supervenusfreak will often buy a large number of items when they’re on sale and freeze them to use over time. We recently started Weight Watchers, so he did this with Promise non-fat margarine. We thawed one of the tubs today and realized that we had a soupy, sloshy mess on our hands. Too late, we noticed that the package had “Do Not Freeze” on it.
So why can’t you freeze non-fat margarine. My personal guess is that it’s because they cut the fat with water, forming an emulsion. The freezing freezes the water before the fat, and the emulsion breaks so the whole thing separates into a mess when it’s thawed.
That sounds exactly right. The first ingredient in the spread is water, then mono- and diglycerides.
Be aware that the Promise nutrition facts is misleading. The regulations only require that triglycerides be listed on the label as ‘fat.’ Mono and diglycerides provide the same amount of calories per gram as triglycerides but you are never told how much of either the spread contains and they are not included in the calorie calculation.
Like all things with a lot of water, they can be flash frozen, with dry ice.
Slow freezing allows the formation of ice crystals, which become droplets.
