Modified Atmosphere Packaging MAP Equipment Xingyuan offers modified atmosphere packaging (MAP) equipment, also called nitrogen or gas flushing equipment, is an innovative technology that extends the shelf-life of food products without the need for preservatives or freezing. MAP is a unique technology that creates modified atmosphere that can achieve residual oxygen rates of 1% or less. Additionally, products packed with MAP cause no harm to texture or appearance in your products, opening entirely new markets. Prolonged shelf life will provide you with maximum efficiency in the supply chain, save in spoilage, and will significantly improve your profitability as a producer and supplier of food products. What is modified atmosphere packaging? According to the FDA, modified atmosphere packaging "involves either actively or passively controlling or modifying the atmosphere surrounding the product within a package made of various types and/or combinations of films." A modified atmosphere can be defined as one that is specially created by altering the natural distribution and makeup of atmospheric gases. When applied to packaging, this involves modifying or controlling the makeup of gases contained within each package to provide optimal conditions for increasing the shelf life and reducing oxidation and spoilage of perishable food and beverage products. There are two different kinds of modified atmosphere packaging: Passive and active.The Food and Drug Administration (FDA) define active modified atmosphere packaging as"the displacement of gases in the package, which is then replaced by a desired mixture of gases"and passive modified atmosphere packaging as"when the product is packaged using a selected film type, and the desired atmosphere develops naturally as a consequence of the products' respiration and the diffusion of gases through the film." What are some examples of modified atmosphere packaging? 1. Gas flushing For food and beverage products, nitrogen is most often used to decrease the amount of ambient oxygen within that package, as this gas can increase the rate of product spoilage. Nitrogen gas flush is a MAP option that many of our clients use. This can occur inside the package itself as well as in the steps leading up to packaging, like inside the filling apparatus. During this process, nitrogen gas is actively pumped in to displace oxygen. The FDA reports that this accomplishes three things: Displacement of oxygen to delay oxidation Decreasing the growth of aerobic spoilage organisms Acting as a filler to maintain package conformity 2. Barrier packaging films Choosing specific packaging films that provide increased protection is another example of modified atmosphere packaging. This is accomplished by using barrier packaging materials that provide decreased permeability to moisture and oxygen, such as low-density polyethylene (LDPE), polyvinylchloride (PVC) or polypropylene (PP), according to FDA.
