Case Study in Mushroom Canning
Alan is the owner of Asia Canning Factory in Malaysia. He produces canned
mushrooms for export to Japan. Raw materials come from the countryside in 50-kg bags.
The mushrooms are weighed and then soaked in water to remove big particles of soil and
sand. After that the mushrooms will be washed in stainless steel drums 3 times. They
are then steeped in 3% brine solution. The mushrooms will then be boiled for one hour at
100oC and then cooled down by spraying water over them and steeping them into water.
After that the mushrooms will be checked to weed out the spoiled ones. They are later
washed one more time prior to canning. The cans will be weighed and filled with brine
solution (2% brine, 0.1% acetic acid). They will be heated for air removal and then
closed. The cans are now washed and heated for pasteurization. They are cooled down
by water and packed for distribution.
