Embodiment 1

[0014] The preparation method of eucalyptus leaf natural meat quality improver is as follows: freshly collect 30kg of eucalyptus leaves Zhanjiang Guanglin No. Plate and frame filter once, then filter once through 0.22μm ceramic membrane, add 180L of 60% ethanol to the filter residue again, extract at 45°C under normal pressure for 2.5 hours, filter once with plate and frame, then filter once through 0.22μm ceramic membrane, and combine The filtrate enters the distillation pot, concentrates until the ethanol is completely removed, and recovers the ethanol. The concentrated solution is spray-dried at an air inlet temperature of 150°C, a feed rate of 70rpm, and an atomizer frequency of 25Hz, which is the natural succulent quality of eucalyptus leaf extract Improver.

Embodiment 1

[0015] Comparative Example 1 : Referring to the extraction process of the paper "Research on the Antioxidative Activity of Eucalyptus Polyphenols of Guanglin No. 9", weigh 10kg of eucalyptus leaf powder, add 20 times the volume of 70% ethanol solvent, ultrasonic extraction twice, each time for 30min, vacuum extraction Filter, combine the filtrates, and obtain the eucalyptus leaf extract after rotary evaporation of the organic solvent under reduced pressure.

Embodiment 2

[0016] Comparative example 2 10 kg of eucalyptus leaf powder was weighed, 20 times the volume of 70% ethanol solvent was added, extracted twice under normal pressure, each time for 30 minutes, vacuum filtration was performed, the combined filtrate was eucalyptus leaf extract after decompression rotary evaporation of the solvent.

[0017] As can be seen from Table 1, the preparation method of Eucalyptus leaf extract provided by the present invention is compared with the paper "Research on Antioxidant Activity of Eucalyptus Leaf Polyphenols No. Wherein the content of main components is obviously increased, which further improves the extraction efficiency of eucalyptus leaves.

Abstract

The invention provides a eucalyptus leaf extractive natural meat quality improver. Main components of the eucalyptus leaf extractive natural meat quality improver mainly comprise 10-16% of oenothera biennis essence B, 1.5-2.5% of tellimagrandin I, 0.5-1.5% of England ellagic acid, 0.2-0.4% of clorodendron eyrtophyllum tannin D and 0.1-0.35% of 1,2,3,4,6-pentagalloylglucose; the eucalyptus leaf extractive natural meat quality improver is mainly used for improving the meat quality of livestock and poultry such as chicken and pigs and a safe and efficient novel natural eucalyptus polyphenol meat quality improver is formed. The improver has the advantages of low price, simple preparation method and small investment and can be conveniently applied to a feed additive. The improver can be used for greatly relieving animal stress and has the effects of enhancing the oxidation resistance of organisms, reducing the lipid peroxidation, enabling the meat color to be bright, improving the tender degree of the meat, reducing the dripping loss and the like.

Description

technical field [0001] The invention relates to a feed meat quality improving additive for livestock and poultry and a preparation method thereof, in particular to a feed additive containing eucalyptus leaf extract which can improve the meat quality of livestock and poultry products, and belongs to the field of feed additives. Background technique [0002] 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 managemen...
