Abstract

The invention provides compositions and methods for the enzymatic treatment (''bleaching'' or ''de-colorizing'') of chlorophyll-comprising compositions, e.g., algae preparations, chlorophyll-containing or chlorophyll-contaminated feeds, foods or oils, for example, vegetable oils, including oils processed from oilseeds, such as canola (rapeseed) oil or soybean oil, or oil fruits, such as palm oil.In one aspect, the invention provides methods using a chlorophyllase enzyme for the enzymatic hydrolysis of chlorophyll in an algae, an animal (e.g., a fish) or plant preparation, a food or an oil. In one aspect, the chlorophyllase is immobilized onto a silica. The invention also provides compositions of manufacture and detergents.

Description

technical field

[0001] The invention relates to the industrial processing of food, feed or vegetable oils, plant and animal products and the fields of enzymology. In particular, the present invention provides compositions and methods for the enzymatic treatment ("bleaching" or "decolorization") of chlorophyll-containing compositions or chlorophyll-contaminated compositions which For example, algae, animal or plant preparations, food, feed or oils, such as vegetable oils, including oils processed from oilseeds such as rapeseed (rapeseed) oil or soybean oil, or oils processed from oilseeds such as palm oil. In one aspect, the invention provides a method of enzymatically modifying chlorophyll, eg, in algae, animal or plant preparations, or food, feed or oil using a chlorophyll catabolizing enzyme (eg, chlorophyllase). Background technique

[0002] Vegetable oils from oilseeds such as canola or soybean, or from oilseed fruits such as palm, contain chlorophyll. Chlorophyll is r...
