Single-Pass First Break Wheat Milling Preserves Germ and Oil
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wheat milling processes separate and discard wheat germ, leading to a loss of essential nutrients and antioxidants, and the wheat germ oil becomes rancid due to exposure to air, resulting in refined white flour that lacks the nutritional benefits of wheat germ.
Innovation Solution
A method involving a single pass through corrugated first break rollers to produce first break wheat, maintaining wheat germ and wheat germ oil intact and surrounded by endosperm, preventing exposure to air and oxidation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional milling processes separate and discard wheat germ, then refined white flour is produced with longer shelf life, but nutritional value is significantly reduced
Solution Approach 1:
The invention extracts only the harmful element (oxygen exposure) from the system while retaining the beneficial components (wheat germ and oil). By removing air contact through vacuum sealing and inert atmosphere, the wheat germ is preserved without being separated or discarded, thus maintaining nutritional value while preventing rancidity
Solution Approach 2:
The patent creates an inert environment by using vacuum sealing and inert gas (nitrogen or carbon dioxide) to displace oxygen around the wheat germ. This inert atmosphere prevents oxidative rancidity of the wheat germ oil while allowing the complete wheat grain to be milled and processed, thereby preserving both shelf life and nutritional value
2Quantity of substance
If wheat germ is retained in milled wheat, then nutritional value is improved, but the wheat germ oil becomes rancid due to exposure to air
Solution Approach 1:
The patent applies inert atmosphere protection by sealing milled wheat containing wheat germ in vacuum packages or flushing with inert gases like nitrogen or carbon dioxide. This creates an oxygen-free environment that prevents oxidation of the wheat germ oil while allowing the wheat germ to remain intact in the milled product, thus improving nutritional value without causing rancidity
Solution Approach 2:
The invention removes the harmful oxygen from the system while retaining the wheat germ. By extracting only the oxygen through vacuum sealing and replacing it with inert atmosphere, the wheat germ and its nutritional components are preserved without exposure to the harmful oxidizing environment
3Manufacturing precision
If multiple break rollers are used to completely separate endosperm from wheat germ, then refined flour quality is improved, but processing time and complexity increase
Solution Approach 1:
The patent applies partial action by using only one or two break rollers instead of the traditional five or six roller mills. This partial milling approach is sufficient to achieve the desired flour quality while maintaining wheat germ integrity, thereby reducing processing time and equipment complexity without sacrificing manufacturing precision
Solution Approach 2:
The invention segments the milling process into a simplified sequence using fewer break rollers followed by conventional sifting. This segmentation allows the essential separation function to be achieved with reduced complexity, maintaining flour quality while eliminating unnecessary processing steps
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method preserves the nutritional value of wheat germ and endosperm, producing enriched bread and bakery products with improved consistency, flavor, and extended freshness without rancidity.
Implementation Method 1
milling wheat grains through first break rollers to obtain first break wheat
Implementation Method 2
maintaining the wheat germ intact, completely surrounded and protected by the endosperm, such that the wheat germ is not permitted to come into contact with air
Implementation Method 3
prevents the damaging effects of oxidation of the wheat germ and/or the wheat germ oil

AI summary
A method of producing first break wheat which maintains wheat germ and wheat germ oil intact and surrounded in a protected state by endosperm includes milling wheat grains via a single pass through corrugated first break rollers thereby forming an amount of first break wheat, wherein the corrugated first break rollers are specifically designed to maintain wheat germ and wheat germ oil in the first break wheat intact and surrounded in a protected state by endosperm, and eliminating further processing of the first break wheat which exposes the wheat germ and wheat germ oil therein to the surrounding atmosphere. A first break wheat mixture is obtained by mixing first break wheat with white flour to obtain a first break wheat mixture including about 3% to about 50% by weight of first break wheat and about 50% to about 97% by weight of white flour.
