摘要:
The present invention relates to an emulsion comprising an aqueous gelled outer phase, a non-aqueous intermediate phase and an aqueous inner phase containing an active ingredient incompatible with the gelled outer phase, wherein the inner phase containing the active ingredient is encapsulated by the intermediate phase. Said emulsion finds suitable application in an antiperspirant, as a sustained release drug or personal hygiene products.

A controlled release formulation based on a gel matrix for controlled release of a pharmaceutical, a foodstuff, or as a component of a diagnostic assay apparatus.

This invention relates to calcium alginate gels and in particular to encapsulated calcium salts dispersed in soluble alginate systems. In this way, homogeneous calcium alginate gels can be prepared without precipitation of the alginate as fibrous calcium alginate. These gels are useful in a variety of food products.
摘要:
An omelette mix is prepared from a liquid egg product, which may be, for example, whole egg, egg white, egg yolk, a de-chloresterized or artificial mix, or any combination of two or more of the foregoing, by adjusting its pH, preferably with citric acid, then adding to it a hydrocolloid, comprising an alginate, adding a multivalent metal salt of only low solubility in water, e.g. calcium sulphate dihydrate, in order to facilitate any required cross-linking of the hydrocolloid molecular chains, mixing thoroughly to form a homogeneous material, forming this material into any desired shape and freezing or chilling it to produce a stable intermediate material that can readily be quickly heated to give an omelette in form ready for consumption. In general sodium chloride will be introduced into the mix, conveniently with the hydrocolloid, in order to enhance the flavour of the omelette. A sequestrant is desirably added to control the release of the multivalent metal salt and thus regulate the speed of the cross-linking reaction.

摘要:
lons are controllably released into solution by novel blends of a hydrocolloid that is one or a combination of guar, oxidized guar, carboxymethyl guar, depolymerized guar, hydroxyalkyl guar, polyvinyl alcohol, carboxymethyl cellulose, xanthan gum, cold-water-soluble locust bean gum, cold-water-soluble starch, hydroxyethylated starch, and hydroxypropylated starch, and a calcium, barium, or strontium salt, in which the ratio of salt to hydrocolloid ranges from 10:1 to 1:20, based on total dry weights. They are mixed with a soluble alginate in relative amounts such that the bivalent cation level is the amount theoretically necessary to convert 16-60% of the soluble atginate. The mixtures are especially useful in alginate print paste compositions and in preparation of various foods for humans and animals.
