Amortization is the gradual repayment of a debt over a period of time, such as monthly payments on a mortgage loan or credit card balance. To amortize a loan, your payments must be large enough to pay not only the interest that has accrued but also to reduce the principal you owe.
Freeze the zucchini until ready to use. Blanched zucchini can be frozen for 9 to 14 months depending on how airtight the seal is and how cold the freezer is kept. After thawing out the zucchini, use it within 3 days and do not attempt to re-freeze it.
The food saver vac advertises as long as 5 years when properly packaged in the freezer which I can only attest to 4 years since that is as old as my machine and I just pulled out some zucchini and fried it. It was a little soft after the thaw but came out as good tasting as it went in.
