Detection of stress cracks in corn kernels using machine vision
Maintaining high quality of corn is very important to both corn producers and buyers. The detection of stress cracks remains one of the most important tasks in corn quality inspection. Such an index of quality would be helpful in assessing not only the end-use values of the corn but also the drying …

Automated corn kernel quality inspection using machine vision
… and developed for automatically inspecting corn kernels. This system consisted of a motor driven kernel delivery apparatus, two light-beam-based object position sensors, a strobe light, a control circuit, a video camera and a PC computer with image processing hardware and software.

Measurement of transient moisture profiles and structural changes during the drying and cooling of maize using MRI
… drying and cooling processes. Three yellow dent corn hybrids were measured during drying and cooling. Four drying temperatures, 27, 49, 71, and 93$\sp\circ$C, were used. Magnetic resonance imaging (MRI) was applied to nondestructively acquire proton images from the corn kernels during drying and …

Computer vision based corn kernel quality evaluation: Traditional versus machine learning
Corn kernel quality evaluation is a trivial task for experienced farmers and agriculture researchers, but it becomes tricky if we try to develop a computer vision based automatic solution. In this thesis, we present two approaches for this problem, briefly introduce the data sets corresponding to …

Behavioral and Physiological Aspects of Self-Selection by the Corn Earworm, Heliothis Zea
Larvae of the corn earworm, Heliothis zea (Boddie) (Lepidoptera: Noctuidae), prefer to feed on corn silks as early instars but change their feeding preference to corn kernels as they mature. Within the corn kernel, final instar larvae prefer to feed on germ but will always eat some of the …

Effects of drying and heating conditions on protein denaturation, starch damage and protease activity of corn: Its relationship to wet millability
Laboratory heated and dried yellow dent corn was investigated in three parts for this study. The first part determined the effects of moisture content, heating time, and temperature on starch damage (gelatinization) and protein denaturation of individual corn kernels. For different genotypes, …

Using single corn kernel classification, pooling, and simulation to address skewness and clustering in aflatoxin distribution
Aflatoxin contamination in corn has posed a serious health risk to consumers. To detect aflatoxin contamination in a lot, one may adopt the bulk sampling approach to estimate the overall aflatoxin concentration in the lot, compare it against the aflatoxin action level, and decide whether to accept …

Comparison of fermentation characteristics between colored corn and yellow dent corn using two dry grind process methods
… dry grind process is needed. One way is to use corn rich in anthocyanin content as feedstock. Anthocyanin imparts red, blue and purple color to corn kernels. Anthocyanin could also affect yeast during fermentation. The objective of this study was to evaluate the performance of anthocyanin rich …

Evaluation of aflatoxin-related products from ozonated corn
… the ozonation process in degrading aflatoxin in corn, and investigated the chemical reaction between aflatoxin and gaseous ozone. Ozonation (12-13 wt%) totally degraded aflatoxin B1 in a model system. Conversion of aflatoxin into polar compounds was observed during ozonolysis of 100 µg aflatoxin …

Investigation of methods for reducing aflatoxin contamination in distillers grains
… of reduction of aflatoxin in the incoming corn prior to bioprocessing, the degradation of aflatoxin in the intermediate products, namely DWG and CDS, during processing, and aflatoxin degradation in the DDGS. Segregation techniques (size screening and density sorting) and detoxification …

Chemical characterization of proanthocyanidins in purple, blue, and red corn after different milling processes and their anti-inflammatory properties
… compare the PA profiles of purple, blue, and red corn kernels after dry milling, wet milling, and dry grind processing, and to determine the anti-inflammatory features of PAs extracted from colored corn. Among purple, blue, and red corn, purple had the highest PA concentrations. In purple corn, …

Developing a spectroscopy-based high throughput assay for anthocyanin content in corn
… detecting and estimating anthocyanins in whole corn kernels and in ground corn. Results of the study showed that L*a*b* measurements were not useful for predicting TAC of whole corn samples, despite having multiple linear regression (MLR) models with 0.60 > R2 > 0.70. The poor predictive …

Evaluation and modification of processing techniques for recovery of anthocyanins from colored corn
… residues. The potential of using colored corn as a viable source of anthocyanins was explored. Anthocyanins containing purple and blue corn were fractionated using laboratory scale wet milling, dry milling and dry grind processes; coproduct yields were compared with those from conventional …

Identifying candidate genes/loci influencing barley secondary cell wall properties
… the plant normally used as food (e.g. grain and corn kernels). This means that second generation production can co-exist with food production, reducing the amount of waste produced and increasing the net energy gain from the crop and inputs. Currently, commercial adoption is low as the production …

Food safety through fungal disease and mycotoxin mitigation on dairy farms: From field to feed and the rumen
… such challenge common for cows fed whole-plant corn silage (WPCS) is the often negative effect of fungi. Fungi affect WPCS both in the field and post-harvest; and can cause serious issues for cows that consume it. The use of fungicide (FUN) in the field and feeding adsorbents (AD) to cows are …

Heterosis in compositional, physical, and wet-milling characteristics of hybrids from exotic introgressed by adapted inbred lines in corn
<p>Corn (Zea Mays L.) is one of the most important cereal crops in the world and the main crop in the United States. Starch is the most abundant component of the corn kernels and the most valuable fraction recovered by wet milling of corn. The amount wet milled from a sample is an indication of the …
