Impacts of Thermal Processing, High Pressure, and CO2-Assisted High Pressure on Quality Characteristics and Shelf Life of Durian Fruit Puree

Abstract

Durian fruit puree (DFP) is a nutrient-dense food, but it has a short shelf life. Presently, little research has been undertaken on extending the shelf life of DFP. Hence, it is necessary to develop treatment methods that can prolong the shelf life of DFP. In the present study, thermal processing (TP), high-pressure processing (HPP), and CO2-assisted HPP (CO2 + HPP) treatments are used for DFP, and their influences on quality properties of DFP during storage (35 days, 4 °C) are investigated. Compared to other treatments, the CO2 + HPP treatment had a lower pressure and a shorter time to achieve the same effect of inactivating the microorganisms of DFP. During storage, CO2 + HPP treated DFP showed higher retention rates of sugars, total soluble solids, color, bioactive components, and antioxidant capacity in comparison with other treated DFPs. Moreover, after 35 days of storage, the microbial count of (CO2 + HPP)-treated DFP (3.80 × 103 CFU/g) was much lower than those of TP (4.77 × 105 CFU/g) and HPP (8.53 × 103 CFU/g)-treated DFPs. The results of this study reveal that CO2 + HPP treatment could not only better preserve the quality of DFP, but also effectively extend the shelf life of DFP, providing an effective method for the processing of DFP.

Effects of Pulsed Electric Field and High-Pressure Processing Treatments on the Juice Yield and Quality of Sea Buckthorn

“…Total flavonoids in sea buckthorn juice were severely lost to 129.8 mg/100 g after TP treatment (180.03 mg/100 g in CK). A similar phenomenon was found in total flavonoid concentrations of durian puree after TP and HPP processing; TP retained only 80% of the flavonoids [40]. The decrease in content was attributed to structural damage, with high temperatures causing the degradation of flavonoids [41].…”

Changes and correlation analysis of volatile flavor compounds, amino acids, and soluble sugars in durian during different drying processes

“…It is primarily cultivated in Southeast Asian countries ( Ho, & Bhat, 2015 ). Durian is typically consumed fresh due to the challenges associated with transportation and storage ( Bu et al, 2022 , Niponsak et al, 2015 ). However, fresh durian has a pungent odor that necessitates processing to remove the unpleasant flavor while retaining its elegant aroma ( Xu et al, 2022 , Zhang et al, 2020 , Raihana et al, 2015 , Belgis et al, 2017 ).…”
