Authenticity of 100% Orange Juice in the Czech Market in the Years 1996 - 2001
Original language description
Commercial orange juices samples obtained from the Czech market have been analysed within the years 1996 - 2001. The quality and authenticity of samples was evaluated according to the Code of Practice of AIJN (the selected main analytical criteria were followed - K+, Na+, Ca2+, Mg2+, citric, isocitric and malic acid, citric acid/isocitric acid ratio, glucose, fructose, saccharose, sorbitol, formol number, flavonoid glycosides - according to Davis and HPLC procedure, refractive index and other). During the years the approach of producers to the quality and authenticity of juices has developed. The main problem: in the 1996 were: i) the lower fruit content in juice, ii) massive addition of sugars masked with addition of citric acid, iii) several examplesof "synthetic" orange juice were found. Within the subsequent years the authenticity slightly improved, the main problems in 2000/2001 the deviations were: i) lower refractive index, ii) pulp wash addition, iii) lower quality of water us
