Wet Preparation of Ultra-fine Powder of Carrot and Analysis Its Physical-chemical Properties
Carrot is a kinds of high nutrition vegetable. The powder of carrot is widely used in food engineering. In order to study processing optimum conditions of ultra-fine power of carrot by wet processing, carrot were washed, ultra-fine grinded and dried. Orthogonal test were made by using L9(34) with median particle diameter as index, investigating the influence parameters of grinding temperature, grinding times, gap of mill teeth and the ratio of solid to liquid. The results shown that the optimum processing conditions were as follows: grinding temperature 55℃ , grinding 2 times, gap of mill teeth of 10μm and the ratio of solid to liquid 1:3 (g/mL). The physical-chemical properties of ultra-fine power of carrot were as follows: median particle diameter 20μm, packing density 0.41g/cm3, water adsorption 5.65 g water/g powder . The wet processing was a suitable method for preparation of ultra-fine powder of carrot.
