Abstract
The invention relates to a hydrogen charging food packaging technology. Food to be packaged, a packaging bag and an inflation packaging machine are comprised. The hydrogen charging food packaging technology has the key point that hydrogen or the mixed gas of hydrogen and nitrogen is charged into the vacuumized packaging bag by using the inflation packaging machine. In the pure hydrogen charged package, the charging amount is not smaller than 10 percent of the volume of packaged food; and in the hydrogen and the nitrogen mixed gas charged package, the mixed gas comprises larger than 10 percent of hydrogen and the balance of nitrogen in volume proportion. The package, charged with the hydrogen or mixed gas of hydrogen and nitrogen, adopted in fat-contained food has the effect of extending the peroxide value index quality guarantee period more than twice and effectively prevents the rancidity of the fat-contained food and the reduction of colors.
Description
Technical field
The present invention relates to a kind of food storage technology, specifically is hydrogen charging food packaging technology.
Background technology
The food preservation packing technique, mainly pack in the mode of vacuumizing at present, such packing is for containing fatty foods, and the peroxide value problem that exceeds standard will appear in the general above time of half a year, the problem that pickle cured meat product particularly, vacuum packaging are difficult to avoid peroxide value to exceed standard and occur becoming sour.Cause product not eat after three months, bring greater loss to enterprise.The food quality safety problem appears.
Summary of the invention
Purpose of the present invention adopts a kind of hydrogen charging food packaging technology exactly, contains the big food of oil quantity and exists shelf time short and occur the problem that peroxide value increases gradually or exceeds standard in various degree at shelf time to solve present vacuum packaging.
Concrete technical scheme is as follows:
Hydrogen charging food packaging technology comprises food to be packaged and packaging bag and gas Flushing Machine, and key is to use gas Flushing Machine to charge into the mixture gas of hydrogen or hydrogen and nitrogen in evacuated packaging bag.Wherein charge into pure hydrogen packing, charge air is not less than 10% of packaged food volume, charges into hydrogen and nitrogen mixture packing, the volume ratio of two kinds of gases be hydrogen greater than 10%, all the other are nitrogen.
According to hydrogen charging food packaging technology, after packaging bag should being vacuumized usually, when packaged food, charge into pure hydrogen in to packaging bag, charge air is not less than 10% of packaged food volume.When the packaging bag of making vacuum was charged into the miscellaneous gas of hydrogen and nitrogen, the amount of the mixture gas that charges into was not less than 50% of packaged food volume.
According to hydrogen charging food packaging technology, be mainly used in the sealed package of fat-containing food.Charge into the hydrogen usage method: require to decide according to the amount of fatty (grease) and freshness, the length of maintenance phase.Generally according to the amount of fat (grease) with charge into amounts of hydrogen and be directly proportional, the freshness of packaged food with charge into amounts of hydrogen and be inversely proportional to (promptly fresh more food hydrogen usage is few more), the preservation time be directly proportional with hydrogen usage (be the preservation time is grown hydrogen usage big more).
The present invention's employing is filled hydrogen and is packed fatty food, produce peroxide with effective control fat, utilize hydrogen to stop hydroperoxides and free radical, prevent the chain transmission, assurance contain fatty foods not in a large number fast speed produce peroxide, prevented and treated becoming sour of food.Can not introduce the murder by poisoning composition by the food that fills the hydrogen packing, can farthest obtain keeping to wherein nutritional labeling, prevent and treat the peroxide value food spoilage that exceeds standard, become sour and cause of food storing process loss of nutritive components and control grease, the storage that improves food is worth.
The specific embodiment
Below provide embodiments of the invention:
Example 1, be used for the packing of ham food.Be divided into the block of the amount of determining or be cut into sheet after pickling ripe ham removal top layer, go into packaging bag, be evacuated earlier, then charge into the hydrogen that the ham volume is measured more than 2/3.The remaining volume of packaging bag is greater than 1 times of packing material, also can charge into the hydrogen that is not more than the packaging bag volume and the mixture gas of nitrogen, and in the mixture gas, hydrogen is no less than 2/3.This is because the peroxide of pickling in the ripe ham food has entered induction period, and belongs to the big food of lubricant component, so charge air is big, the hydrogen content in the mixture gas also should be big, could guarantee long period preservation requirement.Ham food seasoning after handling like this 3 months reduces below 50% with the vacuum-packed peroxide value of comparing, and the peroxide value in the shelf-life is starkly lower than control sample.Particularly under shelf life is subjected to photoenvironment, fills the hydrogen packing and compare, controlled to significant effective the generation of peroxide, prevented to become sour with control sample.Make the constant brown of ham lean meat, fat meat is non-yellowing.
Example 2, contain the grease cake food fill the hydrogen packing method, food to be packaged is placed packaging bag, be evacuated earlier, charge into the hydrogen of a many packaging bag volume 1/2 volumes again, or charging into the hydrogen that is not more than the packaging bag volume and the mixture gas of nitrogen, the hydrogen ratio in the mixture gas is no less than 1/3.The peroxide result of variations is identical with example 1.
The gas flush packaging of example 3, fried food, take and the identical method of above-mentioned second example, in packaging bag, charge into hydrogen or hydrogen nitrogen mixed gas, it is quite a few in 1/3 of the packaged volume of food of packaging bag to fill amounts of hydrogen, charge into the hydrogen nitrogen mixed gas of packaged volume of food more than 50%, wherein the content of hydrogen in mixture gas should be no less than 1/3.
The hydrogen that fills of example 4, bakery product is packed identical with example 2,3, fill amounts of hydrogen and be controlled at more than 2/5 of packaged volume of food in the packaging bag, the amount of filling hydrogen nitrogen mixed gas is controlled at more than 4/5 of packaged volume of food in the packaging bag, and wherein the content of hydrogen in mixture gas should be no less than 1/3.
Example 2,3,4 described later fill the hydrogen packing method, with compare, the peroxide value index shelf-life all prolongs more than one times, be subjected under the illumination irradiation environment, fill the hydrogen packing and compare with control sample, the generation of obvious and effective control peroxide has prevented to become sour, control peroxide value, color and luster keep good.
So, adopting the packing fill hydrogen or to fill hydrogen-nitrogen mixture gas to have a peroxide value index shelf-life to fat-containing food and prolong effect more than one times, actv. has prevented the variation of becoming sour of fat-containing food and color and luster.
