Whey Protein Isolate 90% (WPI90) by Glanbia

Whey protein isolate is a milk-derived protein that is obtained during the cheese making process. With its high protein content, essential amino acids, and low levels of lactose, carbs, and fat, it is widely used in sports nutrition, infant nutrition, and clinical nutrition to increase protein content, enhance texture, and reduce fat and calories in food and beverage products.

Added Benefits:

• High protein content
• Essential amino acids
• Low in lactose, carbs, and fat

Characteristic Features:

• Milk-derived
• Versatility in Use.
• High- Quality Product

Whey Protein Isolate: An overview

Whey Protein Isolate (WPI) is a high-quality protein derived from whey, the liquid by-product of cheese production. It undergoes a filtration process to remove most of the fat and lactose, resulting in a protein powder that is 90% or more protein by weight.

WPI is rich in essential amino acids, making it an excellent source of protein for muscle growth and repair. It is widely used in sports nutrition products, functional foods, and beverages due to its quick absorption and high protein content.

WPI is also popular in the pharmaceutical and cosmetic industries for its health and moisturising benefits.

Applications of Whey Protein Isolate

In Food Industry:

• Sports Nutrition: WPI is widely used in sports nutrition products like protein bars, shakes, and beverages due to its high protein content and quick absorption, which helps in muscle recovery and growth.
• Functional Foods: It is used in the production of functional foods, such as fortified cereals, snacks, and dairy products, to enhance their nutritional value.
• Bakery: WPI is used in bakery products like bread, cookies, and cakes to improve texture, moisture retention, and protein content.
• Dairy Products: It is used in the production of dairy products like yogurt and cheese to boost protein content and improve texture.
• Meat Products: WPI is added to meat products like sausages and burgers to improve texture, juiciness, and protein content.

In Beverage Industry:

• Protein Drinks: WPI is a key ingredient in protein drinks and shakes due to its high protein content, neutral flavor, and solubility.
• Fortified Beverages: It is used in fortified beverages like smoothies and health drinks to enhance their protein content and nutritional value.

In Pharmaceutical & Nutraceutical Industry:

• Medicinal Purposes: WPI is used in the pharmaceutical industry to formulate protein supplements for patients with protein malnutrition or those in need of additional protein intake.
• Nutraceuticals: It is used in the production of nutraceuticals and dietary supplements due to its high protein content and health benefits.

In Cosmetics Industry:

• Skin Care Products: WPI is used in skin care products like creams and lotions for its moisturizing and anti-aging properties.
• Hair Care Products: It is used in hair care products like shampoos and conditioners for its nourishing properties.

Whey Protein Isolate production process

The production process of Whey Protein Concentrate 80 (WPC 80) involves several steps:

1. Collection and Filtration: Whey is collected as a byproduct of cheese production and undergoes initial filtration to remove large particles.
2. Pasteurization: The whey is then heated to a specific temperature to kill any harmful bacteria.
3.  Ultrafiltration: The whey is passed through a series of ultrafiltration membranes to separate the protein from the lactose, fats, and minerals. This process helps concentrate the protein content.
4. Ion Exchange or Microfiltration: The whey protein concentrate is further processed using ion exchange or microfiltration methods to isolate the protein from the remaining components.
5. Removal of Lactose: Additional filtration or enzymatic treatment may be used to reduce lactose content further, making the product suitable for lactose-intolerant individuals.
6. Spray Drying: The lactose removed whey protein is then spray dried into a powder form. During this process, the liquid whey is sprayed into a hot chamber, where the water evaporates, leaving behind the dried protein powder.
7. Packaging: The dried WPI powder is then packaged into containers or bags for distribution and sale.

Throughout the production process, quality control measures are implemented to ensure the final product meets safety and quality standards.

Price and Availability trends of  Whey Protein Isolate

The price and availability of Whey Protein Isolate can vary depending on factors such as market demand, production costs,Import duties, changes in import laws, treaties or international trade laws & supply chain logistics.

Whey Protein Concentrate vs Whey Protein Isolate: A comparison

Whey Protein Concentrate (WPC) and Whey Protein Isolate (WPI) are two popular forms of whey protein, differing mainly in their protein content and manufacturing process. Shorten with AI

WPC typically contains around 70-80% protein along with some lactose and fats. It retains more bioactive compounds, such as immunoglobulins and lactoferrin, which may have health benefits. Shorten with AI

WPI, on the other hand, undergoes further processing to remove more of the lactose and fats, resulting in a product that is 90% or more protein by weight. This makes WPI a better option for those who are lactose intolerant or looking for a protein with higher protein content per serving. Shorten with AI

However, WPI tends to be more expensive than WPC due to the additional processing involved. Both forms of whey protein are popular for their high quality, fast digestion, and ability to support muscle growth and recovery.Shorten with AI

Frequently Asked Questions about Whey Protein Isolate:

How is Whey Protein Isolate made?

Whey Protein Isolate is made by filtering whey to remove most of the fat and lactose, followed by drying to create a powder that is at least 90% protein.

Is Whey Protein Isolate good for health?

Yes, whey protein isolate is good for health, as it is a high-quality protein source that can aid in muscle building, weight management, and overall health when consumed in moderation.

Are there any side effects of Whey Protein Isolate?

Yes, here are the possible side effects of WPI:

1. Some people may experience bloating, gas, or diarrhoea due to extreme lactose intolerance or sensitivity to whey protein isolate.
2. Individuals with milk allergies may experience allergic reactions to whey protein isolate, leading to symptoms like hives, swelling, or difficulty breathing.
3. Excessive consumption of protein supplements may put strain on the kidneys, especially in individuals with pre-existing kidney conditions.
4. Very high protein intake over a long period may potentially lead to liver damage in some individuals.
5. Consuming large amounts of protein supplements can lead to imbalances in minerals like calcium, which may affect bone health. 

Is Whey Protein Isolate lactose free?

Yes, it is not mostly lactose-free and only contains trace amounts of lactose, making it a suitable option for individuals who are lactose intolerant, although some extremely sensitive individuals may still experience issues.

Is Whey Protein Isolate vegan?

No. It is sourced from animal milk. It is vegetarian, not vegan.
