Enzymatic Pomace Treatment for Beverage Viscosity Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage products containing high-fiber fruit and vegetable materials face challenges in reducing viscosity while maintaining fiber content and consumer acceptability, as current methods like chemical hydrolysis and mechanical technologies either alter fiber structure or fail to break down fibers effectively, leading to undesirable textures and flavors.
Innovation Solution
The development of a low viscosity beverage product using enzymatically-treated pomace, where pomace is treated with enzymes like pectinase, cellulase, or hemicellulase to reduce fiber chain length without fiber loss, and then incorporated into a beverage at 25-40% concentration, achieving a viscosity of 700-1800 cP, thereby maintaining fiber content and improving consumer acceptance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high fiber fruit and vegetable materials are incorporated into beverages, then fiber content and nutritional value are improved, but viscosity increases leading to undesirable thick, fibrous textures
Solution Approach 1:
The patent applies enzymatic treatment to segment and break down the fibrous structure of pomace into smaller particles. This segmentation reduces the fiber chain length and molecular weight while maintaining fiber content, thereby decreasing viscosity and improving beverage flow properties without sacrificing nutritional value.
Solution Approach 2:
The patent changes the physical and chemical parameters of the pomace through enzymatic treatment, specifically reducing particle size, fiber chain length, and molecular weight. These parameter changes allow the beverage to maintain high fiber content while achieving desirable viscosity levels and mouthfeel characteristics.
2Ease of operation
If chemical hydrolysis is used to reduce viscosity, then viscosity is reduced, but fiber and sugar identities are not retained and chemicals are introduced
Solution Approach 1:
The patent uses food-grade enzymes as intermediaries to catalyze the breakdown of fibrous materials. These enzymes selectively target fiber structures without degrading sugars or introducing harmful chemical residues, providing a safe and effective method to reduce viscosity while preserving the integrity of nutritional components.
Solution Approach 2:
The patent replaces chemical hydrolysis methods with enzymatic hydrolysis. This substitution eliminates the need for harsh chemicals like formic acid and hydrochloric acid, avoiding non-specific reactions that degrade fiber and sugar identities, while achieving the same viscosity reduction through biocatalysis.
3Ease of operation
If mechanical technologies like homogenization and micronization are used, then fiber is pulverized, but chain length remains intact and viscosity reduction is insufficient
Solution Approach 1:
The patent replaces mechanical size reduction methods with enzymatic degradation. While mechanical methods only reduce particle size without affecting chain length, enzymatic treatment specifically targets and breaks down the polymer chains of fiber, achieving both particle size reduction and chain length reduction for effective viscosity control.
4Quantity of substance
If large pieces of insoluble fibers are incorporated into juice, then fiber content is increased, but undesired color, flavor, and fibrous textures are introduced
Solution Approach 1:
The patent segments large fibrous pieces into fine particles through enzymatic treatment. This segmentation eliminatesundesired fibrous textures and improves color and flavor by distributing fiber uniformly throughout the beverage, while maintaining the nutritional fiber content.
Solution Approach 2:
The patent changes the physical parameters of fiber particles through enzymatic treatment, reducing particle size, chain length, and molecular weight. These parameter changes transform the sensory properties of the beverage, eliminatingundesired textures while preserving fiber content.

Implementation Method 1
The enzymatically-treated pomace is obtained by treating the pomace with enzymes
Implementation Method 2
pomace is treated with enzymes like pectinase, cellulase, or hemicellulase to reduce fiber chain length

AI summary
A method for enzymatically treating pomace involves subjecting pomace to at least one enzyme in an amount between 0.15-1.0 wt% of the pomace. The pomace-enzyme mixture is heated to 25-57°C for 10-60 minutes before the at least one enzyme is deactivated to form the enzymatically-treated pomace. Thereafter, the enzymatically-treated pomace may be added to food and beverage products.
