If you intend to use the zucchini later than 7 days, place the air-tight plastic bag in the freezer. Freezing will cause the zucchini to lose its texture, but will be suitable in baked or stewed dishes. Stored property, zucchini will maintain freshness for 5 to 7 days. If stored for a longer duration, it will quickly lose freshness and will eventually secrete all of its moisture. After a week, the bag could be filled with green water.
