Food emulsifier blenders are expensive, if one of adequate quality is chosen, such as the almost $500 Vitamix 1363 CIA Professional Series. Food emulsifier blenders that come at more affordable prices, such as the $73.99 HealthMaster LWHM, tend to break down within a few months.
Food emulsifier blenders are from twice to three times as strong as the standard blender. In order to blend food into a puree that rapidly, preserving all its nutrients, antioxidants and fibers, the parts and motor need to be of high quality, which results in an expensive price of $500. Furthermore the quicker the blend, the less heat will be generated in the food. Too much heat destroys enzymes.
