ALPHA-GALACTOSIDASE FROM MORTEIRELLA VINACEAE RAFFINOSEUTILIZER

CAS: 977080-39-9 ENZYME

Alpha-Galactosidase from Mortierella vinaceae raffinoseutilizer is a food enzyme preparation permitted in the United States for specific processing applications under 21 CFR 173.145, mainly used to aid sucrose production from sugar beets by removal of mycelia after use.

What It Is

Alpha-Galactosidase from Mortierella vinaceae raffinoseutilizer is a microbial enzyme preparation used as a food processing aid. It consists of the enzyme alpha-galactosidase, derived from the mycelial microorganism Mortierella vinaceae var. raffinoseutilizer, and is identified by the CAS Number 977080-39-9. The technical function of this additive is as an enzyme preparation, meaning it catalyzes specific biochemical reactions during food processing rather than being an active nutritional ingredient itself. In regulatory inventories, this enzyme is listed under enzyme preparations permitted for use under defined conditions in the United States. Alpha-galactosidase enzymes in general are glycoside hydrolases that catalyze the hydrolysis of alpha-linked galactosides into simpler sugars. Although alpha-galactosidase activity is found across a variety of organisms, this specific preparation refers to the enzyme harvested from the growth and fermentation of the Mortierella vinaceae var. raffinoseutilizer strain. In the context of food processing, the enzyme serves a strictly technological role and is used under controlled conditions where the enzyme is removed from the final product through filtration or other separation steps. For classification, the enzyme is not a flavoring or nutrient in the finished food but a processing aid. Because processing aids are not intended to remain in the final food at functional levels and are removed during production, they are treated differently from food ingredients that remain in significant quantities. This distinction reflects its status within regulatory frameworks, where its safety and permitted uses have been assessed with respect to intended technological applications rather than dietary exposure as an ingested nutrient.

How It Is Made

The production of alpha-galactosidase from Mortierella vinaceae raffinoseutilizer begins with the cultivation of the nonpathogenic fungus Mortierella vinaceae var. raffinoseutilizer under controlled fermentation conditions. In a fermentation process, the microorganism is grown in a nutrient medium optimized to support high levels of enzyme production. Factors such as temperature, pH, oxygenation and nutrient availability are controlled to promote robust growth and consistent enzyme expression. Once fermentation has reached the desired level of enzyme activity, the biomass and culture medium are processed to recover the enzyme preparation. After the fermentation phase, the enzyme can be separated from the microbial cells and culture medium using common downstream processes such as filtration, centrifugation and, in some cases, purification steps like ultrafiltration. These steps are designed to concentrate the enzyme activity and remove unwanted cellular debris or low molecular weight impurities. The resulting enzyme preparation may be formulated into a stable form, such as a liquid concentrate or dried formulation, appropriate for handling and use in food processing operations. Importantly, for food use as permitted under regulatory frameworks, the manufacturing process must ensure that the final enzyme preparation meets quality and purity specifications, such as those concerning microbial safety, absence of toxins and consistency of enzyme activity. Because this enzyme preparation is used as a processing aid, the production process also focuses on achieving a preparation that can be effectively removed from the food matrix after its intended role is complete. This includes ensuring that the mycelial biomass, if present, can be filtered out along with the spent culture medium after the enzyme has acted on the substrate. Ensuring reproducibility and control in manufacturing is key to both technological performance and regulatory compliance.

Why It Is Used In Food

Alpha-galactosidase from Mortierella vinaceae raffinoseutilizer is used in food processing to enhance technological efficiency, particularly in specific industrial applications such as sugar production. In the production of sucrose from sugar beets, the enzyme is added to molasses to break down complex sugars and other compounds that might otherwise reduce the efficiency of sucrose extraction. By catalyzing the hydrolysis of certain alpha-linked galactosides, the enzyme facilitates the release of sucrose and related sugars, potentially increasing the yield of commercially recoverable sucrose. The purpose of using this enzyme preparation in food processing is not to provide nutritional benefit or to alter the sensory characteristics of the finished food, but to improve process efficiency. When applied in the sugar beet processing context, the enzyme assists in modifying components of the raw material that might otherwise interfere with straightforward sucrose extraction. This can translate into economic benefits for processors by reducing raw material loss and enhancing overall process yield. Once its catalytic role is complete, the enzyme and any associated microbial biomass are removed from the product stream, typically through filtration or other separation technologies. This removal step is essential to comply with regulatory requirements that the enzyme not remain in the finished food at functional levels. Thus, the use of this enzyme is inherently tied to its role as a processing aid: it performs a function during production and is then removed, meaning that the final consumer food product does not contain the enzyme in active form. This approach to enzyme use is common in food processing, where enzymes such as proteases, amylases and other carbohydrate-modifying enzymes are employed in manufacturing but not intended to remain in the finished food.

