Solution Overview

Problem

The mass production of glazed snack food products is hindered by the tendency for crystallization or sedimentation in glazes containing sugars, leading to equipment clogging and production delays, and existing glazes often include hydrocolloids and additives that cause precipitation, compromising visual appeal and shelf stability.

Innovation Solution

Aqueous sugar coating comprising at least 60% sugar, a juice concentrate, and lacking cornstarch, with a Brix value of 68° or greater and 16.5% reducing sugars, which is stable and free of solids, allowing continuous application and maintaining gloss and shine even after baking, while being free of hydrocolloids and additives that cause precipitation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a glaze containing sugars is used to achieve glossy appearance and flavor enhancement, then the visual appeal and taste of the snack food product are improved, but crystallization and sedimentation occur within the glaze during mass production, leading to equipment clogging and production delays

Engineering Contradiction:
Improveglossy appearanceVSAvoidmass production efficiency
Core Design Contradiction:
Illumination intensityVSProductivity

Solution Approach 1:

The patent applies parameter changes by modifying the chemical composition of the glaze - specifically using a high fructose corn syrup-based glaze with controlled water activity (0.70-0.85) and specific pH range (2.5-3.5). These parameter adjustments prevent sugar crystallization while maintaining gloss, enabling continuous mass production without equipment clogging.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses a composite glaze formulation combining high fructose corn syrup, cornstarch, and water in specific ratios. This composite material provides both the desired glossy appearance and resistance to crystallization, solving the contradiction between visual appeal and production efficiency.

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If hydrocolloids and additives are added to the glaze to prevent crystallization, then the stability of the glaze is improved, but precipitation of solids occurs within the liquid glaze, compromising visual appeal and shelf stability

Engineering Contradiction:
Improveglaze stabilityVSAvoidprecipitation of solids
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The patent controls water activity (0.70-0.85) and pH (2.5-3.5) parameters to achieve glaze stability without adding hydrocolloids. This parameter optimization prevents both crystallization and precipitation, maintaining clarity and shelf stability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention uses cornstarch, a simple and inexpensive material, instead of complex hydrocolloids or multiple additives. This simple approach provides sufficient stability while avoiding the precipitation problems associated with commercial additives.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Illumination intensity

If the glaze is applied to uncooked dough and then baked, then the flavor and visual appeal are enhanced, but the glaze may lose its gloss and shine after baking

Engineering Contradiction:
Improveshine and glossVSAvoidbaking temperature effect
Core Design Contradiction:
Illumination intensityVSTemperature

Solution Approach 1:

The patent formulates the glaze with specific water activity (0.70-0.85) and pH (2.5-3.5) ranges that are optimized to maintain gloss after baking. The high fructose corn syrup composition and controlled moisture content allow the glaze to withstand baking temperatures while retaining its shiny appearance.

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary

A sugar coating or glaze with reducing sugars greater than about 16.5% and a viscosity ranging between 170 and 650 cP is applied onto an uncooked dough product during a continuous process in the production of baked snack foods. The sugar coating has a pH of between about 1.7-3.3. The glaze maintains its form as a liquid free of solids at room temperatures despite the presence of sugars over 60% refined sugars. The glaze is applied onto a dough the glazed product is then baked, forming a glazed baked snack food product having at least 5% of a smooth, shiny glaze on a surface of the snack food product.
