Dual-Syrup Food Coating to Reduce Clumping at Lower Sugar

Solution Overview

Problem

Conventional methods for reducing sugar content in food product coatings, such as breakfast cereals, result in undesirable clumping, texture, and appearance issues, which affect consumer acceptance.

Innovation Solution

A dual-spray method applying a sucrose syrup and a non-sucrose carbohydrate syrup separately to food products, either simultaneously or sequentially, without active drying, to form a reduced sugar coating that mimics the appearance of traditional coatings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If sugar content in coating is reduced, then health benefits are improved, but clumping occurs and appearance deteriorates

Engineering Contradiction:

Improvesugar contentVSAvoidcoating uniformity

Core Design Contradiction:

Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The coating system is segmented into two separate syrup applications: a first syrup containing sucrose and a second syrup containing non-sucrose carbohydrates. This segmentation allows each syrup to be optimized independently for its specific function while together they achieve the desired low-sugar coating without clumping.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The coating uses a composite material system combining sucrose syrup and non-sucrose carbohydrate syrup in specific ratios (e.g., 1:1 to 3:1 by weight). This composite approach leverages the complementary properties of both syrup types to achieve both low sugar content and stable, non-clumping coating formation.

Inventive Principle:

Principle #40Composite materials

Solution Approach 1:

The coating system is segmented into two separate syrup applications: a first syrup containing sucrose and a second syrup containing non-sucrose carbohydrates. This segmentation allows each syrup to be optimized independently for its specific function while together they achieve the desired low-sugar coating without clumping.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent adjusts critical parameters including syrup temperatures (first syrup at higher temperature, second syrup at lower temperature), application rates (first syrup at 15-65% of food weight, second syrup at 15-65% of food weight), and the ratio of sucrose to non-sucrose syrups to optimize both appearance and low sugar content.

Inventive Principle:

3Device complexity

If single syrup application is used, then process simplicity is maintained, but clumping occurs

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSStability of the object's composition

Solution Approach 1:

The coating system is segmented into two separate syrup applications: a first syrup containing sucrose and a second syrup containing non-sucrose carbohydrates. This segmentation allows each syrup to be optimized independently for its specific function while together they achieve the desired low-sugar coating without clumping.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent maintains continuous coating action by applying the first syrup, then immediately applying the second syrup without interruption or active drying between applications. This continuous dual-syrup application prevents clumping while adding only minimal process complexity through the use of two applicators.

Inventive Principle:

AI summary

A system and method for applying a reduced sugar coating to a food product is provided. The system uses separate applications (simultaneous or sequential) of a non-sucrose carbohydrate syrup from a first applicator and a sucrose syrup from a second applicator. The dual applications of the syrups are applied without an active drying step between applications. The process results in a coated food product with reduced clumping and a desired crystallized appearance even with the reduced levels of sugar.
