The added gums absorb water and prevent it from refreezing into ice crystals.</p> Wed, 31 May 2017 14:27:13 +0000 OSS 2505 at /oss Is it true that ice cream that doesn’t melt easily should be avoided? /oss/article/controversial-science-food-health-quackery/it-true-ice-cream-doesnt-melt-easily-should-be-avoided <p>Joe Mercola, the font of much Internet poppycock, thinks that the safety of ice cream is somehow related to the ease with which it melts. He and other bloggers not well versed in science suggest that ice cream that does not melt easily should be avoided. There are ice creams that don't melt as readily as others but that doesn't mean that eating them poses a risk. There are a number of factors that determine how readily an ice cream melts. Basically, the melting rate is determined by the additives used. Ice cream is a mixture of fat globules, water, sugar and air.</p> Sat, 20 Jun 2015 10:25:19 +0000 Joe Schwarcz PhD 2268 at /oss
