Embodiment 1

[0025] Example 1: (Preparation method of citrus peel residue pulp mold 1)

[0026] The method in this example is carried out as follows:

[0027] (1) Pretreatment of citrus peel and dregs: collect the peel and dregs of Wenzhou Citrus fruit in the process of processing canned syrup orange slices as raw materials, after removing impurities, rinsing and draining, for use;

[0028] (2) The rolling treatment of citrus peel residue: the distance between the two rollers 1 in the citrus peel residue rolling device with a groove 3 of 1 mm in width is sequentially adjusted to 2 mm and 0.1 mm; the raw material after step (1) pretreatment Divide into 3 parts; when the distance between the two rollers 1 is 2mm, add 2 of them to the hopper 5, and start the motor 4 to drive the roller 1 to rotate, and the raw materials are rolled into a mesh-like rolled product; When the distance is 0.1mm, use the same method as above to crush 1 part of the raw material into the finest granular compacted product, ...

Embodiment 2

[0031] Example 2: (Preparation method of citrus peel residue pulp mold 2)

[0032] In this example, step (1) collect the peels and residues of local early fruits that were discarded during the processing of canned syrup orange slices as raw materials; step (2) use the two rollers in the citrus peel and residue rolling device with groove 3 of 5mm Adjust the distance between 1 to 2mm, 1.5mm and 0.5mm in sequence; divide the pretreated raw material in step (1) into 4 parts; when the distance between the two rollers 1 is 2mm, add 2 parts of it to the hopper 5; When the distance between the rollers 1 is 1.5mm and 0.5mm respectively, add 1 part of each into the hopper 5; store the three grades 1, 2 and 4 respectively; step (3) put the three grades of citrus peel The crushed residues were degummed with 0.5% pectinase aqueous solution in a ratio of 1:10 by weight at a liquid temperature of 40°C for 10 minutes, and then stored separately; step (4) degummed the three-stage citrus peel The...

Embodiment 3

[0033] Example 3: (Preparation method of citrus peel residue pulp mold 3)

[0034] In this example, step (1) collect the peels and residues discarded during the juice processing of sweet orange fruits as raw materials; step (2) the distance between the two rollers in the citrus peel and residue rolling device with a groove 3 of 3mm in width Adjust to 2mm, 1.5mm, 1mm and 0.1mm in sequence; divide the pretreated raw material in step (1) into 5 parts; when the distance between the two rollers 1 is 2mm, add 2 of them to the hopper 5; when the two rollers When the distance between one room is 1.5mm, 1mm, and 0.1mm, respectively, add 1 portion to the hopper 5; store the four grades 1, 2, 3, and 5 respectively; 5 The four grades of compacted materials are stored separately; step (3) The four grades of citrus peel compacted materials are respectively treated with 0.3% hydrochloric acid aqueous solution at a weight ratio of 1:7 at a liquid temperature of 20°C for 100 minutes After degumm...

Abstract

The invention discloses a method for preparing a citrus peel-residue paper pulp mould and belongs to the technical field of comprehensive utilization and processing of agricultural and sideline products. The method comprises the following steps of: preprocessing citrus peel-residue raw materials, rolling citrus peel-residues, degumming the products obtained by rolling the citrus peel-residues, mixing and molding of the products obtained by rolling the citrus peel-residues and the like. In the method, the citrus peel-residues which are byproducts of the processing of citrus are used as a raw material, the surface area, the cross linking degree and the tensile strength of the citrus fibers are improved after processing, and the problems of difficult forming and poor product quality are solved; and the prepared citrus peel-residue paper pulp mould product in a sheet shape or different mould shapes can be used for inner packaging of sugars, cakes and the like and outer packages of food, and the added value of the citrus peel-residues is improved. The method can be popularized and applied to food processing enterprises.

Description

Technical field [0001] The invention relates to the technical field of comprehensive utilization and processing of agricultural and sideline products, in particular to a method for preparing various types of citrus peel residue paper pulp molds using citrus peel residue as a raw material. Background technique [0002] my country is a major producer of citrus, as well as a major producer and exporter of processed citrus products such as canned orange slices, citrus jam, and fruit juice. At present, canned orange slices account for more than 70% of the world's total output. Various types of citrus will inevitably produce 30%-40% of the total weight of citrus raw materials in the process of processing, and how to make full use of these waste citrus peels and residues containing a lot of plant fiber, can reduce environmental pollution , It can turn waste into treasure to increase the added value of citrus peel and residue, and it will also help the sustainable development of citrus i...
