According to Gram Research analysis, adding chickpea flour to milk-based probiotic drinks significantly improves the survival and growth of beneficial bacteria. A 2026 laboratory study found that milk formulations containing 4.5 percent chickpea flour supported bacterial growth to 8 Log CFU/mL and maintained higher bacterial viability over 28 days of refrigerated storage compared to formulations without chickpea flour. The chickpea flour also increased healthy plant compounds called phenolics in the drinks.
Researchers discovered that adding chickpea flour to milk-based probiotic drinks helps beneficial bacteria survive much longer. In a 2026 study published in PLoS One, scientists tested two types of helpful bacteria called Lactobacillus plantarum in milk formulations with and without chickpea flour. The chickpea flour version showed stronger bacterial growth, better stability during storage, and increased healthy plant compounds called phenolics. This finding could lead to better probiotic products that keep beneficial bacteria alive longer, making them more effective for digestive health.
Key Statistics
A 2026 laboratory study published in PLoS One found that milk formulations with 4.5 percent chickpea flour showed a pH decrease of 1.81 to 1.38 units during fermentation, compared to only 0.58 to 0.52 units in formulations without chickpea flour.
Research shows that chickpea flour-enhanced probiotic formulations maintained bacterial viability at 8 Log CFU/mL throughout 28 days of cold storage, significantly higher than control formulations without the chickpea ingredient.
A 2026 study testing two strains of Lactobacillus plantarum found that adding chickpea flour increased total phenolic content in milk-based probiotic formulations while maintaining stable bacterial survival over the entire storage period.
The Quick Take
- What they studied: Whether adding chickpea flour to milk-based drinks containing helpful bacteria would keep those bacteria alive and healthy longer
- Who participated: This was a laboratory study testing four different milk formulations containing two strains of beneficial bacteria called Lactobacillus plantarum, with samples tested over 24 hours of fermentation and 28 days of refrigerated storage
- Key finding: Milk formulations containing chickpea flour kept the beneficial bacteria alive and thriving at higher levels (8 Log CFU/mL) compared to formulations without chickpea flour, while also increasing healthy plant compounds
- What it means for you: If these results hold up in human studies, probiotic milk drinks made with chickpea flour could deliver more live beneficial bacteria to your gut, potentially improving digestive health benefits. However, this is early laboratory research and more testing in people is needed before making dietary changes
The Research Details
Scientists created four different milk drink formulations in a laboratory setting. Each formulation contained 10 percent skimmed milk and 10 percent sugar as a base. Two formulations included one type of beneficial bacteria (Lactobacillus plantarum S180.7), and two included a different strain (Lactobacillus plantarum SBR64.7). Half of each pair contained 4.5 percent chickpea flour, while the other half did not. The researchers then measured how well the bacteria survived and grew during 24 hours of fermentation (the process where bacteria multiply) and during 28 days of storage in a refrigerator at 4 degrees Celsius (about 39 degrees Fahrenheit). They tested multiple factors including acidity levels, bacterial counts, and the presence of healthy plant compounds called phenolics.
This research approach is important because it tests whether a simple, natural ingredient like chickpea flour can improve the survival of probiotic bacteria in food products. Probiotics only work if the bacteria stay alive and active until you consume them. By testing the formulations over both short fermentation periods and long storage times, the researchers could see if chickpea flour helps bacteria survive the entire shelf life of a product. This type of laboratory testing is a necessary first step before testing in actual human subjects.
This study was published in PLoS One, a peer-reviewed scientific journal, which means other experts reviewed the work before publication. The research used standardized laboratory methods to measure bacterial survival and chemical composition. However, this is laboratory research only, not testing in humans or animals. The sample size for bacterial formulations was not explicitly stated, which limits our ability to assess statistical power. The findings are promising but represent early-stage research that would need follow-up studies in people to confirm real-world benefits
What the Results Show
Chickpea flour dramatically improved how acidic the milk formulations became during fermentation. Formulations with chickpea flour showed a pH drop of 1.81 to 1.38 units (meaning they became more acidic), while formulations without chickpea flour only dropped 0.58 to 0.52 units. This increased acidity is important because it indicates stronger bacterial activity and fermentation. More importantly, the chickpea flour formulations supported bacterial growth to 8 Log CFU/mL, which is a standard measurement of bacterial concentration. The bacteria remained stable and viable at higher levels throughout the entire 28-day storage period in the refrigerator compared to the control formulations without chickpea flour. This means the beneficial bacteria stayed alive and ready to work longer when chickpea flour was added.
The chickpea flour formulations also increased the total content of phenolics, which are plant compounds with antioxidant properties that may provide additional health benefits. Interestingly, while phenolic content increased, the overall antioxidant activity did not change significantly, suggesting that the quantity of these compounds increased but their effectiveness remained similar. Both bacterial strains tested (S180.7 and SBR64.7) showed improved survival with chickpea flour, indicating this benefit is not limited to just one type of bacteria. The formulations maintained their improved stability throughout the entire 28-day cold storage period, suggesting chickpea flour provides lasting protection for probiotic bacteria
This research builds on existing knowledge that certain plant-based ingredients can support probiotic bacteria survival. Previous studies have shown that various fibers and plant compounds can act as prebiotics, which are foods that help beneficial bacteria grow. This study specifically demonstrates that chickpea flour, an affordable and widely available ingredient, can serve this function in milk-based probiotic products. The findings align with growing research showing that combining probiotics with plant-based ingredients creates more stable and effective products. This work contributes to the emerging field of functional foods that combine multiple beneficial components
This study was conducted entirely in laboratory conditions, not in human bodies or even in animal models. The actual digestive environment is much more complex than a milk formulation in a refrigerator, so results may differ significantly when these products are consumed. The study did not measure whether the bacteria actually provided health benefits, only whether they survived better. The sample size and number of replicates were not clearly specified in the abstract. The research tested only two specific strains of Lactobacillus plantarum, so results may not apply to other probiotic bacteria. Additionally, the study did not test whether the chickpea flour itself might cause digestive issues or allergic reactions in sensitive individuals
The Bottom Line
Based on this laboratory research, chickpea flour appears to be a promising ingredient for improving probiotic product stability. However, confidence in real-world benefits is currently low because this is early-stage laboratory research. Do not change your diet based on this single study. If you are interested in probiotics, continue consuming established probiotic products and consult your doctor about whether they are appropriate for your health situation. Wait for human clinical trials before expecting significant health benefits from chickpea flour-enhanced probiotic products
Food manufacturers and probiotic product developers should pay attention to these findings as they develop new products. Researchers studying probiotics and functional foods should consider this work as a foundation for further investigation. People interested in digestive health and probiotics should be aware that better probiotic products may be coming, but should not expect immediate changes to existing products. People with chickpea allergies should avoid these products once they become available. People with digestive sensitivities should consult a healthcare provider before trying new probiotic formulations
This is laboratory research, so there is no timeline for personal health benefits yet. If manufacturers begin using chickpea flour in probiotic products, it could take 1 to 3 years for these products to reach store shelves. Human clinical trials to test actual health benefits would likely take 2 to 5 years to complete. Realistic expectations for seeing any digestive health benefits would be several months of consistent consumption, similar to other probiotic products, but this remains unproven for chickpea flour formulations
