  • Publication number: 20230058376
    Abstract: A malto-dextrin composition with low DE value and low viscosity and the method for making the same is provided. The malto-dextrin comprises a blue value in the range of 0.02 to 0.28; a dextrose equivalent (DE) in the range of 3 to 10; and a viscosity lower than 26.3185*DE{circumflex over (?)}(?0.7593). The method for preparing the malto-dextrin composition comprises: dispersing raw starch in water to obtain a starch-water slurry; preheating the starch-water slurry with a jet-cooker for a first duration at a first temperature above 100° C. having a temperature variation no more than 0.8° C.; hydrolyzing the slurry by treating the slurry with ?-amylases for a second duration at a second temperature; and filtering the hydrolyzed slurry to remove insoluble residual proteins and fibers and obtain an un-fractionated malto-dextrin composition.

  • Publication number: 20210300661
    Abstract: A valve assembly is provided for use with a food storage container, including an opening formed in its lid member with at least one air channel formed between the container and the lid member. The valve assembly can be operated by a knob that, in a first position, unseats a check ball from a valve seat so that the valve assembly operates as a two-way valve able to work with a vacuum adapter in “marinate” mode or to open the lid member. In a second position, the check ball of the valve assembly unseats from the valve seat so that the valve assembly operates as a one-way valve that is operable to work with a vacuum adapter in “vacuum” mode to preserve the freshness of food contained therein. The valve assembly can be used with a vacuum system as part of a food storage container system.

  • Patent number: 5019289
    Abstract: The invention provides a phase stable liquid detergent composition containing at least one insoluble oxidant, comprising:(a) a liquid phase which comprises: (i) an effective amount of at least one surfactant selected from the group consisting of anionic, nonionic, cationic, amphoteric, zwitterionic surfactants, and mixtures thereof; (ii) a liquid carrier therefor, comprising water soluble or dispersible organic solvents, water, or a mixture thereof;(b) an effective amount of a water insoluble oxidant stably suspended in said liquid phase, which maintains oxidative stability, said water insoluble oxidant being an alkaline earth metal peroxide or a Group IIB peroxide; and(c) a stabilizer which is either a source of common ions or by buffering to a pH of greater than 8.

  • Patent number: 4919834
    Abstract: The present invention provides a package for a phase stable, liquid nonaqueous detergent, comprising:a plastic, relatively thin-walled container, said container having an end wall and a circumscribing side wall which narrows to a finish, and a liquid detergent contained in said container, said detergent comprising:(a) 20-90% of a liquid portion which comprises an alkoxylated nonionic surfactant;(b) 5-50% of a solids portion which comprises:(i) a builder;(ii) 0-20% of the detergent of an oxidant; said solids being stably suspended in said liquid portion, by means of(c) a phase stabilizing amount of a lower alkylated fused ring polyarylene sulfonate; and(d) 0-5% of a hydrolytic enzyme;whereby the phase stability of said liquid detergent in storage in said container is controlled, by the selection of either:(1) said container being constructed of a homopolymeric resin, said container having a minimum average cross-sectional dimension r/2 of at least about 6.
