Interpretive Summary: Food preparation methods may influence the stability and release of food bioactives. This study investigated the effects of different home food preparation methods on the availability of the total phenolic contents (TPC) and radical scavenging components, as well as the selected health beneficial compounds from fresh blueberries and carrots. High performance liquid chromatography (HPLC)analysis revealed that ground carrots using blenders released a significantly greater amount of ß-carotene than their chopped counterpart, and blueberry samples prepared with different commercial blenders/grinders released different levels of cyaniding-3-O-glucoside and malvidin-3-O-glucoside. Furthermore, microwaving was able to significantly alter the releasable amounts of cyaniding-3-O-glucoside and malvidin-3-O-glucoside from blueberries. In addition, carrots and blueberries processed using different blenders and chopping with or without microwaving differed in their available levels of TPC, and radical scavenging components against DPPH•, oxygen radicals and HO•, as well as their potential anti-inflammatory activities. Taken together, these results indicated that home food preparation approaches may alter the availability of health components from carrots and blueberries. The results also suggested that the influence may depend on the fruit and vegetable type, but not the price of blenders or grinders. The information may be used by food scientists and nutritionists, as well as consumers.
