Solution Overview
Problem
Existing bread-making methods face challenges such as the need for chemical additives, long rising times, variability in product quality, and unpleasant odors, which hinder industrial application and consumer perception of authenticity and healthiness.
Innovation Solution
A processing aid comprising lactic acid bacteria and enzymes, specifically Lactobacillus Sanfranciscensis, Lactobacillus Rossiae, and Lactobacillus Plantarum, along with xylanase, is used to create natural emulsifiers through glycerol and fatty acid esterification, mimicking sourdough characteristics while using the straight dough method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sourdough method is used, then authenticity and healthiness are improved, but rising time and labor requirement increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-culturing specific lactic acid bacteria strains (Lactobacillus sanfranciscensis, Lactobacillus rossiae, Lactobacillus plantarum) and preparing enzyme blends before dough production. This allows the bacteria and enzymes to be ready to act immediately when added to the straight dough method, providing sourdough-like benefits without the extended spontaneous fermentation time.
Solution Approach 2:
The patent changes key parameters by selecting specific bacterial strains with optimized characteristics and controlling their concentration (e.g., 1x10^9 CFU/g after 72 hours fermentation). It also controls pH levels (maintaining above 4.0 to avoid gluten weakening) and uses enzyme blends with specific activities to achieve sourdough effects in a straight dough framework, thus reducing time while maintaining authenticity.
2Productivity
If chemical additives (E471, E472) are used, then dough stability and productivity are improved, but product safety and consumer acceptance worsen
Solution Approach 1:
The patent applies self-service by enabling the dough system to produce its own emulsifiers through the metabolic activity of lactic acid bacteria. The bacteria naturally produce glycerol and fatty acids that form emulsifying substances, eliminating the need for external chemical additives like E471 and E472 while maintaining dough stability and productivity.
Solution Approach 2:
The patent uses lactic acid bacteria as intermediary organisms that mediate between the raw ingredients and the final dough properties. These bacteria transform simple substrates into complex emulsifying substances through their metabolic processes, providing a natural bridge that achieves chemical additive effects without using harmful substances.
3Productivity
If high acidity sourdough is used, then fermentation activity is improved, but gluten strength and product quality worsen
Solution Approach 1:
The patent carefully controls the pH parameter to remain above 4.0, preventing the excessive acidification that weakens gluten. It achieves this by selecting bacterial strains with moderate acid production characteristics and controlling fermentation conditions, thus maintaining both fermentation activity and gluten strength.
Solution Approach 2:
The patent uses a composite approach by combining multiple lactic acid bacteria strains with different metabolic characteristics and adding enzyme blends. This composite system produces a balanced fermentation profile that generates sufficient acidity for activity without exceeding the threshold that damages gluten structure.
4Productivity
If straight dough method is used, then productivity and standardization are improved, but organoleptic properties and authenticity worsen
Solution Approach 1:
The patent applies preliminary action by pre-preparing active cultures of specific lactic acid bacteria and enzyme blends before dough mixing. This allows the straight dough method to immediately benefit from sourdough-like fermentation activity and flavor development, improving organoleptic properties without sacrificing production speed.
Solution Approach 2:
The patent introduces lactic acid bacteria and enzymes as intermediary agents that mediate between the simple straight dough process and complex sourdough-like outcomes. These intermediaries provide the biochemical activities needed for authentic flavor and texture while maintaining the efficiency of the straight dough method.

AI summary
The invention is a process for the formation of natural emulsifiers, characterized in that it comprises the use of brewer's yeast or Saccharomyces cerevisiae, the metabolism of which produces glycerol, heterofermentative lactic acid bacteria, which produce lactic acid, enzymes accessible to lactic acid bacteria for the formation of lactic acid, and wherein the esterification process between glycerol and lactic acid or acetic acid, or both, leads to the formation of emulsifier molecules.
