Embodiment 1

[0051] A preparation method of a yew fermented liquid product with antibacterial function, comprising the following steps:

[0052] (1) prepare yew slurry

[0053]Take fresh yew leaves, wash them with clean water for three times, then use sterile water to perform ultrasonic cleaning for 5 minutes, then drain the water to make the water content 45%, and irradiate them for 3 minutes under the ultraviolet wavelength of 254mm to sterilize. Freeze-drying technology, freeze-dried at -20°C, and finally mixed the leaves of yew with sterile water at a ratio of 1:2 by weight, and then crushed them in a wall breaking machine at a speed of 45,000 rpm to obtain yew slurry;

[0054] (2) Enzymatic hydrolysis of yew pulp

[0055] Add a compound enzyme composed of cellulase and bromelain to the yew pulp, mix it evenly, let it stand for 24 hours, and carry out enzymatic hydrolysis treatment to obtain the enzymatic yew pulp; wherein, the quality of the compound enzyme is yew 0.2% of the slurr...

Embodiment 2

[0065] A preparation method of a yew fermented liquid product with antibacterial function, comprising the following steps:

[0066] (1) Prepare yew pulp

[0067] Take fresh yew leaves, wash them with clean water three times, then use sterile water to perform ultrasonic cleaning for 3 minutes, then drain the water to make the water content 55%, and then irradiate them for 8 minutes under ultraviolet wavelength 254mm to sterilize. The sterilized yew leaves are used Rapid freeze-drying technology, freeze-dried at -22°C, and finally mixed yew leaves and sterile water at a weight ratio of 1:1.8, and then crushed in a wall breaking machine at a speed of 40,000 rpm to obtain red beans fir pulp;

[0068] (2) Enzymatic hydrolysis of yew pulp

[0069] Add a compound enzyme composed of cellulase, hemicellulase and bromelain to the yew pulp, mix it evenly, let it stand for 20 hours, and perform enzymatic treatment to obtain the enzymatic yew pulp; wherein, the compound The quality of t...

Embodiment 3

[0079] A preparation method of a yew fermented liquid product with antibacterial function, comprising the following steps:

[0080] (1) Prepare yew pulp

[0081] Take fresh yew leaves, wash them with clean water three times, then use sterile water to perform ultrasonic cleaning for 3 minutes, then drain the water to make the water content 50%, and then irradiate them for 10 minutes under ultraviolet wavelength 254mm to sterilize. The sterilized yew leaves are used Rapid freeze-drying technology, freeze-dried at -25°C, and finally mixed yew leaves and sterile water at a weight ratio of 1:1.8, and then crushed in a wall breaking machine at a speed of 80,000 rpm to obtain red beans fir pulp;

[0082] (2) Enzymatic hydrolysis of yew pulp

[0083] Add a compound enzyme composed of cellulase, hemicellulase and papain to the yew pulp, mix it evenly, let it stand for 24 hours, and perform enzymatic hydrolysis treatment to obtain the enzymatic yew pulp; wherein, The mass of the comp...

Abstract

The invention discloses a preparation method of a taxus chinensis fermentation liquor product with a bacteriostatic function, and the method comprises the following steps of: pulping taxus chinensis leaves to prepare taxus chinensis pulp, adding compound enzyme for enzymolysis, adding a carbon source, organic acid, inorganic salt and bacillus coagulans, and performing primary fermentation to obtain primary fermented taxus chinensis pulp; adding an organic acid, a nitrogen source, a carbon source and a composite strain, and carrying out secondary fermentation to prepare secondary fermented taxus chinensis pulp; adding a carbon source and a composite strain into the fruit juice, and performing fermenting to obtain fermented fruit juice; and filtering the secondary fermented taxus chinensis pulp, mixing the filtered liquid with the fermented fruit juice to obtain a mixed liquid, conducting chelating and sterilizing, and taking a supernatant to obtain the product. The taxus chinensis fermentation liquor product with the bacteriostatic function prepared by the method is slightly bitter in taste, high in effective component content, simple in preparation method, easy to operate and short in fermentation time.

Description

technical field [0001] The invention relates to the technical field of fermented products, in particular to a yew fermented liquid product with antibacterial function and a preparation method thereof. Background technique [0002] Taxus is an evergreen tree or shrub. It is generally called "yew" among the people. It contains a variety of medicinal ingredients. Taxus contains paclitaxel and other compounds. It is developed and utilized as an anti-tumor injection. It also contains flavonoids and other compounds. , has immune and anti-tumor, anti-virus and antioxidant activities. The medicinal function of yew is recorded in "Compendium of Materia Medica", which can be used to treat cholera, typhoid and other diseases. Its medicinal function is also mentioned in "Materia Medica". Relevant records: "Yew can be used as medicine, diuresis, menstrual flow, and kidney disease, and the skin is easy to vomit, but the wood and leaves do not vomit." The use of yew plants in folk and trad...
