High-Acid Fruit Concentrates in Preblends (Tablets/Powders): Handling & Processing
Tablets, stick packs, effervescent powders, and other dry formats are attractive in nutraceutical and functional categories: they’re lightweight to ship, stable on shelf, and convenient for consumers. But dry formats often struggle with one thing: taste. Acidity can be a useful sensory tool (it creates brightness and masks bitterness), yet many brands want that acidity to come from recognizable fruit sources rather than from a single isolated acidulant. That is where high-acid fruit concentrates—such as lemon, lime, cranberry, pomegranate, sour cherry, or certain berry systems— can play a role. These concentrates can contribute both fruit identity and acid structure, and they can help taste-masking. The challenge is that liquid concentrates are not naturally “dry friendly.” They can be sticky, hygroscopic, and difficult to dose into dry systems without creating clumping or flow problems. This guide explains the practical options for incorporating high-acid fruit concentrates into tablet and powder preblends, how to manage stickiness and caking, and what specifications and documentation matter when these ingredients are used in regulated or audit-heavy products.

Why high-acid fruit concentrates are attractive in dry formats
High-acid fruit concentrates can solve multiple problems at once: they deliver a recognizable fruit identity, provide acid “bite” that makes functional products feel refreshing, and help mask bitterness from vitamins, minerals, botanicals, and amino acids. They also support “cleaner label” narratives compared with synthetic flavor systems. In effervescent products, acidity is a core part of the experience, and fruit acids can make that acidity feel intentional. The tradeoff is that these ingredients are liquids with concentrated sugars and acids—so they require thoughtful conversion into a dry-compatible format or a controlled liquid-addition process.
Understand the core handling challenge: stickiness and hygroscopicity
Liquid fruit concentrates contain high solids. Those solids can be sticky, and they can attract moisture (hygroscopic behavior). When introduced into a dry blend without the right strategy, they can create clumps, smear on equipment, and reduce flowability—leading to dosing inconsistency in stick packs, capsule fills, or tablet presses. High-acid concentrates can also be corrosive at high concentration if handled improperly, so equipment compatibility and cleaning protocols matter. The entire strategy is to either (1) convert the liquid into a dry ingredient with the right carriers and process, or (2) design a controlled liquid-addition step that does not compromise flow and uniformity.
Three practical routes: dry conversion, granulation, or controlled liquid addition
Manufacturers typically choose one of three approaches: (A) Dry conversion (e.g., spray-drying or other dehydration with carriers) to create a powder ingredient; (B) Granulation/agglomeration where the concentrate is used as a binder to create free-flowing granules; or (C) Controlled liquid addition during blending to a base that can absorb the liquid without caking. Each route has tradeoffs in cost, sensory quality, and equipment requirements. The best route depends on your finished format: tablets and capsule fills often require excellent flowability and low moisture; stick packs can tolerate slightly more variation but still demand consistent fill weights.
Carrier and matrix strategy: the difference between a usable powder and a sticky mess
If the concentrate is converted into a powder, carriers and matrix design become critical. The carrier must absorb solids, reduce stickiness, and preserve flavor identity. In practice, the carrier system also affects mouthfeel and dissolution behavior in the finished product. Many dry fruit systems succeed because the carrier choice is aligned with the product’s use: fast-dissolve beverage powders need different behavior than tablets that are swallowed. The selection should also consider label constraints and consumer expectations. From a procurement perspective, define acceptable carrier and processing approaches so supply remains consistent.
Acid load and sensory design: use fruit acids to mask bitterness without harshness
High-acid fruit concentrates can help taste masking, but they can also make products feel punishing if overused. The objective is to use acid strategically: enough to brighten and distract from bitterness, but not so much that the product becomes mouth-puckering. In dry systems, acid perception can be sharper because there is less water present until reconstitution. That’s why reconstitution instructions and serving size matter: a stick pack in 250 mL water behaves differently than one in 150 mL. The best practice is to define your target sensory profile at the intended dilution and validate at scale.

Flowability, caking, and moisture control: the operational checklist
Caking and poor flowability are the main causes of line issues in dry products. High-acid fruit systems can exacerbate caking if moisture creeps in during production or storage. Practical controls include: tight moisture specifications on the dry ingredient, controlled humidity in production areas, appropriate packaging barrier for the finished product, and validated storage conditions. If your product includes hygroscopic actives (certain minerals) alongside fruit systems, risk increases. The formulation, processing, and packaging must be treated as one system.
Color stability in powders and tablets: anthocyanins and browning risks
Berry-based high-acid concentrates may carry anthocyanin pigments that can shift with pH and processing conditions. In powders, color can fade if oxygen and moisture exposure are high. Browning can also occur over time depending on the sugar profile and storage conditions. If color is a key consumer cue, protect it with packaging barrier and minimize oxygen exposure. And specify incoming materials to reduce batch-to-batch color drift.
For anthocyanin behavior and pH-driven hue shifts, see Topic 073.
Documentation and specs: powder applications still require COA and traceability discipline
Even though the finished product is dry, documentation requirements in nutraceutical and regulated channels remain the same: COA, traceability, allergen statements, and micro posture. If the fruit concentrate is converted to a powder via a third-party process, you need to know where that conversion occurs and how change control is handled. Define which specs must remain stable across lots: solids equivalence, acid profile, sensory identity, moisture, and any carrier constraints. Treat your “fruit system” as a specified ingredient, not a generic commodity.

How to specify a high-acid concentrate for dry-format use
If a concentrate is intended for dry conversion or preblend use, your spec should include: °Brix/solids range, acidity parameters, sensory description, color expectations (when relevant), and any constraints related to downstream processing (e.g., “suitable for dry conversion” or “low sediment”). You should also define packaging format and storage requirements because concentrate quality can drift if stored improperly. If the concentrate will be converted to a powder, specify the solids equivalence and acceptance tests that ensure the powder delivers consistent sensory performance batch-to-batch.
