02 Jul 2021 --- A study from the Kirin Central Research Institute has demonstrated that milk-derived beta-lactopeptides improve cerebral blood flow (CBF) in the prefrontal cortex, which normally declines with age. “Beta-lactolin is an ingredient found in Camembert cheese. The milk-derived substance was discovered as a result of collaboration between Kyowa Kirin and Koiwai Dairy Products Company in Kirin Holdings’ brain science research,” Chisato Kubo, assistant manager of corporate communication at Kirin Holdings, tells NutritionInsight.
