Master's thesis of Science: Application of olive leaf extract and chitosan as natural preservatives for beef patties

This study proceeded to address the following objectives: To evaluate the effect of gas composition commonly used in modified atmosphere packaging (80% O2 and 20% CO2) on the shelf life of beef patties; to formulate an optimal solution containing natural antioxidant and antimicrobial preservatives and to study the effect of this combination and MAP on physiochemical attributes (surface colour (chroma, hue angle), metmyoglobin and oxmyoglobin contents, lipid stability) of fresh beef patties; to evaluate the effect of combined antioxidant – antimicrobial natural preservative and MAP on packag...

Modified atmosphere packaging reduces pericarp browning and maintains the quality of ‘Huong Chi’ longan fruit (Dimocarpus Longan) pretreated with citric acid

The modified atmospheres generated by LifeSpan L201 and LDPE delayed pericarp browning, maintained the total soluble solids (TSS) and vitamin C content, and reduced decay in longan fruit. Meanwhile, the PP packaging resulted in an improperly modified atmosphere which led to severe decay and browning in cold storage conditions.
