The lima bean is a green or light flat bean. It is use only for the seed, the pods being coarse or woody. Some lima beans are canned and they are handled in such the same manner as the frozen product except that they may or may not be passed through the quality grader.
In case it is the fresh beans, the beans are first washed carefully and stored. They are size-graded and then blanched in hot water at 88-95 °C – the amount of time depends upon the maturity of beans, varying from 2 to 3 minutes for young, tender beans to 7 or 8 minutes for more mature tougher beans.
The beans are automatically metered into cans. The filled cans pass to the briner where a boiling hot 2% salt brine is added to completely fill the can. The cans are sealed and heat-processed.
Some lima beans to be canned are allowed to mature and dry out on the vine before harvesting. In such cases, the beans must be soaked in water for purposes of rehydrating prior to further processing.
