Pulsin-Whey Protein Isolate Powder (1000g) Pulsinâ Whey Protein Isolate is one of the best quality proteins available from any food source, due to its full spectrum amino acid profile, rapid speed at which it can be assimilated during digestion and a protein content of 90%. Our whey protein is not to be confused with Whey Protein Concentrate: an inferior quality extract with a lower protein content, a cheesy taste and higher levels of lactose. Pulsinâ Whey Protein is produced from sweet whey, a natural by-product from cheese manufacturing where milk is separated into curds (casein) and whey. The whey protein is isolated using a combination of Cross-Flow Ultrafiltration and Microfiltration techniques, which preserves the delicate structure of the whey protein without causing denaturation. The resulting protein isolate is then mixed with soya lecithin to improve miscibility with other foods. All of our whey protein is produced from UK milk from grass fed cows that have been reared without hormone treatment and is 100% vegetarian. Whey protein can be mixed into a variety of foods, including yogurt, breakfast cereals, flapjacks and cakes. We do not recommend cooking whey protein at high temperatures as it can become denatured by heat. Whey protein isolate is absorbed so effectively that some people prefer to combine it with another slower releasing protein to lengthen the duration of satiety and to give a sustained amino acid release into the bloodstream; this can be particularly effective when consuming protein before going to sleep. We find that whey protein and pea protein combine particularly well for this purpose, at a ratio of approximately 1:1, and hence we use them both in the Protein Sport bar!
