This document describes a process of producing gel microparticles, which are consistent in size and morphology. Through the process of coacervation, large volumes of gel microparticle slurry can be produced by scaling up reactor vessel size. Particles can be repeatedly dehydrated and rehydrated in accordance to their environment, allowing for the storage of particles in a non-solvent such as ethanol. Gel slurries exhibit a Bingham plastic behavior in which the slurry behaves as a solid at shear stresses that are below a critical value. Upon reaching the critical shear stress, the slurry undergoes a rapid decrease in viscosity and behaves as a liquid. The rheological behavior of these slurries can be adjusted by changing the compaction processes such as centrifugation force to alter the yield-stress. The narrower distribution and reduced size of these particles allows for an increase in FRESH printing fidelity.
摘要:
A capsule comprises an encapsulated material and a capsule wall encapsulating the encapsulated material, wherein the capsule wall includes a N-acetylglucosamine/glucosamine copolymer or a derivative of such a copolymer, wherein the N-acetylglucosamine/glucosamine copolymer or a derivative of such a copolymer is derived from a raw material which has a non- animal origin. The capsules are found to have significant compression resistance whilst minimising the amount of polymer incorporated into the capsule wall, are advantageously stable in a range of products including when associated with commercially available protease containing, biological liquid laundry products.

Ce procédé comporte les étapes suivantes : - écoulement, dans un conduit de circulation (38), de gouttes (12) d'une première phase dans une deuxième phase sensiblement immiscible avec la première phase, chaque goutte comprenant un cœur formé de première phase et une écorce formée d'une couche de coacervat interposée entre la première phase et la deuxième phase; - récupération d'une dispersion comprenant des gouttes (12) et de la deuxième phase dans un récipient (33); - injection d'une solution (62) d'augmentation de la viscosité de la deuxième phase dans le conduit de circulation (38) ou à la sortie du conduit de circulation (38), en amont du récipient (33).
摘要:
In the disclosed method, a first fluid (36) comprising the first phase and a first precursor polymer of the coacervate in the first phase is supplied, and drops of the first fluid (36) are formed in a second fluid (40) that is to form the second phase (16). The method includes the steps of introducing a second precursor polymer of the coacervate into the second fluid (40), and creating the coacervate layer by having the first precursor polymer interact with the second precursor polymer at the interface between the first phase (14) and the second phase (16) when each drop (12) is formed or once each drop (12) has been formed.
摘要:
Complex coacervates incorporating one or more hydrophobic substances are provided, that are stable in certain aqueous systems and food products. The coacervates may be used as an ingredient in food products. e.g., in beverages, dry foods, and semi-moist foods. Methods for producing the complex coacervates and food products are also disclosed herein.
