JPH04320660A - Production of corbicula extract - Google Patents

Abstract

PURPOSE:To improve the transparency of corbicula extract liquid by sufficiently removing the harshness of the extract. CONSTITUTION:Corbicula extract is prepared by (1) adding water to corbicula with shell after removal of sand and heating the corbicula under pressure, (2) removing the shell from the boiled corbicula, (3) filtering the remaining liquid and heating the filtrate to evaporate the water and obtain a concentrated corbicula extract, (4) adding ascorbic acid, carotene, fructose, flavor and water to the concentrate and (5) heating the mixture for >=30min while removing the harshness floating on the liquid surface.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] This invention relates to a method for producing freshwater clam extract. More specifically, the present invention relates to a method for producing a freshwater clam extract from which scum has been sufficiently removed.

0002

[Prior Art] Regarding freshwater clams, vitamin A130I. U. , vitamin B10.04mg, vitamin B2O. 15mg, vitamin B 1215μg, vitamin C 10mg, calcium 1
80mg, protein 15g, fat 1.8g, iron 21m
It is said to contain g.

[0003] Vitamin B12 contained in freshwater clams
Its effectiveness in preventing pernicious anemia has been pointed out.

[0004] Therefore, the inventor attempted to produce a freshwater clam extract. To obtain freshwater clam extract, first obtain a freshwater clam concentrate by pressurizing and heating freshwater clams with shells. Ascorbic acid as a quality improver to make it easier to drink, carotene as a coloring agent, fructose, fragrance, and water were added to the mixture, and the mixture was further heated to remove the bitterness to obtain a freshwater clam extract liquid.

[0005]

[Problems to be Solved by the Invention] However, unless ascorbic acid, carotene, fructose, flavoring, and water are added to the freshwater clam concentrate and water is removed while heating, sufficient darkness cannot be removed, and after bottling, the liquid remains at the bottom of the bottle. There was a problem that precipitated and the transparency of the freshwater clam extract liquid decreased.

[0006] However, it has been found that when the scum removal process is performed while heating, no scum precipitate is observed at the bottom of the bottle even after bottling, and no decrease in transparency is observed.

[0007]

[Means for solving the problem] This invention is based on these findings,

[0008] A process of adding water to the sanded clams with shells and heating under pressure, followed by a process of removing the shells and flesh, filtering the remaining liquid, heating, and evaporating water to obtain a concentrated liquid of freshwater clams. a step of adding ascorbic acid, carotene, fructose, flavor, and water to the freshwater clam concentrate;
A method for producing freshwater clam extract, which comprises the step of removing scum formed on the water surface while heating the water.

[0009] and

[0010] A process of adding water to the sanded clams with shells and heating them under pressure, then removing the shells and flesh, filtering the remaining liquid, heating, and evaporating the water to obtain a concentrated liquid of freshwater clams. a step of adding ascorbic acid, carotene, fructose, flavor, and water to the freshwater clam concentrate;
A method for producing a freshwater clam extract, which comprises the step of removing the scum formed on the surface of the water while heating for 30 minutes or more.

[0011]

[Function] By removing the dirt while heating, no dirt remains in the obtained fresh clam extract, and the transparency does not decrease.

[Example] 10 kg of freshwater clams with shells were sanded out for 24 hours. Place the sand-blasted freshwater clams with their shells on in a pressure cooker for boiling. Add water at a ratio (by weight) of 1 part freshwater clam to 3 parts water, and heat under pressure at 110°C for 30 minutes. As the amount of water added increases, the concentration time increases. If the amount of water is small, the concentrate will not be extracted. Because freshwater clams are pressure-boiled, more extract can be obtained. Then, remove and remove the shell and flesh. Approximately 30 liquid left
Filter 1 liter and heat in a double boiler at 100°C for 1 hour to evaporate water to make 20 liters of freshwater clam concentrate. Next, in the total 100 liters, the freshwater clam concentrate is 20%, ascorbic acid is 0.25%, carotene is 0.01%, fructose is 12%, flavoring is 0.1%, and water is 67.64%. , remove the fragrance, add and heat at 100°C for 30 minutes. Heating produces a scum on the surface of the liquid, but while heating, remove the scum that forms on the surface of the water. Although the water evaporates due to heating, water is added so that the water ratio does not change. If the heating time is less than 20 minutes, sufficient scum will not be removed, and when the product is made into a bottle and bottled, scum will settle at the bottom of the bottle, reducing the transparency of the freshwater clam extract. Even if the product is heated for 30 minutes or more, there is no difference in the production of precipitates. Then add the flavoring, in this example lemon essence.

[0013] Then, it is bottled while heating at about 85°C. After bottling, sterilize by heating at 95°C for 60 minutes. Heating in this step is not necessary when bottling is done in a sanitary manner.

The obtained freshwater clam extract liquid exhibits a yellow color due to the coloring of carotene. As the fragrance, lemon essence is used in this example. Clam extract liquid 100l
