Abstract: Sugar esters are separated and purified by forming an aqueous mixture containing salt from which water is distilled off to remove unreacted volatile material from the raw sugar esters. Thereafter an organic extraction solvent is mixed into the aqueous mixture which upon standing separates into a plurality of layers containing sugar esters of different degrees of substitution which are recovered from the separated layers. The separated sugar esters may be further refined by mixing with water and by freeze drying the aqueous mixture.

Abstract: The invention relates to an improved process for the synthesis of sugar esters carried out in a substantially anhydrous system and in the presence of an organic acid chloride. Any of the known available sugars may be used and in particular hydrolyzate sugars derived from starch are effectively employed in accordance with the present invention to produce sugar esters having superior emulsifying characteristics for use as an ingredient in food products for human consumption.

Abstract: Improved bottom for a seamless metal container body wherein the central portion of the bottom that includes a stiffening embossment is joined to the other portions of the bottom in an improved manner by a hinge-like section that permits selected and controlled outward flexing or bulging of the bottom when the container is sealed and subjected to internal pressures developed by the contents of the container. Despite such outward flexing of the bottom, the container still is provided with a stable bottom to rest upon in its sealed and pressurized condition.
