A packaged, shelf-stable, gelled natural fruit pulp, wherein the natural pectins of said fruit pulp have been substantially demethoxylated by the action of a pectinmethylesterase enzyme under ultra-high pressure (UHP) conditions. Also provided is a method of preparation of a packaged, ambient-stable, natural fruit product comprising the following steps: (a) comminuting a fresh fruit to provide a first fresh fruit pulp; (b) adding a pectin methylesterase (PME) enzyme to the first fresh fruit pulp; (c) packaging the first fresh fruit pulp and PME in a sealed, substantially oxygen- impermeable container; (d) incubating the fresh fruit pulp and PME at ultra-high pressure (UHP) to demethoxylate natural fruit pectins in said pulp and thereby convert the pulp to a dimensionally stable gel bar and render the product shelf-stable. |
