Abstract

(57) [Summary] [Purpose] The hot water extract of Chlorella alga is a water-soluble component,
That is, it contains various amino acids, sugars, seasoning substances, animal growth promoting substances and other water-soluble useful substances, but it has a drawback of low commercial value because it has a dark brown color, and this defect was corrected. The aim is to obtain a hot water extract of Chlorella. [Structure] A chlorella algal body hot water extract obtained by subjecting chlorella algal bodies to hot water extraction treatment
It is characterized by performing a centrifugal separation process at 00 rpm.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chlorella alga body hot water extract retaining a green color and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, in the production of chlorella-containing foods, chlorella wet cake (live algae) is suspended in fresh water, heated at 80 to 100 ° C. for about 2 to 5 minutes, cooled, and then subjected to a centrifugal separation treatment. To obtain a chlorella hot water extract (Japanese Patent Publication No. 55-22073), and in the production of jelly-like foods, the chlorella concentrated liquid is mixed with a plate heater 1
To obtain chlorella hot water extraction by heating at 00 ° C for 5 minutes, cooling, and centrifuging to remove algal cells (Japanese Patent Publication No. 54-2).
No. 2500) is known.

DISCLOSURE OF THE INVENTION The inventors of the present invention have found that the hot water extract of Chlorella algal cells is a water-soluble component contained in the Chlorella algal cells, that is, various amino acids / water-soluble vitamins, sugars, nucleic acid-related substances. Substances and other useful ingredients such as animal growth promoting substances and seasoning substances are included, but the color of the extract itself is dark brown and the commercial value is low, so about obtaining green chlorella alga body hot water extraction As a result of research, the present invention has been achieved.

[0004]

According to the present invention, a chlorella algal cell suspension is heated and extracted at 80 to 100 ° C. for 2 to 10 minutes, and the heated extract is cooled to 8000 to 8000.
It is a green extract derived from Chlorella algal cells, which consists of an extract that has been subjected to centrifugal separation at 10000 rpm and the residue has been separated.

The present invention also provides a chlorella algal cell suspension,
The heated extract obtained by heat treatment at 80 to 100 ° C for 2 to 10 minutes is cooled to 8000 to 10000r.
A method for producing a green extract derived from Chlorella, which comprises centrifuging at pm and separating the residue, optionally adding a coloring agent, and preferably storing in a vacuum concentrated state at low temperature. Is.

[0006] A heated hot water extract obtained by subjecting a suspension of purified chlorella algal cells to water to heat treatment at 80 to 100 ° C for about 2 to 10 minutes is cooled to 800
Centrifuging at 0 to 10000 rpm
This is because the cell wall of a hard chlorella algal body is almost crushed and chlorophyll can be present in the extract, and the extract is prevented from becoming a brownish color to obtain a green chlorella hot water extract.

The green chlorella algal cells obtained by the centrifugation treatment according to the present invention are kept at a low temperature of 40 to 60 ° C. in a vacuum state so that the green color of the extract does not change and the concentration of the extract does not change. This is for stability.

If necessary, the chlorophyll green pigment, spirulina blue pigment and gardenia yellow pigment are added in appropriate amounts to the green chlorella alga body extract obtained by centrifugation and separation as described above, if necessary. The reason why they are mixed one by one is because it is preferable in order to stably maintain the color of the green extract.

[0009]

[Example] A hot water extract obtained by heat-treating a suspension of chlorella algal cells, which had been subjected to clean culture and washed with water, at a temperature of about 100 ° C. for about 5 minutes with cooling, while cooling, for about 1 minute at 900 ° C.
At 0 rpm, a mixed pigment liquid was prepared by mixing equal parts by weight of gardenia-derived blue pigments, chlorophyll pigments and spiruna-derived pigments (phycocyanin pigments) with the green chlorella alga body extract obtained by separating the residue by centrifugation. And mix 5
After being kept in a vacuum state at 0 ° C., it was sterilized, sterilized, and then filtered through a filter cloth of about 100 mesh to obtain a green chlorella extract.

The extract derived from Chlorella algal cells obtained in the present invention is appropriately concentrated / diluted or, as it is, is mixed with green juice, orange juice, green tea or the like, or an appropriate step for food. Thus, for example, in the case of gyoza skin, uguisu mochi, etc., it is preferable that they are mixed and used when kneading the dough. The green food and drink is preferably concentrated or the green extract is used as it is, and the food and drink that does not like green is preferably diluted.

[0011]

INDUSTRIAL APPLICABILITY According to the present invention, an extract derived from a chlorella alga that has a high commercial value and stably retains a green color is obtained, and the obtained extract derived from a green chlorella alga is Thus, a useful Chlorella algal cell extract that can be concentrated, diluted, or used as it is in appropriate foods and drinks, and which can impart an orderly taste and other active ingredients to foods and drinks can be obtained.
