“…The mean value of total phenolics decreased by 41% in vacuum packed pawpaw pulp over 8 months of frozen storage and by 57% while stored for 8 months in the presence of air. The phenolic concentrations of pawpaw from this study are comparable to other fruits in the Annonacea family, including the soursop/guanabana/graviola, sugar apple, and cherimoya which ranged from 4-8 μmol gallic acid equivalents/g pulp (Almeida, et al, 2011;Barreca, et al, 2011). The main effects of time of frozen storage (three levels: 0, 4, 8 months) and treatment (four levels: vacuum, air, ascorbic acid, NAC) on total flavonoids were analyzed.…”

Polyphenol oxidase (PPO) activity values for pawpaw pulp during frozen storage were measured for the main effect of month of storage at three levels (0, 4, 8 months) and treatment at four levels (vacuum, air, ascorbic acid or n-acetylcysteine). A significant effect of treatment was observed in PPO activity (p<0.001). Post hoc analysis revealed no significant difference between samples that were vacuum packaged and those for which no attempt to exclude air was made. The addition of the two chemical browning inhibitors significantly lowered PPO activity. Ascorbic acid exhibited a significant 69% reduction in PPO activity compared to vacuum and air samples and n-acetylcysteine was significantly more effective than ascorbic acid and almost completely inhibited PPO activity compared to the vacuum and air samples. CIELAB tristimulous color values (L*, a*, b*) were used to generate the applied color values total color difference (E), browning index, hue and chroma in pawpaw pulp for the two main effects. Analysis of variance for the main effects showed significance for all seven color attributes at p<0.001. For the main effect of storage time, ANOVA showed significance during storage for all seven color attributes at p<0.001, indicating that there were color changes during storage. Pawpaw pulp samples at 8 months of storage were significantly darker (lower L*), more yellow (higher b*), more vivid (higher chroma), and had a higher browning index than the samples at 0 or 4 months of storage. For the main effect of treatment, ascorbic acid and n-acetylcysteine treatment produced pawpaw pulp that was significantly different than samples to which air was not excluded for all seven dependent color variables. Specifically, n-acetylcysteine and ascorbic acid produced pulp that was lighter (higher L*), less red (lower a*), and more yellow (higher b* and hue), more vivid (higher chroma), and exhibited more color difference (higher E). A strategy to inhibit enzymatic browning during frozen storage would be useful for the nascent pawpaw industry.

“…However, we have shown that the amount of total phenolics in pawpaw pulp was not affected by the level of ripeness, but that the level of total flavonoids was 40% higher in underripe pawpaw compared to ripe, which was 12% higher than in overripe pulp (Harris & Brannan, 2009). The level of total phenolics reported in pawpaw (9.2 lmol gallic acid equivalents per gram fresh fruit) (Harris & Brannan, 2009) are similar to several commercially important Annonaceous fruits, including soursop/guanábana/graviola (3.22 (Almeida et al, 2011) to 16.5 (de Souza, Pereira, Queiroz, Borges, & Souza Carneiro, 2012), sugar apple (4.80 (Almeida et al, 2011)), and cherimoya (5.8 (Barreca et al, 2011)). Mass spectral characterization of individual polyphenolic compounds from commercially important fruits of the Annonaceae family is limited, as only two studies could be located.…”

“…Mass spectral characterization of individual polyphenolic compounds from commercially important fruits of the Annonaceae family is limited, as only two studies could be located. These studies reveal that two categories of flavonols, condensed tannins and flavan-3-ols predominate (Barreca et al, 2011;Huang, Cai, Corke, & Sun, 2010). In sugar apple pulp, low levels of procyanadin dimer (B-type), (+)-catechin, and quercitin were identified .…”

“…Por último, cabe destacar también que en la provincia de Granada el cultivo de la chirimoya es cada vez más importante, siendo este el primer fruto de carácter tropical que se implantó en la zona. Es cada vez más apreciado por sus excelentes propiedades sensoriales y por ser fuente de compuestos bioactivos (García et al, 2016), al ser España el primer país productor del mundo (Barreca et al, 2011).…”

La descomposición de la hojarasca es una de las principales vías de consumo de energía en un ecosistema y uno de los pilares básicos en el ciclo de nutrientes. Por otro lado, en las últimas décadas, los cultivos subtropicales se han expandido de forma considerable en la costa de Granada (sureste de España). Para evaluar dichos ciclos se llevó a cabo un ensayo con bolsas utilizando para ello hojas de mango (Mangifera indica L.), chirimoyo (Annona cherimola Mill.), aguacate (Persea americana Mill.) y níspero (Eriobotrya japonica L.). El objetivo de este trabajo fue realizar un seguimiento de la dinámica de descomposición de las hojarascas producidas por el mango, aguacate, chirimoyo y níspero, y de la evolución de su contenido en carbono y nitrógeno en condiciones de clima mediterráneo subtropical. Las bolsas fueron enterradas y se recuperaron cada cierto tiempo para evaluar la concentración de carbono y nitrógeno, así como la pérdida de masa en cada una de ellas. Los resultados de este estudio mostraron de forma evidente que los agricultores pueden beneficiarse del conocimiento de la dinámica de nutrientes en hojarasca para mejorar la materia orgánica en el suelo a largo plazo y la incorporación de nitrógeno. En este sentido, el níspero y el mango mostraron las mayores tasas de acumulación de nitrógeno y, por lo tanto, la biomasa de estas especies podría ser utilizada como enmiendas de tipo orgánico a largo plazo. Por el contrario, el chirimoyo acumuló mayores cantidades de carbono que el resto de los cultivos estudiados.
