Vegetable green soybean is one of the most important vegetable crops imported into Japan. If production in Japan decreases and Taiwan and China cannot supply more frozen green soybean for early markets from January to March at a reasonable cost, then Japan will be forced to look at other countries to fill in the already existing demand which is believed to be approximately 10,000t. Australia is in a very sound position to fulfil the demand in both vegetable green soybean and seed for Japan. This project was undertaken to assess and determine methods to enhance and improve the production of vegetable green soybean for the domestic market and trial shipments to Japan. This project achieved high recognition from Japanese markets regarding the potential of the Australian green soybean industry. The cultural postharvest package and IQF freezing technology were developed for commercial purposes but would also be useful for the Australian horticultural industry.
