Abstract

Aromatic coconut water (ACW) is a healthy drink with a unique aroma and high nutritional value. To better preserve ACW, exploring an efficient sterilization technique with good sterilization effects and fragrance retention effects is necessary. Pasteurization (PS) and cold plasma (CP) have been shown to be good sterilization techniques for effectively killing microorganisms in coconut water. However, there are few reports on the effects of PS and CP on the metabolites and flavor quality of ACW. This study systematically investigated the effects of CP and PS treatments on flavor compounds and primary metabolites of ACW using an integrated flavoromics and metabolomics approach. The results showed that compared with PS, CP had a less damaging effect on 2‐AP and better retention of key flavors in fresh ACW. In addition, dimethyl trisulfide was produced in pasteurized ACW and became the key active flavor compound, promoting off‐flavor formation. The results of the metabolomics analysis revealed that CP affected mainly amino acids and lipids and that PS affected mainly amino acids in the ACW. The results of the correlation analysis revealed that the sterilization process may modulate or modify the flavor of ACW by affecting these metabolites. This study offers a theoretical foundation for optimizing sterilization methods and regulating flavor quality in ACW and supports the potential application of CP technology in ACW preservation.

  • Cold plasma treatment could effectively maintain and enhance the aroma of coconut water, and treated coconut water retained key aroma compounds and increased creaminess and popcorn flavor.

    “It was found that cold plasma treatment could effectively maintain and enhance the aroma of coconut water, and the treated coconut water retained key aroma compounds and increased the creaminess and popcorn flavor of coconut water [20,21].”

    From Effect of Atmospheric Cold Plasma Treatment on the Microorganism Growth, Diversity, and Quality of Coconut Water During Refrigerator Storage (2025) · cites this paper as [21]

    Section 3.2.3 (page not provided) reports that cold plasma retained the key aroma compound 2-AP better than pasteurization and may increase freshness and fruity aroma. But it also reports that cold plasma reduced 2-AP relative to untreated coconut water, potentially reducing popcorn and butterscotch flavors. It does not support an increase in creaminess or popcorn flavor. (LLM, conf=0.90)

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.
