Rumen Bypass PUFA Powder Coating for Solvent-Free Milk Enrichment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for increasing polyunsaturated fatty acid content in ruminant milk, such as DHA and ARA, involve the use of expensive coating materials and organic solvents, leading to increased production costs and potential residues, while also failing to effectively enhance the conversion and accumulation of these fatty acids in milk.
Innovation Solution
A compound rumen bypass polyunsaturated fatty acid powder is prepared by mixing DHA and ARA oils with antioxidants, adsorbing them under vacuum, adding water-soluble antioxidants and enzymes, forming core pellets with an adhesive, and coating them with a rumen bypass coating to create a stable granule that is fed to ruminants, promoting the conversion and accumulation of these fatty acids in milk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If expensive coating materials such as food-grade whey powder and sodium caseinate are used for coating, then the rumen bypass effect is improved, but the production cost increases
Solution Approach 1:
The patent replaces expensive protein-based coating materials (whey powder, sodium caseinate) with inexpensive fat-based materials (animal fat powder, plant oil, monoglyceride, diglyceride). These cheaper materials achieve the same rumen bypass function through their resistance to rumen digestion, eliminating the need for costly protein coatings while maintaining effectiveness.
Solution Approach 2:
The patent changes the chemical composition parameters of the coating material from protein-based to fat-based substances. This parameter change fundamentally alters the coating's interaction with rumen enzymes, making it resistant to digestion while passing through to the small intestine, thereby achieving rumen bypass with cheaper materials.
2Ease of manufacture
If organic solvents such as ethanol are used to dissolve resin for coating, then the coating process is simplified, but organic solvent residues remain in the product
Solution Approach 1:
The patent removes organic solvents entirely from the coating process. Instead of dissolving resin in ethanol or other organic solvents, the invention uses fat-based materials that can be directly applied or dissolved in water, completely eliminating the harmful extraction step and the associated solvent residues.
Solution Approach 2:
The patent introduces water as a safe intermediary solvent instead of organic solvents like ethanol. Water serves as the medium for dissolving and applying the coating materials, achieving the same process functionality without introducing harmful residues into the final product.
3Quantity of substance
If polyunsaturated fatty acids are fed directly to ruminants, then the fatty acids are available for absorption, but they are degraded by rumen microorganisms
Solution Approach 1:
The patent segments the delivery system into two parts: a protected core containing the polyunsaturated fatty acids and an outer coating layer made of fat-based materials. This segmentation physically separates the fatty acids from rumen microorganisms, allowing them to pass through the rumen intact and be released in the small intestine where they can be absorbed without degradation.
Solution Approach 2:
The patent uses a nested structure where the polyunsaturated fatty acid core is embedded within the fat-based coating material. This nested design protects the inner fatty acids from rumen degradation while allowing the outer coating to interact with the rumen environment, achieving controlled release in the small intestine.

Function Achieved in This Case
The method effectively increases the DHA and ARA content in ruminant milk without using expensive materials or organic solvents, ensuring high conversion and accumulation, thereby supporting the industrialization of natural milk products rich in polyunsaturated fatty acids.
Implementation Method 1
spraying the mixed oil into an adsorbent under vacuum for adsorption

AI summary
A preparation of a high-conversion compound rumen bypass polyunsaturated fatty acid powder and the use thereof. The preparation comprises: adsorbing a polyunsaturated fatty acid oil by means of an adsorbent under vacuum conditions, and compounding a water-soluble antioxidant and an enzyme for promoting digestion and absorption to form a mixed powder; uniformly mixing and granulating the mixed powder by using a colloid or flour, and carrying out one-layer fixed coating by using a polysaccharide; and performing rumen bypass coating of the one-layer coating granule by using a fat powder or of a monoglyceride and a diglyceride by using a coating machine.
