Watch Your Garden Grow - Beans
Fresh pole beans and bush beans can be stored, unwashed in plastic bags in the vegetable crisper of the refrigerator for up to 3 days. Do not wash them before storing. Wet beans will develop black spots and decay quickly. Wash beans just before preparation.
Green beans can be frozen, dried or canned. Immature beans retain more color and undergo less texture and flavor loss during freezing. All vegetables must be blanched before freezing. Unblanched vegetables quickly become tough and suffer huge nutrient and color loss. Vegetables naturally contain an active enzyme that causes deterioration of plant cells, even during freezing. Blanching before freezing retards the enzyme activity.
Freezing does not improve the quality of any vegetable. Freezing actually can magnify undesirable characteristics. For instance, woodiness in stalks become more noticeable upon thawing. Select vegetables grown under favorable conditions and prepare for freezing as soon after picking as possible. Vegetables at peak quality for eating will produce best results in the freezer.
