Automotive Developments 1600-The Dutch employed wind power to propel sail-mounted carriages which raced along at 20 mph and held scores of passengers. It is quite probable that both speed and load capacity were exaggerated. Later, small carriages were equipped with wind-mills, the mill vanes geared to the wheels. These were probably the first land vehicles to be propelled by

Many different ingredients and raw materials are processed to make chilled foods. At harvest or slaughter these materials may have a wide range of microbes in or on them. Some of them carry the micro-organisms that cause their eventual spoilage(e.g. bacilli or Lactic acid bacteria) whilst others pick them up during harvesting or processing

Chilled foods are foods which are cooled to a temperature above their freezing point and which need to be maintained at that temperature to preserve quality Generally such foods will lose value if frozen, and in many cases freezing will destroy them. From the refrigeration viewpoint, the range of foods regarded as chilled is very wide. In this chapter they are taken to include fresh fruits and vegetables, both temperate and tropical in origin, the whole range of meat, fish
