Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for milk curdling in cheese and dairy products, such as enzyme-based rennet and acid treatments, are costly, affect flavor, and introduce unwanted tastes or textures, while inorganic salts have health drawbacks and reduce pH, necessitating a cost-effective, organic, and flavor-preserving alternative.

Innovation Solution

A natural curdling ingredient synthesized through microbial fermentation of non-edible organic carbohydrates using a bacterial consortium of Lactobacillus spp., specifically Lactobacillus delbrueckii NCIM 2365 and Lactobacillus acidophilus NCIM 2285, producing lactates, acetates, and propionates fortified with calcium, which enhances taste and texture without reducing pH or increasing acidity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rennet (enzyme from ruminant stomach) is used for curdling, then coagulation effectiveness is improved, but cost increases and storage stability deteriorates

Engineering Contradiction:

Improvecoagulation effectivenessVSAvoidcost and storage stability

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces expensive, storage-sensitive rennet with a cost-effective microbial fermentation product that is more stable and easier to manufacture. The fermented organic acid product from Lactobacillus can be produced cheaply and stored without the critical stability issues of protein-based rennet.

2Reliability

If inorganic salts (sodium chloride, calcium chloride) are used for curdling, then coagulation is achieved, but health safety deteriorates and taste is affected

Engineering Contradiction:

Improvecoagulation capabilityVSAvoidhealth safety and taste quality

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical nature of the curdling agent from inorganic salts to organic acids produced by microbial fermentation. This parameter change transforms the curdling mechanism while eliminating the harmful health effects and off-flavors associated with inorganic salt addition.

3Reliability

If acid sources (lemon juice, vinegar) are used for curdling, then pH reduction achieves coagulation, but off-flavor is introduced

Engineering Contradiction:

Improvecoagulation efficiencyVSAvoidacidic off-flavor

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent uses a specific microbial strain (Lactobacillus) that produces organic acids as a byproduct of fermentation. This approach achieves the desired pH reduction and coagulation effect without the strong acidic off-flavors of conventional acid sources like lemon juice or vinegar.

Inventive Principle:

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent optimizes the concentration and type of organic acid produced by controlled microbial fermentation. This parameter optimization enables faster coagulation kinetics, reducing preparation time while maintaining effective curdling.

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 microbial fermentation-derived curdling ingredient reduces preparation time, improves flavor and texture, and provides nutritional calcium enrichment, offering a cost-effective alternative to traditional methods with minimal pH change and no off-flavors.

Implementation Method 1

carbohydrate sources obtained from non-edible grade organic cassava or wheat or maize are fermented using a microbial consortium of Lactobacillus spp

Methodology Applied

Scientific EffectFermentation: Fermentation

Implementation Method 2

The basic principle behind the curdling by this approach is the reduction of the pH i.e., development of the acidic condition in the milk. Proteins like casein in the milk are naturally available in the colloidal state in neutralized condition. Once the acid source is added to the milk, neutralized proteins will be disturbed and attracted to each other. This leads to the development of clumps commonly known as curds

Methodology Applied

Scientific EffectCoagulation: Coagulation

AI summary

In cheese production bacterial cultures secrets lactic acid and lowers the pH for promoting the curdling. However, longer incubation will increase the acidic condition followed by off flavor. “An Organic Natural curdling Ingredient” is produced by microbial fermentation of glucose obtained from the non-edible grain starches. The “microbial source” used is a consortium of two Lactobacillus sp. strains modified by way of strain improvement for product yield enhancement. Addition of 0.5 to 1% of this product reduces the incubation time and the acidic conditions. The major ingredient in “An Organic Natural curdling Ingredient” is a combination of naturally produced organic acids with mineral nutrient like calcium. The product has taste and texture improving efficiency by reducing the acidic flavor. Calcium is a valuable addition to the final product with high nutritional benefit in bio-available form.
