The aim of this study was to investigate the effects of ultraviolet-C (UV-C) irradiation on the changes in total sugars concentration and texture of ready to cook baby corn during cold storage. The baby corns were irradiated with UV-C at the dose of 0 (control), 2.2, 4.4 and 6.6 kJ m−2 and then stored at 5 ± 1 °C for 7 days. The results showed that the losses of total sugars were delayed by UV-C irradiation treatments. All the UV-C treatments significantly maintained the firmness of the treated baby corn samples and prevented the increase in electrolyte leakage, especially at 4.4 kJ m−2. Compared to control sample, the 4.4 kJ m−2 UV-C irradiated baby corn retarded the depolymerisation of pectin substances by suppressing the polygalacturonase and pectin methyl esterase activities. Therefore, the dose of 4.4 kJ m−2 could be a feasible alternative UV-C treatment maintaining texture and the total sugar concentration of ready to cook baby corn during commercial storage.

The effects of UV-C illumination at the dosage of 6.6 kJ m-2 on postharvest quality of mango fruit cv. ‘Kaew Kamin’ during storage at 25 or 12°C were investigated. The changes in fresh weight, texture, Ripening Index (RI), peel and pulp colours, visual appearance, Total Carotenoids (TC) and Ascorbic Acid (AsA) content were determined on days 0, 4, 8, 12 and 16 of storage. UV-C irradiation effectively maintained the fruit firmness and delayed the increase in RI and the loss of peel greenness over storage. No treatment had any effects on pulp yellowness over storage. The incorporation of UV-C illumination and refrigerated storage (12°C) prevented postharvest disease and maintained nutritional values such as TC and AsA content. In conclusion, UV-C irradiation appears an effective alternative approach to maintain postharvest quality and nutritional values and to extend shelf-life of ‘Kaew Kamin’ mango fruit.

Due to the high cost of mechanical refrigeration, Evaporative Cooling (EC) can be an alternative technology for small farmers in developing countries, such as Thailand. This study aimed to experimentally investigate the performance of EC using a wet fabric blanket. A real-scale cargo chamber, commonly used in Thailand, was constructed, and equipped with axial fans to simulate airflow during transportation. Two pallets of test products (hollow plastic balls) were loaded into the cargo and covered with the wet blanket. During the experiment, the inlet air velocities varied from 0.8 m s−1 to 3.6 m s−1 while the constant climate conditions were maintained (29–30 °C and 70–73 %RH). The air and product temperatures and air relative humidity were measured every minute for 3 h using thermocouples and hygrometers, respectively. The proposed EC method allowed the air temperature to decrease by approximately 3–4 °C. When the inlet air velocity decreased, a lower temperature reduction was observed. Simplified heat and mass transfer models were developed to interpret the load temperature evolution from the inlet to the outlet positions at different air velocities. The comparison between the measured and calculated data revealed a maximum mean relative error of 1.2 %. The quality preservation performance was also evaluated based on lettuce mass loss. Lower mass loss was observed for the product stored inside the cargo chamber (<6 %) compared to those outside (8–10 %). This study suggests the potential use of a wet blanket as an EC cooling medium for a short-distance transport to enhance the cold chain performance in Thailand.

The effects of honey solutions on preventing browning discoloration and maintaining visual appearance in fresh-cut 'Nam Dok Mai' mango fruit and the comparison of honey dip and commercially used citric acid and ascorbic acid dips were investigated. The mango cubes were dipped in honey solutions at the concentration of 0, 5, 10, 15, 20 or 25 % (v/v) and the visual appearance and browning intensity (ΔOD<inf>420</inf>/100g FW) were determined after storage for 24 h. The cubes dipped in 25 % honey solution showed the lowest browning intensity and the best visual appearance compared to the others. The 25% honey dip and 1% citric acid dip inhibited the browning of the mango cubes stored at 4°C for 6 days more than 1% ascorbic acid dip and the control. All treatments had no effect on the changes in weight loss, yellowness (b* value), hue angle and chroma over storage. The honey dip showed higher overall acceptance score and L* value and lower colour difference (ΔE*) than the others. In conclusion, 25% honey dip showed a potential maintaining visual appearance and inhibiting browning discoloration in fresh-cut 'Nam Dok Mai' mango fruit during storage.

The quality of minimally processed apples is influenced by enzyme-induced browning and physicochemical changes during storage. Cysteine is identified as a promising natural compound that can inhibit enzymatic browning reactions in foods. This research aimed to enhance the efficacy of cysteine through liposome encapsulation to impede enzymatic browning, improve oxidation resistance, and sustain the quality of fresh-cut ‘Fuji’ apples during refrigeration for 10 days. The samples were subjected to treatment with liposome-encapsulated cysteine (0.1%) (LEC), cysteine (0.1%), and ascorbic acid (0.1%). The particle size and zeta potential values of LEC were 208.10 nm and − 62.30 mV. Compared to the control, all treatments preserved the firmness and whiteness and inhibited all investigated parameters related to browning incidence, oxidative responses, bioactive compounds, and antioxidants. The LEC treatment demonstrated a significantly higher ability to preserve flesh whiteness, reduce brown occurrence, inhibit the activity of browning-related enzymes (peroxidase and polyphenol oxidase), limit increases in hydrogen peroxide and malondialdehyde levels, and maintain elevated levels of both reducing antioxidant potential and free radical scavenging activity, compared to treatments with cysteine or ascorbic acid alone (p < 0.05). Furthermore, it adequately preserved firmness (> 30 N) and minimized weight loss (< 2%) throughout storage. The amounts of bacteria, yeast, and molds stayed low and were unaffected by any of the treatments applied. In summary, the encapsulation of liposomes significantly improved the efficacy of cysteine in preventing enzymatic browning, promoting oxidative resistance, and enhancing the physicochemical quality of fresh-cut apples compared to the use of cysteine alone.

