February 10/Ramat Yishay, Israel/Food Weekly Focus -- "The authenticity of fruit flavors in foods and beverages is of great importance for the producers of jams, ice creams, soft drinks, yogurt, etc. Regulations regarding the authenticity of flavors in foods and beverages will help consumers choose the foods best suitable for them," scientists in Israel assert.
"In order to enhance this goal, we have used headspace-solid phase microextraction stereoselective gas chromatography-mass spectrometry (HS-SPME stereoselective GC-MS) to determine the enantiomeric ratios of chiral flavor and fragrance indicators present in the raw materials and in the products: gamma-Decalactone in peach, nectarine, strawberry, passion fruit and apricot, as well as (E)-alpha-ionone in raspberry and linalool and linalyl acetate in bergamot, were used as indicators in stereoselective analysis of commercial foods and beverages.