Adi Example Calculation

Because no specific acceptable daily intake (ADI) value has been established for alpha-galactosidase from Mortierella vinaceae raffinoseutilizer in authoritative regulatory sources, and because this enzyme preparation is designed to be removed from the final food products, an illustrative numeric calculation is not applicable. In general regulatory practice, ADIs are calculated by identifying a no observed adverse effect level (NOAEL) from toxicological studies and dividing by a series of safety factors to ensure a wide margin of safety for human consumption. For example, if a hypothetical enzyme preparation had a NOAEL of X milligrams per kilogram body weight per day in a chronic toxicity study, and standard uncertainty factors totaling 100 were applied, the resulting ADI might be X/100 mg per kilogram body weight per day. In practice, such calculations require specific toxicological data and regulatory evaluation. Because alpha-galactosidase from Mortierella vinaceae raffinoseutilizer is a processing aid that is removed during production, consumer exposure is minimal and numeric ADI calculations are not typically established for this type of use. Instead, regulatory controls focus on ensuring the enzyme is used appropriately and does not remain in the finished food at functional levels.

Safety And Health Research

Alpha-galactosidase from Mortierella vinaceae raffinoseutilizer has been evaluated in the context of its intended use in food processing and permitted under U.S. regulations on that basis. Enzyme preparations generally undergo safety assessments focused on their production organism, the potential for allergenicity, and the likelihood of toxic or harmful impurities. Because this enzyme is used as a processing aid and removed from the final product, exposure of consumers to active enzyme or production organism residues is expected to be minimal. Regulatory assessments consider whether the parent microorganism strain is nonpathogenic and whether manufacturing controls ensure consistent quality and removal of unintended residues. Scientific research on alpha-galactosidases in general encompasses a broad range of enzyme sources and applications, including studies on structure, function and stability. However, specific toxicological studies for this Mortierella vinaceae-derived enzyme preparation in food context were not found in the available regulatory literature. In risk assessment frameworks, enzymes from well-characterized, nonpathogenic production strains are often considered lower risk relative to small molecules with systemic toxicological concerns, particularly when used in processing and adequately removed before consumption. Safety evaluation of enzyme preparations typically includes assessments of potential allergenicity due to proteinaceous nature of enzymes, although the risk is often mitigated by removal during processing and low exposure levels in the diet. In general, regulatory authorities rely on a combination of historical use data, microbial safety profiles, fermentation controls and analytical evidence of removal from final products to support safe use decisions. The absence of identified harmful effects in the context of authorized uses contributes to ongoing confidence in the safety of such processing aids under controlled conditions.

Regulatory Status Worldwide

In the United States, alpha-galactosidase from Mortierella vinaceae raffinoseutilizer is specifically permitted for use as a food additive under regulatory code 21 CFR 173.145. This section of the Code of Federal Regulations allows the use of this enzyme and its parent mycelial microorganism in defined food processing applications, subject to conditions that ensure it is removed from the finished product and does not persist at functional levels in foods reaching consumers. The regulation specifies the permitted microorganism strain and outlines that the enzyme and mycelial biomass must be removed, typically by filtration, so that no functional residues remain in the final sucrose product. This regulatory authorization reflects a risk assessment by the U.S. Food and Drug Administration that finds the enzyme preparation safe when used as intended in approved processes. No corresponding European Food Safety Authority (EFSA) authorization or E-number listing was identified in authoritative regulatory databases, and thus no formal approval status within the European Union regulatory framework can be confidently stated at this time. As such, its use in EU food processing may be subject to separate national authorizations or notification procedures under EU food enzyme regulations. Similarly, searches of international expert committees such as the Joint FAO/WHO Expert Committee on Food Additives (JECFA) did not identify a specific entry with numeric acceptable daily intake values or year of evaluation for this particular enzyme preparation, and thus no global JECFA monograph can be d. Regulatory frameworks outside the United States may treat enzyme preparations differently depending on regional food laws and definitions of processing aids versus food additives. In all cases where authorized, conditions of use and any labeling requirements are determined to ensure that the enzyme serves its technological function during processing and is not present at significant levels in foods consumed by the public.

Taste And Functional Properties

Alpha-galactosidase from Mortierella vinaceae raffinoseutilizer has minimal impact on taste, aroma or texture when used in food processing because it is not intended to remain in the finished product. Its primary functional property is catalytic activity, meaning it accelerates specific biochemical reactions without being consumed in the reaction itself. In the specific use case of sugar beet processing, the enzyme catalyzes the hydrolysis of alpha-galactosidic bonds in certain sugar-related compounds present in molasses. Functionally, alpha-galactosidases catalyze the cleavage of terminal galactose residues from complex sugars, aiding in the breakdown and release of simpler sugars for improved extraction efficiency. Because this enzyme preparation is used as a processing aid, its sensory properties in the food are generally irrelevant to the final product; any residual activity is intentionally removed to ensure that it does not contribute to organoleptic changes in the finished food. The enzyme itself does not have flavor characteristics that are relevant at the levels encountered during processing and is effectively absent from the final food. With respect to functional behavior in processing environments, the enzyme exhibits activity dependent on conditions such as temperature, pH and substrate availability. Enzyme performance tends to be optimized under specific process conditions determined by the food matrix and the surrounding environment in a processing plant. Stability of the enzyme under processing conditions is a key consideration for its effective use. Enzymes in industrial applications are typically selected and formulated for robustness under intended process temperatures and pH ranges, and manufacturing controls ensure that the enzyme retains sufficient activity to perform its function before being removed. However, because this enzyme is not consumed as part of food, and because it is removed after use, the stability and sensory effects in the finished food are not part of its functional evaluation. Instead, the focus is on ensuring that the enzyme performs reliably during the processing phase and can be effectively separated from the food matrix before final food products reach consumers.

