Biogenic amine formation in fish roe in under the effect of drying methods and coating materials
The effects of drying methods (freeze‐drying, fluidized bed‐drying) and coating materials (gelatin, alginate, pectin) on the formation of biogenic amines (BAs) in fish roe were determined. The relationship between BAs content and free amino acid (FAA) profiles were monitored for 6 months. Lysine (28...

Zusammenfassung: | The effects of drying methods (freeze‐drying, fluidized bed‐drying) and coating materials (gelatin, alginate, pectin) on the formation of biogenic amines (BAs) in fish roe were determined. The relationship between BAs content and free amino acid (FAA) profiles were monitored for 6 months. Lysine (282.5–385.0 mg/kg), leucine (258.5–319.1 mg/kg), phenylalanine (211.9–316.0 mg/kg) and isoleucine (208.8–312.8 mg/kg) were the most abundant free essential amino acids, whereas aspartic acid (498.3–742.6 mg/kg) and glutamic acid (420.9–620.7 mg/kg) constitute a big amount of nonessential FAAs in dried roes. High amino acid content was obtained in gelatin coated samples. The main BAs were putrescine, spermine and spermidine and all increased significantly (p |
