The technology overview of Biocoats is to provide dietary supplements materials from biologica polymers, functional and healthful foodstuffs through discovery of metabolism improving substances from various biological resources (plant/animal/microorganism), functional and healthful foodstuffs through discovery of metabolism improving substances from various biological resources (plant/animal/microorganism), ( substitute fuels and extraction of functional substances by using wastes and scraps, wasabi extracts through encapsulation and micro-carrier technology and the materials of hard capsules made of vegetable polymers.


Among the technology, the core technology of Biocoats is to provide alginate-salt microcapsule encapsulated extract from Wasabia japonica as environment-friendly substances.


Background and unmet needs:


Eye-opening development of science and technology and consequent increase of national incomes have changed a main item of dietary patterns into meat, which increases various adult diseases like cancers. The generation of such diseases is supposed to be linked to foodstuffs or changing dietary patterns through numerous surveys. The demand for health-oriented foodstuffs has recently been increasing, while functional materials from the nature are spotlighted in the food industries. For instance, wasabi has been scrapped except its roots, even though its usefulness has recently been recognized.


Discovery and Achievements: 


(1) Preparation of alginate-salt microcapsule encapsulated extract from Wasabia japonica


Biocoats succeeded in making wasabi scrapped so far available widely by offering alginate-salt microcapsule type of extracts as small as 100~200 nm from stems and leaves of wasabi with the use of AIT (Allyl isothiocyanate).


(2) Anti-microbial effect of microcapsule encapsulated AIT extracted from Wasabia japonica


As shown above, the alginate-salt microcapsule encapsulated AIT extracted from Wasabia japonica has anti-microbial effect on both gram positive and gram negative bacteria, particulary high anti-microbial activities against Streptococcus mutans(plaque bacteria), pathogen E-coli 0157, Vibrio parahaemolyticus and Vibro vulnificus. 



3) The expiration date extension of a packaged bean curd


Biocoats added alginate-salt microcapsule encapsulated AIT to the packaged bean curd, stored for 14 days at 4? and measured total viable bacterial count. As n Fig. 3 below, a result, a general bean curd went bad in 5-8 days under cold storage(5-10?), but in the case of the bean curd added with 300 ppm AIT, expiration date was more extended 6 day than the general bean curd.

4) The application of alginate-salt microcapsule to various products


The soap, toothpaste and hand cream added with alginate-salt microcapsule with AIT have anti-microbial activities against pathogen E-coli 0157, Vibrio parahaemolyticus and Streptococcus mutans(plaque bacteria).


Therefore, wasabia extract encapsulated by alginate-salt has synergy effects.
