In Japan, deodorizing airflesheners are very popular to make air flesh by deodorizing odor in rooms, toilet as well as inside a car. There are in different features in deodorizing material of Gel and Liquid, in a shape of bottle from tall to low height, in bottle color and so on. These different features will influence the customer's feeling to the products of deodorizing airfleshener. This paper deals with the psychological evaluation of the features of deodorizing airfleshener on the SD scale with kansei words. The evaluated data were analyzed by Quantification Theory Type I that leads to the relational rules between the product feature and the kansei words. The beautiful and graceful kansei consists of low height, middle width deformed round shape, but easy operational feature is based on tall shape design. These results are helpful to develop a new product of deodorizing airfleshener.

The preparations of deodorizing fibers using medal-phthalocyanines have been investigated. The five metal-phthalocyanine derivatives(M-taPc, M=Fe, Co, Ni, Zn, Cu) were prepared in modest to good yields. The metal-phthalocyanine derivative as a deodorant material was introduced to fibers by a dyeing method. The deodorant activity(D.A.) of these deodorizing fibers was measured by chromogenic gas detector tubes. In comparison with untreated fibers, these deodorizing fibers was remarkably effective against $NH_3$ and CH3SH. More than 99% of ammonia can be removed within 20 min. The D.A.(%) of fiber adsorbed M-taPc was more than 80% after 90min.

The deodorizing responses of the steam distillate from some medicinal plants(G-3) on three representative malodors were evaluated by estimating the best estimate threshold(BET) of odor responses. With a single spray of G-3, the BETs of malodors such as ammonia, acetic acid, and ethyl acetate were found to increase 4.11, 32.6 and 13.1 fold, respectively, which indicated G-3 possessed a potent deodorizing activity. The deodorizing potency of G-3 was also demonstrated to be as high as and even higher than those of the commercial deodorizing agents.

Deodorizing activity of polyphenol cxidase (PPO) extracted from apples was investigated by measuring the changes of methyl mercaptan as an indicator of halitosis in human mouths. In the studies of apple extracts on deodorizing activity, the deodorizing activity was increased with the amount of apple extracts. In the cases of adding PPO to the low molecular fraction of apple extracts, the deodorizing activities were increased with the amount of the law molecular fraction of apple extracts and the reaction time of the extracts with PPO. Deodorizing activities of PPO is thought that o-quinone as an intermidiate produced by an oxidative reaction of PPO during enzymatic browning reactions may react with methyl mercaptan to form a non-volatile and sulfur-containing compound .

The preparations of deodorizing fibers using $TiO_2$ have been investigated. The fibers were coated with $TiO_2$ for the purpose of deodorizing by dipping fibers into the $TiO_2$ sol solutions and calcined at $450^\circ{C}$, $500^\circ{C}$ and $750^\circ{C}$ for 1 h after coating. The surface structure of the coated fibers was studied with XRD on the different preparation conditions of calcination temperatures. The deodorizing function of the prepared fibers was studied by the determination of the decomposing capability for $NH_3,\;CH_3SH\;and\;CH_3CHO$. The deodorant activity(D.A.) of these deodoriBing fibers was measured by chromogenic gas detector tubes. The deodorizing effect of the prepared fibers were shown to be similar for the three model compounds; 5wt% $TiO_2$ sol solution calcined at $450^\circ{C}$ < 5 wt% $TiO_2$ sol solution calcined at $500^\circ{C}$< 5 wt% TiO$_2$ sol solution calcined at $750^\circ{C}$.

The preparations of deodorizing fibers using $\textrm{TiO}_2$ have been investigated. $\textrm{TiO}_2$ is known to be an excellent photocatalyst for the degradation of organic and inorganic contaminants in water. $\textrm{TiO}_2$ catalyst have been supported on the glass fiber by a dip-coating procedure. The resulting materials have been characterized by XRD and SEM. The immobilized catalysts were tested in the photocatalytic degradation of $\textrm{NH}_3$, $\textrm{CH}_3\textrm{SH}$ and $\textrm{CH}_3\textrm{CHO}$. The deodorant activity(D.A.) of these deodorizing fibers was measured by chromogenic gas detector tubes. The efficient deodorant activity results have been achieved through the increase of $\textrm{TiO}_2$ sol concentration.

The preparations of deodorizing fibers using metalloporphyrines hove been investigated. The three metalloporphyrin derivatives(MTCPP, M=Mn, Zn, Sn) were prepared in modest to good yields. The metalloporphyrin derivative as a deodorant material was Introduced to fibers by a dyeing method. The deodorant activity(D.A.) of these deodorizing fibers was measured by chromogenic gas detector tubes. In comparison with untreated fiber, these deodorizing fibers was remarkably effective against $NH_3$ and $CH_3$SH$. More than 98% of ammonia can be removed within 20 min.. The D.A.(%) of fiber adsorbed MTCPP was more than 80% after 90min..

It was determined the effect of deodorizing temperature on forming amount and its composition of trans fatty acids by GLC in corn oil. Trans fatty acids were detected a trace amount at the low temperature deodorizing as 240~25$0^{\circ}C$, but it s amounts were showed to 0.30, 0.57, 0.64 and 0.81% at the high temperature deodorizing as 255~27$0^{\circ}C$, respectively. The isomerization phenomenon was remarkably in order that double bond number might to increase, tt, and ttt type were not detected nearly, that the ct, tc, cct and tcc type were detected to the large amount, respectively.

To improve the deodorizing and antibacterial performance of various fabrics (cotton, silk and wool) dyed with pomegranate(Punica granatum L.) extract without mordants, natural colorant solutions, which were extracted from pomegranate using water as an extractant at $90^{\circ}C$ for 90 min with a various liquor ratio (solid natural colorant material/solvent water, weight ratio) from 1:100 to 1:5 were used. To achieve the highest K/S and the deodorizing and antibacterial performance, the best liquor ratio, dyeing bath ratio, dyeing temperature and dyeing time were found to be 1:10, 1:50, $80^{\circ}C$ and 60 min, respectively. The deodorizing performance of dyed cotton, silk and wool fabrics against acetic acid vapor were found to be95,70,90%,respectively. However, all the dyed fabrics displayed outstanding deodorizing performance(99%) against ammonia gas and antibacterial performance(bacteriostatic reduction rate:99.9%) against Staphylococcu aureus and Klebsiella pneumonia(bacteriostatic reduction rate: 99.9%). It is worth noting that pomegranate (Punica granatum L.) colorants notably enhanced the deodorizing and antibacterial performance of cotton, silk and wool fabrics.
