BiPRO whey protein isolate (WPI) is the first of a new generation of dairy ingredients, which combine superior nutrition, enhanced functionality, complete solubility, and neutral flavor.  BiPRO is a completely natural, unique dairy protein produced from pasteurized whey through proprietary selective ion exchange technology.  The unique ion-exchange process selects the primary functional and nutritional proteins – beta-lactoglobulin and alpha-lactalbumin – for isolation and spray drying.  In their pure form these functional whey protein groups can be used to replace much larger quantities of caseinates, soy protein, WPC, egg whites, or gelling agents.  Thus in formulas where nutrition, high gel strength, viscosity, aeration, water binding, or solubility are crucial, BiPRO can radically improve the nutrition and flavor of any food or beverage.  BiPRO provides the competitive edge, in terms of nutrition, functionality and flavor, for the introduction of successful, new products. 

Whey protein is a high quality protein source derived from milk and is the co-product in the manufacture of cheese.  Whey protein is a collective term that describes the cow’s milk proteins that are soluble in the low pH environment created when making cheese.  Whey protein isolates are defined as having >90% protein on a dry weight basis.  

Protein is an important nutrient needed by everyone on a daily basis.  It is made up of essential and non-essential amino acids, which are the “building blocks” for healthy bodies.  Proteins are necessary to repair body cells, to build and repair muscles and bones, to provide a source of energy, and to control many of the important processes in the body related to metabolism.

Nutritional Properties of BiPRO

BiPRO is a high quality, complete protein that delivers all of the essential amino acids needed by the human body, without carbohydrates and fat.  In addition to providing protein to the diet, many other health benefits have been attributed to consumption of whey protein.  Whey protein has been proven to have a positive effect in a number of areas including physical performance, weight management, immunity, and infant formula. 

Physical Performance and BiPRO
Whey protein initially gained popularity in sports nutrition products as a source of high quality protein and as a rich source of the branched chain amino acids (BCAA) isoleucine, leucine and valine, necessary for building muscle and lean body mass, and improving body composition and enhancing athletic performance.  BiPRO is a soluble, easy to digest whey protein that is quickly absorbed into the body to start rebuilding and repairing lean muscle tissue. 

Weight Management and BiPRO
BiPRO is a pure source of protein with little carbohydrate and fat, making it an ideal protein source for higher protein, lower carbohydrate/fat and low glycemic index diets.  Protein helps to stabilize blood glucose levels that are already within the normal range by slowing the absorption of glucose into the bloodstream.  This may reduce hunger by lowering insulin levels and making it easier for the body to burn fat.  BiPRO is also rich in the amino acid leucine, which research has proven to preserve lean muscle tissue while promoting fat loss.¹

Immunity and BiPRO
BiPRO helps support the immune system by helping to increase levels of the antioxidant, glutathione, which is required by the body for a healthy immune system.  This is very important in regulating immune responses in the body so they are appropriate in improving overall general health but not excessive (i.e. allergic reactions).  The sulfur-containing amino acids present in high levels within whey protein (in particular cysteine) enhance the production of glutathione which is a very important natural antioxidant produced in the human body and part of an effective baseline immunity within the body.  The immune system is one of the least understood and most important aspects in preventative and active disease fighting in the body.  Whey proteins appear to enhance the body’s immune system integrity and lend to better overall health.

Infant Formula and BiPRO
The nutrient composition of human milk is the “gold standard” for infant formula development.  Whey proteins are an ideal protein source to add to infant formulas to match the high concentration of whey proteins found in human milk and to take advantage of specific health benefits associated with specific whey proteins.  BiPRO is a pure, complete, high quality and highly digestible whey protein isolate with an excellent amino acid profile, containing all of the essential and nonessential amino acids, which can improve the overall protein quality of an infant formula and lower the total protein content.  BiPRO can be used to replace demineralized whey in regular infant formula on a protein basis.  BiPRO is rich in tryptophan (2.5g/100g product), which may increase the tryptophan content of the formula, which is very desirable.  BiPRO contains very little glycomacropeptide.  For this reason, it would not increase the level of threonine in the plasma as regular demineralized whey would.  The extremely low levels of residual minerals, milkfat and lactose allow the manufacturer better control of the mineral salts, vegetable oils and carbohydrates to add to the formula.  BiPRO may be suitable for use in formulations that require higher protein levels. The protein content of these formulas is higher than that of regular formulas, i.e. about 2.8-3.0g per 100 calories.  The advantages of BiPRO cited above are applicable and even more important for preterm infant formulas.  BiPRO typically contains less than 0.5g lactose per 100g powder and therefore may be appropriate for lactose-free infant formulas.
