Abstract

Kefir is a homemade viscous and slightly effervescent beverage obtained by milk fermentation with kefir grains, which are built up by a complex community of lactic acid and acetic acid bacteria and yeasts confined in a matrix of proteins and polysaccharides. The present review summarizes the role of kefir micro-organisms in grain assembly and in the beneficial properties attributed to kefir. The use of both culture-dependent and independent methods has made possible to determine the micro-organisms that constitute this ecosystem. Kefir consumption has been associated with a wide range of functional and probiotic properties that could be attributed to the micro-organisms present in kefir and/or to the metabolites synthetized by them during milk fermentation. In this context, the role of micro-organisms in kefir health promoting properties is discussed with particular attention to the contribution of yeast as well as bioactive metabolites such as lactic and acetic acid, exopolysaccharides and bioactive peptides. Even though many advances on the knowledge of this ancient fermented milk have been made, further studies are necessary to elucidate the complex nature of the kefir ecosystem.

  • Kefir is a low-cost food, accessible to the general population, easy to handle, and with great functional potential due to its bioactive compounds like exopolysaccharides, conjugated fatty acids and peptidases.

    “It is a low-cost food, accessible to the general population, easy to handle and with great functional potential (18) due to its bioactive compounds (11, 18) like exopolysaccharides, conjugated fatty acids and peptidases (11, 16).”

    From Kefir and Intestinal Microbiota Modulation: Implications in Human Health (2021) · cites this paper as [16]

    The Health promoting properties section describes kefir’s functional and probiotic properties and attributes potential benefits partly to metabolites in the fermented milk. The Abstract describes homemade production and reuse of kefir grains, but the paper does not establish that kefir is low-cost, accessible to the general population, or easy to handle. The specific compound list is cited to other sources in the citing sentence. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Kefir is a fermented product formed by a single culture composed of lactic and acetic acid bacteria and yeast.

    “Kefir is a fermented product (11, 16) formed by a single culture composed of lactic and acetic acid bacteria and yeast (17).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
