The application of molecular sieves in the field of fruit preservation
The application of molecular sieves in the field of fruit preservation is multifaceted. due to their environmentally friendly and safe characteristics, have become an important choice in modern fruit preservation technology.
Molecular sieves play a pivotal role in the field of fruit preservation by controlling the composition of gases surrounding the fruit to extend its shelf life. Here are several ways molecular sieves are applied in fruit preservation:
Gas Adsorption: Molecular sieves can adsorb ripening gases like ethylene released by fruits, slowing down the ripening process and prolonging the preservation period.
Slow-Release Preservative Carriers: Molecular sieves act as carriers for slow-release preservatives, maintaining fruit freshness by gradually releasing the preservatives.
Nano-Packaging Materials: Molecular sieves combined with nanotechnology are used to develop new types of nano-packaging materials that provide an appropriate gas exchange environment to keep fruits fresh and nutritious.
Coating Preservation Materials: Molecular sieves are compounded with other natural polymers to form coating preservation materials that can act as a protective layer for fruits, isolating them from microbes and pollutants, and regulating their respiratory intensity.
Preservation Packaging Films: Molecular sieves are added to plastics like polyethylene to create preservation packaging films that regulate the internal gas composition, inhibit the growth of pathogens, and reduce fruit decay.
Gas Composition Control: In some smart packaging systems, molecular sieves are used to control the ratios of oxygen and carbon dioxide, creating a suitable storage environment for fruits.
Antimicrobial Preservation: Molecular sieves can carry antimicrobial substances, such as nano-silver, to inhibit or kill microbes on the surface of fruits, extending their shelf life.
The application of molecular sieves in the field of fruit preservation is multifaceted. They not only effectively extend the preservation period of fruits but also, due to their environmentally friendly and safe characteristics, have become an important choice in modern fruit preservation technology. With the advancement of technology and increasing demands for food safety, the application of molecular sieves in fruit preservation will become more widespread.
