Although noni (Morinda citrifolia L.) has been used to treat a broad range of diseases, many people avoid consuming the fruits because of its unpleasant odor caused by organic acids. Even though ion exchange resins were able to reduce the odor, it also reduced beneficial antioxidant compounds. Thus, to preserve antioxidants (phenolic compounds) during deacidification, it is important to characterize the interaction of ion exchange resin with both organic acids and phenolic compounds. Adsorption capacities of organic acids and phenolic compounds commonly found in the noni fruit were conducted onto Amberlite IRA 67 resin. The phase contact time to reach equilibrium for octanoic acid and hexanoic acid compounds was 326.86 and 160.72 min, respectively. The values of initial adsorption rate, 1/K1, and adsorption extent, 1/K2, decreased with the increase of initial concentration for all compounds studied. Results for all the compounds studied fitted well to the Langmuir model. The effect of pH in adsorption capacity of the actual system (noni juice) has been applied based on the model system studied.

Quantitative Indicators

Production of plant products, including juices around the world increases continuously. In the fruit and vegetable juices contain a significant amount of monosaccharides (glucose and fructose), organic acids, vitamins, phenolic compounds, mineral substances and other biologically active components that determine the nutritional and dietary value. For the prevention of various diseases associated with impaired metabolic processes, we developed a new technology of preparation of food by blending juice of pumpkin, quince and persimmon. Thus prepared organic blended juice contains a substantial amount of free glucose and fructose, different phenolic compounds, a sufficient amount of organic acids, mineral elements, including iodine and other components that determine its nutritional and biological value. In prepared juices were evaluated the quantitative indicators of β-carotene, vitamin C, glucose and fructose, sucrose, starch, pectin substances. Also in the atomic absorbtion spectrometer Analyst 400 (PerkinElmer, USA) was analyzed content of the organic acids and phenolic compounds. Prepared juices were tested in accordance with 10 point scoring scale. It is established that all juices contain a sufficient amount of the minerals. In pumpkin and quince juices not contain iodine while it presents in sufficient amount in persimmon juice that’s why in the blended juice mineral in addition to mineral elements iodine are contained. In pumpkin and persimmon aliphatic acids are contained in small amount. For this reason during the blending process was used quince juice which is rich in aliphatic acids. The blended juice is light straw color, with delicious flavor, a slight astringent property and a balanced taste.
