Microbial Vitality of Probiotic Milks Supplemented With Cereal or Pseudocereal Grain Flours
Bibliographic record
Abstract
<p>Probiotic products containing <em>Lactobacillus rhamnosus</em> GR-1 have been shown to help decrease the risk of urogenital infections, delay the decline of CD4 lymphocytes in patients with human immunodeficiency virus, and survive in the intestinal tract without stimulating immune or inflammatory responses. Cereal and pseudocereal grains can act as prebiotic agents and could be an economical way of improving the nutritional value, functional qualities, and overall health benefits of probiotic products. The purpose of this study was to measure the growth and survival of <em>L. rhamnosus</em> GR-1 in fermented probiotic skim milk supplemented with a grain flour over a 28-day storage period. The objective was to determine if supplementation of the grain flours would have a positive effect on the microbial vitality of <em>L. rhamnosus</em> GR-1 in the final product and during storage. Five probiotic skim milk samples supplemented with a grain flour were prepared: oat (3% weight to volume ratio), lentil (3% w/v), rice (3% w/v), barley (3% w/v), and quinoa (3% w/v) along with one control probiotic skim milk sample. Results showed that the oat, rice, barley and quinoa flours supported the growth of <em>L. rhamnosus</em> GR-1 at viable levels (10<sup>8</sup>CFU/mL) during the first 14 days of storage; however, only skim milk supplemented with rice flour sustained the growth over the 28-day storage period. Future studies should conduct a sensory evaluation of this fermented probiotic rice flour milk as well as study rice milk inoculated with probiotics to produce a dairy-free and possible gluten-free product.</p>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
