New insights of the application of water or ethanol-water plant extract rich in active compounds in food

Open access

Abstract

Plants are recognized as natural sources of antioxidants (e.g., polyphenols, flavonoids, vitamins, and other active compounds) that can be extracted by green solvents like water, ethanol, or their binary mixtures. Plant extracts are becoming more used as food additives in various food systems due to their antioxidant abilities. Their application in food increases the shelf life of products by preventing undesirable changes in nutritional and sensory properties, such as the formation off-flavors in lipid-rich food. This review summarizes the most recent literature about water or ethanol-water plant extracts used as flavors, colorings, and preservatives to fortify food and beverages. This study is performed with particular attention to describing the benefits of plant extract-fortified products such as meat, vegetable oils, biscuits, pastries, some beverages, yogurt, cheese, and other dairy products. Antioxidant-rich plant extracts can positively affect food safety by partially or fully replacing synthetic antioxidants, which have lately been linked to safety and health issues such as toxicological and carcinogenic consequences. On the other hand, the limitations and challenges of using the extract in food should be considered, like stability, level of purity, compatibility with matrix, price, sensory aspects like distinct taste, and others. In the future, continuous development and a tendency to use these natural extracts as food ingredients are expected, as indicated by the number of published works in this area, particularly in the past decade.

  • Previous research indicated that the higher polarity of water compared to ethanol allows for more efficient extraction of bioactive compounds, especially those that are more soluble in aqueous environments.

    “Previous research has indicated that the higher polarity of water compared to ethanol allows for more efficient extraction of bioactive compounds, especially those that are more soluble in aqueous environments [52].”

    From Comparative Analysis of Infusions and Ethanolic Extracts of Annona muricata Leaves from Colima, Mexico: Phytochemical Profile and Antioxidant Activity (2024) · cites this paper as [52]

    The Introduction says water efficiently extracts polar molecules and that extraction depends on compounds’ polarity and solubility. It does not establish that water is generally more efficient than ethanol for bioactive compounds; it notes that some compounds extract better with organic solvents or water–ethanol mixtures.

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.
