Techniques for Probiotics Integration in Milk
Integrating viable probiotics into milk products presents significant technical hurdles, with survival rates often dropping below 106 CFU/g during processing and storage. Traditional incorporation methods expose probiotic strains to thermal stress during pasteurization (72-75°C), pH changes during fermentation (pH 4.0-4.5), and oxidative stress during storage, all of which can compromise bacterial viability.
The fundamental challenge lies in maintaining probiotic stability and functionality while preserving milk's nutritional properties and meeting food safety requirements.
This page brings together solutions from recent research—including milk fat globule membrane protection systems, synergistic oligosaccharide combinations, engineered acid-resistant strains, and lactose-deficient starter cultures. These and other approaches focus on enhancing probiotic survival rates while maintaining product quality throughout shelf life.
1. Probiotic and Oligosaccharide Composition with Bifidobacterial Strains and Human Milk Oligosaccharides
NV NUTRICIA, 2024
A synergistic probiotic and oligosaccharide combination for infant gut health, specifically targeting early life intestinal microbial dysbiosis. The composition comprises a unique blend of specific bifidobacterial species and human milk oligosaccharides (HMOs) that interact in a synergistic manner. The bifidobacterial strains, particularly B. bifidum and B. breve, possess extracellular enzymes that degrade specific HMOs, while B. breve strains with beta1,4-galactanase activity facilitate the degradation of galactose-containing HMOs. This combination enables enhanced fermentation and growth of the bifidobacterial strains, particularly in the presence of HMOs, while maintaining the beneficial properties of the oligosaccharides.

6. Fermented Milk Production Using Lactose-Deficient Streptococcus and Lactobacillus Strains for Enhanced Probiotic Viability
CHR HANSEN AS, 2021
A process for making fermented milk products with higher levels of probiotic bacteria like Bifidobacterium and Lactobacillus. The process involves using specific lactose-deficient strains of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus that can ferment non-lactose sugars like sucrose. These strains are added along with the probiotic bacteria to the milk base. This allows the probiotics to grow and survive better during fermentation by depleting the lactose faster and maintaining lower pH levels. The result is higher cell counts of probiotics like Bifidobacterium and Lactobacillus in the final fermented milk product.
7. Compositions Containing Milk Fat Globule Membrane for Probiotic Protection Against Bile-Induced Stress
MJN US HOLDINGS LLC, 2021
Compositions for preserving probiotic viability in the gut. The compositions contain milk fat globule membrane (MFGM) which helps protect probiotics from bile-induced stress and reduces bile-induced stress of probiotics. The MFGM also helps preserve probiotic viability in the presence of bile. The compositions can be used in infant formulas, follow-up formulas, young child milks, and other nutritional products to improve probiotic survival and effectiveness.
8. Food Surface Application of Milk-Derived Probiotic Cultures for High Water Activity Baked Goods
GOODMAN FIELDER PTE LTD, 2021
Probiotic-enriched foods like bread that contain live bacteria cultures derived entirely from milk components. The method involves applying a composition inoculated with probiotics onto the food surface. This milk-derived composition can be used to fortify foods like bread with viable probiotics even at high water activity levels above 0.5, which is challenging for traditional probiotic fortification methods. The milk-derived composition allows stable probiotic retention in foods like bread without altering taste or appearance. It enables commercial production of probiotic foods with therapeutic viable cell counts using only milk-based ingredients.

11. Fermented Dairy Production Method Utilizing Lactobacillus casei and Lactose Metabolism-Deficient Lactic Acid Bacteria
CHR HANSEN AS, 2018
Method for producing fermented dairy products using a combination of Lactobacillus casei and other lactic acid bacteria, with at least one of the other strains having lactose metabolism defects. The method involves adding the combination to milk, where the lactose metabolism-deficient bacteria can metabolize lactose and other carbohydrates present in milk, while the lactobacillus casei bacteria facilitate rapid growth and acidification. The combination of these two strains enables faster fermentation times compared to traditional Lactobacillus casei fermentation alone, while maintaining the characteristic lactic acid production.
12. Single-Step Fermentation Method Using Combined Lactic Acid and Bacillus Bacteria Cultures in Milk
