honestly oats are tough to beat, we are going to be launching an oat powder, a rice dextrin/fiber and a few new starches that are going to give WMS a run for their money.
trehalose is a great carb as it acts differently, it is a disaccaride sugar, so it looks like sucrose, tastes like sugar (though it is not as sweet), but instead of having the large glycemic response like many sugars do, it does not induce as large as a glycemic response. we really like it as a replacement for dextrose and/or maltodextrin that many companies use in their MRPs. it will keep insulin levels within the body way more steady, but with that being said, oats, especially whole oats are tough to beat as a low glycemic carbohydrate. from a mixability, texture and taste standpoint trehalose is the way to go when looking for a lower glycemic carb that acts like sugar.
