Patent
A chlorella extract-containing product of excellent safety and storage stability is provided without using a benzoate, which is a common preservative. A chlorella extract-containing product containing a capsicum extract at 0.020-1.63% by weight on a dry weight basis relative to a chlorella extract in an aqueous liquid for drinking having the chlorella extract as an principal ingredient. This chlorella extract-containing product is to be used as a chlorella -containing beverage or a chlorella -containing food additive. A method for improving the storage stability of a chlorella extract-containing product, comprising adding a capsicum extract to a chlorella extract at 0.020-1.63% by weight on a dry weight basis in an aqueous liquid for drinking having the chlorella extract as an principal ingredient.
1. A composition consisting essentially of brewed vinegar, a capsicum extract and chlorella pyrenoidosa extract which is obtained by suspending chlorella algal cells of chlorella pyrenoidosa in an aqueous solvent to obtain a suspension, the suspension obtained being heated to about 100 degrees Celsius with stirring, allowed to stand for a given length of time and the algal cells being removed therefrom by fractionation to obtain an aqueous solution, the obtained aqueous solution being concentrated, subjected to a deproteinization step and a sterilization step to yield said extract.
2. The composition according to claim 1 , wherein said composition is an aqueous liquid for drinking.
3. The composition according to claim 1 , wherein said composition is a chlorella extract-containing food additive.
4. The composition according to claim 1 , wherein said capsicum extract is contained at 0.020-1.63% by weight on a dry weight basis relative to said chlorella extract.
5. The composition according to claim 2 , wherein said capsicum extract is contained at 0.020-1.63% by weight on a dry weight basis relative to said chlorella extract.
6. The composition according to claim 3 , wherein said capsicum extract is contained at 0.065-1.63% by weight on a dry weight basis relative to said chlorella extract.
7. The composition according to claim 1 , wherein said chlorella extract is contained at 30-60% by weight.
8. The composition according to claim 7 , further containing malic acid at 0.5-1.5% by weight.
9. The composition according to claim 1 , wherein said capsicum extract has been added to a liquid having a chlorella extract as a principal ingredient by adding a shelf life extender consisting essentially of a capsicum extract and brewed vinegar, said shelf life extender including said capsicum extract at 3-40% by weight and said brewed vinegar at 50-90% by weight.
10. The composition according to claim 9 , wherein said capsicum extract was obtained by extraction with water solvent.
11. The composition according to claim 4 , wherein said capsicum extract has been added to a liquid having a chlorella extract as a principal ingredient by adding a shelf life extender consisting essentially of a capsicum extract and brewed vinegar, said shelf life extender including said capsicum extract at 3-40% by weight and said brewed vinegar at 50-90% by weight.
12. The composition according to claim 11 , wherein said capsicum extract was obtained by extraction with water solvent.
