Yeast Extract Protein

Do You Know About Yeast Extract Protein?

Yeast extract protein is a high-quality complete protein found naturally in yeast. Yeast protein is made from the yeast Saccharomyces cerevisiae. The yeast is cultured, fermented, and centrifuged, then harvested. The resulting raw material is then subjected to processes such as nucleic acid removal, centrifugation, enzymatic hydrolysis, extraction, purification, separation, sterilization, and drying. Yeast protein has a DIAAS (Digestible Essential Amino Acid Score) of 0.95, which is close to that of whey protein and superior to soy protein, making it a high-quality protein. Yeast protein contains essential amino acids and has an amino acid profile close to the ideal protein level. The amino acid profile is well-balanced, making it easily absorbed and utilized. Furthermore, yeast extract protein is slow-digesting, allowing it to be fully digested and absorbed in the lower small intestine, making it a typical "slow-digesting protein."

Approximately 50% of the dry weight of yeast is protein, a high-quality, complete protein containing all nine essential amino acids and boasting a high digestibility. Compared to animal and plant-based protein supplements, yeast protein offers a differentiated new protein source with higher nutritional value, added value, and cost-effectiveness. As a result, yeast extract protein has been increasingly adopted by brands in functional foods such as protein bars, protein powders, and muscle-building powders, and is gaining popularity among consumers.

The Difference Between Yeast Extract Protein and Traditional Protein

Yeast, similar in shape to an egg, contains not only protein but also a rich source of minerals and B vitamins. Its "eggshell" also contains high-quality polysaccharide dietary fiber. The yeast protein extraction process preserves some of the yeast's original dietary fiber, minerals, and vitamins. The dietary fiber in yeast is primarily beta-glucan, which has a slightly different structure from the beta-glucan found in oats. Yeast beta-glucan has been shown to have beneficial health effects in immune regulation, gut health, and inflammation.

Compared to soy protein and whey protein, yeast protein shows unique potential for promoting overall health, with its advantages potentially focusing on gut health. Research suggests that yeast protein may be superior to soy protein and whey protein in promoting healthy gut architecture, reducing intestinal inflammation and oxidative stress, and optimizing the composition of beneficial gut bacteria. Yeast extract protein is not a simple protein substitute; rather, it represents a functional protein source with potential benefits in supporting gut health, combating inflammation, and regulating gut microbiota.

Functional Properties of Yeast Extract Protein

1. Solubility and Water Retention

Yeast extract protein has excellent solubility and water retention in most non-extreme environments. Vegetarian meat products containing yeast protein experience reduced water loss during cooking, resulting in improved tenderness and juiciness. This property suggests that yeast extract protein has advantages in food processing, such as vegetarian burgers, vegetarian sausages, and vegetarian dumplings, where it can improve flavor and impart a meat-like bite and texture.

2. Metal Ion Binding Ability

Protein itself can bind to positively charged metal ions. For example, yeast protein binds to calcium ions, forming calcium-containing proteins that can be transported and absorbed by the body, offering potential as a new source of calcium supplements.

3. Biological Activity of Yeast Protein Peptides

Peptides derived from yeast protein hydrolysis have demonstrated numerous health benefits, including antioxidant, cholesterol-lowering, antihypertensive, antidiabetic, immunomodulatory, and antibacterial properties. Antimicrobial peptides derived from yeast protein hydrolysis are currently being used as alternatives to chemical preservatives in the food industry.

What Are The Benefits Of Yeast Extract Protein?

Supplementing High-Quality Protein

Yeast protein is a complete protein, containing all nine essential amino acids in ratios close to the ideal values ​​recommended by the Food and Agriculture Organization of the United Nations. With a digestibility of up to 96%, it effectively replenishes the body's protein needs and promotes tissue repair and growth.

Maintaining Intestinal Health

Studies have shown that supplementing with yeast protein can increase the number of beneficial intestinal bacteria (such as Parabacteroides and Prevotella), improve the intestinal microbiome, and reduce chronic inflammation. It is beneficial for middle-aged and elderly people with weak gastrointestinal function and those with irregular diets. It selectively promotes the growth of beneficial intestinal bacteria, which contribute to overall metabolic health.

Anti-Inflammation and Immune Modulation

Components such as beta-glucan in yeast protein have immunomodulatory effects, reducing the secretion of pro-inflammatory cytokines (such as TNF-α), lowering oxidative stress levels, and helping maintain immune balance.

Maintaining Long-Lasting Satiety

It effectively promotes satiety, helps naturally reduce overall calorie intake, and supports weight management from the source.

Improves Blood Lipids

Yeast protein helps regulate blood lipid levels, lowering total cholesterol and "bad" cholesterol while raising "good" cholesterol, thereby maintaining cardiovascular health while managing weight.

