“…Even β-ionone is considered one of the most relevant compounds of red raspberries aroma (Larsen et al, 1991;Klesk et al, 2004). In this study, both compounds were detected as the most abundant, Kafkas et al (2019) reporting similar results with other raspberry varieties (´Tulameen´, ´Kweli´ and ´Imara´). Although these compounds were significantly affected by the fertilization system, presenting a higher percentage of abundance in conventional management, this difference was not consistence by crop cycles, since β-ionone was more abundant in the 2017 cycle and, α-ionone in the 2018 cycle (p ≤ 0.05).…”

“…These compounds are generated by the oxidative breakdown of carotenoids (Hampel et al, 2007) and have been reported as the most abundant group in other varieties (Aprea et al, 2010;Morales et al, 2014). Unlike other authors who detected ketones as the most abundant group (Kafkas et al, 2019). This functional group was significantly affected (p ≤ 0.05) by the fertilization system, presenting higher relative abundance percentages in conventionally fertilized raspberry, in both years of study.…”

Raspberries are widely consumed; the taste of the fruit is determined by the interaction between sugars, organic acids and a set of volatile compounds. Meanwhile, organic agriculture has developed rapidly as an alternative to conventional system and has been driven by the demand for pesticide-free food that brings greater benefits to human health. However, this system can alter the integral quality of the fruit, including the aroma, which has been little studied. Therefore, the objective of this study was to evaluate the effect of the application of organic and conventional fertilizers, in the presence of volatile compounds synthesized in the cv. ‘Heritage’ raspberry, during two crop cycles. The qualitative profile of volatile compounds was analysed by mass gas chromatography, obtaining as a result that fertilization treatments significantly affected the emission of volatile compounds in the most abundant functional group (C13 norisoprenoids) 48.5 vs. 25.8% and 56.9 vs. 29.1% in conventional and organic, in 2017 and 2018, respectively (p ≤ 0.05). The crop cycle affected the concentration of aldehydes (11.2 vs. 30.6% in organic, in 2017 and 2018, respectively (p ≤ 0.05). Impact compounds such as α-ionone (13.92 vs. 9.08% and 25.34 vs. 9.17% in conventional and organic in 2017 and 2018, respectively) and β-ionone (24.93 vs. 14.10% and 22.66 vs. 15.94% in conventional and organic in 2017 and 2018, respectively), presented greater abundance in conventional fertilization (p ≤ 0.05). Since there were changes in the volatile compounds, it is recommended to study whether the consumer perceives these changes.
