Abstract In order to establish an efficient detection method to evaluate the formation of Amadori compounds (ACs) in food products and study the potential health effects an ultra‐high performance liquid chromatography‐tandem mass spectrometric (UPLC‐MS/MS) method using caffeine as internal standard was developed to determine eight ACs

Formation of Amadori Compounds in Dehydrated

2019-5-25The presence of Amadori compounds in commercial dehydrated fruits has been shown through HPLC analysis of the corresponding 2-furoylmethyl-amino acids obtained by acid hydrolysis Furosine (2-furoylmethyl-lysine) was the main 2-furoylmethyl derivative observed in dried figs and apricot samples whereas in prunes and dates similar amounts of furosine and 2-furoylmethyl-γ-aminobutyric

Quality of Dried Foods

Fruits can be sun dried dehydrated or processed by a combination of the two Sun drying causes losses in carotene content Dehydration especially spray drying can be accomplished with loss in this nutrient Vitamin C is lost in great proportions in sun-dried fruits Freeze- drying of fruits retains greater portions of vitamin C and other

Browning Reaction

The Maillard reaction is responsible for literally hundreds of flavor compounds and is even used by flavor chemists to create artificial flavors The Maillard reaction is a chemical reaction between a reducing sugar and the free amino group of an amino acid or a protein The rate of the Maillard Page 2 of 12

Heterocyclic compounds are strongly related to roast meat flavour formation during heating and are important compounds in food processing and flavouring They have been observed in reaction mixtures of amino acids and sugars but some can also be formed from lipids (Whitfield 1992 )

Ruminant meat flavor influenced by different factors

2018-9-24Ruminant meat flavor is an important quality and sensory parameter which relays mainly on the organoleptic characteristics of meat Meat flavor is vital factor for the palatability and acceptability of meat by the consumers There are various intrinsic and extrinsic factors that influence eating quality of meat Among these factors flavor is the major contributor
