MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS

CAS: 977093-29-0 EMULSIFIER OR EMULSIFIER SALT

MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS is a food emulsifier and emulsifier salt used to help stabilize oil-water mixtures in various processed foods.

What It Is

MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS is an ingredient used in food processing classified functionally as an emulsifier or emulsifier salt. Emulsifiers are substances that aid in forming stable mixtures of ingredients that ordinarily separate, such as fats and water. This compound belongs to a broader class of food emulsifier derivatives that include esters formed from glycerides with organic acids and neutralizing counterions like sodium and calcium. These derivatives can improve product uniformity and texture by lowering interfacial tension and enhancing dispersion of fatty phases. The CAS number 977093-29-0 uniquely identifies this compound in chemical registries. While this specific complex mixture is denoted separately, its role correlates technically with lactic acid esters of mono- and diglycerides, which are recognized food additives used internationally in food products for their emulsification properties. Its classification as an emulsifier salt reflects the presence of ionic counterions that further support its solubility and function in aqueous food systems. In regulatory inventories such as the U.S. Food and Drug Administration’s (FDA) Substances Added to Food database, this substance appears in listings of ingredients that have been reported for food use, indicating it is known to food regulatory authorities and industry. Its functional identity as an emulsifier situates it among surface-active agents that modify the way fats and water interact, improving consistency and product quality. Emulsifiers like this additive are widely used across many formulations, especially where fat and water phases must remain uniformly distributed throughout shelf life. Because detailed toxicological and exposure data specific to this named compound are limited in public regulatory summaries, broader classes of related glyceride esters inform safety considerations and usage decisions.

How It Is Made

The manufacturing of MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS follows general principles used for related glycerol derivative emulsifiers. In food ingredient production, mono- and diglycerides are typically prepared by controlled glycerolysis of triglycerides sourced from edible fats and oils or by esterification reactions involving glycerol and specific fatty acids. For lactic acid esters, lactic acid is reacted with mono- and diglycerides to form lactylated glycerides. Following esterification, the resulting product undergoes neutralization with food-grade sodium and calcium sources to create the corresponding salts. The resultant material is refined and purified to meet food-grade standards, with specifications commonly defined by international compendia such as Codex and national food additive monographs. The conditions used in production, like temperature and catalysts, are designed to yield a mixture of lactylated mono- and diglyceride esters with the desired functionality. Because this substance is a mixture rather than a single molecular species, analytical characterization focuses on overall properties such as ester content, free glycerol, free fatty acid content, and lactic acid incorporation. Purification steps are implemented to remove undesirable byproducts and to ensure it meets appropriate food additive specifications for safety, purity, and performance. International specifications published for related compounds describe acceptable ranges for key parameters to ensure consistent performance and minimal impurities. These processes are standardized enough that manufacturers can produce emulsifiers reliably, but proprietary differences in raw materials and processing can influence the final composition within allowed technical limits. Industrial-scale production facilities adopt quality control processes to ensure compliance with food additive regulations, including testing for residual solvents, heavy metals, and conformity with identity and purity criteria. Because the production involves reaction and neutralization steps, control of pH and byproduct removal are critical to achieve a stable, well-characterized additive suitable for food applications. The sodium and calcium salts in the mixture can affect solubility and functionality, which is why neutralizing agents are selected to meet performance needs across different food matrices.

Why It Is Used In Food

MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS is used in food because of its emulsification and stabilizing properties. In many processed foods, fats and oils must be dispersed in aqueous phases or vice versa; without effective emulsification, products can separate, resulting in poor texture, appearance, and consumer acceptance. Emulsifier additives facilitate the formation and maintenance of stable dispersions by reducing surface tension and supporting the distribution of one phase within another. This improves product uniformity, mouthfeel, and overall quality. In addition to emulsification, this type of additive can support dough handling and gas retention in bakery products, improve the texture and creaminess of dairy and non-dairy products, and maintain consistency in sauces and dressings. Its functionality can also influence product shelf life by helping to inhibit phase separation during storage, which is particularly important for products that undergo temperature fluctuations or extended shelf life. Manufacturers select emulsifiers like lactic acid esters of mono- and diglycerides when specific functional attributes such as aeration, stability at varying pH levels, or interaction with other ingredients like proteins are desired. Because this compound combines lactic acid esters with sodium and calcium counterions, it may offer nuanced performance differences compared to neutral emulsifiers alone. Sodium and calcium salts can contribute ionic characteristics that may enhance interaction with certain food components. The choice of this additive in a formulation balances technical performance with regulatory acceptance, supply availability, and cost considerations. It is often chosen when formulators need reliable emulsification in complex systems, and its use fits within industry-standard practices for processed foods.

