    S To Making Whey Protein Powder

    Making whey protein powder is simple. The first few steps performed are the same, whether you are talking about whey protein or cheese making.

  • Pasteurization – fresh milk undergoes pasteurization.
  • Culture – milk is kept warm, and culture is applied along with mild agitation.
  • Coagulation – The culture produces “Adenosine triphosphate” from the milk’s lactose , creating lactic acid. The lactic acid then separates the curds from the whey . Curds are sticky casein proteins that form around fat globules. Whey is the watery substance that the curds float in.
  • Micro-Filtration – The whey is then pressured through a micro-filter to isolate out excess fat and lactose. Whey Protein Isolate stays in this filtering process longer, which results in a higher protein concentration. More importantly, as it pertains to the topic of side-effects, Whey Protein Isolate will contain very little if any lactose. Lactose-free WPI is very beneficial if you know your body’s limitations and sensitivities to lactose.
  • Spray Dried – The whey is then spray dried and tested for heavy metals and contaminants before being packaged.
  • When the discussion is about quality, like any form of food, if the quality is low, it’s not likely to bode well for your gut. Sourcing, in general, is critical in the supplement industry that operates utterly unregulated in terms of unverified quality and widespread marketing claims.
