Fat binder obtained from biomass resulting from beer production |
摘要 |
The present invention provides a polysaccharide rich composition comprising beta-glucan, chitin and chitosan, extracted from the cell wall of Saccharomyces cerevisiae from the by-product biomass resulting from a brewing process, the process for obtaining it and the uses thereof. The composition exerts, among other biofunctionalities, a selective fat binding effect so it is useful in the prevention and/or treatment of a disorder such as overweight, obesity, hypercholesterolemia, hypertriglyceridemia, blood hypertension and cardiovascular disorders. It can be formulated as edible, pharmaceutical or a veterinary product. |

1. A process to obtain a composition comprising beta-glucan, chitin and chitosan, extracted from the cell wall of Saccharomyces cerevisiae from by-product biomass resulting from a brewing process, comprising the following steps:
i) preparing a reactor with a NaOH solution in a concentration between 0.25 and 3 M with agitation and a temperature between 50 and 95° C.; ii) adding the by-product biomass resulting from the brewing process to the solution; iii) maintaining the conditions for at least 1 hour; iv) chilling the solution to room temperature, v) neutralizing the solution by at least one addition of an acidic solution or of water, until reaching pH 7, wherein when more than one addition is made, a step of separation of the solid product from the solution is performed between additions; vi) separating the solid product obtained in step (v) from the solution; vii) when the neutralization in step (v) has been made by the addition of an acidic solution, submitting the solid product to at least one washing with water and separating the obtained solid product; and viii) drying the solid product to constant weight and micronizing. |