Acceptable Daily Intake Explained

An acceptable daily intake (ADI) is a regulatory concept used to describe the amount of a substance that can be consumed every day over a lifetime without appreciable health risk. For many food additives and contaminants, regulatory bodies establish an ADI based on toxicological studies, usually with safety factors to account for uncertainties. In the case of alpha-galactosidase from Mortierella vinaceae raffinoseutilizer, a numeric ADI has not been established in authoritative regulatory databases, and no specific JECFA evaluation with ADI was identified in the available literature. As such, a numeric ADI cannot be provided here. It is important to understand that the ADI concept applies primarily to substances that remain in food at measurable levels and contribute to dietary exposure. Since this enzyme is used strictly as a processing aid and is removed to the greatest extent practical from the final food product, dietary exposure to the active enzyme from foods reaching consumers is expected to be negligible. When enzymes are used in food processing and then effectively removed, regulatory assessments focus more on the safety of the production organism and manufacturing controls rather than establishing an ADI for consumer intake. In general terms, an ADI is expressed as milligrams of substance per kilogram of body weight per day. It represents a level of exposure considered safe based on long-term studies and application of uncertainty factors. For processing aids like alpha-galactosidase, the absence of a defined ADI reflects both the limited exposure expected and the regulatory focus on ensuring that the enzyme is not present in functional amounts in the final food, thus obviating the need for a formal ADI in many jurisdictions. Therefore, while the ADI concept is central to many regulatory assessments, it is not applicable in a traditional sense for enzyme processing aids that are removed prior to consumption.

Comparison With Similar Additives

Alpha-galactosidase from Mortierella vinaceae raffinoseutilizer can be compared with other enzyme processing aids used in food manufacturing. For example, amylases are enzymes used to break down starches into simpler sugars in processes such as baking, brewing and starch hydrolysis. Like alpha-galactosidase, amylases are used during processing and are typically inactivated or removed before the final food product is consumed. Another example is proteases, which catalyze the hydrolysis of peptide bonds in proteins and are widely used in meat tenderization and cheese production. Proteases have specific functional roles in modifying food structure, much like alpha-galactosidase modifies carbohydrate structures during sucrose extraction. In both cases, the enzymes are chosen for their specific catalytic properties and are controlled during processing to achieve desired outcomes. A third comparison is with lactase, an enzyme that hydrolyzes lactose into glucose and galactose, often used in dairy processing to produce lactose-reduced products. Unlike alpha-galactosidase used as a processing aid that is removed, lactase may remain in the final product and contribute to the final composition of lactose-reduced milk or dairy products. This illustrates how different enzymes can have distinct roles: some are intended to remain active in the final food to achieve nutritional or functional changes, while others are removed after performing their process function. The differences in regulatory handling, expected exposure and technological intent reflect these varied use cases.

Common Food Applications Narrative

Alpha-galactosidase from Mortierella vinaceae raffinoseutilizer finds its primary application in industrial food processing contexts where specific carbohydrate breakdown is needed to improve manufacturing outcomes. The most well-documented use is in the production of sucrose from sugar beets. When sugar beets are processed to extract sucrose, certain complex sugars and oligosaccharides present in the raw material can interfere with straightforward sucrose recovery. By introducing alpha-galactosidase during the processing of molasses derived from sugar beets, manufacturers aim to break down these complex compounds, facilitating a higher yield of recoverable sucrose. After the enzyme performs its catalytic role, it, along with any microbial biomass, is removed by filtration or other separation techniques, leaving a clear sucrose product suitable for refinement and consumer use. Beyond sucrose manufacturing, enzymes similar to alpha-galactosidase are used in various food applications such as the processing of legume-based ingredients where galactooligosaccharides may be present, or in the breakdown of raffinose family oligosaccharides in certain plant-based raw materials. However, for Mortierella vinaceae raffinoseutilizer-derived alpha-galactosidase, the primary recognized application is tied to sucrose extraction processes. In these industrial applications, the enzyme’s role is part of a broader suite of processing aids that help modify specific components of the raw material to improve efficiency, consistency and yield of desired product fractions. In a typical processing scenario, the enzyme preparation is applied at a specific step in the production line under controlled temperature and pH conditions that favor its catalytic action. Once sufficient reaction has occurred, standard food processing separations ensure that the enzyme and any associated microbial matter are removed before the food product continues through refining, purification and packaging stages. Because the enzyme does not remain in the final food, its contribution is strictly technological. Common food categories that benefit indirectly from such enzyme use include refined sugars such as granulated sucrose, liquid sugar syrups and other sugar-rich products where improved extraction efficiency translates into more consistent and predictable production outcomes.
