Spoiling is not due directly to the action of air or of heat and it is not simply a chemical or a physical change. When vegetable materials ferment, decay, or turn sour, the spoilage is due to the growth of certain microscopic living organisms, or germs. These all belong to the vegetable kingdom and are divided into three groups: molds, yeasts, and bacteria. Familiar exam ples of each group are the blue-green mold of spoiled fruits, the yeast used in bread making, and the bacteria of the scum, or mother, of vine gar. What we see in compressed yeast, for instance, is simply a mass consisting of millions of germs. Individual germs are too minute to be seen without a microscope. Their activities cause the molding of jellies, the swelling and souring of canned fruits, the spoiling of canned vege tables, and the putrefying of meats. The character of the material largely determines which type of spoiling will occur. Acidity is favor able to yeasts and molds. Fruits may therefore spoil by yeast fermenta tion or become moldy. Most bacteria prefer a medium with little or no acid. Decay of vegetables or meats is therefore usually due to the action of bacteria. Neither fruits nor acid vegetables are favorable to the growth of most bacteria. Yeasts, molds, and bacteria are widely distributed and occur in the air, in water, on fruits and vegetables, and in great abundance in soil and dust. Hence at the time of canning not only the fruit or vegetable but also, the sirup or brine and the containers are more or less heavily contaminated with all manner of microorganisms.
