Embodiment 1

[0025] The preparation process of the Ilex Kudingcha extract specifically includes the following steps:

[0026] (1) Choose fresh and old leaves or young leaves of Ilex Kudingcha without mold and pests as raw materials, and remove impurities;

[0027] (2) Dry the raw materials under the condition of 100±5℃, until the water content of the raw materials is 8-10wt%, so as to inactivate the biological enzymes in the raw materials and prevent fermentation, and then crush the raw materials to a particle size The particles of 6-10mm were extracted and treated with 70v% ethanol for 6h;

[0028] (3) Centrifuge the extract at a speed of 8000 rpm for 15 minutes to remove impurities in the extract, and then concentrate the extract in a vacuum environment above 0.09 Mpa at 30 to 50°C to a density of 1.05 g / cm 3 about;

[0029] (4) Freeze and purify the concentrated extract at -5~0℃ for 3h, then sterilize it with 100℃ steam for 2.5h. After sterilization, the solid content in the extract is 40% abo...

[0032] The preparation process of the Ilex Kudingcha extract specifically includes the following steps:

[0033] (1) Choose fresh and old leaves or young leaves of Ilex Kudingcha without mold and pests as raw materials, and remove impurities;

[0034] (2) Dry the raw materials at 110±5℃ until the water content of the raw materials is 12-15wt%, then crush the raw materials into particles with a particle size of 10-15mm, and extract them with 75v% ethanol 2.5h;

[0035] (3) Centrifuge the extract at 5000 rpm for 30 minutes to remove impurities in the extract, and then concentrate the extract in a vacuum environment below 0.09 Mpa at about 50°C to a density of 1.15 g / cm 3 about;

[0036] (4) Freeze and purify the concentrated extract at -10~-5℃ for 1h, and then sterilize it with steam at 105±5℃ for 1h. After sterilization, the solid content in the extract is within About 45%;

[0037] (5) The extract is spray-dried to obtain a finished product. After testing, the finished product has a t...

[0039] The preparation process of the Ilex Kudingcha extract specifically includes the following steps:

[0040] (1) Choose fresh and old leaves or young leaves of Ilex Kudingcha without mold and pests as raw materials, and remove impurities;

[0041] (2) Dry the raw materials at 100±5°C until the water content of the raw materials is 10-12wt%, then crush the raw materials into particles with a particle size of 4-8mm, and extract them with 80v% ethanol. 1h;

[0042] (3) Centrifuge the extract at 20000 rpm for 5 min to remove impurities in the extract, and then concentrate the extract in a vacuum environment at about 45°C to a density of 1.2 g / cm 3 about;

[0043] (4) Freeze and purify the concentrated extract at about -5°C for 1 hour, and then sterilize it with steam at 105±5°C for 1 hour. After sterilization, the solid content in the extract is 50% about;

[0044] (5) The extract is spray-dried to obtain a finished product. After testing, the finished product has a total flavonoid co...

Abstract

The invention relates to a preparation process of a Ilex latifolia Thunb extractive, comprising the following steps of: carrying out enzyme killing and drying treatment on Ilex latifolia Thunb used as a raw material at the temperature of 10-115 DEG C until the water content of the raw material is not more than 15wt%; then crushing the Ilex latifolia Thunb and extracting with 60-80v% ethanol; then removing impurities out of extraction liquid by a centrifugal separation mode; then carrying out vacuum concentration on the extraction liquid until the density is not more than 1.10g / cm3; then carrying out freezing purification and sterilization treatment in sequence; and finally carrying out spray drying on the extraction liquid to prepare a finished product. In the invention, various active ingredients in the Ilex latifolia Thunb are extracted with high efficiency by combining the technical measures of enzyme killing and drying, crushing, extracting, vacuum concentration, spray drying and the like in a way which is never thought by industry insiders, and moreover, the invention has brief process flow and simple operation and does not need complex instrument and equipment and does not need to consume a large number of organic solvents, and therefore, the preparation process has low cost, safety and environmental protection.

Description

Technical field [0001] The invention relates to a process for preparing an extract of Kuding tea, in particular to a process for extracting an extract containing flavonoids, saponins, tea polyphenols and the like from Ilex Kuding tea. Background technique [0002] Kuding tea is sweet and bitter in nature, has the effects of clearing heat and cooling blood, nourishing the liver and kidneys. It is a common Chinese medicine in southern my country, and it is also a cooling, detoxifying and fitness drink popular among the people. At present, Kudingcha is usually derived from 3 species of Ilexaceae plants, 5 species of Ligustrum genus Plants of the Ligustrum family, and 1 species of Verbenaceae Fructus vulgaris. Among them, Hollyaceae plants are generally regarded as the authentic source of Kudingcha. [0003] With the improvement of living conditions, changes in diet and lifestyle, the incidence of obesity, hyperlipidemia, hypertension, fatty liver and other diseases in the population i...
