FUNCTIONAL FOOD COMPOSITION FOR IMPROVING FRUIT CALCIUM ABSORPTION RATE COMPRISING THE CHITOSAN NANOPARTICLES

摘要

PURPOSE: A functional food composition for promoting fruit calcium absorption rate is provided to improve bioavailability of calcium included in fruits by adding manufactured chitosan nanoparticles with tripolyphosphate as a gelling agent which is harmless to a human body. CONSTITUTION: The functional food includes chitosan nanoparticles, fruits or fruit squeeze. The concentration of the chitosan nanoparticles is 0.05-5 weight%. A form of the functional food is one among a dry powder form, a squeeze for, and a jelly form. The chitosan is dissolved in organic acid liquid. The manufactured tripolyphosphate liquid is added in the chitosan liquid. The organic aid is a component selected from a group consisting of lactic acid, acetic acid, propionic acid, formic acid, ascorbic acid, and tartaric acid.
