“…More specifically, there was a positive correlation between them, as shown by a sudden increase in ethylene concentration preceding a sudden rise in CO 2 production [4]. These changes in both gases contributed to an increase in the respiration rate, which led to an autocatalytic effect that accelerated the maturation of the product [7,12,22].…”

“…For this, 20 g of fresh peach were weighed and brought to a volume of 100 mL with deionized water; the resulting mixture was titrated to a pH of 8.1 ± 0.1 with NaOH 0.1 N and constant stirring. The percentage of acid in the sample was calculated and expressed as a percentage according to [4].…”

“…Apart from the crucial control of the optimal storage temperature, ethylene concentration is one of the most important parameters during post-harvest conservation of climacteric fruit. Ethylene (C 2 H 4 ) is a phytohormone that, even in low concentrations, can produce undesirable changes in physical and chemical parameters in fruits, such as changes in firmness, colour, pH, or maturity index [4][5][6][7]. Therefore, limiting its presence has proven to be an economically and commercially key process for avoiding post-harvest losses and food wastage.…”

The aim of this study was to evaluate the combination of two ethylene removal methods and temperature on the post-harvest quality of peaches. For this purpose, filters with potassium permanganate (KMnO4) and lamps emitting ultraviolet light (UV) were mounted on machines which enabled air movement in the conservation chambers, facilitating the removal of ethylene by KMnO4 and photocatalysis simultaneously. This system was used at two temperatures, 1 °C and 25 °C, simulating an ideal storage temperature in industry and extreme temperature to observe faster ripening, respectively. The results obtained showed that this combination of ethylene scavengers favoured the efficient elimination of this gas. Consequently, the use of this innovative technique made possible a better preservation of fruit firmness, colour, soluble solids content, pH, total acidity, and maturity index. Moreover, using this method in peaches subjected to 25 °C increased their survival by seven days more than those without this system, indicating the effectiveness of ethylene scavengers even under these extreme temperatures.

“…The ethylene and CO 2 production from flat peach samples was determined following the procedure described previously [ 25 ]. Briefly, glass jars containing the samples (4 fruit samples) were closed with the hermetic lids (which already contained a sampling port for gas analysis) and ethylene and CO 2 were allowed to accumulate for 2 and 1 h, respectively.…”

Plant essential oils (EOs) have several bioactive properties, highlighting their high antimicrobial and antioxidant capacities. As such, the use of EOs in active packaging has received special attention in the last few years. Nevertheless, the inhibitory effect of EOs on quality-degrading enzymatic systems of plant products during postharvest life has not been deeply studied. The effects of an EO active paper sheet on ethylene biosynthesis and quality (and related quality-degrading enzymes) of flat peach (Prunus persica var. platycarpa) samples were studied during 5 days (continental terrestrial transport) or 26 days (long maritime transport) storage at 2 or 8 °C, both followed by commercialization simulations (4 days at 22 °C). EOs released from active packaging reduced ethylene production by 40–50%, and by up to 70% after commercialization periods. These results were correlated with lower 1-aminocyclopropanecarboxylic acid (ACC) content and ACC-oxidase activity. Physicochemical fruit quality (as indicated by soluble solids content, titratable acidity, color, and firmness) was also better preserved by EO active sheets due to enzymatic inhibition (polygalacturonase and polyphenoloxidase). Furthermore, phenolic compounds (mainly catechin and cyanidin-3 glucoside) and total antioxidant capacity were increased (by up to 30 and 70%, respectively) in EO-packaged samples after 8 °C storage and the subsequent commercialization period. Conclusively, EO active paper sheets controlled ethylene production in flat peaches, maintained fruit quality, and even increased health-promoting bioactive compounds.
