Aspectos tecnológicos e sensoriais do guandu [Cajanus cajan (L.) Millsp.] enlatado em diferentes estádios de maturação

The objective of this work is to enable the introduction of canned green pigeon pea in Brazilian market. Three harvests of still green grains of the cultivar IAC Fava Larga, obtained on the 44th, 57th and 62nd days after flowering, DAF, and finally on the 92nd DAF when the grains already possessed yellowish dusky color, were undertaken. To all the lots, after optimization of canning conditions, 121oC for 5 to 6 minutes, studies concerning the accumulation of dry matter, grain composition, color, texture and sensorial acceptance were carried out. It was concluded through the accumulation of dry matter of the grain, that the physiological maturity occurred around the 62nd DAF. The texture was gradually firmer with advancing maturation, and positive correlation having been found (r = 0,96) between sensorial and instrumental texture measures was noticed. The acceptance of the canned pigeon pea cultivar IAC Fava Larga was only regular.
