(2012) compared different mills and commented about energy savings when using a roll mill. only a few studies were conducted to examine the specific energy requirements of mills (bitra et al., 2009, mohapatra and bal, 2007). however, no research report had been directed at the energy requirements during cone milling of roller asim kumar samanta, likun wang, ka yun ng, paul wan sia heng 5 2014is magnesium stearate harmful or harmless: 6 supposed dangersmagnesium stearate is a salt that is produced when a magnesium ion bonds with two stearate molecules. stearate is just the anion form of stearic acid, which youve most likely heard of before. stearic acid is a longchain saturated fat that is abundant in beef, cocoa butter, coconut oil, and other natural foods. as i mentioned in my red meat article, its also the only longchain saturated fat that scientists and medical practitioners agree doesnt raise cholesterol levels, and doesnt increa see full list on chriskresser one study that many people have used as evidence against magnesium stearate is a 1990 experiment entitled molecular basis for the immunosuppressive action of stearic acid on t cells. this baffles me, and i suspect that anyone using this study to indict magnesium stearate hasnt actually read it.in the experiment, scientists isolated tcells and bcells from mice, put them in a petri dish, and bathed them in a solution containing stearic acid (along with some other components). they observed see full list on chriskresser another criticism is that because stearate is often derived from cottonseed oil, it can be contaminated with pesticides. keep in mind that magnesium stearate is a highly purified substance, and goes through an intensive refining process before appearing in your supplements. so far, i havent come across any reports indicating that magnesium stearate retains substantial amounts of pesticide residue.as for the concern that cottonseed oil is often genetically modified, the source of crude fat sh see full list on chriskresser another criticism is that magnesium stearate might inhibit nutrient absorption. one in vitro study conducted in 2007 found that tablets containing magnesium stearate dissolved more slowly than tablets without magnesium stearate when placed in artificial gastric juice.
