A Japanese powder made by fermenting rice germ and soybean with lactic acid bacteria of plant origin and combining the extract with yucca and quillaja, two saponin-rich plant extracts, on a resistant dextrin and galacto-oligosaccharide base. The producer suggests 300 to 500 mg a day; the powder is acidic, was used in hard capsules in the producer's studies and is confirmed for heated jelly sticks.

This page lists the designs of the producer's studies, not claims. Function wording on a finished product has to fit your market's rules and your own substantiation, so plan it with your regulatory adviser before you formulate.
The producer reports a vesicle peak by HPLC-SEC, but vesicle count, size and strain origin are not in our documents, and whether the word may appear on a label differs by market. Decide early how much of your story rests on it.
The formula contains a soybean-derived ingredient. GMO status, a full allergen declaration and halal or kosher certificates are not part of the documents we hold; list what you need so we can request it from the producer for your order.
The producer suggests 300 to 500 mg a day. The powder is acidic and has a sour-sweet taste with a faint astringency, so tell us the format before we send a sample.
We hold the producer's specification, nutrition values and safety test summary. Ask for the lot Certificate of Analysis and SDS with your quotation, and list anything else your vendor file needs.

This powder joins two parts. The first is an extract of rice germ and soybean fermented with lactic acid bacteria of plant origin. The second is a pair of plant extracts, yucca and quillaja, both rich in saponins. They are carried on resistant dextrin and galacto-oligosaccharide syrup, with citric acid.
The Japanese producer developed the powder for etiquette and odor-care products and has studied it in human, animal and laboratory tests; the developer's guide below lists what each study examined. It is aimed at brand owners and contract manufacturers developing daily odor-care supplements, fermentation-based concepts and pet products; one of the producer's studies was run in cats.
The producer states the powder can be formulated in any dosage form, and its human studies used hard capsules. It has also confirmed use in jelly sticks, where the formula meets an acidic environment and heating. With a suggested daily amount of 300 to 500 mg, it fits one or two capsules, a tablet, a stick pack or a jelly stick. The powder itself is acidic, so check taste and compatibility in your matrix.
If you need a finished product rather than the raw material, we also make capsules, sticks and tablets at our own Tomioka Plant in Gunma, Japan, from 5,000 units per SKU.

The notes below describe the components of this powder and published research on them. They are a reference for product developers, not claims for this ingredient or for any finished product.
Rice germ is the embryo of the rice grain, and soybean is the seed of Glycine max. In this powder both are fermented with lactic acid bacteria of plant origin, and the fermentation extract is the base of the formula. Our documents do not name the bacterial strain.
Saponins are plant glycosides: a water-loving sugar chain joined to a fat-loving aglycone. This amphiphilic structure lets them form stable foams and complexes with other molecules, which is why foods use them as natural emulsifiers and foaming agents [1].
Yucca is one of the main sources of steroidal saponins, and yucca extracts are sold as surfactant additives for beverages, animal feed and cosmetics; a 2021 review describes 108 saponins from eight Yucca species [2]. Quillaja saponaria, the Chilean soapbark tree, supplies triterpenoid saponins from its bark [3]. In the EU, quillaia extract (E 999) is obtained by aqueous extraction of the milled inner bark or wood of the tree and is used as an emulsifier and foaming agent; in its 2019 re-evaluation EFSA set an acceptable daily intake of 3 mg saponins per kg body weight per day for this additive [4]. In the United States, quillaia (Quillaja saponaria) and Mohave yucca (Yucca schidigera) are both listed among natural substances that may be used in food in conjunction with flavors [5].
Our documents name the ingredients as yucca extract and quillaja extract; they do not state the species or the saponin content.
A 2026 review of yucca extract as a feed additive in pigs, poultry, ruminants and fish covers studies on growth, ammonia-nitrogen metabolism and ammonia and methane emissions. Its authors note that the size and consistency of the reported effects vary considerably across species, dose and conditions, and that most evidence comes from controlled trials rather than commercial-scale validation [6].
Skatole (3-methylindole) is a potent malodorous compound formed when microbes break down the amino acid tryptophan, and it has an extremely low odor threshold. A 2026 review written for livestock production summarizes how dietary protein, gut microbiota and environmental conditions drive its formation [7].
Bacteria used in food fermentation, including lactic acid bacteria, release extracellular vesicles: spherical, membrane-bound particles of roughly 20 to 400 nm. Research on their properties and on how they interact with host cells has advanced quickly, and reviewers also point to open concerns about using them as postbiotics [8]. A 2026 review adds that methods for isolating them and characterizing their heterogeneity are not yet standardized, and that regulatory frameworks are still to be developed [9].
The producer calls the vesicles in this powder exosomes and reports a peak by HPLC-SEC at the retention time it assigns to them. Vesicle count, size distribution and strain origin are not part of our documents.
The producer has run the studies below with this powder. They are producer data, not peer-reviewed publications, and we describe their design only; they are not claims for this ingredient or for a finished product.
The producer also reports safety tests: acute oral toxicity in rats with an LD50 of 2,000 mg/kg body weight or more, a 13-week repeated oral dose study in male and female rats with a NOAEL of 2,000 mg/kg body weight or more, and a negative bacterial reverse mutation (Ames) test.
The powder is supplied as a food raw material. How a market classifies the finished product, which functions it may claim and whether the word exosome may appear on a label are decided by that market's rules, and registration of the finished product sits with the importer or brand owner. Check the route for your market before you formulate.
