preparation example Construction

[0033]The second aspect of the present invention provides a preparation method of a mineral composite fruit and vegetable fresh-keeping material. Firstly, the raw materials of the formula components are dried, and then the raw materials of each component are weighed and mixed according to the mass ratio, and then unloaded and packaged after mixing evenly. In an exemplary preparation method, it includes the following steps:

[0034] (1) Dry bentonite, protein clay, zeolite and lime below 150°C;

[0035] (2) Mix silica powder with dried and cooled bentonite, protein clay, zeolite and lime;

[0036] (3) The mixed mineral composite fruit and vegetable fresh-keeping material is inspected and packaged.

[0037] [use]

[0038] The third aspect of the present invention provides the use of mineral composite materials in fruit and vegetable preservation. Wherein, the mineral composite material is the material described in the first aspect. I won't repeat them here.

Embodiment 1

[0041] Based on the following formula, dry bentonite, protein clay, zeolite and lime below 150°C;

[0042] (2) Mix silica powder with dried and cooled bentonite, protein clay, zeolite and lime;

[0043] (3) The mixed mineral composite fruit and vegetable fresh-keeping material is inspected and packaged.

[0044] The mineral content of the zeolite analyzed by XRD is more than 80%, the particle size is 325 mesh sieve ≤3%, and the water content is ≤2%. The main chemical composition of lime is Ca(OH) 2 >90%, particle size 325 mesh sieve ≤3%, moisture content ≤1.0%. The content of montmorillonite in the bentonite is more than 80%, the particle size is 200 mesh sieve ≤3%, and the water content is ≤5%. SiO in silica powder 2 Content > 98%, particle size 325 mesh sieve residue ≤ 3%, moisture content ≤ 0.25%. Amorphous SiO in protein clay 2 Content > 80%, particle size 325 mesh sieve residue ≤ 3%, moisture content ≤ 1.0%.

Abstract

The invention discloses a mineral composite fruit and vegetable fresh-keeping material as well as a preparation method and application thereof. The mineral composite fruit and vegetable fresh-keepingmaterial is prepared from the following components in parts by weight: 40 to 60 parts of bentonite, 20 to 30 parts of silica powder, 10 to 20 parts of opoka, 5 to 15 parts of zeolite and 2 to 10 partsof lime. The mineral composite fruit and vegetable fresh-keeping material disclosed by the invention has higher sterilization and inhibition effects while keeping fresh.

Description

technical field [0001] The invention relates to the field of fresh-keeping of fruits and vegetables, in particular to a mineral composite fresh-keeping material for fruits and vegetables, a preparation method and application thereof. Background technique [0002] Fresh-keeping of fruits and vegetables is very important to the transportation and storage of fruits and vegetables. There are various specific methods of fresh-keeping, but they are all regulated by factors that play a key role in the quality of fresh-keeping. The first is to control its aging process, which is generally achieved through the control of respiration; the second is to control microorganisms, mainly through the control of spoilage bacteria; the third is to control internal water evaporation, mainly through the control of the relative humidity of the environment and cell To achieve the structuring of inter-moisture. [0003] Based on different principles, there are two main categories of fruit and vege...
