  2. Free and Total Sulphur Dioxide
    While naturally present in wine, sulphur dioxide (SO2) can also be added to wine during the pre bottling stage of production to preserve products during storage. Sulphur dioxide is subject to legal limits and requires specific mention on labels where levels exceed 10 mg/L
  3. Alcoholic Strength by Volume
    Fera’s food authenticity team can analyse alcoholic beverages to determine their alcoholic strength by volume, expressed as ‘% vol’ on product labels. This analysis can suit both beverages producers and retailers wishing to verify labelling claims.
  4. Sugars: Fructose / Glucose / Sucrose
    This test will analyse your honey, drink or juice samples for total sugar content.
  5. 3-MPD & Cyclic Diglycerols
    Fera’s leading food authenticity scientists can analyse your samples for the presence of methoxy-1,2-propanediol (3-MPD) and cyclic diglycerols (CycDs), which are an indicator of potential adulteration of wine with synthetic glycerol.
  6. Preservatives (Citric, Sorbic, and Benzoic Acid)
