Embodiment 1

[0042] Example 1 Effect of pre-cooling treatment and high-voltage pulsed electric field treatment on the content of limonin in orange juice

[0043] The following methods were used to prepare concentrated orange juice in order to screen a treatment method for reducing the production of limonin in orange juice. In this example, the raw material used is Jiangxi navel orange, which is produced in Ganzhou, Jiangxi.

[0044] Treatment group 1:

[0045] (1) Pre-cooling the navel orange, the pre-cooling temperature is 0~4℃;

[0046] (2) Wash, peel, squeeze and filter the pre-cooled navel orange to obtain orange juice;

[0047] (3) Concentrate the oranges to obtain concentrated orange juice.

[0048] Treatment group 2:

[0049] (1) Wash, peel, squeeze and filter the navel orange to obtain orange juice;

[0050] (2) The orange juice is placed in a high-voltage pulsed electric field chamber, and the high-voltage pulsed electric field treatment is performed. The electric field intensity of the high-...

Embodiment 2

[0062] Example 2 Effect of grape skin extract on vitamin C loss of navel orange fruit paper

[0063] Choose fresh, moderately mature, non-deteriorating, non-rotted navel oranges, clean and peel them to make concentrated navel orange juice for later use. The navel oranges used were purchased from a vegetable market in Hangzhou.

[0064] The preparation of navel orange fruit paper includes the following steps:

[0065] 1. Prepare raw and auxiliary materials:

[0066] The raw materials include the following ingredients: 30kg 1.5 times concentrated navel orange juice and 30kg apple pomace.

[0067] 2. Pretreatment of apple pomace:

[0068] (1) Beating: add 4 times the weight of drinking water to the apple pomace, use a beater to beat, the beater speed is 20000rpm, and the beater time is 8min;

[0069] (2) Homogenization: Use a high-shear homogenizer to homogenize the apple pulp, the high-shear homogenizer rotates at 15000rpm, and the homogenization time is 5min;

[0070] (3) Boiling: boil th...

Abstract

The invention belongs to the technical field of food processing and particularly relates to a preparation method of citrus fruit paper. The preparation method includes the steps of adopting apple pomace as an auxiliary material for replacing a binder, preparing concentrated citrus juice after pretreatment, and obtaining the fruit paper through blending and molding, wherein the concentrated citrusjuice is prepared by juicing and concentrating any one or two or more of citrus fruits such as tangerines, citrus reticulata, oranges, pomelos and lemons. The preparation process does not require theaddition of any other commercial binders or chemical additives. On the one hand, the problem that other binders generate an unpleasant glue smell due to drying is solved; on the other hand, the prepared fruit paper is safe and reliable due to the fact that the fruit paper does not contain additional additives, labels are clean, and the fruit paper is more acceptable to consumers.

Description

Technical field [0001] The invention belongs to the technical field of food processing, and specifically relates to a citrus fruit paper and a preparation method thereof. Background technique [0002] Fruit and vegetable paper is a kind of paper-like food made of fruits or vegetables as the main raw material, adding appropriate auxiliary materials, beating, rolling, and drying. It can retain the original flavor, color and moisture of fruits and vegetables. Low content, with extended shelf life, convenient storage and transportation, etc., as a new type of deep-processed fruit and vegetable product has become a major research focus in the food industry. Among them, the auxiliary materials used are usually binders, in addition to some rich flavor seasonings. The production process of fruit and vegetable paper generally includes the processes of raw material pretreatment-beating-blending-forming and drying-finished product packaging. In this process, the addition of binder-based au...
