Chemistry is the scientific discipline involved with compounds composed of atoms, i.e. elements, and molecules, i.e. combinations of atoms: their composition, structure, properties, behavior and the changes they undergo during a reaction with other compounds. Chemistry addresses topics such as how atoms and molecules interact via chemical bonds to form new chemical compounds.
squash requires a brief heat treatment, called blanching, in boiling water or steam, to destroy the enzymes before freezing. Cook (blanch) the squash for 3 minutes. Begin counting the blanching time as soon as you place the squash in the boiling water.
Questions: (a) do I need to blanch zucchini before or after grating, before freezing? (b) should grated zucchini be colandered and squeezed before bagging and freezing, or should extra moisture be left in? and (c)does zucchini need an additive, such as lemon juice, to keep from discoloration?
