Vacuum
packaging machine by air or air way for packaging for some of our products, and it can be packaged goods all-encompassing, many issues we need to be careful when food packaging, because food is easy to corrosion become rotten, affecting taste, different foods have different considerations, today we mainly to know about the packing tea when should pay attention to matters of content.
1, gas the fragrance of the tea is easily lost, and easily affected by the peculiar smell, especially composite membrane residual solvents and electric iron processing, heat sealing processing into the smell will affect the tea flavor, making the aroma of tea.
Tea packaging machine packaging tea, therefore, should avoid the dissipation from the packaging of fragrance and absorb peculiar smell from the outside world.
Tea packaging materials need to have a certain block gas performance.
2, anti high temperature
temperature are important factors that result in the change of tea quality, temperature is 10 ℃, the rate of chemical reaction is 3 ~ 5 times.
Tea exacerbate containing substances oxidation at high temperatures, leading to effective material such as polyphenols decrease quickly, the speed up of quality deterioration.
Tea storage temperature below 5 ℃.
10 ~ 15 ℃, tea color fade slowly.
Colour and lustre effect can maintain is good, when the temperature more than 25 ℃, the tea color will change quickly.
Therefore, the tea is suitable for preserved in low temperature.
3, moistureproof
vacuum packer can complete vacuum packing work on the efficiency of the tea, water is the medium of tea biochemical changes, low moisture content is conducive to the preservation of the tea quality.
Long-term preservation of moisture content of tea should not be more than 5%, to 3% when appropriate, otherwise the ascorbic acid in tea break down, such as color, aroma and taste of the tea will change, especially at higher temperatures, metamorphic can accelerate the speed of.
Tea packaging machine in the packaging, can choose moisture-proof performance good, such as aluminum foil or aluminum foil composite film materials on the basis of the evaporated film moisture-proof packaging for packing material.
4, anti-oxidation,
tea oxygen content in the vacuum
packing machine got flu treatment can lead to the oxidation of some components in tea.
Such as ascorbic acid easily oxidized into DNA ascorbic acid.
And pigment reaction with amino acids, the further worsen the tea flavor.
So.
Oxygen content in tea packaging to effectively control under 1%.
On the tea packaging machine packaging technology.
Inflatable packaging or packing method can be used to reduce the presence of oxygen.
Vacuum packing technology is put the tea into the tightness good soft film bags inside.
Out of the air bag when packing, caused a certain degree of vacuum, then seal sealing packing method;
Inflatable packaging technology is at the same time of exhaust air into the inert gas such as nitrogen, the purpose is to protect the tea color, aroma, taste stable, keeping its original quality.
5, shading light can promote chlorophyll in tea and oxidation of lipid, etc, make the tea valeraldehyde, propionaldehyde odor material such as increase, accelerate the aging of tea, so tea
packing machine in the packaging of tea, shall shading to prevent other ingredients such as chlorophyll, lipid photocatalytic reaction.
In addition, the ultraviolet ray also is the important factor causing the tea metamorphic.
Solve the problem can use sunscreen packaging technology.
the above is our vacuum packing machine in the matters needing attention when packing the tea, hope to help you.
For we finish packing the products if there is a bulge or leakage phenomenon is our packaging technology is unqualified, then will handle in time, otherwise affect the taste of the tea, also affect the quality of the tea.