Builds Muscle and Shapes

Its rich content of branched-chain amino acids (especially leucine) effectively promotes muscle synthesis and repair after exercise, helping to increase muscle mass and strength while reducing fat and creating a more toned physique.

Improves Endurance

Supplementing with yeast protein has been shown to improve athletic endurance, allowing people to sustain longer and perform better during high-intensity training.

Accelerates Recovery

It effectively slows muscle aging, accelerates recovery after exercise, reduces fatigue, and helps people get back to their next workout more quickly.

Applications of Yeast Extract Protein

As a new, high-quality protein with comprehensive nutritional value, efficient production, and environmentally friendly properties, yeast extract protein has been widely used in multiple industries.

Food Industry

In the food industry, yeast protein plays multiple roles. It is an ideal ingredient for high-end nutritional supplements (such as protein powders and protein bars), meeting the protein needs of specific populations. In plant-based foods (such as vegetarian meats and sausages), it significantly enhances meatiness and flavor, effectively masking beany flavors. It is also a premium ingredient in baked goods, dairy products, and beverages, improving texture, promoting fermentation, enhancing flavor, and enhancing product stability. Furthermore, it can be used as a natural seasoning to enhance the umami and nutritional value of foods.

Medical and Health

Beyond basic nutrition, the bioactive peptides in yeast protein (such as those with antioxidant, cholesterol-lowering, and immune-modulating properties) make it a valuable raw material for the development of functional foods and health supplements. Certain specific proteins, such as metallothioneins, have also shown potential to participate in human metabolism and detoxification, offering broad prospects as pharmaceutical raw materials.

Cosmetics and Animal Feed

The value of yeast extract protein extends to other sectors. In cosmetics, its extract helps improve skin condition with its moisturizing and anti-oxidation effects; in animal feed, as a high-quality protein source, it can effectively enhance the growth performance and immunity of animals.

Yeast Extract Protein vs. Other Proteins

Yeast extract protein is non-animal-derived and offers advantages over animal and plant proteins in terms of allergenicity, antibiotic residues, genetic modification risks, and religious taboos.

Yeast Extract Protein in the Sports Nutrition Market

In recent years, yeast extract protein has gradually emerged as a new type of sports nutrition supplement. Its market price is also lower than that of traditional whey protein powder. So, what are the effects of yeast extract protein compared to whey protein?

Protein Sources and Characteristics Comparison

Whey protein is a byproduct extracted from milk, isolated during the cheese-making process. It is characterized by its rich content of branched-chain amino acids (BCAAs) and rapid absorption, effectively promoting muscle recovery and growth after exercise, thus long dominating the sports nutrition supplement market.

Yeast extract protein is a plant-based protein obtained by fermenting brewer's yeast. Its amino acid profile closely matches human needs, resulting in a high protein utilization rate. Furthermore, as a low-sensitivity protein, it contains no lactose, making it suitable for lactose-intolerant individuals and vegetarians.

Absorption Characteristics and Suitable Applications

The 30 minutes after exercise is a critical window for protein supplementation. Whey protein dissolves and absorbs quickly, allowing amino acids to enter the bloodstream quickly, making it suitable for rapid recovery after intense training.

In contrast, yeast extract protein is absorbed more slowly, releasing amino acids over a period of 4-6 hours. This makes it a more suitable daily protein source, particularly for endurance athletes or those requiring a sustained protein supply.

It is important to note that regardless of the protein supplement chosen, combining it with carbohydrates (such as bananas or bread) can improve protein utilization and replenish energy expended during exercise.

Scientific Basis for Muscle-Building Effects

Currently, there is limited research specifically investigating the muscle-building effects of yeast protein, but existing studies have demonstrated its potential. A 2022 study published in the Journal of Functional Foods showed that mice supplemented with yeast extract protein showed improvements in muscle tissue and muscle fiber size, as well as changes in the composition of their intestinal microbiota, suggesting that yeast protein may indirectly affect muscle metabolism by regulating the gut microbiome.

A 2024 study published in Engineering Microbiology noted that yeast, as a protein production platform, offers advantages such as rapid growth and high safety, and holds great potential in the field of sports nutrition. However, further clinical research is needed to confirm the specific mechanisms and efficacy of yeast extract protein's muscle-building effects.

Price Analysis

The price advantage of yeast protein stems primarily from differences in production costs and supply chains:

Production Cost: Whey protein relies on animal husbandry, requiring significant land, feed, and water resources, and the extraction process is complex. Yeast extract protein, on the other hand, is produced through microbial fermentation, requiring less space, requiring a shorter cultivation cycle, and resulting in lower raw material costs.

Market Factors: Whey protein, as a mature product, carries a brand premium, while yeast extract protein, as an emerging product, faces limited market competition.

As a novel protein source, yeast extract protein offers price advantages and specific application scenarios. While its short-term muscle-building effects may not be as good as those of whey protein, it holds practical value as a sustainable protein supplement.
