Premium biotechnological enzymes and extracts optimized for peak bio-availability and metabolic efficacy.
Established in 2002 and located in the High-Tech Zone of Xi'an, Shaanxi Province, Shaanxi ShineHerb Biotech Co., Ltd. is a globalized, research-driven enterprise specializing in the production, purification, and export of high-grade enzyme preparations, natural plant extracts, vitamins, amino acids, and key pharmaceutical intermediates.
With over two decades of robust industrial experience, we deliver superior value by supplying premium, highly standardized lactase and other biochemical preparations to more than 50 countries across Europe, North America, and Southeast Asia. Our strict dedication to structural stability, activity preservation, and clinical purity sets us apart as a first-tier enzyme source.
An authoritative guide to substrate affinity, degradation kinetics, and industrial stabilization of β-galactosidase.
Lactase (systematically known as beta-D-galactosidase; EC 3.2.1.23) is a highly specialized hydrolase that breaks down the disaccharide lactose into its constituent monosaccharides: D-glucose and D-galactose. In human physiology and industrial processes, this enzyme targets the β-1,4-glycosidic bond of lactose. Without optimal enzymatic activity, lactose passes undigested into the large intestine, causing osmotic imbalances, bacterial fermentation, and the associated symptoms of lactose intolerance.

Under industrial conditions, lactase activity is quantified in FCC Units (Food Chemical Codex) or ALU (Acid Lactase Units). Achieving stable activity requires maintaining precise pH levels and temperatures. Neutral lactases (typically derived from the yeast Kluyveromyces lactis) require a pH of 6.5 to 7.0 and are ideal for fresh dairy products. In contrast, acidic lactases (sourced from filamentous fungi like Aspergillus oryzae) work best at a pH of 3.5 to 5.5, making them highly effective for dietary supplements and digestive capsules that must survive gastric conditions.
ShineHerb Biotech uses a state-of-the-art technical roadmap to maximize enzyme yield and maintain long-term stability:
We use non-GMO strains of Kluyveromyces lactis and Aspergillus oryzae to prevent mutation and ensure consistent, high-yield enzyme production.
Our multi-stage membrane filtration removes metabolic byproducts, concentrating lactase without exposing it to high temperatures that could damage the enzyme.
We apply advanced spray-drying and micro-encapsulation techniques to protect the enzyme, preventing degradation and ensuring a long shelf life.
As a leading bulk exporter, ShineHerb Biotech designs optimized lactase formulations for three main industries:
Quality is the foundation of our business. We enforce strict standards at every stage of production.
ShineHerb Biotech has established a strict quality management system, covering raw material inspection, production process control, solvent and excipient management, and final product testing, ensuring rigorous quality control at every stage.
We provide full technical documentation and application assistance, helping customers optimize enzyme reactions, adjust pH levels, and maintain activity under various processing conditions.
All production lines operate under strict GMP requirements, ensuring clean, contamination-free processing that meets the highest safety standards for the global market.
Our advanced manufacturing facility in Xi'an integrates automation and real-time monitoring to ensure consistent enzyme activity and high purity. Using digital bioreactor controls, we track fermentation parameters—such as oxygen levels, temperature, and feeding rates—in real time to optimize production.
This automated system reduces batch-to-batch variation, allowing us to supply large quantities of stable lactase to global buyers on tight schedules. With end-to-end traceablity, every batch can be tracked from raw material input to the final packaged enzyme.
By combining raw material control with automated processing, we offer stable pricing and high-quality enzymes that meet USP, EP, and FCC standards, even during market fluctuations.
Our production lines and products comply with strict international standards, ensuring clean, safe, and reliable ingredients.