Adi Example Calculation

To illustrate how an ADI might be considered in practical terms, imagine a hypothetical food additive with an ADI of 10 mg per kilogram of body weight per day. For a person weighing 70 kilograms, this would translate to a theoretical allowable intake of 700 mg of that additive per day. Because the ADI for lactic acid esters of mono- and diglycerides has been described as "not limited," this example shows how ADI values are used in principle; it does not apply directly to this specific additive. Instead, regulators rely on detailed evaluations and the designation of ADI status to inform how food additives are permitted and monitored within food systems. In real-world settings, actual intake levels of emulsifiers like lactic acid esters of mono- and diglycerides are influenced by food formulation practices and typical consumption patterns. Dietary exposure assessments help regulators estimate how much of an additive consumers might ingest from various foods and ensure that such intakes remain within safety expectations under normal use conditions. This approach supports public confidence in the safety of permitted food additives.

Safety And Health Research

Regulatory evaluations of lactic acid esters of mono- and diglycerides and related emulsifier salts have focused on ensuring that typical food exposures do not raise safety concerns when consumed as part of a varied diet. Organizations like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) conduct scientific assessments incorporating toxicology, metabolism, and exposure data. These assessments consider whether the compound or its metabolic constituents are likely to pose risks at levels consistent with intended use. For lactic acid esters of mono- and diglycerides, JECFA established an ADI described as "not limited," indicating no safety concerns under conditions of good manufacturing practice, within constraints for related esters in mixed additive exposures. Toxicological evaluations typically examine endpoints such as general toxicity, organ health, potential for genotoxicity, reproductive and developmental effects, and metabolism. In the case of ester emulsifiers like lactic acid derivatives, metabolic pathways generally yield glycerol, lactic acid, and fatty acid components that are also common dietary constituents. Because these breakdown products are metabolized through normal physiological pathways, they are not considered to present inherent toxicity at typical intake levels. Regulatory safety evaluations emphasize the importance of purity and avoidance of unintended contaminants, as these can influence safety profiles. Consumers may encounter emulsifier additives in many foods, and regulatory authorities maintain surveillance of scientific literature and post-market data to ensure safety standards remain appropriate. Current authoritative evaluations support the safe use of emulsifier classes like lactic acid esters of mono- and diglycerides when used according to good manufacturing practice.

Regulatory Status Worldwide

The regulatory status of MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS aligns with how related lactic acid esters of mono- and diglycerides are treated by major food safety authorities. In the European Union, lactic acid esters of mono- and diglycerides of fatty acids are permitted for use as food emulsifiers and assigned the E number E472b, reflecting their approval under EU food additive legislation. This indicates the compound category is recognized and authorized for general food use within EU member states. The E number designation E472b corresponds specifically to lactic acid esters of mono- and diglycerides in EU food additive lists, and this category is widely used across food applications. Internationally, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) evaluated lactic acid esters of mono- and diglycerides and established an Acceptable Daily Intake (ADI) of "not limited" under conditions that the total intake of related esters such as tartaric acid derivatives remains within specified bounds. This ADI "not limited" designation indicates that, based on available data at the time of evaluation, this class of emulsifiers did not raise concerns at typical dietary exposures under good manufacturing practice. The FAO/WHO combined compendium of food additive specifications provides specification monographs and safety evaluation context for these materials. In the United States, specific regulations for this named compound are not found in Title 21 of the Code of Federal Regulations; related compounds like mono- and diglycerides have been affirmed as generally recognized as safe (GRAS) for food use with no limitations other than good manufacturing practice. The FDA’s Substances Added to Food inventory lists products known for food use, including emulsifier derivatives, without implying specific limitations. Because MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS is functionally similar to established emulsifier categories, its use is understood within the broader regulatory acceptance of analogous compounds.

