1  Preparation Methods for Low-Molecular-Weight Hyaluronic Acid

Preparation techniques for 低molecular weight hyaluronic acid are increasingly diverse, currently achieved primarily through degradation and microbial fermentation pathways. Hyaluronic acid traditionally extracted from animal tissues or microbial fermentation yields products with a broad molecular weight range. Low molecular weight hyaluronic acid, however, typically refers to refined products within the 1×10⁴ to 5×10⁵ molecular weight range, offering superior solubility and application flexibility.

1.1   Physical Degradation Method

Within current hyaluronic acid production, physical degradation methods are gaining increasing attention as environmentally sound processes. This approach employs physical means such as thermal treatment, ultrasonication, microwave irradiation, or radiation to achieve controlled degradation of high molecular weight hyaluronic acid, yielding low molecular weight products within specific molecular weight ranges.

Comparative studies indicate that 異なるphysical degradation methods exert distinct 効果on product characteristics. For instance, microwave treatment enhances ultraviolet absorption properties, while thermal processing offers simplicity and a concentrated molecular weight distribution. Electron beam and γ-ray irradiation cause minimal structural alteration to the raw material, with a more random degradation process, making them suitable for diverse application requirements.

Physical degradation methods require no chemical additives, are environmentally friendly, and involve straightforward post-processing. The resulting products exhibit advantages such as narrow molecular weight distribution and excellent thermal stability. However, current limitations include extended processing times and constraints on large-scale application. Consequently, these methods are often combined with other degradation techniques in practical production to balance efficiency and product performance.

1.2   Chemical Degradation Methods

Chemical degradation represents one of the current standard processes for producing low-molecular-weight hyaluronic acid powder. It achieves controlled molecular chain cleavage under specific conditions through chemical reagents, enabling precise regulation of product molecular weight. Common methods include acid hydrolysis, alkaline hydrolysis, and oxidative degradation. In recent years, innovative techniques such as 視聴覚degradation have emerged, offering new developmental possibilities for this field.

Oxidative degradation processes, exemplified によって水素peroxide, allow flexible control of degradation rates through concentration adjustment and the addition of catalysts (such as CuCl₂). Conversely, electrochemical degradation, as an emerging physicochemical approach, can significantly reduce hyaluronic acid molecular weight within a short timeframe. Research indicates it effectively preserves the chemical structure of the raw material, offering high efficiency and cleanliness, with considerable industrialisation potential.

The advantages of chemical degradation methods lie in their short reaction times, low production costs, and strong control over molecular weight, making them suitable for large-scale production. However, these methods often involve harsh reaction conditions that may affect product structural consistency and present challenges in residue treatment. Consequently, in practical applications, manufacturers must rationally select and optimise process routes based on product applications and quality requirements.

1.3   Biological Degradation Methods

Enzymatic hydrolysis represents the mildest degradation approach, exerting minimal impact on hyaluronic acid structure and consequently preserving its biological activity. This method is employed to produce low molecular weight hyaluronic acid, and hyaluronic acid oligosaccharides can also be obtained through gel permeation chromatography separation. However, the limited availability and high cost of hyaluronic acid as a source significantly constrain its application.

Biological enzymatic hydrolysis, as an efficient and gentle process, is increasingly becoming a key technical pathway for producing low molecular weight hyaluronic acid. This method utilises specific enzymes to catalyse the cleavage of hyaluronic acid molecular chains, enabling precise control over product molecular weight while preserving the natural structure of the raw material. It offers the advantages of high specificity and low side reactions.

Traditional enzyme sources predominantly rely on animal tissue extraction, which is costly and constrained by scale limitations. In recent years, significant progress has been made in microbial enzyme production technologies. Enzymes produced by various Streptococcus species have been demonstrated to effectively degrade hyaluronic acid, substantially expanding the raw material sources and industrial viability of enzymatic hydrolysis.

Enzymatic hydrolysis operates under mild reaction conditions with minimal impact on product structure, better preserving hyaluronic acid's natural activity. It is suitable for producing high-purity, low-molecular-weight hyaluronic acid and oligosaccharide products.

1.4   Microbial Fermentation Method

Microbial fermentation has emerged as a core technology driving industry advancement due to its green, efficient, and highly controllable characteristics. Compared to traditional degradation processes, this technology enables precise molecular weight control directly 中fermentation. This eliminates chain structure disruption, activity loss, and chemical residue issues associated with subsequent degradation, ensuring the integrity of the product's natural structure and functionality from the outset.

Through strain selection, medium optimisation, and precise fermentation parameter control, microbial fermentation efficiently produces low-molecular-weight hyaluronic acid within specific molecular weight ranges, offering significant industrial advantages:

・Streamlined one-step production: Eliminates post-degradation processes, substantially shortening production cycles and reducing product losses from multiple stages;

・Precise molecular weight control: Flexibly adjusts molecular weight distribution via fermentation conditions such as temperature, pH, and additives to meet diverse application requirements;

・Green and sustainable: Utilises naturally derived agricultural components as culture media, reducing environmental impact and aligning with global sustainable raw material trends;

・Exceptional cost-effectiveness: Streamlined processes, reduced energy consumption and raw material wastage make it particularly suitable for large-scale, high-quality hyaluronic acid production.

In application, fermentatively produced low molecular weight hyaluronic acid demonstrates broad prospects:

・Functional skincare: Small-molecule hyaluronic acid offers superior permeability, enhancing the texture and efficacy of moisturising and repair products;

・Premium personal care ingredients: Used in serums, masks, and sprays to enhance delivery and absorption of active ingredients;

・Biomaterials innovation: Leveraging its excellent biocompatibility and film-forming properties as a carrier material for diverse biocompatible applications;

・ Functional household product expansion: Suitable for hair care, oral care, and similar products, enhancing mildness and functionality.

Microbial fermentation not only provides an optimal solution for producing low-molecular-weight hyaluronic acid powder but also offers downstream enterprises a raw material choice characterised by higher purity, more stable supply, and greater alignment with sustainable development imperatives.
