Bleach removes fatty acids from skin. Gloves must be worn
while washing beans. Wash bleach solution off if any contacts skin.

Green bean pods are delivered to the lab once a
week (currently Tuesday). Beans arrive in a variety of
packaging, but the usually are in either box or plastic
bag. Bean pods can be purchased from grocery stores if delivered
beans happen to be of extremely poor quality. Schnuck's
in Urbana most consistently has both the quality and quantity of
beans needed.

Beans must be checked for
quality before washing. Avoid keeping beans that are limp, mushy, or have dark green
water soaked spots (freeze damage), as these are signs that
fungal growth will quickly develop. If a
large portion of the beans are of poor quality, notify Daniel before discarding beans. |
 |
| Place the beans in a blue washing container. |
 |
| Fill with deionized water until most of the beans
are submerged. The beans float so they will not all be completely
under water. Add enough bleach to make an approximately 10%
solution. Swish the beans and water around to mix in the
bleach. Let beans sit for 10 min. |
 |
| Pour bleach solution off the beans and
rinse beans several times with deionized water, pouring off water between rinses.
|
|
| Spread beans out on paper towels to dry. It
is best to let them dry for 45-60 minutes in the hood with the fan
on. When the beans are dry, place in an open, dated bag in the
refrigerator. If beans still in the refrigerator from passed weeks
are unusable, discard them at this time. Leaving them in the refrigerator will cause the fresh beans to
decrease in quality. If it appears that there are more beans than will be needed
in the next week, see Daniel for instructions. |
