Process for the synthesis of polyol fatty acid polyesters

In a process of preparing a tea extract, the extract is adjusted to 20.degree.-80.degree. C., treated with tannase at pH=4-7 and then subjected to ultrafiltration at 2.degree.-90.degree. C. using a membrane with an average molecular weight exclusion point of at least 5000 Daltons (preferably at least 30,000 Daltons). The extract may finally be subjected to an additional filtration, preferably microfiltration. Also an instant a cold-water soluble tea powder or granulate is claimed.

Process of preparing a tea product

A process for refining soap-containing crude polyol fatty-acid polyester reaction product, the process including one or more high-temperature refining treatments and as the first step in the refining process, contacting the crude reaction product with an acid to substantially convert the soap into its corresponding free fatty acids, and the subsequent step of substantially removing from the crude reaction product any salts therein prior to said one or more high-temperature refining treatments.

Process for refining soap-containing crude polyol fatty-acid polyester

The present invention pertains to a process for refining soap-containing crude polyol fatty-acid polyester reaction product, comprising the step of contacting the crude reaction product with an aqueous acid solution to substantially convert the soap into its corresponding free fatty acids, the subsequent step of drying said crude reaction product to substantially remove any free-water therein, and the step of substantially removing from the dried crude reaction product any salts therein.

A process for refining organic-solvent containing crude polyol fatty-acid polyester reaction product, including the steps of distilling the crude reaction product to substantially remove the organic solvent, and subsequently subjecting the distilled reaction product to a bleaching treatment. The process allows an economic use of bleaching agents while achieving good color and color stability of the refined product.

Process for refining organic-solvent containing crude polyol fatty-acid

A method of preparing a water-in-oil emulsion spread by mixing a wet gelatin retentate wherein the off flavor has been reduced by membrane filtration to remove a low molecular weight fraction, with a fat phase.
