Embodiment 1

[0068] Example 1 Effect of Different Binders on the Forming of Fruit and Vegetable Paper

[0069] The purpose of adding binders in the production process of fruit and vegetable paper is to act as a bonding and supporting skeleton to improve the physical properties of fruit and vegetable juices, making the original loose fruit and vegetable juices easy to form. Different binders have different roles and effects in the fruit and vegetable paper forming process due to their different chemical components.

[0070] The inventor took the preparation of apple fruit paper as an example to study the effects of different binders in the forming of fruit and vegetable paper. First, prepare concentrated apple juice with the same water content, and the concentration of apple juice is carried out with reference to known techniques in the art, such as vacuum concentration, freeze concentration, reverse osmosis concentration, etc., vacuum concentration is used in the present invention. Acco...

Embodiment 2

[0077] The conversion of protopectin in embodiment 2 apple pomace

[0078] According to reports, apple pomace contains about 15% pectin, and the inventor imagines to use apple pomace to replace commodity pectin to prepare fruit and vegetable paper. Taking the preparation of apple fruit paper as an example, the experimental process is as follows:

[0079] 1. Preparation of raw and auxiliary materials:

[0080] The raw and auxiliary materials include the following components: 40kg 3 times concentrated apple juice and 60kg apple pomace.

[0081] 2. Apple pomace pretreatment: take fresh apple pomace, add 2 times the weight of drinking water, use a beater for beating, the speed of the beater is 20000rpm, and the beating time is 5min to obtain apple pulp;

[0082] 3. Add the concentrated apple juice to the above-mentioned apple pomace, mix thoroughly to obtain a mixed slurry, and apply the mixed slurry evenly on the glass panel with a thickness of 0.5cm, and dry it with hot air....

Embodiment 3

[0092] The preparation of embodiment 3 apple fruit paper

[0093] In order to further improve the sensory quality of fruit and vegetable paper, taking the preparation of apple fruit paper as an example, the preparation process was further optimized, mainly including the following steps:

[0094] 1. Preparation of raw and auxiliary materials:

[0095] The raw and auxiliary materials include the following components: 40kg 3 times concentrated apple juice and 60kg apple pomace.

[0096] 2. Apple pomace pretreatment:

[0097] (1) Beating: Add 2 times the weight of drinking water to the apple pomace, use a beater for beating, the speed of the beater is 20000rpm, and the beating time is 5min;

[0098] (2) homogenization: adopt high-shear homogenizer to carry out homogenization to apple pulp, high-shear homogenizer rotating speed 15000rpm, homogenization time 4min;

[0099] (3) Boiling: Boil the homogenized apple pulp in a slightly boiling state to fully decompose the protopecti...

Abstract

The invention belongs to the technical field of food processing, and discloses the use of apple pomace as an auxiliary material in preparing fruit and vegetable paper. The invention converts the original pectin rich in apple pomace into pectin, so that paper forming can be achieved without adding any other food additive that acts as a binder, in the preparation of the fruit and vegetable paper. The invention also discloses a method for preparing fruit and vegetable paper by using apple pomace, the preparation method comprises the following steps: preparing raw and auxiliary materials, apple pomace pulping, homogenizing, boiling, sieving, preparing apple pulp, blending concentrated juice or vegetable juice with apple pulp, forming and the like. The preparation process of the invention doesnot need to add any other binder or chemical additive, on one hand, the problem that other binders produce unpleasant gum taste due to drying is solved, and on the other hand, the prepared fruit and vegetable paper is safe and reliable because the product does not contain additional additives, and the label is clean and more acceptable to consumers.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to the application of apple pomace in the preparation of fruit and vegetable paper, and a preparation method of the fruit and vegetable paper. Background technique [0002] Fruit and vegetable paper is a kind of paper-like food prepared from fruit or vegetable juice as the main raw material, adding appropriate auxiliary materials, beating, rolling, and drying. It can retain the original flavor and color of fruits and vegetables, and Low moisture content, long shelf life, convenient storage and transportation, etc., as a new type of deep-processed fruit and vegetable product, has become a hot spot in the research of the food industry. The production process of fruit and vegetable paper generally includes raw material pretreatment - beating - blending - forming and drying - finished product packaging and other processes. In this process, the addition of binder-base...
