell, and ethanol is recovered. The concentrated solution is spray-dried at an air inlet temperature of 190°C, a feed speed of 90rpm, and an atomizer frequency of 28Hz. After removing the solvent, it becomes a natural meat quality improver of eucalyptus leaf extract. The amount added in the feed is 0.01-0.1%.

Abstract

The invention provides a eucalyptus leaf extract natural meat quality improver, and a preparation method and a purpose thereof. According to the invention, eucalyptus leaves are dried in a shade at a place protected from light; the eucalyptus leaves are crushed to 40-60 meshes; the eucalyptus leaf is added into an extraction tank; 40-95% ethanol is added, and the eucalyptus leaf is extracted twice; filtrates are combined, and the combined filtrate is added into a concentration device; the material is concentrated until only water is left; and spray-drying is carried out, such that the meat quality improver is obtained. The meat quality improver provided by the invention has a total phenol content of 25-40%. The meat quality improver comprises 6-12% of evening primrose element B, 1-2% of tellimagrandin I, and 0.1-0.15% of 1, 2, 3, 4, 6 penta-alloyl glucose. The natural meat quality improver provided by the invention is used as a livestock and poultry feed additive, and has the effects such as body antioxidant capacity enhancing, lipid peroxidation reducing, meat color brightening, meat tenderness improving, drip loss reducing, and meat shelf live prolonging.

Description

[0001] technical field [0002] The invention relates to a feed additive for livestock and poultry, in particular to a feed additive extracted from eucalyptus leaves that can improve the meat quality of livestock and poultry products, and belongs to the field of feed additives. Background technique [0003] Animal husbandry has always been an important pillar industry of my country's agriculture. Since the reform and opening up, with the guidance of the market economy and the popularization of breeding science and technology, my country's animal husbandry production has developed rapidly and achieved remarkable results. With the abundance of livestock and poultry products and the improvement of human living standards, people increasingly demand that meat products are not only safe and nutritious, but also have better taste and sensory properties. However, the stress brought about by genetic selection and production management to improve production performance has reduced th...
