Problems solved by technology

[0003] At present, drinking of lactic acid bacteria is widely prevalent in countries all over the world, but its stability is not good. Artificial culture medium with main nutritional components) together with milk powder, lactose, starch and other auxiliary materials and excipients are processed into various forms of active lactic acid bacteria products, also known as "probiotic" products

Embodiment 1

[0038] Weigh 400g of eucommia leaves, add water 3200ml (1:8) for the first time, control the decoction extraction temperature to 98°C, decoct and extract for 1 hour, collect the extract, add water 2400ml (1:6) to the leaf residue for the second time, decoct The extraction temperature is 98°C, the decoction extraction time is 45 minutes, the extract is collected, the leaf residue is added with 2400ml of water for the third time, the decoction extraction temperature is 98°C, the decoction extraction time is 30 minutes, the decoction extract is combined three times, filtered, and removed Impurities insoluble in water, then concentrated to a density of 1.20-1.25g / cm 3 , with a volume of about 800ml, adjust the pH value of the filtrate to 6.4, and finally go through fine filtration to obtain an extract equivalent to 0.5g of Eucommia leaves per milliliter. This example was performed in laboratory glassware.

Embodiment 2

[0040] Use a 20L extraction and concentration thermal reflux unit, weigh 1500g of eucommia leaves, add 15kg of water, control the internal temperature of decoction and extraction at 98°C, start stirring during the heating process to fully mix the eucommia leaves and water, the heating time is about 1.5 hours, the highest internal temperature 98°C, start vacuum, start vacuum concentration, set inner tank temperature to 75°C, jacket temperature to 80°C, control inner tank temperature to 58°C when entering normal concentration, actual temperature to 54-55°C, vacuum degree to 0.09MPa, vacuum decompression The whole time of concentration is 2 hours, the impurity is removed during the feeding process, the filtrate is adjusted to PH6.0-6.5, and finally fine filtration and concentration adjustment are carried out. The thermal measurement specific gravity is 1.20-1.25, and 3200ml of eucommia leaf extract is obtained (each milliliter of this solution is equivalent to eucommia leaf 0.5g)....

Embodiment 3

[0042]Weigh 208.34 kg of eucommia leaves, put them in a 3 cubic multi-functional extraction tank, add 1600 kg of water for the first time, extract at a temperature of 98-100 ° C, and extract for 1 hour, add 500 kg of water for the second time, extract at a temperature of 98 ° C, and extract for 45 °C minutes, add 500kg of water for the third time, the extraction temperature is 98°C, and the extraction time is 30 minutes. Combine three decoction extracts, the total weight of the filtered extract is 2250kg, and pump the 2250kg extract into the vacuum decompression concentrator (single-effect concentrator) to control the vacuum pressure of the inner tank to 0.08-0.086MPa, temperature control 58 ℃, interlayer steam pressure 0.2MPa, when concentrated to half of the original volume, the weight of the feed liquid is 1125kg, the thermal measurement specific gravity is 1.12, the pH is adjusted to 6.4, and after fine filtration, it is concentrated under reduced pressure until the weight ...

Abstract

The invention belongs to the field of extraction of active ingredients from plants, and in particular relates to a eucommia leaf extract and a preparation method and application thereof. The eucommia leaf extract is prepared by decocting eucommia leaf in water, filtering and adjusting the pH of filtrate to be between 5.5 and 7.5. The eucommia leaf extract has the advantages of simple preparation method, capability of obviously improving the number of live bacteria in fermentation liquor and obvious effect when applied to a lactobacillus fermentation culture accelerator.

Description

(1) Technical field [0001] The invention belongs to the field of extraction of effective plant components, and in particular relates to an extract of eucommia leaves and its preparation method and application. (2) Background technology [0002] With the improvement of human living standards, people pay more and more attention to the improvement of the quality of life and the prevention and health care of diseases. Among them, various probiotics mainly lactic acid bacteria are widely used in various fields such as medicine, food, dairy products and animal feed additives. [0003] At present, drinking of lactic acid bacteria is widely prevalent in countries all over the world, but its stability is not good. The artificial culture medium with the main nutritional components) is processed into various forms of active lactic acid bacteria products, also known as "probiotic" products, together with milk powder, lactose, starch and other auxiliary materials and excipients. In cli...
