“…O desenvolvimento de recobrimentos biodegradáveis/comestíveis baseado na combinação de biopolímeros tem atraído a atenção devido à sua abundância e ao potencial de substituição em relação a alguns produtos petroquímicos na embalagem de frutos e hortaliças (KALIA;PARSHAD, 2014). Neste sentido, a combinação de quitosana com óleo essencial de limão reduziu a perda de massa e a incidência de podridões em morango (PERDONES et al, 2012), em uvas 'Moscatel' recobertas com quitosana com óleo de bergamota (SÁNCHEZ-GONZÁLEZ et al, 2011) e em mamão recoberto com quitosana (GALO et al, 2014) .…”

RESUMO -Este trabalho teve por objetivo avaliar a qualidade de manga 'Tommy Atkins' da Produção Integrada (PI) recoberta com fécula de mandioca (F) associada a óleos essenciais e quitosana. A manga foi colhida na maturidade comercial de pomar certificado na PI. Os recobrimentos foram: Controle; F a 3%; F a 3% + erva-doce a 0,9% (FED); F a 3%+ orégano a 0,5% (FO), e F a 2% + quitosana a 2% (FQ). As mangas recobertas foram mantidas por 20 dias a 12+1°C e 80 + 2% U.R. e, em seguida, transferidas para a condição ambiente (24+2°C; 75+4% U.R) por mais 12 dias, simulando a condição de mercado. A combinação FQ retardou o amadurecimento, mantendo a coloração, os teores de sólidos solúveis e de acidez, apresentando mangas com intenção de compra e sabor superiores ao controle. Termos para Indexação: Fluorescência da clorofila; Foeniculum vulgare, Origanum vulgare, recobrimentos comestíveis. QUALITY OF 'TOMMY ATKINS' MANGO FROM INTEGRATED PRODUCTION COATED WITH CASSAVA STARCH ASSOCIATED WITH ESSENTIAL OILS AND CHITOSANABSTRACT-This study had as objective to evaluate the quality of 'Tommy Atkins' mango from the Integrated Production (IP) coated with cassava starch (S) associated with essential oils and chitosan. Mango was harvested, at the commercial maturity, from a certified orchard by the Mango IP. The coatings were: Control; S 3%; S 3% + Foeniculum 0.9% (SF); S 3% + Origanum 0.5% (SO), and S 2% + Chitosan 2% (SCH). Coated mangos were stored for 20 days at 12+1°C and 80 + 2% RH and, following, transferred to room conditions (24+2°C; 75+4% RH) for more 12 days, simulating the marketing condition. The combination SCH delayed ripening, maintaining the coloration, soluble solids, and acidity contents, providing mangos with purchase intention and flavor higher than the control.

“…According to Pimentel et al (2011), total soluble solids (SST) well represent the fruit ripening and generally, a high SST content indicates a higher degree of fruit maturity. Moreover, for Pego et al (2015), this parameter is used by many authors as a characteristic that reflects the sensory quality of fruits.…”

Surveys carried out in different microregions of Maranhã o highlight papaya as one of the fruits with the postharvest losses estimates. In this context, this study aimed to analyze the Journal of Agricultural Studies 385 efficiency of plastic packaging on postharvest conservation of Hawaii papaya to instruct the Maranhã o retail market about viable alternatives to mitigate losses related to this fruit. The papayas were purchased from CEASA of Sã o Luí s and sent to the laboratory. Posteriorly, they were randomly separated into 65 groups of 2 units, and then, applying the coverings are made. The experimental design was completely randomized in a split-plot at 4x5 times, with four treatment control [(without packaging), plastic film (FP), hermetic-bag (SH), and perforated-bag (SP)] and five evaluation periods (3, 6, 9, 12, and 15 days of storage); four repetitions and 2-fruits per portion (tray). For the individual biometric characterization, was carried out the measuring of the longitudinal and transverse diameters, fresh mass, pulp yield, seed mass, firmness, and fruit mass loss. Furthermore, for chemical analysis, total soluble solids content, total titratable acidity, and pH were measured. It was found, at the end of the study, that the hermetic-bag is efficient for maintaining the loss of fresh mass, firmness, ripening, total soluble solids content, total titratable acidity, and pH, which are relevant attributes of quality for commercialization of the Hawaii papaya. Therefore, the use of the hermetic-bag is recommended to increase the postharvest shelf life of Hawaii papaya fruit under stored at room conditions and at least for 15 days.

Papaya is one of the most grown and consumed fruits in the world. However, post-harvest diseases are responsible for more than 50 % of losses, including anthracnose, caused by Colletotrichum gloesporioides, which promotes necrotic and rounded lesions and reduces fruit quality. Alternative products have been widely investigated in the control of pathogens. This study aimed at evaluating the efficiency of elicitors in the control of anthracnose, as well as their effect on post-harvest quality, in papaya fruits. The fruits were disinfested and immersed in acibenzolar-S-methyl, potassium phosphite, Rocksil®, Agro-mos®, Ecolife®, sterilized distilled water and prochloraz, inoculated with C. gloesporioides and stored. Potassium phosphite, Rocksil®, Ecolife® and prochloraz resulted in the smallest diameters of lesions, and, consequently, in a greater protection and enzymatic activity. The fruits treated with Rocksil® and Ecolife® maintained the lowest levels of soluble solids and titratable acidity. Potassium phosphite, Rocksil® and Ecolife® are effective in controlling anthracnose, do not change the appearance and preserve the post-harvest quality of papaya fruits, and, therefore, may be used as an alternative to commercial fungicides.
