Abstract
The invention discloses an organic high-efficiency oxygen absorbent for solving the technical problems that the import of the existing inorganic oxygen absorbent is prohibited and the oxygen absorption speed of the oxygen absorbent is too fast. The oxygen absorbent mainly contains the following components by weight percent: 10%-40% of ascorbic acid derivative, 11%-60% of salt, 20%-35% of silica gel and 1%-4% of a water absorbing material. In comparison with the existing oxygen absorption products, the organic high-efficiency product is stronger in oxygen absorption capacity and high in unit oxygen uptake, can prepare various oxygen absorption products, such as the universal type oxygen absorption product, the dry type oxygen absorption product, the high-energy type oxygen absorption product and the high-humidity type oxygen absorption product, and can be used widely.
Description
Technical field
The present invention relates to a kind of preparation of efficient organic oxygen absorbent, belong to oxygen uptake Plugging Technology Applied field, can be used for food fresh keeping, product is sealed up for safekeeping.
Background technology
Research and the application of oxygen absorbent have been carried out for nutrition, local flavor and the commodity value people of long-term maintenance food.According to statistics, nearly 52% is processed food in the food, 48% is perishable items, nearly all food all needs packing in varying degrees, and the upper end spaces of packing, have about 21% free oxygen, these oxygen may cause food spoilage, rotten, mildew, infested, become and fade and present peculiar smell.In order to suppress food spoilage, once adopted some chemistry and physical method, such as bactericide, anticorrisive agent and the antioxidant of chemical method; The gas displacement of Physical, vacuum packaging, infrared high frequency or microwave disinfection, ultraviolet ray or radioactive ray processing etc.; In addition, also once adopted the gas method for disinfection such as ozone.Above-mentioned all methods have certain effect, but can not break away from eventually oxygen to the impact of food, for example the displacement of vacuum packaging or inert gas is difficult to reach the food desired deoxidation degree of never degenerating, in general, packing through vacuum or gas displacement processing, still contain 2 ~ 5% oxygen, this just is enough to cause the breeding of Food Oxidation and microorganism and insects.Especially in recent years, people were to the more and more sensitivity of the use of additive, and some anticorrisive agent is disabled.Also some food preservation method to be to reduce nutrition and local flavor prolongs storage time, therefore, and can not be satisfactory.Utilize oxygen absorbent to pack except the oxygen in the unlap with food, can reach the purpose of satisfied preservation food.
Initial oxygen absorbent is mainly take iron powder as the oxygen uptake basic material, add in addition the reactive group that salt is made into, its water content is no more than 35%, add the level that the actual oxygen absorbed of product unit that oxygen uptake composition iron powder is made into reaches with this reactive group and be about 100 ~ 125ml/g, oxygen absorption rate is too fast, cause loss occurs in compound process, reduced product ability to take oxygen in use.Simultaneously in recent years American-European countries's nonimportation inorganic iron is oxygen absorbent, so that we must seek a kind of oxygen-absorbing material in addition, to avoid iron powder as the prescription of main body.
Summary of the invention
The objective of the invention is provides the efficient organic oxygen absorbent for inorganic oxygen absorbent embargo and the too fast technical problem of oxygen absorbent oxygen absorption rate.Wherein the main oxygen uptake composition of organic oxygen absorbent is ascorbic acid (L-VcNa), and its mechanism of action mainly is in the presence of the metal ion of trace, under the effect of low-grade fever or light, accelerates the oxidation of sodium ascorbate.The sodium ascorbate that the present invention adds mainly is L-AA sodium, it is characterized in that stablizing under the drying regime, reaches eremacausis decomposition in the aqueous solution after the moisture absorption, thereby reaches the purpose of oxygen uptake.And D-sodium ascorbate and L-AA sodium are relatively, and heat resistance is relatively poor, and oxidation resistance is stronger, therefore are not easy the purpose that oxidation reaches oxygen uptake.
Purpose of the present invention can reach by following measures:
A kind of efficient organic oxygen absorbent comprises ascorbic acid derivates, salt, silica gel and absorbent material, and wherein the mass content of each component is:

Three, this oxygen absorbent comprises the component by following mass content proportioning: ascorbic acid derivates 5% ~ 30%, and salt 15% ~ 35%, silica gel 15% ~ 60%, white carbon 0.5% ~ 3%, adsorption moisture 15%～45% in the white carbon.Each component summation is 100%.
Four, this oxygen absorbent comprises the component by following mass content proportioning: ascorbic acid derivates 15% ~ 30%, salt 13% ~ 45%, silica gel 15% ~ 50%, hydroscopic high-molecular resin and diatomite 1% ~ 6%; Wherein hydroscopic high-molecular resin and diatomaceous mass ratio are 1.5:1, and adsorption moisture 15%～45% in hydroscopic high-molecular resin and the diatomite.Each component summation is 100%.
Ascorbic acid derivates in the prescription is basic oxygen uptake composition, the preferred sodium ascorbate that adopts, purity requirement is greater than 99.8%, require particle generally greater than 60 orders, here the sodium ascorbate of usefulness can only be L-type (being L-type ascorbic acid sodium), can't being effective of experimental verification D-type, effect was not good yet when impurity was many simultaneously.
Other compositions in the prescription are the anabolic reaction base, and wherein salt is selected from one or more in sodium carbonate, sodium acid carbonate, calcium hydroxide, sulphite or the sulfate, can independent or by a certain percentage composite use.Wherein sulphite or sulfate can be sodium sulfite, sodium sulphate, potassium sulfite.
The silica gel particle diameter can be used for eliminating peculiar smell and reaction speed greater than 300 orders, and its consumption can be selected according to requirements, and reaction speed is accelerated with the consumption of silica gel usually.
Absorbent material has very strong water absorbing capacity, the use of can using separately or arrange in pairs or groups; Material is selected from one or more in diatomite, hydroscopic high-molecular resin, the white carbon.Wherein hydroscopic high-molecular resin is Sodium Polyacrylate.
Beneficial effect
It is strong that efficient organic oxygen absorbent provided by the invention and existing oxygen uptake product relatively have an ability to take oxygen, and the unit oxygen absorbed is high, can prepare universal, drying type, high energy type, the multiple oxygen absorbent product of high wet type, and of many uses, advantage is obvious.
