Claim 6:
7. A process for producing the particulate delivery system according to claim 1, wherein the process comprises forming the coated particles by the sequential steps of:
(a) producing the particulate solid core by a spray drying process;
(b) spraying at least one fermentable uncrosslinked biopolymer onto the particulate solid core;
(c) contacting the at least one fermentable uncrosslinked biopolymer with a crosslinker to form the inner coating which covers the solid core comprised of the at least one crosslinked biopolymer;
(d) spraying the material resistant to stomach and small intestine conditions onto the inner coating to thereby form the outer coating of the particulate delivery system; and thereafter
(e) drying the coated particles.
