Abstract: A food storage and preparation bag at least one sheet of flexible sheet material assembled to form a semi-enclosed container having an opening defined by a periphery and a closure for sealing the opening to convert the semi-enclosed container to a closed container. The opening defines an opening plane and the sheet material includes a first region and a second region being comprised of the same material composition. The first region undergoes a substantially molecular-level deformation and the second region initially undergoes a substantially geometric deformation when the sheet material is subjected to an applied elongation along at least one axis. The first region and the second region are visually distinct from one another, wherein the second region includes a plurality of raised rib-like elements and the first region is substantially free of rib-like elements.

Abstract: A soft web material which exhibits an elastic-like behavior along at least one axis when subjected to an applied and subsequently released elongation. The web material includes a strainable network having a plurality of first regions and a plurality of second regions of the same material composition. A portion of the first regions extend in a first direction while the remainder extend in a second direction perpendicular to the first direction to intersect one another. The first regions form a boundary completely surrounding the second regions. The second regions include a plurality of raised rib-like elements.

Abstract: Disclosed is a method for recovering residual juice solids present in the extractor core or waste material from citrus juice extraction. In this method, citrus fruit is processed in a juice extraction and finishing system to provide a primary juice stream and extractor core or waste material containing rag, seeds, peel plugs and residual juice solids. Without adding water, the extractor core material is processed in a centrifugal filter to provide a secondary juice stream. The preferred citrus fruit is orange juice and the preferred extraction system is a reciprocating cup-type juice extractor.

Abstract: Detergent compositions comprise a detergent surfactant, a pure enzyme, preferably a proteolytic enzyme, and a mixture of aluminosilicate ion exchange material and water-soluble nitrilotriacetate to provide unobviously superior enzyme cleaning performance.
