Prototype

According to Assocham, in India, 30 percent of the total harvest of agricultural crops have been discarded by lack of refrigerated storage facility.Refrigerated storage facility has been used only in the process of distribution, and it is lack in the retail market in rural areas and suburbs. In 2011,Refrigerator penetration rate in the cities is 43.8% , and villages is 9.4%. The penetration rate in rural areas is much smaller than the city group . Its cause is considered that is infrastructure facilities are not yet ready. To solve this problem, there is a need for method of preserving food products that do not require power in rural and suburban markets.We assume that it is used in situations such as the India, devised Flavorator.

This is design of Flavorator.

・A layer of vacuum keeps the temperature as a thermos.

・To prevent the　contact of recombinants and foods, the container of the medium is covered by a triple filter.　Recombinants are larger than the mesh of filter, so they can't go through a triple filters , but fragrance is able to pass through because its molecules are smaller than the mesh.

・Recombinants differs depending on the temperature in a region which use Flavarator.

We experimented to ascertain the antibacterial aroma substances.

(A) was put mashed garlic 5g in the bottom of box.We left the two pork in the box at 18℃ for 2 months.2 months later, Left pork (A) didn’t change the color. Right pork (B) changed Pink to Brown.This result shows that antibacterial fragrance had inhibited the growth of bacteria.

fig1：Storage of food in geraniol A:ddH2O（stock solution, 300 μl）B:geraniol（stock solution, 300 μl） Incubation: 35 days Temperature: room temperature Chopsticks dipped in suspension of Penicillium was put in the center of the bread. Penicillium was cultured among the left box(A). However, Penicillium wasn’t cultured among the right box(B), suggesting that Penicillium can’t be cultured in a state where geraniol is filled. This experiment indicate that geraniol might be the effect of suppressing the growth of bacteria.

We found that fragrance have antibacterial activity by these results. So, we considered It can be preserve foods in Flavorator if our recombinants synthesized antibiotic fragrance.
