Patent number: H1014Abstract: A method of making cherries of the maraschino type is provided. Sulfite brined cherries are leached to reduce residual sulfur dioxide content to at most about 100 ppm. The leached cherries are then immersed in a sweetener syrup consisting essentially of high fructose corn syrup, solids from crystalline fructose, and a red coloring agent. The syrup has a sweetener solids content insufficient to cause substantial osmotic shock to said fruit, but said immersing raises the solids level of said cherry fruit and imparts thereto a red color. The use of the particular sweetener syrup allows the solids level of the fruit to be raised much faster than in conventional maraschino cherry manufacture and yet collapse of the fruit is avoided. Also provided is a method of packing frozen fruit.Type: GrantFiled: November 20, 1989Date of Patent: January 7, 1992Assignee: A. E. Staley Manufacturing CompanyInventors: Charles W. Kraut, Michael E.
