“…The production of these compounds occurs naturally under normoxic oxygen conditions, in proportion of one part of acetaldehyde to 100 parts of ethanol (PODD; VAN STADEN, 1998;ZABALZA et al, 2009); however, when stored under hypoxic conditions, there is an increase in the synthesis of both. Compounds from fermentation have great influence on several metabolic routes, ethylene synthesis, aroma production, respiratory metabolism, and expression of some enzymes and proteins, thus acting on the post-harvest quality of fruits, vegetables and flowers (PODD; VAN STADEN, 1998, PESIS, 2005, ASODA et al, 2009, MORI et al, 2009, BOTONDI et al, 2012LIU et al, 2012). However, when present in the fruit in large amounts, they may increase the occurrence of physiological disorders.…”

“…Fruits exposed to 20 μL L -1 nitric oxide and ethanol produced more ethyl acetate than the other treatments, probably because these compounds stimulate the activity of the alcohol acetyltransferase enzyme (AAT). According to Liu et al (2012), ethyl acetate is produced through the action of the alcohol acetyltransferase enzyme (AAT), which converts ethanol into ethyl acetate and other esters responsible for fruit aroma.…”

-The aim of this work was to evaluate the effect of ethanol and two nitric oxide dose applications on the maintenance of the post-storage quality of 'Galaxy' apple during storage under controlled atmosphere (CA) nitric oxide showed lower ethylene production, respiration rate and ACC oxidase ( (1-aminocyclopropane-1-carboxylic acid) oxidase enzyme activity. Apples treated with 20 uL L -1 nitric oxide showed higher ethylene production, respiration rate, internal ethylene concentration CO 2 and ethanol concentration. Ethanol and nitric oxide application before storage have no benefits in maintaining fruit quality after storage under CA due to lower flesh firmness, higher mealiness incidence, flesh breakdown and decay incidence. Index terms: Ethylene, respiration rate, fermentation compounds, Malus domestica. Os frutos foram mantidos em AC durante oito meses e sete dias a 20º C. Frutos tratados com etanol apresentaram maior produção de etileno, menor firmeza, elevada degenerescência, polpa farinácea e produção de acetaldeído. Já, os frutos tratados com 40 µL L -1 de óxido nítrico apresentaram menor produção de etileno, taxa respiratória e atividade da enzima ACC (1-aminociclopropano-1-carboxílico) oxidase. Maçãs tradadas com 20 µL L -1 de óxido nítrico apresentaram aumento na produção de etileno e respiração, etileno e CO 2 interno, e produzem mais etanol. A aplicação de etanol e óxido nítrico não apresenta benefícios na manutenção da qualidade dos frutos após o armazenamento em AC, devido à menor firmeza de polpa, maior ocorrência de polpa farinácea, degenerescência de polpa e incidência de podridões nos frutos. Termos para indexação: Etileno, taxa respiratória, compostos da fermentação, Malus domestica. ETANOL E ÓXIDO NÍTRICO NA MANUTENÇÃO DA QUALIDADE DE MAÇÃS 'GALAXY' ARMAZENADAS EM

“…The ethylene levels under 1 kPa O 2 + 3 kPa CO 2 and 0.5 kPa O 2 + 6.0 kPa CO 2 were substantially reduced. Low O 2 conditions reduce oxidative metabolism and enhance fermentation (Imahori et al 2013) and ripening may also be delayed by ethanol (Asoda et al 2009), especially by decreasing ACC-oxidase activity and ethylene production (Liu et al 2012). Thewes et al (2015) also observed lower ACC-oxidase activity in 'Royal Gala' apples when stored under O 2 partial pressures lower than 0.6 kPa.…”

“…The reduced oxygen level in the storage room reduces oxidative metabolism by enhancing fermentative pathways, which induces ethanol production (Imahori et al, 2013). Therefore, ripening may be delayed by the induced production of ethanol metabolites or ethanol application (Asoda et al, 2009), especially by decreasing ACC oxidase activity and ethylene production (Liu et al, 2012). Brackmann et al (2013) also observed lower ACC oxidase activity in 'Royal Gala' apples when stored under low oxygen partial pressure (0.6 kPa).…”

Apples (Malus domestica, Borkh.) which are not stored at low temperature or in a properly controlled atmosphere (CA) may have a high metabolic rate during the postharvest stage resulting in losses in quality. The aim of this study was to evaluate the quality of 'Royal Gala' apple fruit stored in accordance with a new method of dynamic controlled atmosphere (DCA).The respiratory quotient (RQ) was monitored at two temperatures which were then compared using a commercially available technology based on chlorophyll fluorescence DCA (DCA-CF) and static CA. Ethylene production and respiration rates were lower in apples stored in DCA than in CA, as a result of lower 1-aminocyclopropane-1-carboxylate oxidase activity, especially in apples stored in DCA-RQ2. Flesh firmness of apples stored in DCA did not differ from those stored in CA. Apples stored at 1 °C had less flesh breakdown occurrence and a high percentage of healthy fruit. 'Royal Gala' stored at DCA-RQ2 had less flesh breakdown than apples stored in CA; however, the apples stored in DCA-CF did not differ from those stored in DCA-RQ2 and CA. Apples stored at the highest RQ value (6 and 4), especially at 0.5 °C, had low O 2 injury occurrence after storage. However the increase in temperature to 1.0 °C, reduced the occurrence of this disorder. Therefore, storage in DCA-RQ2 at 1 °C or DCA-CF at 0.5 °C are the recommendations of preference for ensuring maintenance of quality in 'Royal Gala' apples after eight months of storage.
