Red Dates To Clarify The Juice Processing Technology And Its Function Evaluation

Jujuba dates is a fruit with rich nutrient, including Polysaccharides,Lutin, Vitamin C, which are effective to human body's regimen and health. With theresearch on jujuba dates' processing technique, the thesis provides a series oftechnology parameter for the production of clarified juice of high quality andtheoretical references for increasing preservation rate of active substances. In addition,the thesis makes a systematic research and evaluation of the juice's function:Strengthen stamina, enrich blood and reduce blood fat, thus the theory of datesprocessing is enriched, which provides theoretical reference to produce function foodof dates.The experiment testifies as follow:1. This is the best dates juice extraction method with the highest extraction rate,heated in 60℃ for an hour and successively heated in 70℃ for another hour,mixed with water of l0 quantities and pectinase of 0.07% quantity then preservethe heat for six hours.2. There are 9 methods to clarify the juice with 90% transmittancy: NaturalClarification; Centrifugal Clarification, Clarification by freezing, TemperingClarification, Pectinase Clarification, PVPP Clarification, PVPP-TanninClarification, PVPMlutin Clarification, PectinastheinGlutinClarification.3. Among the above clarification methods, there are 4 methods wth the highestpreservation rate: Tempering Clarification, Pectinase Clarification, PVPPClarification, PVPMlutin Clarification.4. Dates juice has an evident effect of strengthening the subjects' body function.5. Dates juice can recover the subjects' anaemia caused by acethydrazide.6. Dates juice can recover the subjects' hyperIipidaemia caused by high-fat forage.
