Solution Overview

Problem

Existing methods for reducing oil and fat uptake in fried foods, such as those using cellulose ethers, require agglomeration steps or do not achieve sufficient oil reduction, posing health risks due to high fat content.

Innovation Solution

An edible composition comprising starch and cellulose ether particles with specific physical properties, such as a ratio of number volume mean to number surface area mean of not more than 200 micrometers and a volume fraction of fibrous particles of no more than 40%, is used to create a batter or food preparation that significantly reduces oil uptake when fried.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional cellulose ethers are used to reduce oil uptake, then oil reduction is achieved, but additional agglomeration steps are required

Engineering Contradiction:
Improveoil uptakeVSAvoidprocess complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The cellulose ether particles are pre-formed with optimized physical properties (M3.0/M2.0 ratio ≤ 200 μm and fibrous particle volume fraction ≤ 40%) before use in the batter. This preliminary preparation of the cellulose ether particles eliminates the need for additional agglomeration steps during the frying process, while still achieving effective oil uptake reduction of at least 15%.

Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The invention changes the physical parameters of the cellulose ether particles, specifically controlling the M3.0/M2.0 ratio to be ≤ 200 μm and the fibrous particle volume fraction to be ≤ 40%. These parameter changes optimize the particles' ability to reduce oil uptake, achieving at least 15% reduction and up to 25% reduction with most preferred particles, which is significantly better than conventional cellulose ethers.

AI summary

An edible composition comprising starch and cellulose ether particles, wherein the cellulose ether particles have a ratio M3.0/M2.0 of not more than 200 micrometers, wherein M3.0 is the number volume mean and M2.0 is the number surface area mean of the cellulose ether particles, and/or wherein the cellulose ether particles have a volume fraction of fibrous particles of no more than 40%, is useful for preparing a batter by mixing the edible composition with water. The batter is contacted with a food to prepare a battered food. The battered foods have a reduced oil and/or fat uptake when fried, as compared to fried non-battered food.
