Abstract: Powders of plant green juice having an improved stability and tastiness which are storable for a long period of time, characterized in that said powders comprise:(a) dry powders of the plant green juice obtained by squeezing fresh raw edible green plants and(b) a water-soluble alkaline naturally occurring mineral mixture dispersed uniformly in said dry powder,and the pH of a dispersion at the time of dispersing in water falls into a range of 6.2-9.5. The powders can be produced by adding a water-soluble alkaline naturally occurring mineral mixture to a plant green juice obtained by squeezing fresh raw edible green plants thereby to adjust the pH of said plant green juice to be a range of 6-9 and then spray-drying or lyophilizing the green juice.

Abstract: A process for producing a tear grass soy sauce, which comprises inoculating a koji mold for soy sauce in a koji substrate comprising a denatured proteinous material and a denatured carbohydrate material, at least a part of said carbohydrate material being tear grass, cultivating the koji mold to form a koji for soy sauce, adding water and sodium chloride to the koji to prepare moromi, fermenting the moromi, and separating the liquid layer from the fermentation product; and a tear grass soy sauce obtained by aforesaid process.

Abstract: A product of fermentation of the water extract of tear grass with a Lactobacillus strain, and foods and feeds comprising said fermentation product. The fermentation product containing useful ingredients of tear grass can be produced by inoculating a Lactobacillus strain in a culture medium containing the water extract of tear grass, and subjecting it to lactic fermentation.

Abstract: A lactic acid bacteria-fermented food product of a cereal germ is prepared, which comprises inoculating with lactic acid bacteria a culture medium containing a water extract of a cereal germ as a main ingredient, and then cultivating the lactic acid bacteria therein to a sufficient level to produce the lactic-acid bacteria-fermented food product.
