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.
1 Slice the squash into 1/2 inch slices. 2  Prepare quickly to prevent discoloring before you freeze the squash. 3  Place the summer squash slices into the boiling water for three minutes to blanch. 4  This process will destroy bacteria and enzymes in the vegetable, making it safe to freeze the squash for future consumption.
