Processed Foods
The ever-increasing sophistication of food technology and the advent of number labeling means that it is becoming increasingly difficult for the average consumer to know what ingredients make up the items they wish to buy.  Many seemingly innocent products, such as yogurts, may contain gelatine, spices may contain stearic acid salts, and even breakfast cereal may contain glycerine.  Expensive production equipment is rarely allowed to stand idle, and may well be used to process non-kosher foodstuffs as well as kosher.  It is therefore essential that extensive use is made of this kosher handbook.
