Encapsulated Tartaric Acid

Encapsulated tartaric acid refers to tartaric acid embedded in food-grade, GRAS-certified wall materials such as maltodextrin, gum arabic, modified starch, cyclodextrin and plant-based lipids.As a controlled-release acidulant, it completely overcomes the inherent defects of conventional tartaric acid, addressing core pain points in sensory experience, processing stability, formulation compatibility, production efficiency and regulatory compliance for food and beverage manufacturers. It is widely applicable to confectionery, baked goods, carbonated drinks, jams, ready-mix powders and fortified functional foods.

Eliminates Abrupt Sharp Sourness & Effectively Masks Off-Notes

Normal tartaric acid dissolves instantly and releases a sharp, harsh sour sensation the moment it touches the tongue, overpowering sweet, fruity or creamy notes. This creates an unbalanced sensory experience, especially in high-end hard candies, fruit jellies, low-sugar juices and dairy-containing products. Manufacturers have to overuse sweeteners or flavor maskers to compensate, which compromises clean-label positioning and consumer palatability.

The microcapsule shell enables slow, controlled release of tartaric acid, triggered by chewing, saliva dissolution or pH changes. It delivers a mild, long-lasting tartness instead of a harsh initial kick, balancing sweetness and fruit flavors perfectly. This creates layered, natural tasting profiles ideal for premium confectionery, fruit beverages and baked fillings, while reducing reliance on excessive sweeteners.

Improves Heat Stability & Prevents Acid Loss during Thermal Processing

Normal tartaric acid is highly acidic and reactive, causing multiple formulation problems:

①　It denatures dairy and plant proteins, leading to curdling, stratification and gritty textures in milk drinks, plant-based beverages and creamy sauces.

②　It forms insoluble precipitates with calcium, iron, zinc and other mineral ions, making fortified drinks cloudy and uneven.

③　It accelerates the degradation of natural pigments (anthocyanins, carotenoids), causing fading and discoloration in fruit juices and preserves.

④　It speeds up CO₂ escape in carbonated drinks, resulting in flat, less fizzy products with a short shelf life.

The protective capsule wall physically isolates tartaric acid from reactive ingredients, preventing direct contact and all adverse reactions. This maintains the smooth texture of protein-based products, the clarity of fortified beverages, the vibrant color of naturally colored goods and the fizz stability of carbonated drinks—critical for high-quality, visually appealing end products.

It prevents precipitation, discoloration and nutrient degradation, maintaining the clarity of functional beverages, the smooth texture of supplements, and the activity of probiotics, vitamins and creatine. This greatly simplifies the development of complex multi-ingredient formulas such as electrolyte drinks, multivitamin powders and creatine-protein blends.

Eliminates Hygroscopic Caking & Boosts Production Efficiency

Normal  tartaric acid is highly hygroscopic. It absorbs moisture easily during storage and automatic feeding, causing caking, clumping and sticking. This clogs dosing machines, mixers and packaging lines, requiring frequent downtime for cleaning and maintenance. Uneven dispersion also leads to raw material waste as high as 8–12%, along with inconsistent acidity in finished goods.

The capsule shell forms a moisture-proof barrier, making encapsulated tartaric acid non-hygroscopic and free-flowing. It feeds smoothly into fully automated production lines without caking or blockages, reducing raw material waste to below 1%. This cuts downtime, streamlines workflow and ensures precise, consistent dosing in every batch.

Ensures Uniform Dispersion in High-Viscosity & Complex Systems

Normal tartaric acid disperses in high-viscosity matrices such as jams, pastry fillings, thick syrups and gummy gels. It tends to clump and create localized "sour hot spots," resulting in uneven taste and poor consumer experience. Extended mixing times are required to improve dispersion, increasing energy consumption and production costs.

Encapsulated tartaric acid exists as uniform, fine micro-particles that disperse evenly in water-based, oil-based and high-viscosity systems without settling or agglomeration. It achieves consistent acidity throughout the product without extra mixing steps, making it suitable for nearly all complex food and beverage formulations.

Expands Formulation Compatibility to Oil-Based Systems

Normal tartaric acid is only water-soluble and cannot be used in oil-based products such as chocolate fillings, nut butters, oil-based marinades and fatty sauces. Manufacturers must source extra oil-soluble acidulants, increasing formulation complexity and raw material costs.

By using lipid-based wall materials, encapsulated tartaric acid can be engineered for oil-phase compatibility. It works equally well in water-based and oil-based systems, eliminating the need for multiple acidulants and simplifying formulation design. This opens up new application scenarios for tartaric acid in previously inaccessible oil-based product categories.
