Two parameters not considered as paradigms for quality control of natural fruit juice in the Peruvian Technical Norms are studied here. These parameters a) free amino acid index (FAI) and b) ceIlular structures (CE), would contribute with quantitative and qualitative data to evidence genuinely and quality. In 11 juices prepared at lab level according to pH, acidity and soluble solids specifications and of high consume (peach, strawberry, mandarin orange, mango, apple, maracuya, orange, melon, pear, pineapple and grape) it has been determined: A) the microscopic cellular characteristics (WaIlis metbod) and b) free amino acid index, by means of the formalin index (an A.O.A.c. official method). The same parameters were analyzed in 18 rmnufactured tradermrk juices that are commercialized in the country. This result is reported graphically in photographs taken at tbe moment of CE microscopic ...
