Yeast Autolysis
Yeast milk is added to an autolysis reactor and slowly heated to 85–95°C under continuous stirring, maintaining this temperature for 0.5–2 hours for autolysis. This stage utilizes the autolytic enzymes inherent in the yeast to gradually rupture the yeast cell wall, fully releasing intracellular proteins, nucleic acids, and other soluble nutrients. This provides abundant substrates for subsequent enzymatic hydrolysis, improving extraction efficiency and product yield.
First Stage Complex Enzymatic Hydrolysis
After autolysis, the yeast milk is cooled to 60–70°C, and the pH is adjusted to 6.5–7.0. Yeast extractant, papain, and alkaline protease are then added, and hydrolysis is carried out at a constant temperature for 8–12 hours. This stage primarily utilizes the synergistic effect of multiple proteases to gradually break down large protein molecules in the yeast into smaller peptides and free amino acids, improving protein utilization and promoting the release of umami precursors.
Second Stage Enzymatic Hydrolysis
After the first stage of enzymatic hydrolysis, the resulting hydrolysate is cooled to 40–50°C, and the pH is adjusted to 4.5–5.5. Then, acidic protease, neutral protease, and nuclease are added, and the enzymatic hydrolysis reaction continues for 10–20 hours. This stage further degrades residual proteins, peptides, and nucleic acid components. Nuclease promotes the hydrolysis of nucleic acids to generate flavor nucleotides, enhancing the umami flavor of the product and improving its solubility and nutritional composition.
Flavor-Directed Enzymatic Hydrolysis Optimization
After the second stage of enzymatic hydrolysis, the hydrolysate is reheated to 50–60°C, and the pH is adjusted to 5.5–6.5. Glutaminase, flavor protease, and deaminase are added, and the targeted enzymatic hydrolysis reaction continues for 10–20 hours. This stage mainly promotes the further conversion of flavor precursors, increases the content of umami amino acids such as glutamic acid, optimizes peptide composition, and enhances the natural umami flavor and overall flavor quality of the yeast extract.
Enzyme Inactivation and Solid-Liquid Separation
After flavor enzymatic hydrolysis, the hydrolysate is heated to 75–85°C and maintained for 0.5–2 hours for enzyme inactivation treatment, completely deactivating all enzyme preparations, terminating the enzymatic hydrolysis reaction, and ensuring stable product quality. After inactivation, the material undergoes solid-liquid separation to remove undissolved particles and cell residues, obtaining a clear and homogeneous yeast extract, providing a stable raw material for subsequent concentration and drying processes.
Concentration and Spray Drying
The separated yeast extract is concentrated according to process requirements to increase the soluble solids content. Then, a spray drying process is used to rapidly dry the concentrate into powder. After sieving, packaging, and quality inspection, the spray-dried product yields a yeast extract powder with good flowability, easy water solubility, and stable quality, meeting the application needs of food, condiments, nutrition and health, and other fields.
is yeast extract powder good for skin ?
Yeast extract powder, rich in amino acids, small peptides, flavor nucleotides, B vitamins, and yeast-derived polysaccharides, supports normal skin metabolism and is suitable for various skincare product formulations, including moisturizing, repairing, soothing, anti-aging, and brightening. It is a highly sought-after natural functional ingredient in cosmetics and personal care products.
- Moisturizing: Yeast cells contain abundant natural moisturizing factors (NMF) and minerals, which help maintain the stratum corneum's moisture balance, reduce transepidermal water loss (TEWL), support the skin barrier function, improve dryness and roughness, and keep skin supple. Yeast-derived β-(1,3)/(1,6)-glucan and mannan have good hydrophilicity, helping to enhance skin's moisturizing ability and strengthen barrier protection.
- Whitening: Studies have also shown that the active peptides and other bioactive components in yeast extract can improve skin tone evenness by promoting keratinocyte renewal and reducing melanin transepidermal transfer, supporting brightening of skin tone and improvement of skin texture.
- Anti-aging: In addition, yeast extract has certain antioxidant activity, which can help eliminate free radicals and reduce the impact of oxidative stress on the skin, thereby helping to maintain skin elasticity and improve fine lines and photoaging.
yeast extract powder benefits
yeast extract powder for salt reduction
Studies have shown that various naturally occurring small peptides in yeast extract can participate in the regulation of saltiness perception. Some saltiness-enhancing peptides can enhance saltiness perception in low-salt systems and prolong the duration of saltiness by interacting with saltiness-related receptors, thus helping to maintain the overall flavor performance of products while reducing the amount of sodium chloride added. Furthermore, some peptides also exhibit a regulatory effect on saltiness intensity under higher salt concentrations, demonstrating a certain degree of bidirectional saltiness regulation.
With its naturally rich content of flavor peptides, free amino acids, and flavor nucleotides, yeast extract powder can produce a synergistic flavor-enhancing effect with food formulations, supporting the development of products such as meat products, condiments, convenience foods, plant-based foods, and compound seasonings, while meeting consumer demands for clean labels and healthy eating.
yeast extract powder for hair
In recent years, yeast-derived active ingredients have received increasing attention in the fields of scalp care and hair care. Studies have shown that yeast fermentation extracts, rich in amino acids, small peptides, and other bioactive components, can support the hair follicle microenvironment by regulating oxidative stress and inflammation-related pathways. In cell and animal studies, yeast fermentation complex extracts can activate the NRF2 signaling pathway related to cellular antioxidant defense, while inhibiting NF-κB signaling and NLRP3 inflammasome activation associated with inflammatory responses, thereby mitigating the effects of oxidative stress on dermal papillary cells (DPCs).
Furthermore, studies have observed that it can promote the expression of hair follicle growth-related factors such as IGF-1, Wnt3a, and Wnt10b, and enhance β-catenin signaling stability, which is associated with hair follicle entering the anagen phase and enhanced hair follicle activity. These findings suggest that yeast-derived active ingredients have the potential to support scalp health, improve the hair follicle microenvironment, and promote healthy hair growth.
