Problems solved by technology

[0006] The most widely used guava product is guava fresh fruit, which has sufficient raw materials, low price, and is not convenient for storage. The young fruit in the production process is usually discarded and cannot be fully utilized. Flavor substances are easily destroyed and the extraction rate of active ingredients is low. At present, guava tea products are mainly limited to primary products such as direct drying and grinding of guava and shredded guava fruit. These products have the following problems: (1) Active ingredients The extraction rate is low, and a large amount of active ingredients are discarded with plant residues, causing serious waste; (2) The solubility of flavor substances and active ingredients is low, and there are few soluble substances, so it is difficult for the human body to effectively absorb and utilize them
(3) Inconvenient to carry and use, not conducive to storage

Embodiment 1

[0028] Adopting 30 kilograms of fresh guava young fruits provided by Zhongshan Cuishan Tea Garden Co., Ltd. as raw material, the preparation process of guava instant tea is as follows:

[0029] A. Preparation of extract

[0030] Wash the fresh young guava fruit with distilled water and crush it to 100 mesh with a pulverizer. Add 30 times the weight of the young guava fruit and soak it in distilled water for 30 minutes. The extractor was intensively extracted at room temperature for 30 minutes, then heated to 80°C and extracted for 1 hour under stirring at 120r / min, and centrifuged at 2000r / min for 30 Separate and collect the filtrate in minutes; add the same 30 times distilled water to the filter residue, repeat the above process and extract twice, centrifuge and combine the filtrate, and keep the filter residue for preparing animal feed. The filtrate was concentrated to 15% of the original volume with a RE-5220 rotary evaporator from Shanghai Yarong Biochemical In...

Embodiment 2

[0037] Using 60 kilograms of dried guava young fruit shreds provided by Zhongshan Cuishan Tea Garden Co., Ltd. as raw material, the preparation process of guava instant tea:

[0038] A. Preparation of extract

[0039] Grind the dried guava young fruit shreds (cleaned before the preparation of the shreds) to 60 mesh with a pulverizer, add 4 times the distilled water according to the ratio of liquid to material and soak for 1 hour. During the soaking process, use Jining Hengsheng Ultrasonic Machinery Co., Ltd. The pilot-scale ultrasonic extractor was used to strengthen the extraction at room temperature for 60 minutes, and then heated to 100°C and extracted for 4 hours under stirring at 120r / min. Xiangtan Centrifuge Co., Ltd. IL300-N vertical centrifugal discharge centrifuge 2000r / min Centrifuge under the condition of min for 30 minutes to separate and collect the filtrate; add distilled water with a liquid-to-material ratio of 4 times to the filter residue, repeat the above pro...

Embodiment 3

[0046] Adopt Zhongshan Cuishan Tea Garden Co., Ltd. to provide 1000 kilograms of fresh guava young fruit shreds as raw material, the preparation process of guava instant tea:

[0047] A. Preparation of extract

[0048] After cleaning the young fresh guava fruit with distilled water, use a pulverizer to powder it to 70 mesh, add 15 times of distilled water according to the ratio of liquid to material and soak it for 3 hours, and then put it in a HPP. High-pressure processing equipment extracted at room temperature 500mPa for 2 hours under high-pressure process, and used Xiangtan Centrifuge Co., Ltd. IL1000-N vertical centrifugal discharge centrifuge under the condition of 1200r / min for 30 minutes to separate and collect the filtrate; add 15 times distilled water to the filter residue and repeat the above The process is extracted once more, filtered and combined with the filtrate, and the filter residue is reserved for the preparation of animal feed. Concentrate the filtr...

Abstract

The invention provides a highly clear and instant psidiumguajava tea and a preparation process, wherein the tea is produced by mainly adopting fresh or dried young fruit psidiumguajava as a raw material, and has characteristics of convenient production and taking, high safety and no toxic-side effect. According to the present invention, the fresh or dried young fruit psidiumguajava is mainly adopted as the raw material, and cleaning, grinding, ultrasonic enhanced solvent extraction, concentration, purity removing, membrane separation and enrichment, paste forming, spray drying and granulation are performed to obtain the instant psidiumguajava tea; compared with the previous psidiumguajava tea product, the product of the present invention and the preparation process thereof have the following characteristics that: the psidiumguajava fruit, especially the young fruit discarded in the production process is adopted as the raw material to change waste into treasure and obtain the instant psidiumguajava tea product; the psidiumguajava young fruit water extract has a good clinical blood sugar lowering effect, and the preparation process has characteristics of high product yield, low preparation cost, more flavor substance maintaining, and the like; and the highly clear and instant psidiumguajava tea has characteristics of convenient taking, high nutrition and high active ingredient content.

Description

[0001] technical field [0002] The invention relates to a solid instant tea product prepared from natural plants, especially guava as a raw material and a preparation process thereof. Background technique [0003] Guava ( Psidiumguajava ) is Myrtaceae (Myrtaceae ) Guava ( Psidium ) tropical evergreen perennial fruit trees. Guava fruit is rich in nutrition, rich in protein, lipid, Va, Vc and fiber, as well as trace elements such as phosphorus, potassium, calcium and magnesium. [0004] At present, the research on guava mainly focuses on cultivation, composition research and pharmacological activities. In terms of cultivation, the first variety cultivated in Taiwan - Pearl Guava, can bear fruit 5 times a year, and the annual yield per mu can reach as high as 5 tons. Guava is widely planted in my country's Taiwan, Guangdong, Guangxi and other places, and its varieties are mainly pearls, followed by carmine. Since the main ripening season of guava is August-September, th...
