Introduction
Dehydration techniques have come a long way in recent years. Old technology left as much as 30% moisture in the dehydrated products. Nor did these poorly dehydrated foods store very well. With present technology, moisture levels have been reduced to 2% or 3%. Gone are the pliable dehydrated foods. Now they break with a crisp "snap" when bent. With moisture levels reduced to 2%-3%, storage life has been increased to several years. In doing background work for this study, I opened up a can of dehydrated carrots and another can of onions that were 8 years old. They had each been stored for at least 3 of those years in a warm garage. During the last five years they were in our basement food storage room. During a careful taste test I could not tell the difference between the items 8 years old and the freshly dehydrated carrots and onions. Next, I opened a can of potato flakes we've had in our food storage for the last 15 years. This can of potato flakes has followed us around for what seems like numberless apartments and homes, sometimes stored well and sometimes not. How did they taste? Really nice and fresh. --- continued at link, above ---
