Embodiment 1

[0026] Follow the steps below to prepare 100% grape juice:

[0027] Step 1) Select suitable varieties of fresh grape fruit bunches, first put the fresh grape fruit bunches into flowing clear water to rinse for 40 seconds, then soak the washed grape fresh fruit bunches in 0.1% TD powder aqueous solution for bubble cleaning for 30 minutes. Then the fresh grape fruit bunches after air bubble cleaning are rinsed with clear water to complete the cleaning work, and then the stems on the fresh grape fruit bunches are removed to obtain grape fruit particles; in this example, the grape fruit Grains are composed of 80% summer black grapes, 5% kyoho grapes and 15% jasmine grapes;

[0028] Step 2) Carry out the primary extraction and primary filtration treatment of the grape fruit in sequence with a filter mesh number of 60 to obtain the separated grape juice A and peel and meat scraps (without grape seeds); then the obtained grape juice A is stored in in a temporary storage container fo...

Embodiment 2

[0034] Follow the steps below to prepare 100% grape juice:

[0035] Step 1) Select the fresh grape fruit bunches of suitable varieties, put the fresh grape fruit bunches into flowing clear water and rinse them for 50 seconds, then soak the fresh grape fruit bunches after washing in 0.2% TD powder aqueous solution for 25 minutes, and press them tightly. Then the fresh grape fruit bunches after air bubble cleaning are rinsed with clear water to complete the cleaning work, and then the stems on the fresh grape fruit bunches are removed to obtain grape fruit particles; in this example, the grape fruit Grains are composed of 80% summer black grapes, 10% Kyoho grapes and 10% jasmine grapes;

[0036] Step 2) Carry out the primary extraction and primary filtration of the grape fruit in sequence with a filter mesh number of 50 to obtain separated grape juice A and peel meat scraps (without grape seeds); subsequently, the obtained grape juice A is stored in in a temporary storage conta...

Embodiment 3

[0042] Follow the steps below to prepare 100% grape juice:

[0043] Step 1) Select the fresh grape fruit bunches of suitable varieties, put the fresh grape fruit bunches into flowing clear water and rinse them for 60 seconds, then soak the fresh grape fruit bunches after washing in 0.3% TD powder aqueous solution for 25 minutes, then press them tightly. Then the fresh grape fruit bunches after air bubble cleaning are rinsed with clear water to complete the cleaning work, and then the stems on the fresh grape fruit bunches are removed to obtain grape fruit particles; in this example, the grape fruit Grains are composed of 65% summer black grapes, 15% Kyoho grapes and 20% Jasmine grapes;

[0044]Step 2) Carry out the primary extraction and primary filtration of the grape fruit in sequence with a filter mesh number of 70 to obtain the separated grape juice A and peel and meat scraps (without grape seeds); then the obtained grape juice A is stored in in a temporary storage contai...

Abstract

The invention discloses 100% grape juice and a production method thereof. The production method comprises the following production steps: thoroughly cleaning a proper variety of fresh grape clusters and removing stalks to obtain grape grains; carrying out primary squeezing and primary filtration on the grape grains sequentially to obtain grape juice A and a broken peel and pulp material; performing secondary squeezing and secondary filtration on the quick-frozen broken peel and pulp material sequentially to obtain pulp and peel residues; mixing the pulp in the grape juice A, and performing sterilization to obtain grape juice B; putting the peel residues in an extracting solution for low-temperature vacuum extraction treatment to prepare grape flavor condensed liquefied water; mixing the obtained grape juice B, grape flavor condensed liquefied water, concentrated grape juice and reconstituted water according to a specific formula to prepare a blended liquid; and after sterilizing and cooling the blended liquid, conducting aseptic filling to obtain the 100% grape juice. The production method is novel and reasonable, the prepared 100% grape juice has the characteristics of strong andnatural grape aroma, sufficient color and juice, and the grape pulp yield is also effectively increased.

Description

technical field [0001] The invention relates to the technical field of beverage products, and specifically provides 100% grape juice and a preparation method thereof. Background technique [0002] At present, grape juice drinks on the market are generally made by diluting concentrated grape juice with water and reducing it. However, during the processing of concentrated grape juice, many materials rich in various nutrients, such as peel and pulp, will be discarded, which will not only cause waste of resources, but more importantly, will cause the loss of grape juice fragrance, weak taste, and overall Sensory quality is poor. [0003] In view of this, the present invention is proposed. Contents of the invention [0004] In order to overcome the above defects, the present invention provides a kind of 100% grape juice and its preparation method. The preparation method is novel and reasonable, which not only makes the prepared 100% grape juice have rich and natural grape aro...
