Fruit Pectin & Liquid Clarification Starts Here
High-performance pectinase for breaking down fruit pectin in liquid processing, improving clarity, filtration speed, and extraction efficiency.
Naturally occurring fruit pectin is a common bottleneck in commercial juice, wine must, and fruit extract production. It increases viscosity, traps solids, slows clarification, and clogs filtration equipment — all of which lead to longer processing times and lower yields. In high-throughput plants, the priority is not just understanding pectin chemistry, but removing it quickly and efficiently without compromising quality. Pectinase (Concentrate) from Aspergillus niger is engineered to meet this challenge. Combining polygalacturonase (EC 3.2.1.15) and pectin lyase (EC 4.2.2.10) activities, it depolymerises pectin molecules that bind water and cloud liquids. By reducing viscosity and freeing suspended solids, it accelerates depectinization and produces clearer liquid fractions across juice, must, berry maceration, citrus oil recovery, tropical fruit processing, and even specialty streams like coffee mucilage removal. For technical managers and procurement teams, the benefits are clear: this single enzyme input can shorten filtration cycles, improve pressing throughput, and maintain stable product clarity. Optimal working conditions are pH 3.0–5.0 and 40°C–55°C, with dosage tailored to fruit type, pectin load, and desired clarity. Precision dosing avoids overuse, helping plants control cost per batch while securing consistent performance. Whether handling apple pectin, citrus pectin, mixed berries, or tropical pulp, concentrated pectinase turns a slow, opaque process into a faster, more efficient one.
Apple Juice Clarification
Apple pectin is a major cause of haze, slow settling, and clogged filters in juice production. This pectinase breaks down fruit pectin in the mash or juice stream, improving press yield and reducing filtration time. Typical use is 50–200 PGAU/g of fruit solids, depending on pectin load, temperature, and residence time. The result is a cleaner liquid product with more consistent throughput.
Wine Must Depectinization
In grape must, pectin can trap solids and make pressing inefficient, especially in red wine processing. Controlled enzyme addition helps reduce viscosity, improve juice release, and support more efficient clarification. Working near pH 3.2–4.0 and 40°C–50°C, processors can improve separation without aggressive mechanical handling. This is a practical route to better liquid recovery and more predictable cellar performance.
Berry and Tropical Fruit Processing
Soft fruits such as raspberry, blueberry, mango, guava, and passion fruit often contain high levels of fruit pectin and fine suspended solids. Concentrated pectinase supports enzymatic maceration, increasing juice extraction while easing downstream clarification. Typical dosage is adjusted by fruit variety and pulp consistency, often 100–300 PGAU/g on a solids basis. This helps producers improve yield from difficult, high-pectin raw materials.
Citrus Oil and Peel Processing
Citrus pectin and peel cell-wall materials can restrict cold pressing and reduce essential oil recovery. Pectinase helps loosen the matrix surrounding oil glands, improving release of valuable liquid fractions from peel-based streams. Used at pH 3.0–4.5 and moderate temperatures, it supports better extraction efficiency while reducing the need for harsh mechanical action. That means more recoverable product and smoother processing.

Frequently Asked Questions
What is pectin, and why does it slow liquid processing?
Pectin is a natural polysaccharide found in fruit cell walls and pulp. In liquid processing, it increases viscosity, holds water, and keeps fine particles suspended. This leads to haze, slower settling, and clogged filters. In juice and wine plants, fruit pectin can reduce press efficiency and yield. Pectinase targets these structures by breaking them into smaller fragments, making liquids easier to clarify and separate.
How does pectinase work on fruit pectin in industrial systems?
Pectinase catalyses the hydrolysis and depolymerisation of pectin chains. It cuts the long molecular structures that create cloudiness and viscosity in fruit liquids. This formulation combines polygalacturonase and pectin lyase activity, suitable for depectinization in juice, must, and pulp streams. It performs best at pH 3.0–5.0 and 40°C–55°C, often added early in processing to improve extraction and prepare the liquid for clarification.
What dosage should we use for liquid fruit processing?
Dosage depends on pectin content, raw material maturity, temperature, pH, and desired clarity. Many systems use 50–300 PGAU/g of fruit solids or 20–150 ppm on a process basis, adjusting after pilot trials. High-pectin materials such as apple, citrus, and tropical fruit pulp may require higher rates. Aim for adequate contact to reduce pectin efficiently without excess cost. Plant trials are recommended before full-scale use.
Can this enzyme be applied in acidic fruit juices?
Yes. Pectinase from Aspergillus niger functions well under acidic conditions. Its optimal pH range is 3.0–5.0, covering most fruit juices including citrus, apple, and berry applications. This makes it suited to processes where maintaining acid profiles is important while still achieving rapid depectinization.
What are the storage and handling recommendations?
Liquid formulations should be refrigerated to maintain activity for up to 12 months. Powder forms can be stored for up to 24 months in cool, dry conditions away from moisture and sunlight. Secure packaging prevents contamination and ensures enzyme integrity during transit and storage.
