preparation example Construction

[0017] The preparation method of the high-efficiency external control type antistaling agent of the present invention is,

[0018] Step 1. Take 49.995%-68% of edible alcohol and 0.005%-2% of allyl isothiocyanate by mass percentage and mix them evenly in a relatively airtight container;

[0019] Step 2, adding 30% to 50% of silicon dioxide with a particle size greater than 20 meshes, stirring and mixing the above materials at room temperature, and the stirring speed is 10 rpm to 60 rpm;

[0020] Step 3. Stir evenly to obtain the preservative, and then seal it with a moisture-permeable packaging film.

Embodiment 1

[0022] Step 1, take edible alcohol 67.99% by mass percentage, allyl isothiocyanate 0.01% and mix evenly in a relatively airtight container;

[0023] Step 2, adding 32% of silicon dioxide with a particle size of 2000 mesh, stirring and mixing the above materials at room temperature, and the stirring speed is 60 rpm;

[0024] Step 3. Stir evenly, press into tablets to obtain the antistaling agent, and then package it with a moisture-permeable packaging film; or add a layer of moisture-permeable film on the pressed sheet-shaped antistaling agent.

Embodiment 2

[0026] Step 1, take edible alcohol 59.7% by mass percentage, allyl isothiocyanate 0.3% and mix evenly in a relatively airtight container;

[0027] Step 2, adding 40% of silicon dioxide with a particle size of 500 mesh, stirring and mixing the above materials at room temperature, and the stirring speed is 40 rpm;

[0028] Step 3. Stir evenly to obtain the preservative, and then package it with a moisture-permeable packaging film. The product is in the form of a three-side sealed packet, a four-sided sealed packet, a small packet chain, etc. It can also be divided into moisture-permeable pouches and then sealed.

Abstract

The invention provides a high efficient external control type antistaling agent, which, according to the percentage of the quality, is composed as the following; 30 to 50 per cent silicon dioxide, 49.995 to 68 per cent edible alcohol and 0.005 to 2 per cent allyl isothiocyanate. The antistaling agent is obtained by using the following methods: mixing the edible alcohol and the allyl isothiocyanate according to the quality percentage and then mixing with the silicon dioxide; then loading the mixture into a moisture permeability packaging film after stirring evenly under normal temperature for sealing. The invention can be used for storing food, medicinal materials, reagent, tobacco and leather. When it is used for storing food, packing the invention into packet, scraps with the moisture permeability packaging film and then placing them into the package of food to make the antistaling agent being released slowly in gas mode and being volatilized into the internal gaps, thus forming a gas phase protective layer with certain concentration around the food to be preserved, so as to effectively restrain, kill many kinds of leaf mold and bacterium as well as other spoilage organisms; besides, the invention increases the permeation pressure in the package and lowers the water activity of the food, so as to preserve the food with high efficiency.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion and fresh-keeping, and in particular relates to a high-efficiency external-control fresh-keeping agent and a preparation method thereof. Background technique [0002] The external control type preservative releases the fresh-keeping gas to volatilize into the inner space of the container, and forms a certain concentration of gas-phase protective layer around the preserved items to inhibit and kill a variety of molds, bacteria and other spoilage bacteria, so as to achieve A class of substances with fresh-keeping effect. This kind of product is mainly used for the storage of food, medicinal materials, reagents, tobacco, leather, etc., and is currently the most widely used in food preservation and preservation. It mainly consists of two parts: carrier and fresh-keeping medicine. [0003] Taking food as an example, food preservation plays an important role in human health and life safety. Scie...
