Probiotic Dessert: Good for Your Gut & Stays Fresh?

study PMID: 40685452

Quick Summary: Researchers made a dairy dessert with a probiotic called Lactobacillus plantarum and a compound from algae. They found the dessert stayed fresh and kept its probiotic benefits for up to two months in the fridge!

What The Research Found

This study looked at a special dairy dessert. It contained a probiotic bacteria called Lactobacillus plantarum and a compound called phycoerythrin (PE) from algae. The researchers found that the dessert kept its probiotic power and the PE stayed stable for 60 days (about two months) when stored in the refrigerator. People also liked the taste!

Study Details

Who was studied: The study tested the dessert itself, not people. They looked at how the probiotic and PE held up over time.

How long: The dessert was stored and tested for 60 days (2 months).

What they took: The dessert contained Lactobacillus plantarum and PE.

What This Means For You

Probiotic Powerhouse: This research suggests that a dessert containing Lactobacillus plantarum could be a tasty way to get probiotics, which are good for your gut health.

Long-Lasting Freshness: The fact that the dessert stayed fresh for two months in the fridge is great news. It means you could buy it and have it on hand for a while.

Natural Ingredients: The study used a compound from algae, which is a natural ingredient. This could mean a healthier dessert option compared to those with artificial colors and preservatives.

Study Limitations

Not Tested on People: This study was done in a lab, not on people. We don't know for sure if the same benefits would happen in your body.

More Research Needed: We need more studies to confirm these findings and see how the dessert affects people's health.

Exact Amounts Unknown: The exact amount of PE in the dessert wasn't specified.

Key Findings

This 2025 in vitro study demonstrated that a semi-prepared dairy dessert fortified with 1% Lactobacillus plantarum and phycoerythrin (PE) nano-emulsion maintained probiotic viability above 10⁷ CFU/g (the threshold for therapeutic efficacy) and preserved PE stability (85% retention at room temperature for 72 hours) over 60 days of refrigeration (4°C). Sensory evaluations showed high acceptability scores (>4.5/5), suggesting potential for commercial development. Refrigeration slowed PE degradation and probiotic decline compared to room temperature storage.

Study Design

The study was an experimental in vitro trial conducted in 2025. It involved:
1. Extraction of PE from Nostoc sp. cyanobacteria.
2. Formulation of dairy desserts with PE nano-emulsion and 1% L. plantarum.
3. Stability testing of PE (72 hours at room temperature) and probiotic viability/sensory attributes over 60 days at 4°C.
No sample size or demographic data were provided, as the study focused on physicochemical and microbial analyses rather than human trials.

Dosage & Administration

Dosage:
L. plantarum: 1% (v/v) inoculum added to dairy dessert base.
PE: Concentration unspecified, but nano-emulsified to enhance stability.
Administration: Refrigerated (4°C) dairy dessert stored for 60 days. PE stability was tested in isolation and within the dessert matrix.

Results & Efficacy

PE Stability: Retained 85% of its activity at room temperature for 72 hours (p<0.05 vs. control).
Probiotic Viability:
Dessert stored at 4°C maintained >10⁷ CFU/g L. plantarum for 60 days (p<0.05 vs. room temperature groups).
Refrigeration reduced microbial decline by 0.5 log CFU/g compared to non-refrigerated samples.
Sensory Scores: Dessert received >4.5/5 for taste, texture, and appearance, indicating consumer acceptability.

Limitations

Sample Size: Methodology details (e.g., number of replicates) were omitted, limiting reproducibility.
In Vitro Design: Findings may not translate to in vivo efficacy or safety; human trials are needed.
PE Dosage: The exact concentration of PE in the dessert was not quantified, hindering dose-response analysis.
Short-Term Focus: Effects beyond 60 days or under varying storage conditions (e.g., temperature fluctuations) remain unknown.

Clinical Relevance

This study suggests refrigerated dairy desserts containing L. plantarum and PE nano-emulsion could serve as functional foods, preserving probiotic viability and bioactive stability for 60 days. For supplement users, it highlights a potential vehicle for delivering probiotics and algae-derived antioxidants without artificial preservatives. However, the lack of human data means clinical benefits (e.g., gut health, antioxidant effects) are speculative. Further research is needed to validate these results in vivo and assess long-term storage impacts.
