A Study on Extending the Shelf Life of Guavas Using Proper Packaging-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 A Study on Extending the Shelf Life of Guavas Using Proper Packaging Fruits like guava lose freshness due to moisture loss and oxygen exposure. Similar issues affect many other products that are sensitive to light, temperature, and air. Various methods are used to maintain product shelf life, including lowering temperature, increasing humidity, reducing air movement, and using special packaging materials. These materials can be high-barrier films, coatings, or have specific thicknesses.

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 C640 Thickness Tester is a high precision mechanical contact method thickness tester, which can be used for thickness measurement of films, sheeting, paper, corrugated paperboard, textiles, non-woven fabrics, and solid insulation materials, etc. Auto sampler is optional, which is designed for multiple successive points thickness measurement. This research studied three types of commonly available packaging films for guavas stored at two temperatures (5°C and 10°C). The films were:    Low-density polyethylene (LDPE) in two thicknesses...

A Study on Extending the Shelf Life of Guavas Using Proper Packaging-4

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 The research found that PVC films came closest to offering the desired OTR and CTR for guavas. However, none of the studied films allowed enough water vapor transmission (WVTR) for optimal guava storage. PVC 40 film provided the longest shelf life (25 days at 5°C and 20 days at 10°C). Guavas stored in this film retained brighter color, became softer (considered mature), and were well-received by testers. The high WVTR of PVC 40 film might require a moisture absorber inside the package to prevent condensation. In conclusion, the...