The effect of calcium propionate (Ca-propionate) on physicochemical quality changes of ready cook baby corn (Zea mays L.) during storage was investigated. It was found that Ca-propionate treatment retarded the loss of texture which was concomitant with the lower EDTA-soluble pectin and higher Na<inf>2</inf>CO<inf>3</inf> soluble pectin concentrations compared to untreated baby corns. Ca-propionate treatment did not obviously affect total sugars content, antioxidant activity and free radical scavenging activity compared to untreated samples. However, Ca-propionate treatment induced bioactive compounds such as total phenols, flavonoids and ascorbic acid contents of ready cook baby corns during storage. Therefore, Ca-propionate immersion is an alternative improving quality especially texture and nutritional values of ready cook baby corns during cold storage.

The rapid acceleration of ripening during ambient storage is a primary factor limiting the shelf-life of bananas. Application of methyl jasmonate (MeJA) has been used to enhance the postharvest quality of perishable commodities. This study aimed to investigate the efficacy of MeJA (10−3 M) encapsulated in liposomes (MeJA-liposomes) on the postharvest quality of ‘Kluai Khai’ bananas (Musa AA) during storage at room temperature (26 ± 2 °C) for 9 d The MeJA-liposomes exhibited an average particle size of 152.37 ± 1.63 nm with a PDI of 0.21 and a zeta potential value of -33.9 ± 1.02 mV. The MeJA-liposomes treatment exhibited a greater delay in fruit ripening and peel colour development compared to the MeJA (10−3 M), blank-liposomes, and control treatments, respectively. MeJA-liposomes reduced the oxidative stress of the peel by decreasing electrolyte leakage, lipoxygenase activity, and the levels of malondialdehyde, α-fanesene, conjugated triene (CT-281) and H<inf>2</inf>O<inf>2</inf> in the fruit peel. As the ripening process in untreated bananas progressed, they exhibited greater antioxidant activities, namely in terms of ferric reduction antioxidant capacity and DPPH radical scavenging activity in the peel, compared to the MeJA-liposome-treated bananas. The application of MeJA-liposomes treatment resulted in a postponement in the process of softening and an increase in the levels of total soluble solids content, and BrimA in the banana pulp throughout the storage period. In conclusion, the application of MeJA-liposomes presents a promising method for postponing the ripening process, alleviating the oxidative response in the peel and prolonging the shelf-life of ‘Kluai Khai’ bananas (Musa AA) at room temperature.

The physicochemical and antioxidant changes of ‘Kluai Leb Mue Nang’ banana fruit (Musa AA group) were investigated during ripening. The visual appearance, peel and pulp color, firmness, total soluble solids concentration (TSS), total acidity (TA) and bioactive compounds of the fruit at three stages of ripening (mature green, ripe and overripe) were monitored. Changes in both the peel and pulp color, texture, TSS and TA contents during banana ripening were similar to those of other banana fruits. Interestingly, the highest total antioxidants capacity and total phenols concentration were found in the ripe banana fruit. 2,2-Diphenyl-1-picrylhydrazyl radical scavenging activity remained constant and the highest total flavonoids concentration was found in the mature green fruit.

The effect of natural coating by using fresh Aloe vera (A. vera) gel alleviating browning of fresh-cut wax apple fruits cv. Taaptimjaan was investigated. The fresh-cut fruits were dipped in fresh A. vera gel at various concentrations of 0, 25, 75 or 100 % (v/v) for 2 min at 4 ± 1 °C for 6 days. Lightness (L*), whiteness index (WI), browning index (BI), total color difference (ΔE*), sensorial quality attributes, total phenolic (TP) content, antioxidant activity and polyphenol oxidase (PPO) and peroxidase (POD) activities were determined. During storage, L* and WI of the fresh-cut fruits surface decreased whilst their BI and ΔE* increased. A. vera coating maintained the L* and WI and delayed the increase in BI and ΔE*, especially at 75 % A. vera dip. The fresh-cut fruits dipped in 75 % A. vera had the lowest browning score, the highest acceptance score and delayed the increase in TP content and PPO activity. However POD activity was induced by A. vera coating. Antioxidant activity had no effect on browning incidence of the fresh-cut fruits. Consequently, A. vera gel coating could maintain quality and retarded browning of fresh-cut wax apple fruits during storage.

The effects of ultrasound (US) power of 200 w at a constant frequency of 40 kHz for 2 min, 0.01 % cysteine (Cys) and combinative application of US and Cys (US + Cys) on browning prevention and quality of lotus root slices were compared during storage at 4 °C for 12 d. The visual appearance, colour attributes including L*, b*, hue, chroma, whiteness index (WI), browning index (BI) and colour difference (ΔE*), browning enzymes activities such as polyphenol oxidase (PPO) and peroxidase (POD), total phenols concentration, texture, total sugars concentration and antioxidant activities were evaluated. US + Cys retarded browning incidence being greater than Cys, US and control treatments, respectively. The browning retardation was concomitant with the retention of high L* and WI values and low b*, chroma, BI and ΔE* value. Cys and US + Cys controlled the increased PPO activity rather than US. All treatments delayed the increased total phenols concentration compared to control. All treatments maintained hardness of lotus root slices, especially US, and did not affect total sugars concentration. Both sonication treatment enhanced ferric reducing antioxidant potential (FRAP) whilst free radical scavenging activity was enhanced by Cys. In conclusion, both of the Cys and US could prevent browning and maintain physicochemical quality of lotus root slices and the simultaneous US and Cys treatment exhibited synergistic antibrowning effect.
