Solution Overview

Problem

There is a need for clean label, cost-effective anti-caking agents for salt that are compatible with food products and do not cause undesirable changes in sensory characteristics, as conventional additives like tricalcium phosphate and sodium aluminosilicates are undesirable due to their chemical nature.

Innovation Solution

A blend of dry particulate flow agents such as flour, corn bran, soy fiber, inulin, whey, casein, starch, sugar, protein, lecithin, and citrus fiber is used to inhibit salt caking by simply dry-blending with sodium chloride or potassium chloride, providing effective caking resistance without the use of synthetic additives.

VSEngineering Contradiction Analysis

1Reliability

If conventional anti-caking additives like tricalcium phosphate and sodium aluminosilicates are used, then caking resistance is improved, but the clean label requirement and food compatibility are compromised

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces complex, expensive inorganic anti-caking agents with simple, inexpensive organic materials like sugars and starches that are already familiar and acceptable in food products. These natural materials provide the necessary anti-caking function without the negative sensory effects associated with conventional additives.

Inventive Principle:

2Reliability

If ferrocyanides are used as anti-caking agents, then crystal habit modification and caking inhibition are achieved, but the clean label acceptability deteriorates due to artificial and chemical nature

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces ferrocyanide chemicals with simple, naturally occurring organic materials such as sugars and starches. These materials are inexpensive, naturally derived, and already widely accepted in food products, thereby achieving caking inhibition without artificial additives.

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

Solution Approach 2:

The invention uses materials that naturally occur in food systems (sugars, starches) to replicate the anti-caking function previously achieved only by specialized chemical additives like ferrocyanides. This copying approach uses familiar food materials to perform the same protective function.
