It was investigated the consumption possibility of the soybean cultivar IAC PL-1 canned as green grain and its best harvest time for canning. Five harvests were processed from the 48th day after flowering (DAF) until extinction of the green coloration. The canning procedure started by pod bleaching, dehulling and canning. To the five lots obtained, a sixth lot was added to study the effect of storage. To qualify the six lots of canned grains, measures of weight, color, texture were done, as well as characteristics of canning liquid. Studies of the sensorial properties of canned grains to dimensionate both acceptance and aspect was performed. Canning was optimized to 121ºC with sterilization time around four minutes. Grains physiological maturity took place between 61st to 64th DAF. The heat process conserved the green color of canned grains and did not induce significant loss of the mass of grains; the firm texture of grains increased with maturation. The tasters showed good acceptance of the products and there was no preference concerning the maturation stages. The work concluded that green grains of soybean IAC PL-1 provide canned products with very good technical and taste characteristics. It was found that grains harvested at the conventional maturation point stored and canned obtained good taste acceptance, following that the cultivar IAC PL-1 is also suitable to consumption canned after storage.
