Fruits and vegetables are still alive after they are picked, so they will continue to metabolize and respirate. Produce bag is designed to absorb the aging hormones that fruits and vegetables emit to cause self-ripening. This slows down the ripening process. Combined with the anti-bacterial and anti-mildew technology, the probability of bacteria growth is greatly decreased preventing the loss of fresh nutrients.
Oxygen Bag -utilizes the principle of "anti-oxidation" to achieve the effect of food preservation. The most important thing in food preservation is to inhibit the breeding of bacteria and microorganisms. Besides food nutrition; moisture, temperature, and oxygen are the three factors that microorganisms rely on to survive. Refrigerating food can slow down the growth of bacteria and microorganisms, but plastic bags used for normal packaging purposes cannot prevent oxygen and moisture from entering the bag because of the permeability of the material. Therefore, even in a low temperature environment, bacteria will proliferate due to the entry of oxygen, accelerating the rate of food spoilage.
Other features of Oxygen bag are:
(1) Low oxygen permeability locked the aroma of food completely inside the bag, preventing food flavour from being lost.
(2)The high tech low oxygen permeability material has an oxygen transmission rate of 500X lower than other PE plastic bags on the market.
(3) Cookies, nuts and other dry foods lose their crispy texture due to humidity in the air. Since Oxygen Bag segregates moisture in the air from entering the bag, foods stored inside will maintain their original texture.
(4) USii Oxygen Bag has 2x the penetration resistance compared to other Plastic bags on the market. Using our product there is no longer the worry of bags being damaged from sharp edges such as crab legs, or fish fins.
Should food stored in Oxygen Bag be refrigerated?
7~60â is known as the âdanger zoneâ as this temperature range is when growth of bacteria is highly active. In general, food must be heated over 70â to kill bacteria. High temperature storage should be higher than 60â while low temperature storage should be under 7â to inhibit the growth of bacteria. In order to prevent bacteria from breeding on food, it is recommended that generally food is not left under room temperature for more than 2 hours and during summer, when room temperature may reach above 32â, food can not left over 1 hour (From Taiwan Food and Drug Administration official website). Therefore, it is best that food is stored in a refrigerator for best preservation result.
How to properly use Oxygen Bag?
This bag is used as a storage device with high oxygen barrier. Therefore, it is recommended that consumers use the bag-in-bag method, which is more hygienic and easy to reuse and clean. The detailed explanation of the bag in bag is as follows:
A-1. After opening packaged food, keep the original packaging of the food, and put it Oxygen Bag.
A-2. Divide food into smaller portions with plastic bags, and then place several small portions into one Oxygen Bag.
A-3. It is safe to directly store food in Oxygen Bag, just make sure to clean after use, and fully dry before proceeding to the next use.
After storing food inside the bag please squeeze out the air inside as much as possible. Securely seal the zipper.
Can Oxygen Bag be used to store nuts and cookies? Should they be stored in a refrigerator?
Yï»żes they can! Nuts and cookies are prone to lose flavour and texture due to moisture and oxidation. Low temperature and low oxygen environments inhibit growth of microorganisms, therefore storing nuts and cookies in refrigerator are ideal. Storage at room temperature for long periods can be achieved with Oxygen bag, but the following principles are recommended to help achieve maximum preservation time:
1) Makes sure to squeeze excess air out of the bag and seal the zipper.
2) Store in a dry, ventilated environment away from sunlight, temperature should not exceed 25 â.
3) Please pour or use a clean spoon to take out the desired amount of food. Avoid hand contact.
4) Take out a single desired portion at a time to avoid the change of flavour upon exposure to moisture.
5) Finish food before an overly extended amount of time past the ideal shelf life of food.
Can Oxygen Bag be used to store fish?
Yes, Usii Oxygen Bag is the first domestic functional bag product designed for the preservation of food. Product is designed with the goal of minimizing oxygen transmission through bag film to slow down the oxidation and decay of food. For the preservation of fruits and vegetables please use Usii Produce Bag.
Can Oxygen Bag be stored in Freezer?
Usii Oxygen Bag can withstand temperatures from -20 to 70â, Cold temperatures around 0â is acceptable.
Temperatures lower than 0â may cause rupture of bag because of thermal expansion and contraction and food with sharp edges that may press against the bag material. If stored in the freezer, please gently place the bag at room temperature for 3-5 minutes before handling food in bag.
Why is the effect of the Oxygen Bag not the same every time?
Different foods have varying properties, therefore it will be slight differences in preserving effect. Foods also vary in freshness at the point of purchase. Even if placed in an Oxygen Bag, the preservation time of food will still be less than foods that are fresher.
Will the Bag Zipper age over time?
The force exerted on the zipper, weight of the food stored, storage environment and even atmospheric pressure, all have an effect on the lifespan of the bag's zipper. Therefore it is advised that the zipper is fully sealed everytime and the bag should placed upright.
Can Oxygen Bag be reused? How should it be washed before reuse? Does it need to be dried?
With environmental responsibility in mind, Oxygen Bag was designed to be reusable. In general, the bag can just be rinsed with clean water, however, if protein or oily foods were stored, it is recommended that the bag is washed using a sponge with dishwasher soap. The bag should be fully dried as water is a medium for microorganism breeding. It is advised that a bag should be thrown out after a month of use for hygienic reasons.
Under what conditions should Usii Oxygen Bag be thrown out before a month of use?
If there is damage to the bag during use, or the bag is contaminated with a substance that cannot be washed off, or food stored inside becomes seriously decayed, it is recommended to switch to a brand new bag.
