JPS60149368A - Production of fruit juice of kiwi fruit - Google Patents

Abstract

PURPOSE:To obtain the titled fruit juice without containing fragments of skin, fruit hair and seeds nor pulverizing the fruit, by freezing a kiwi fruit, thawing the frozen fruit, placing the thawed fruit between pieces of filter cloth, and pressurizing the fruit slowly in a press. CONSTITUTION:A kiwi fruit is preferably frozen slowly at -20-+30 deg.C and thawed. The thawed fruit is then placed between pieces of filter cloth and pressurized slowly (for example, under a pressure as low as 0.3-0.5kg/cm<2> to 3- 5kg/cm<2>) to press out, separate and afford the aimed fruit juice.

Description

[Detailed Description of the Invention] Kiwifruit has brown skin and green flesh? It is a fruit that has fine light brown hairs on the pericarp, and has slightly long black cilia on both ends of the fruit. , brush washing, alkali treatment and acid treatment also remove the fruit, and the pulp contains numerous dark brown seeds.

When the kiwifruit is squeezed, the crushed and peeled pericarp 2 and pieces of kiwifruit are mixed into the juice and cannot be easily removed. In addition, since the larvae mixed in the crushed fruit appear to be foreign substances, it is possible to remove them by centrifugation 4, but there was some opening that reduced the fruit juice yield by about 10%.

The present invention uses kiwifruit fruit? I unzip the tied sickle,
The fruit is placed between the trays and gradually pressurized with a pressure rock to extract and separate the juice, and the dried fruits are separated without being crushed, and the peel, the fruit and the 1-111 child are separated. How to make kiwifruit juice without fragments? This is what we provide.

+: Invented by Kikui fruit, American beggar, washed and frozen. The water (originally, cleaning is done using commercial pressure, water, and sterilizing agents. Freezing is done slowly to prevent temporary destruction of the material. You can make row 5 by adding OC to 30 to Frozen 4 to Φ.

Thaw can be done by straight, soaking, or dipping.

Kiwifruit rice? Freeze the frozen bite, thaw it, fix it by itself during the first press of the knife, press the knife at 0 pressure to separate the juice, and freeze it in the darkness of ≦7 drops of TF5. After the kiwifruit is thawed, the most suitable type is a filter-less type in which the thawed kiwifruit is placed and pressure is applied from both sides to zero. In addition, it is possible to use a system that combines pressurization and suction filtration, but in either case, initially θ3~θSh〃-
The fruit cells are destroyed by gradually setting from a low pressure of 3 to 5 liters, and the fruit is placed between cloths without crushing it, and the fruit is gradually pressurized with a press to extract the juice. Because of the separation, the uninvented method yields 1 juice with a pressing force of 2 to 4 times more than the 4J of untreated fruit, and when compared with the same pressing force, the uninvented method produces approximately
Achieved the squeezing rate of sound.

In addition, since the present invention does not require peeling the fruit, it is possible to shorten the time required for juicing when peeling fruit. The reason for this is not clear, but the peel and pulp of pressed fruits easily peel off, and the peel pieces that are pressed and pressed have an effect as a temporary aid between the pericarp and the vermilion pulp. This is thought to be due to the formation of

In addition, since the fruit is not crushed, the pericarp 2 and 1 seed 7al will not be broken, and therefore there is no need to separate the pericarp pieces, the fruit pieces, and the pericarp pieces more than once, and this improves the juice yield. can be kept.

The fruit juice obtained in this way is used as a raw material for beverages, while the peel and pressed pulp are contaminated with broken fruit.
By removing the peel by hand, the pulp can be separated from the raw material for jam, etc.

It is also possible to collect seeds.

Leave it for 2 hours and freeze it, then remove it and freeze it for about 7 hours.
After rinsing with a brush for 90 minutes, it was soaked in water for about an hour and frozen.

As a control example, kiwifruit that had not been frozen was squeezed. After brushing the fruit and washing it with water, the fruit becomes 390 yen.
