“…comosus) stands out as one of the most important fruit crops in tropical and subtropical countries (Paull and Chen, 2003), especially in Brazil where it is widely cultivated, producing 1,762,938 fruits in 2014, ranking among the three largest world producers (IBGE, 2016). Despite its extensive production in Northeastern Brazil, the pineapple chain has several critical constraints that have limited its expansion to new markets, even inside the country (Martins et al, 2012). In this context, postharvest losses are the main concern, which are related to its high perishability that contributes to its short postharvest life , and especially those related to physiological disorders such as internal browning (Luengwilai et al, 2016).…”

“…However, it presents a short postharvest life (Martins et al, 2012). Some efforts have been directed to extend postharvest conservation using cold storage and associated technologies such as plant regulators (Zhang et al, 2015), modified atmospheres , and polysaccharidebased coating (Lima et al, 2012).…”

Pineapple is a tropical fruit of great consume demand. However, due to its high perishability at room conditions, there is noticeable loss of quality postharvest in a short period. In this context, the use of biodegradable coatings is a promising alternative for maintaining postharvest quality. Thus, the aim of this study was to evaluate the use of cassava starch-alginate based biodegradable coatings added with ascorbic acid and an elicitor on postharvest quality and conservation of 'Pérola' pineapple. Fruits were coated with: Cassava starch 1.5% + alginate 0.5%; cassava starch 1.5% + alginate 0.5% + ascorbic acid 0.18 %; cassava starch 1.5% + alginate 0.5% + elicitor, each added of 0.5% of glycerol as a plasticizer, and the control (uncoated fruits), following storage at room conditions (23 ± 1°C, 88 ± 2% RH). Pineapples coated with cassava starch-alginate associated with the elicitor (SE) or ascorbic acid (SA) kept lower levels of reducing and total sugars as well as better appearance and general acceptance (GA) during room storage for 18 days. According to the panelists, the determining factors for higher GA of 'Pérola' pineapple under these coatings were the sweetness, fresh like characteristics of taste and odor, and better appearance. Overall, the use of SE and SA coatings had a marked impact in maintained the quality during 18 days and did not adversely affect the sensory characteristics of 'Pérola' pineapple stored at room conditions.

“…Com o aumento da adubação potássica, mesmo na maior dose de N, houve redução da translucidez, apresentando ponto de mínimo de nota 2,38 (menos de 25% de translucidez) na dose de 400 kg ha Bhugaloo (1998) e Malézieux e Bartholomew (2003 estão de acordo em que doses elevadas de N podem aumentar a translucidez da polpa do abacaxi. Martins et al (2012) avaliaram a conservação pós-colheita de abacaxi Pérola, comparando frutos produzidos sob sistema convencional e sob produção integrada (PI) e observaram menor translucidez nos frutos da PI, que é um sistema mais equilibrado em relação às práticas de adubação, e consideraram que a utilização racional de insumos pode auxiliar na manutenção da integridade da parede celular. Portanto, inferese que maiores doses de adubo nitrogenado, sem a adequada adubação potássica, aumenta a translucidez do abacaxi 'BRS Imperial'.…”

RESUMO-A qualidade do fruto do abacaxizeiro é influenciada pelos macronutrientes, principalmente N e K. Este trabalho avaliou a influência de doses de N e K 2 O sobre as características de qualidade físico-químicas e sobre os defeitos externos e internos dos frutos de abacaxizeiro 'BRS Imperial'. Aplicaram-se quatro doses de n (0; 160; 320; 550 kg ha -1 ) e quatro de K 2 o (0; 240;480 e 600 kg ha -1 ), em delineamento experimental em blocos ao acaso, com cinco repetições, em um fatorial completo 4 2 . As doses de N e K 2 O influenciaram todas as variáveis físico-químicas estudadas, exceto a firmeza dos frutos, que apresentaram média de 10,7 kgf. QUALITY OF PINEAPPLE 'BRS IMPERIAL' AS A FUNCTION OF N-K DOSESABSTRACT -Pineapple fruit quality is influenced by macronutrients, particularly N and K. This study evaluated the influence of N and K 2 O doses on physicochemical quality attributes and on the incidence of external and internal defects of 'BRS Imperial' pineapple fruits. Four levels of N (0, 160, 320, 550 kg ha) and four of K 2 o (0, 240, 480 and 600 kg ha -1 ) were tested in a randomized blocks experimental design with five replicates, in a 4 2 full factorial scheme. The doses of N and K 2 O influenced all physicochemical variables, except fruit firmness that averaged 10.7 kgf. The N doses reduced titratable acidity (TA) and soluble solids (SS) and increased pH and fruits' ratio, with average values of 0.31%, 17.9 o Brix, 4.02 and 57.7, respectively, at 550 kg ha -1 of N. The K 2 o doses increased tA and SS and reduced the ratio of fruit, with average values of 0. 41%, 19.4 o Brix and 47.9, respectively, at 600 kg ha -1 of K 2 O. The pH quadratic response showed the minimum value of 3.95 at 273 kg ha -1 of K 2 O. Significant Pearson correlations indicated that plants with higher N leaf contents at the time of floral induction produced fruits with lower TA and SS, while plants with higher K leaf contents produced fruits with higher TA and SS. The application of 550 kg ha -1 of n, the fruits showed translucency between 50 and 75% without potassium fertilization and less than 25% at 400 kg ha -1 of K 2 o.

“…A cultivar 'Tommy Atkins' responde por 80% dos plantios de manga no Brasil em função de sua maior resistência a pragas e doenças, e por apresentar maior conservação pós-colheita (FONSECA et al, 2006). O Sistema de Produção Integrada (PI) minimiza o uso de agroquímicos, preservando o meio ambiente, assim como a saúde do consumidor e do produtor, assegurando a obtenção de frutos com alta qualidade (MARTINS et al, 2012). Em 2008, 47% da área total do Vale do Submédio São Francisco destinada à cultura da mangueira já havia aderido à PI (LOPES et al, 2009).…”

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.
