Abstract

The invention provides a composite food preservative, which comprises (by weight percent): benzoic acid 10-12%, potassium sorbate 15-17%, p-hydrocarbyl benzoate 35-40% and dehydroacetic acid 33-38%.

Description

Composite food preservatives

(1) technical field

What the present invention relates to is a kind of anticorrisive agent, specifically a kind of food preservative.

(2) background technology

Along with the fast development of China's food industry, because Long-term Storage, long-distance transport and the seal-packed needs of food, food antiseptic has become the major issue in the development of food industry.The use of anticorrisive agent not only can prolong the storage period and the shelf life of food, but also can prevent to produce in the food harm of malicious microorganism, and food preservative has been brought into play huge effect to the development of food industry thus.

But because the diversity of food, single food preservative is very little to the food antiseptic functionality, and do not reach the effect of food antiseptic, thereby food preservative also just is faced with new selection, it is current to base oneself upon tool, develop new complex food aseptic technic, the direction of research that Here it is with fundamental change.

What China used for a long time is the anticorrisive agent of single composition mostly, for example Sodium Benzoate, potassium sorbate, calcium propionate, sodium propionate, to the alkyl ethyl benzoate, to alkyl benzoic acid second propyl ester, to alkyl benzoic acid second butyl ester, dehydro sodium acetate etc.

Any anticorrisive agent of single use all can not all have killing effect to the fungi in the food, bacterium, saccharomycete etc.The medicament of the sterilization that all use in food also can not only be killed a kind of bacterium.That is to say that various bactericide all have certain fungicidal spectrum.The bacterium that contains in a kind of food, not a kind of sometimes anticorrisive agent can both suppress.

(3) summary of the invention

The object of the invention is to provide between a kind of each composition cooperative effect takes place, and food is had the composite food preservatives of good antisepsis.

The object of the present invention is achieved like this: it is benzoic acid 10-12%, sorbic acid 15-17%, alkyl benzoic ether 35-40% and dehydroactic acid 33-38% is formed by weight ratio.

Wherein benzoic acid can be a Sodium Benzoate; Sorbic acid can be a sodium sorbate; To the alkyl benzoic ether can be to the alkyl ethyl benzoate, to alkyl propyl benzoate, any in the alkyl butyl benzoate; Dehydroactic acid can be the deoxidation sodium acetate.

In theory, the be mixed fungicidal spectrum that uses of two or more anticorrisive agents is different with the fungicidal spectrum of single anticorrisive agent, the bacterium that the anticorrisive agent of the use that therefore is mixed just can suppress the untamed mushroom of a kind of anticorrisive agent or need could suppress under high concentration very.Several anticorrisive agents are mixed to use following three kinds of possibilities on antibacterial ability.

First kind: additive effect, i.e. the effect of each one matter, simply together.

Second kind: cooperative effect, also claim synergy, the effect that is meant mixture significantly improves than the effect of one matter, and the valid density of each medicament all significantly reduces than independent working concentration in composite food preservatives in other words.

The third: the resistive connection effect, be meant the effect opposite with cooperative effect, promptly the inhibition concentration of mixture is significantly higher than the concentration of single component.

Listed in the table 1 and used the inhibitory action of single food preservative microorganism in the food

Listed compound preservative of the present invention in the table 2 to action of microorganisms in the food

From table 1, table 2 as can be seen, have only exploitation and use new change preservative technology with essence, could satisfy the requirement of development of food industry, situation according to China, must be based on current, look forward to the future, just reasonably the existing food antiseptic technology of integrated use is studied the new invention technology with fundamental change again.

A kind of food can be regarded an ecosystem as, increasing of a certain anticorrisive agent addition of single use, though reach the corrosion-resistant purpose, but make inside of food and organoleptic properties all be subjected to destruction, comprehensive corrosion protection system then is to utilize the various factors that can influence this ecosystem, although which is not fierce, the long and is the activity of having prevented harmful bacterium, has reached anticorrosion preferably purpose and effect.

With regard to the thick broad-bean sauce in the sauce based food, the any anticorrisive agent of single use is tested through several times, in the scope of application of national regulation or the addition that uses of overshoot, add in the thick broad-bean sauce, then with packaging bag vacuumize pack after, all do not control saccharomycetic secondary fermentation through experiment, the gas that rises of packaging bag as a result, and use composite food preservatives of the present invention, and in using addition, national regulation do not find to rise a bag phenomenon, control saccharomycetic regrowth effectively.

Compound preservative of the present invention, to the security of food antiseptic, and food is in color, shape and the nutrition of duration of storage, and fruit, Vegetable Preservation can both play important effect.

(4) specific embodiment

For a more detailed description to the present invention for example below in conjunction with accompanying drawing:

Be benzoic acid 10-12%, sorbic acid 15-17%, the ratio of alkyl benzoic ether 35-40% and dehydroactic acid 33-38% is mixed each raw material according to weight ratio, packing is made product.Wherein benzoic acid is a Sodium Benzoate; Sorbic acid is a sodium sorbate; To the alkyl benzoic ether is to the alkyl ethyl benzoate, to alkyl propyl benzoate, any in the alkyl butyl benzoate; Dehydroactic acid is the deoxidation sodium acetate.

Be benzoic acid 10%, sorbic acid 15%, the ratio of alkyl benzoic ether 40% and dehydroactic acid 35% is mixed each raw material according to weight ratio, packing is made product.Wherein benzoic acid is a Sodium Benzoate; Sorbic acid is a sodium sorbate; To the alkyl benzoic ether is to the alkyl ethyl benzoate, to alkyl propyl benzoate, any in the alkyl butyl benzoate; Dehydroactic acid is the deoxidation sodium acetate.
