Modified atmosphere packaging for baked products

The pace of work and life is also accelerating with the development of the economy. Baked foods are sought after by the younger generation and urban white-collar workers due to their portability and ready-to-eat nature, and are gradually replacing traditional meals. As a result, thermoformed modified atmosphere packaging baked products have also been developed.

At present, although most baked foods are made at high temperatures throughout the entire production process, they are very easy to mold in the later packaging and storage stages, resulting in the taste of the food being rancid, and the color and nutritional value being greatly reduced. Propionic acid and its salts are currently the main preservatives, but according to research results, all propionic acid (even if added in accordance with national standards) is related to migraines. Although many companies have also launched many preservatives and fresh-keeping agents, the main raw materials always contain propionic acid and its salts.

So in addition to using chemical preservatives and fresh-keeping agents, are there other ways to preserve food? The answer is yes. At present, the most advanced, safe, and scientific way to preserve food is modified atmosphere fresh-keeping packaging. The so-called modified atmosphere packaging MAP (Modified atmosphere packaging) or CAP (controlled atmosphere packaging) is also called replacement gas packaging or inflation packaging. Simply put, it is to extract oxygen and fill it with inert gases such as CO2 and N2 as needed to prevent the physical, chemical, biological and other aspects of food from deteriorating or slow down the rate of quality decline, thereby extending the shelf life of food.

Experiments have confirmed that under the same storage conditions, compared with traditional packaging, the shelf life of baked foods such as bread and sandwiches in modified atmosphere packaging can be extended by 3 times or more. At the same time, the packaging material uses high-barrier composite plastic film, which has better effect.

Shandong Inchoi Machinery, specializing in the production of fully automatic vacuum air conditioning fresh-keeping packaging, cooperates with many foreign baking companies, has rich technical experience, can help companies equip personalized packaging solutions, improve production efficiency, prevent secondary pollution, and reduce the transportation costs of manpower and materials. It is a trustworthy partner for the majority of baking companies.
