Problems solved by technology

However, even with the pulp prepared by this method, there is a problem that when pasteurized, the pulp becomes softer than the pulp before heating.
In addition, for the production method of jelly containing vegetables and fruits, there are methods of separately preparing a dispersion liquid in which solid matter of vegetables and fruits is put in a liquid containing calcium and dissolving low-methoxyl pectin etc. in a liquid containing calcium. The liquid formed in the liquid is then mixed, and it is mixed with a raw material liquid containing a gelling agent and a thickening polysaccharide and cooled to make it harden (Patent Document 7), but it is limited to the production method of jelly, And the method of suppressing the softening of the fruit is not combined with the peeling process of the raw material
There are Patent Document 8 and Patent Document 9, which utilize the reduction of methyl esterification of pectin (methylesterase activity), but the object of Patent Document 8 is not root vegetables and citrus, but heat treatment is used as a condition for activating PME , is a cumbersome process and is not combined with the peeling process

preparation example 1

[0083] (Preparation example 1) the preparation of the pulp flap with endothelium

[0084] In order to examine the effect of the present invention on preventing softening of the pulp after peeling, a flesh flap with an inner skin from which the outer skin has been removed (distributed pulp flaps broken into flaps) was prepared.

[0085] (a) Sample

[0086] U.S. and South African grapefruit (white-flesh and red-flesh varieties) were used as raw material fruits, and Viscozyme L (Novozymes Japan) was used as an enzyme preparation.

[0087] (b) method

[0088] Grapefruit (hereinafter GF) was perforated using a sharp drill (approximately 50 places on the fruit body). The fruit subjected to the porosity treatment was dipped in a Viscozyme L 0.20% by mass aqueous solution of twice the fruit weight, and the dipping process was performed under reduced pressure at 720 mmHG for 5 minutes. Take out the fruit from the enzyme solution, soak in hot water at 45°C and react for 30 minutes. ...

[0089] (Example 1) Study of Enzyme Concentration (Low Temperature and Long Time Treatment Using Endothelial Pulp Flaps)

[0090] (a) Sample

[0091] The flesh flap with endothelium prepared in Preparation Example 1 from GF (white meat variety) produced in South Africa and Viscozyme L (compound plant hydrolase, Novozymes Japan Co.) were used.

[0092] (b) method

[0093] After immersing 300 g of the flesh pieces with inner skin in 300 g of enzyme aqueous solutions adjusted to the respective concentrations shown in Table 1 and reacting at 9° C. for 17 hours, the state of the pulp was observed.

Embodiment 2

[0102] (Example 2) Verification of pulp softening due to heating

[0103] (a) Sample

[0104] GF (white meat variety) from South Africa was used as a raw material fruit, and Viscozyme L (Novozymes Japan Co., Ltd.) was used as an enzyme preparation.

[0105] (b) method

[0106] The pulp in the non-heating zone is obtained by cutting the outer skin of GF with a kitchen knife, peeling off the outer skin by hand, and breaking it into flaps, so as to obtain each pulp flap with inner skin. The inner skin is cut and separated from the pulp with a kitchen knife appropriately to obtain the pulp from which the inner skin has been removed. The pulp in the heating zone is obtained by using the method shown in Preparation Example 1 to obtain each pulp flap with inner skin. 2000 g of the inner skin-attached pulp pieces were immersed in 2000 g of Viscozyme L 0.20% by mass aqueous solution, and reacted at 9° C. for 17 hours to obtain pulp from which the inner skin was removed. The pulp wa...

Abstract

The present invention provides a composition for processing used to remove the endodermis from a citrus fruit and prevent softening of pulp, and a processing method using the same. A citrus fruit pulp from which the endodermis has been removed and in which softening has been prevented is obtained by performing a processing treatment comprising treatment for three hours or longer or 15 hours or longer at a low temperature of less than 20 DEG C in a state of contact between endodermis and a composition for processing citrus fruit pulp. The composition is characterized by including at least one enzyme selected from the group consisting of cellulase enzyme, pectinase enzyme, and hemicellulase enzyme, pectin methyl esterase enzyme, and calcium.

Description

technical field [0001] The invention relates to a processing method of citrus fruits. Background technique [0002] The raw materials of citrus fruit processed products have to go through processing procedures such as peeling and heat sterilization. These treatments at the time of processing cause softening of the pulp, and there is a problem of impairing the original texture and freshness of the raw material. A treatment method using an enzyme that minimizes damage to pulp has been invented for peeling citrus fruits (Patent Document 1). However, even the pulp prepared by this method has a problem that, when heat-sterilized, the pulp becomes softer than the pulp before heating. [0003] It is known that when vegetables and fruits are treated with an aqueous solution or the like containing salts such as calcium, physical properties become hard. In the existing patent documents utilizing it, there are the following methods: after immersing vegetables in a calcium aqueous so...
