Juice Processing Methods: A Guide for Food Ingredient Buyers

Commercial fruit juice is processed in three primary forms: not-from-concentrate (NFC), concentrate (FC), and puree. Each method involves different processing temperatures, Brix levels, storage formats, and cost structures. For food manufacturers sourcing juice ingredients, the processing method determines labelling requirements under EU Directive 2012/12/EU, flavour profile, nutritional retention, and logistics costs.

In short:

• NFC juice is pasteurised and packaged without any changes: what goes in is what comes out. This keeps the flavour fresh but makes it expensive to transport. Concentrate is made by evaporating the juice down to a thick syrup, shrinking the volume by 4–7 times. This makes it far cheaper to ship. At the factory, water is added back to turn it into juice again.
• Puree retains the whole fruit’s fibre and pulp, used in smoothies, baby food, and bakery fillings. Clarified juice has all pulp removed and is used for clear beverages and juice blends.
• EU Directive 2012/12/EU strictly defines “fruit juice” (100% juice, from concentrate or NFC), “nectar” (25–50% juice + water + sugar), and “juice drink” (less than 25% juice). Labelling must indicate “from concentrate” if applicable.

Juice Processing Methods Overview

Five processing methods account for virtually all juice traded in European food manufacturing. Each involves a different balance between flavour retention, shelf life, and cost.

The choice between NFC and concentrate is fundamentally an economic and quality decision. NFC has a premium price tag (typically 20–50% more expensive per equivalent litre of juice) but delivers superior flavour, which is why premium juice brands specify NFC on their labels. Concentrate is the standard for industrial beverage production, bakery, and food service applications.

Puree is often overlooked in these comparisons, but it is the format of choice for applications where fruit fibre and body are desirable: smoothie bases, baby food, bakery fillings, and fruit preparations for yoghurt. Unlike clarified juice or concentrate, puree retains the fruit’s pectin, fibre, and pulp, which contribute texture and mouthfeel. Mango, banana, and passion fruit are most commonly traded in puree form because their texture is a defining characteristic of the ingredient.

HPP (High Pressure Processing) is gaining ground as a cold pasteurisation alternative for premium NFC juices and smoothies. By subjecting the juice to 6,000 bar pressure, HPP achieves pathogen reduction comparable to thermal pasteurisation without the heat damage that degrades colour, vitamins, and fresh flavour. The technology is capital-intensive and the throughput is lower than conventional pasteurisation, but it provides a significant retail benefit and is now well-established in the European premium juice segment. For food manufacturers evaluating NFC suppliers, HPP-processed juice is worth considering for applications where the “fresh” claim and clean label positioning justify the cost.

How Does Concentrate Production Work?

Juice concentration removes water through vacuum evaporation at low temperatures (40–70°C under vacuum) to minimise heat damage. The juice is typically concentrated from its native Brix to 50–70°Bx depending on the fruit type. Orange juice concentrate, for example, is standardised at 65°Bx; apple juice concentrate at 70°Bx.

When juice is concentrated, much of the aroma evaporates along with the water. Some producers capture these aromas separately and add them back during reconstitution. This makes a noticeable difference in taste. Cheaper concentrates skip this step, which is why they often taste flat.

Reconstitution at the bottling plant involves adding water back to the concentrate to reach the original native Brix (e.g., 11.2°Bx for orange juice per Codex standard). EU regulation requires that reconstituted juice must be “organoleptic and analytically equivalent” to the juice before concentration.

The quality of essence recovery is one of the most overlooked factors in juice concentrate quality, and it has a direct impact on the taste of your finished product. Premium concentrate suppliers capture volatile aroma compounds during evaporation and add them back during reconstitution. Budget suppliers skip this step entirely, which is why some reconstituted juices taste flat or “cooked” compared to NFC. If you are evaluating concentrate suppliers, request samples both with and without essence add-back, the difference is immediately apparent in a sensory panel.

What Specifications Should You Check?

• Brix (°Bx): Measures the sugar content and is the most important specification. Each fruit has a standard range: orange: 10–13, apple: 11–14, mango: 14–18. For concentrates, Brix is listed at the concentrated level. Always check that the delivered Brix matches what you ordered.
• Ratio (Brix/acid): Measures the balance of sweetness to acidity. Critical for orange juice: the Codex minimum ratio is 7:1. Higher ratios indicate sweeter, riper fruit. Typical premium NFC orange ranges from 12:1 to 16:1.
• Total acidity: Expressed as citric acid equivalent (g/100mL). Affects flavour balance and preservative function. Specify the target range for your formulation.
• Colour: Measured by spectrophotometry or visual grading. Important for juice blends and beverages where consistent colour is a consumer expectation.
• Microbiological: Total plate count, yeast and mould, coliforms. Aseptic products should show very low counts. Frozen products may have slightly higher tolerances.
• Pesticide residues: EU MRLs apply. Particularly important for citrus juice (post-harvest fungicide residues) and tropical fruit purees.
• Authenticity markers: AIJN Code of Practice specifies reference values for isotope ratios, sugar profiles, and mineral content to detect adulteration (added sugar, dilution, wrong origin).

The AIJN Code of Practice is worth knowing about because it provides reference values for authentic juice composition: sugar profiles, isotope ratios, and mineral content for each fruit type. These reference ranges are the industry’s primary tool for detecting (added sugar, dilution with water, wrong geographic origin). If you suspect a supplier’s juice is not what it claims to be, AIJN reference testing at an accredited laboratory will confirm or disprove it.

For logistics planning: NFC juice requires continuous cold chain (–2°C to +4°C for chilled, −18°C for frozen NFC), which significantly increases transport and storage costs. Aseptic concentrate ships at ambient temperature, which is one of the key economic advantages beyond volume reduction. When comparing NFC and concentrate pricing, don't look at price per kilogram alone. NFC needs cold storage, which adds cost that isn't reflected in the headline price.

Frequently Asked Questions

What does “not from concentrate” mean?

NFC means the juice was squeezed from the fruit, pasteurised, and packaged as-is. No water was removed and no water was added back. It's the closest thing to fresh-squeezed juice in a commercial supply chain. The label "not from concentrate" exists specifically to distinguish it from juice that was first concentrated (water removed) and then reconstituted (water added back).

Can you label reconstituted concentrate as “juice”?

Yes, under EU Directive 2012/12/EU, reconstituted concentrate can be labelled “fruit juice” but must include the phrase “from concentrate” on the label. The reconstituted juice must be analytically and sensorially equivalent to the original juice before concentration.

What is the shelf life of aseptic juice concentrate?

Aseptic juice concentrate stored at ambient temperature (below 25°C) typically has a shelf life of 12–18 months. Frozen concentrate stored at −18°C can last 24+ months. NFC juice in aseptic packaging has 9–12 months shelf life; chilled NFC has 2–4 weeks.

What is essence recovery in juice processing?

When juice is concentrated, much of the aroma evaporates along with the water. Better producers capture these aromas separately and add them back during reconstitution. This makes a noticeable difference in taste. Cheaper concentrates skip this step, which is why they often taste flat.
