In order to prolong the shelf life of fresh millet-wheat noodles (FMNs) stored at 25°C, different doses (0, 1, 3, 5, 7, and 9 kGy) of electron beam irradiation (EBI) were applied to millet-wheat mixed flour to decrease initial total plate count. Total plate count of mixed flour and shelf life, textural properties, cooking qualities, volatile compounds, and water characteristics of FMNs were determined. The results showed that EBI treatment significantly reduced total plate count. Doses of 7 and 9 kGy had a complete bactericidal effect on mixed flour, but such doses significantly decreased the textural and cooking quality with more off-flavor compounds. The 5 kGy treatment maintained better textural and cooking quality with fewer off-flavor compounds, and it was a suitable dose that had the same effect on prolonging shelf life of FMNs to 44 hr as 7 and 9 kGy treatments. Novelty impact statement• Electron beam irradiation treatment had a significant bactericidal effect on milletwheat mixed flour.• Irradiation doses larger than 7 kGy significantly reduced the cooking quality and textural property.• The 5 kGy treatment was suitable for irradiation treatment of millet-wheat mixed flour.

Soybean physical and chemical properties changed by size (from 4.8 to 8.8 mm diameter), but soybean size and seed density did not affect the protein and oil determination accuracy of three near-infrared transmission analyzers. Corn samples were also separated by size and kernel density. Changes in corn kernel density and size introduced small errors in near-infrared transmission protein, oil, and starch measurements. In corn protein, the maximum error was about ±0.2% points. A robust calibration set is needed to eliminate the weak seed weight and density effects, as well as to support the corn density calibration for near-infrared analyzers.

“…After 10 days, the beans were assumed to be at equilibrium. Oven moistures of three whole-grain samples, approximately 10 g each, were averaged to obtain the moisture content of the subsample (Hartwig and Hurburgh, 1989). The final range of moistures is shown in Table 2.…”

“…Each bean was weighed to the nearest 0.0001 g, and its spectral absorbance was immediately recorded. The bean was then dried in an air-oven at 130° C (266° F) for 3 h and (Hartwig and Hurburgh, 1989). The 601-point spectral curves were smoothed by using a 5-point (1 nm gap width) moving average to reduce the influence of noise in the spectra: plane separating the cotyledons was used to estimate the optical pathlength (t).…”

A calibration set of 140 soybeans from seven different varieties, ranging in moisture from 5 to 22%, wet basis, was used to calibrate a spectrophotometer for predicting moisture of single soybean seeds. Near-infrared absorbance (A) of individual soybean seeds was measured over the spectral region from 800 to 1100 nm by 0.5 nm increments. The axis of the soybean seed parallel to the incident light beam was measured as an estimate of optical pathlength. Three mathematical techniques were used to develop calibration equations: linear correlation with a difference in absorbance (AA), stepwise multiple linear regression (MLR), and partial least squares (PLS). A validation set contained 100 soybeans from 5 different varieties, ranging in moisture from 5 to 20%, wet basis. The standard error of prediction (SEP) for equations using absorbance data only was 0.88% for AA, 0.82% for MLR, and 0.81% for PLS. The SEP for equations using pathlength and absorbance data was 0.73% for AA, 0.69% for MLR, and 0.65% for PLS.
