Abstract
Yellow passion fruit cultivars developed or adapted regionally can contribute to the productivity and production increase of quality fruit taking care of the needs of the market and the remuneration to the producers. The aim of this study was to evaluate the physical and chemical characteristics of yellow passion fruits harvested at different maturation stages. Yellow passion fruits, cultivar BRS Gigante Amarelo, were produced in Terra Nova do Norte city, Mato Grosso state, Brazil. The experimental design was a randomized complete block, in 4 × 4 factorial scheme (maturation stages and evaluation periods), with four blocks. Physical (mass, length and diameter fruit and peel color) and chemical (total soluble solids, total titrable acidity and ratio) fruit characteristics were evaluated. The data were submitted to analysis of variances and the means were compared by the Tukey test at 5% probability. The fruits of yellow passion fruit cultivar BRS Gigante Amarelo harvested at different stages of maturation present an increase in the color indexes (chroma and Hue), total soluble solids content and ratio, and reduction of the titratable total acidity, as fruit maturation occurs. In addition, fruits harvested at all maturation stages present a condition of industrialization immediately or after 3 days of storage while fruits harvested at maturation stage 4 present more interesting color characteristics for in natura trade, regardless of the storage period.
Highlights
Apesar de o maracujazeiro-amarelo apresentar grande potencial de mercado nas diversas regiões produtoras do país, no estado de Mato Grosso essa cultura ainda se encontra em expansão

Summary
O Brasil destaca-se como o maior produtor e exportador mundial de frutos de maracujá, devido às condições edafoclimáticas favoráveis ao bom desenvolvimento da cultura. Cultivares desenvolvidas ou adaptadas regionalmente podem contribuir para o aumento da produtividade e da produção de frutos de qualidade, atendendo às necessidades do mercado e à remuneração dos produtores. Um fruto de qualidade é aquele que atende às expectativas dos diferentes segmentos consumidores em suas características internas e externas. As características internas estão relacionadas ao sabor (teor de açúcares e acidez) e ao conteúdo de suco (rendimento), sendo estes parâmetros utilizados pela indústria como critério de seleção dos frutos, enquanto as externas estão relacionadas à boa aparência (cor da casca, tamanho, peso, ausência de defeitos) e representam os parâmetros adotados pelo consumidor no momento da escolha (Aguiar et al, 2015). Mediante o exposto e visando contribuir com informações e, consequentemente, divulgar a cultura no estado de Mato Grosso, objetivou-se com este trabalho avaliar as características físico-químicas de frutos de maracujazeiro-amarelo colhidos em diferentes estádios de maturação