Taste And Functional Properties

MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS does not contribute significant flavor of its own at the levels used for emulsification, but it can influence the sensory profile of foods by modifying texture and mouthfeel. Functional properties of emulsifiers like this involve their ability to weaken the interfacial tension between immiscible phases, such as oil and water, and thus stabilize fine droplets within a continuous matrix. This leads to smoother textures and consistent structural integrity in products such as creams, sauces, bakery fillings, and batters. From a sensory perspective, products formulated with effective emulsifiers tend to have improved creaminess, reduced oily or greasy sensation, and a homogenized appearance that contributes positively to consumer perception. The presence of lactic acid esters may also subtly influence how fat disperses, contributing to a perception of fullness or richness without altering inherent flavor profiles. The sodium and calcium components do not typically impart noticeable taste at functional use levels but can enhance solubility and compatibility with other ionic components in a formulation. In terms of physical behavior, this class of emulsifier is generally dispersible in hot aqueous environments and integrates well into oil phases, allowing it to perform across a range of processing conditions. It supports heat stability to some extent and can function across varying pH environments typical of many processed foods. As a result, formulators value emulsifiers like this for their versatility and consistent performance in complex food systems where texture, appearance, and shelf stability are priorities.

Acceptable Daily Intake Explained

An Acceptable Daily Intake (ADI) is a regulatory concept that represents the amount of a substance that can be consumed daily over a lifetime without appreciable health risk, based on scientific evaluations. Regulatory bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) assess toxicology and exposure data to determine an ADI. For lactic acid esters of mono- and diglycerides, the ADI has been characterized as "not limited," which means that evidence evaluated did not identify safety concerns at typical levels of intake consistent with their use in food, provided that related ester intake limits are respected as outlined in combined additive specifications. It is important to understand that an ADI is not a recommendation to consume a specific amount; rather, it is a safety threshold used by regulators when setting permitted uses. ADIs support risk assessment by indicating that, under normal dietary patterns and approved uses, consumers are not expected to exceed amounts that could pose health risks. Manufacturers and regulatory agencies use ADIs in combination with good manufacturing practice to ensure that foods containing emulsifiers remain within safe consumption bounds for the general population.

Comparison With Similar Additives

MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS functionally resembles several related food emulsifiers used across the food industry. For example, citric acid esters of mono- and diglycerides (INS 472c) are another class of esterified emulsifiers often chosen for their ability to enhance aeration and foam stability in bakery products. Compared to lactic acid esters, citric esters may offer slightly different interactions with proteins and starches, leading formulators to select one over the other depending on desired textural outcomes. Another comparison is with sodium stearoyl lactylate (SSL), a specific lactylate salt that has dedicated regulatory listings in some jurisdictions. SSL contributes to improved dough handling and gas retention in baked goods and is often used at low levels to support crumb structure. Calcium stearoyl lactylate (CSL) similarly provides dough strengthening and emulsification benefits but can differ in solubility and ionic interaction due to the calcium counterion. While MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS represent a broader mixture including both sodium and calcium forms, SSL and CSL illustrate how single-counterion lactylates are tailored for specific applications. These comparisons show that emulsifier selection depends on formulation needs—texture, stability, interaction with other ingredients, and processing conditions. Each emulsifier class brings distinct functional nuances even as they share core capabilities in stabilizing fat-water systems.

Common Food Applications Narrative

MONO- AND DIGLYCERIDES, LACTIC ACID ESTERS AND SODIUM AND CALCIUM SALTS, like related emulsifier compounds, is applied across a broad range of processed foods where the stabilization of fat and water phases is essential. In baked goods, emulsifiers help to distribute fats uniformly throughout batters and doughs, improving volume, crumb structure, and texture. They aid in mixing and can support gas retention during baking, which in turn contributes to the lightness and consistency of breads, cakes, and other leavened products. In dairy and non-dairy emulsified products such as creamers, toppings, and sauces, effective emulsification ensures a smooth, uniform product that resists separation over its shelf life. Without reliable emulsifiers, products that contain both water and fats can separate into discrete phases, negatively affecting appearance and consumer acceptance. Emulsifiers like lactic acid esters of mono- and diglycerides also play important roles in confectionery, where they can improve texture and prevent bloom in chocolate-like products, as well as in dressings and spreads where creamy mouthfeel and stability are desired. Furthermore, emulsifiers are used in frozen desserts to enhance air incorporation and to support texture during freeze-thaw cycles. Processed meats and meat analogs benefit from emulsifiers to maintain moisture and fat distribution, contributing to juiciness and uniformity. The application of such emulsifiers illustrates why they are integral to modern food manufacturing, where product consistency, sensory quality, and extended shelf life are key consumer and industry priorities.
