JOURNAL FREE ACCESSUsing grain thickness classification, the following experiments were undertaken to develop a classification system for drying according to moisture contents. Grain contents were examined and classified using a rotary grader and a 3.2mm sieve. The classified and non-classified grain groups were examined for flour qualities after drying with a recirculating batch drier.
Regarding grain contents, ash and protein contents of the thicker grain group are higher than those of the thinner grain group. Non-classified grains have a median value. Flour of thicker grains also has higher ash and protein contents than of thinner grains; non-classified grains are median.
Because of different initial moisture contents of grain groups, the recirculating batch drier finished drying of almost equal amounts of grain in the following order: thinner, non-classified and thicker. Thicker grains needed 7h longer than thinner to finish drying.
Flour color evaluated using the color grader value (CGV) was preferable in the following order: thinner, not-classified, and thicker. The order was opposite that of the order of ash and protein contents, both of which reportedly degrade the flour color.
Amylograph, farinograph and extensograph tests indicate that the groups have different dough properties, but those differences do not affect flour quality.View full abstractDownload PDF (928K) -

JOURNAL FREE ACCESSThe effect of electrolyzed water (EW) on bactericidal activity against the growth of microflora in mixed fresh-cut vegetables during storage at 10°C was investigated. Two procedures for decontamination were conducted: one was separately decontamination each kind of fresh-cut vegetables with EW before mixing and storage and other was first mixing the fresh-cut vegetables before decontamination with EW and storage. The first procedure proved more effective. Results showed after EW treatment the total plate count (TPC) reduced by 1.9 log Colony Forming Unit (CFU)/g. Comparative to distilled water treated and non treated sample, EW-treated sample did not show significant changes in color, off-flavor, freshness and overall acceptability. In addition, residual chlorine in mixed fresh-cut vegetables after treatment with EW was approximately 2.3mg/g. Therefore, the use of EW for decontamination of mixed fresh-cut vegetables was recommended to be an effective method of controlling microflora during storage and distribution for food safety.View full abstractDownload PDF (1322K) -

JOURNAL FREE ACCESSThe feasibility study on rapid and precise quality evaluation of film packaging fresh pork loin was performed by near infrared (NIR) spectroscopy with interactance probe. NIR spectra were acquired in short wavelength region (700-1100nm) at 5 measuring points of each sliced pork loin packed by low density polyethylene bag. The raw spectra and 2nd derivative spectra of each point were analyzed by partial least square regression (PLSR) method. Correlation coefficients (R) between values of intramuscular fat (IMF) by chemical analysis and predicted them were from 0.91 to 0.96 and SEP were from 0.73 to 0.80% according to each one-point spectra. Moreover, high R (R=0.97-0.98) and low SEP (SEP=0.59%) were obtained using the average raw spectra and 2nd derivative spectra of 5 measuring points. On the other hand, values of R (R=0.97) and SEP (SEP=0.56-0.58%) of PLSR result using average spectra of 3 measuring points that are nearly parallel to backfat including the central point of pork loin were almost similar to those of 5 measuring points.
The possibility of rapid and precise evaluation of IMF content of sliced pork loin packed by low density polyethylene bag using near infrared (NIR) spectroscopy with interactance probe was clarified.View full abstractDownload PDF (2460K) -

JOURNAL FREE ACCESSTyphoon 0314 attacked Miyako Island on September 10-11, 2003. The maximum instantaneous wind speed of 74.1m/s was recorded and this is in the seventh place in the records observed in Japan. The authors investigated the commercial greenhouses damaged by the typhoon in sixteen locations. The damages were categorized into 1) cracked the concrete foundation, 2) breaking of end plate where base of column, 3) the beam and the doorjamb tied with the joint and bolt was broken and dropped, and 4) broken weld zone. These damages caused by the strong winds have not been reported in the past in Okinawa. The collapse patterns of the greenhouses covered with only insect screens were similar to other greenhouses and the bases on the windward gable end were pulled out. Analysis showed that it was caused by the weak resistance against the wind forces acting on the bases to be pulled upward and the bases could be pulled out at a wind speed of 46.4m/s or higher. Moreover, the weld zone of eaves of a square steel pipe plastic house was fractured. Analysis showed that it was caused receiving the wind load of 37.5m/s or higher on the side.View full abstractDownload PDF (10316K) -

JOURNAL FREE ACCESSThe purposes of this study were to reveal the environmental impacts on livestock manure treatment systems at pig-fattening. It was evaluated by life cycle inventory analysis and impact assessment.
The composting had impacts of global warming and acidification. It was assessed that the global warming impact from composting were influenced by gas emissions from energy consumption as much as CH4. N2O from treated manure. The liquid composting system and purification had impacts of global warming more than manure composting. It was caused by N2O from N of liquid contents. Especially, it revealed that NH3 emission has impacted acidification at the liquid composting and drainage has impacted eutrophication at the purification. The impact of global warming from methane fermentation was the lowest in these treatment systems. It was about 20% of other systems global warming impact. It was considered the effect of closed system with anaerobic fermentation. But, it had impact of acidification by NH3 emissions from opened storage tank for digested slurry.
Therefore, it was revealed by the comparison of environmental impact with LCI analysis on manure treatment systems that the characteristics of environmental impacts, and it indicated that each system has environmental impacts for variant impact category.View full abstractDownload PDF (1755K)
