Problems solved by technology

However, since proanthocyanidins and resveratrol in grapes are mainly concentrated in grape skins and grape seeds, the content of proanthocyanidins and resveratrol in grape juice produced from grape pulp is low, and the inherent anti-tumor and anti-oxidation properties of grapes , The antiviral effect is greatly limited, and commercially sold grape juice drinks are often made by blending grape juice with a large amount of saccharin and water, which not only lacks the original flavor and fresh fruit flavor, but also contains preservatives and pigments , grape essence and other chemical ingredients, long-term drinking will have adverse effects on health

Embodiment 1

[0011] (1) Choose fresh thorn grapes as raw materials, rinse with clean water, and drain. Use a high-speed tissue homogenizer to crush at a speed of 10,000r / min for 5 minutes; (2) Process the homogenate at 80°C for 4 minutes, and immediately put it in the refrigerator to cool; (3) Place the homogenate after color protection at 400W (4) Treat the ultrasonically treated homogenate in a 600W microwave field for 45 minutes; (5) Squeeze: use a squeezer to squeeze out the juice; (6) Clarify the obtained juice with 4 layers of gauze Filtrate; centrifuge at 8,000 r / min for 15 minutes to obtain thorn grape juice; (7) Sterilize and fill, place the thorn grape juice in a 1000W microwave field for 1 minute, cool, repeat 3 times, and aseptically fill .

[0012] According to HPLC detection, the OPC content of the prepared prickly grape juice was 46.76 mg / mL, and the Res content was 8.19 μg / mL. After microbiological testing, the prepared prickly grape juice met the national standard (the n...

Embodiment 2

[0014] (1) Crush the washed thorny grapes at 12,000 r / min for 5 minutes; (2) Protect the color at 80°C for 4 minutes and cool; (3) Treat the color in a 600W ultrasonic field for 25 minutes; (4) Ultrasonic treatment Homogenize in a microwave field of 800W for 45min; (5) Squeeze; (6) Filter the juice with 4 layers of gauze and centrifuge at 8000 r / min for 15min to obtain the original thorn grape juice; (7) Put the original thorn grape juice in a 1000W Treat in a microwave field for 1 min, cool down, repeat 3 times, and aseptically fill.

[0015] According to HPLC detection, the OPC content of the prepared thorn grape juice was 49.64 mg / mL, and the Res content was 9.37 μg / mL. After microbiological testing, the prepared prickly grape juice met the national standard.

Embodiment 3

[0017] (1) Crush the washed thorny grapes at 10,000 r / min for 5 minutes; (2) Protect the color at 85°C for 4 minutes and cool; (3) Treat the color in a 400W ultrasonic field for 15 minutes; (4) Ultrasonic treatment Process the homogenate in a microwave field of 1000W for 45min; (5) Squeeze; (6) Filter the juice with 4 layers of gauze and centrifuge at 10000 r / min for 15min to obtain the original thorny grape juice; (7) Place the original thorny grape juice at 1000W Treat in a microwave field for 1 min, cool down, repeat 3 times, and aseptically fill.

[0018] According to HPLC detection, the OPC content of the prepared thorn grape juice was 46.28 mg / mL, and the Res content was 9.66 μg / mL. After microbiological testing, the prepared prickly grape juice met the national standard.

Abstract

The invention discloses a preparation method of vitis davidii normal juice rich in resveratrol and procyanidine. The preparation method comprises the following steps of: (1) homogenizing; (2) color protection, namely, after homogenizing, immediately carrying out color protection for 4-6 minutes at 80-85 DEG C; (3) ultrasound, namely, carrying out 300-600W ultrasound treatment for 15-30 minutes; (4) microwave, namely, carrying out 400-1000 W microwave treatment for 45-60 minutes; (5) squeezing; (6) clarifying, namely, after filtering by two to four layers of gauze, centrifuging for 15-20 minutes at the speed of 8000-1000r / min, wherein upper clear liquid is the vitis davidii normal juice; and (7) sterilizing and filling, namely, carrying out 1000-1200W microwave treatment on the vitis davidii normal juice for 1-3 minutes, cooling, repeating for 3-4 times, and finally carrying out aseptic filling. The vitis davidii normal juice prepared by the method is rich in resveratrol and procyanidine and has very good healthcare effect on human bodies after being drunk for a long term. The vitis davidii normal juice does not contain any additives, is safe to drink and has no harmful effects on the human bodies.

Description

technical field [0001] The invention relates to a method for preparing thorny grape juice rich in resveratrol and proanthocyanidins, in particular to a method for preparing thorny grape juice with ultrasonic-microwave assistance. Background technique [0002] Thorn grape (Vitis davidii Foex.), also known as mountain grape and jack vine, is a species under the East Asian group of Vitis vinifera. Its branches are covered with sharp thorns, so it has natural resistance to diseases and insect pests. For a long time, thorny grapes have been distributed in Hunan, Hubei, Guangxi, Sichuan and other regions in my country in a wild state. Traditional medicine believes that thorn grapes have the functions of promoting qi and blood circulation, eliminating accumulation and relieving pain, and have a good curative effect on muscle and bone injuries, abdominal distension and other symptoms. Modern medicine has found that thorn grapes are rich in proanthocyanidins (OPC) and resveratrol (R...
