Novel bacterial culture enriches yogurt with bioactive peptides for healthy ageing

Julie E. Dalziel, Paul Maclean, Evelyne Maes

As consumers demand more ‘natural’ minimally processed foods with health benefits, new knowledge on bioactive peptides produced through fermentation can be helpful for product design. The study examined whether the simple addition of a novel culture for co-fermentation during traditional yogurt making …

Influence of sugar composition in yoghurt on sweet receptor activation and sensory sweetness perception

Raise Ahmad, Amanda Dupas de Matos, Joanne Hort, Li Day et autres

Sweetness is sensed by sweet taste receptor heterodimer (TAS1R2/TAS1R3) which responds to sucrose, glucose, fructose, and galactose. Limiting added sugar in dairy foods while maintaining sweetness for palatability is important in healthy food design. We investigated the influence of sugar composition in …

Social Isolation Induces Sex‐Specific Differences in Behavior and Gut Microbiota Composition in Stress‐Sensitive Rats

Charlotte Hurst, Gosia Zobel, Wayne Young, T. A. Olson et autres

BACKGROUND: Social isolation (SI) is an established rat model of chronic stress. We applied this to the stress-sensitive Wistar Kyoto (WKY) strain to explore brain-to-gut interactions associated with mood. Whether SI stress-induced behavioral changes are sex-specific or if they affect the microbiome …

Peptide profiling to predict bitterness in fermented milk from different bacterial cultures and relationship with human bitter taste receptor activation

Evelyne Maes, Raise Ahmad, Charles A. Hefer, Stephen R. Haines et autres

Microbial fermentation is frequently used in the food industry to enhance organoleptic experience. In fermented milk and yogurt, peptides released from milk protein upon fermentation can contribute to a bitter taste in the final dairy product, depending on the lactic acid bacterial …

Peripherally Restricted Activation of Opioid Receptors Influences Anxiety-Related Behaviour and Alters Brain Gene Expression in a Sex-Specific Manner

Nabil Parkar, Wayne Young, T. A. Olson, Charlotte Hurst et autres

Although effects of stress-induced anxiety on the gastrointestinal tract and enteric nervous system (ENS) are well studied, how ENS dysfunction impacts behaviour is not well understood. We investigated whether ENS modulation alters anxiety-related behaviour in rats. We used loperamide, a potent μ-opioid …

Novel insights into mechanisms of inhibition of colonic motility by loperamide

Nabil Parkar, Nick J. Spencer, T. A. Olson, Wayne Young et autres

Background: It is well known that opiates slow gastrointestinal (GI) transit, via suppression of enteric cholinergic neurotransmission throughout the GI tract, particularly the large intestine where constipation is commonly induced. It is not clear whether there is uniform suppression of enteric neurotransmission …

Anxiety-like Behavior in Female Sprague Dawley Rats Associated with Cecal Clostridiales

Tracey Bear, Nicole C. Roy, Julie E. Dalziel, Christine A. Butts et autres

The relationship between the microbiota profile and exposure to stress is not well understood. Therefore, we used a rat model of unpredictable chronic mild stress (UCMS) to investigate this relationship. Depressive-like behaviors were measured in Female Sprague Dawley rats using the sucrose …

A Diet Enriched with Lacticaseibacillus rhamnosus HN001 and Milk Fat Globule Membrane Alters the Gut Microbiota and Decreases Amygdala GABA a Receptor Expression in Stress-Sensitive Rats

Julie E. Dalziel, Gosia Zobel, Hilary Dewhurst, Charlotte Hurst et autres

Brain signalling pathways involved in subclinical anxiety and depressed mood can be modulated via the gut brain axis (GBA), providing the potential for diet and dietary components to affect mood. We investigated behavioural, physiological and gut microbiome responses to the Lacticaseibacillus rhamnosus …
