Other chemical treatments of fresh product may also affect flavor. Calcium treatment of fruit is a
widely used practice aimed mainly at avoiding the development of bitter pit. Calcium treatment of
commercially mature “Golden Reinders” apples notably enhanced the production of aroma volatile
compounds after mid-term storage under air and, to a lesser extent, under standard CA. Aroma volatile
production was severely depleted in ultra-low oxygen atmosphere stored samples, and calcium
treatment could not overcome this inhibition [117]. Methyl jasmonate (MJ) alone and in conjunction
with ethanol, is able to modify the biochemical pathways of volatile compounds [118]. Reports in the
literature have described the impact of MJ on biosynthesis of volatile compounds in both climacteric
fruit, such as apples and non-climateric fruit, such as strawberries [119–122]. The application of MJ
ay avoid undesirable alterations in the volatile fraction occurring postharvest and during storage, as
well as minimizing aroma losses. Postharvest MJ treatments in combination with ethanol on the
rmation of aroma constituents in berryfruit (raspberries, strawberries and blackberries) showed
different effects according to berry species. In contrast to raspberries, which exhibited a significant
decline in the total amount of volatiles after treatment, a significant enhancement of total volatile
compounds was observed in strawberries, while no significant effect was found in blackberries. Esters
and terpene compounds responded similarly in strawberries and blackberries suggesting similarity in
