Agronomy Journal Abstract - Breakage Susceptibility of Corn Kernels in Relation to Crop Management under Long Growing Season Conditions
Physical factors are other quality attributes that are neither grading factors nor chemical composition. Physical factors include stress cracks, kernel weight, kernel volume and true density, percent whole kernels, and percent horneous (hard) endosperm. Tests for these physical factors provide ...

Abstract. The tendency of corn (Zea mays L.) kernels to break during post-harvest handling causes problems for several user groups.Crop management factors have been reported to influence breakage susceptibility, but the effects of hybrid, plant density, harvest moisture content, and drying temperature on grain corn breakage susceptibility …

One hundred fifteen hybrids were evaluated from the 2006 to 2008 harvests. Measurements of kernel hardness, water adsorption, kernel size and dimensional characteristics, pericarp thickness, chemical composition (starch, fat and protein), bulk density and equilibrium moisture relationships were completed.

corn, popcorn, flour corn, dent corn, and sweet corn (Watson, 1987a). Different types of corn have different proportions of horny and floury endosperm. The floury endosperm is softer and easier to break than the horny endosperm. Different parts of corn have different physical and chemical proper-ties.
Properties of grain quality. Overall quality of grain is affected by several factors includes, growing practices, time and type of harvesting, postharvest handling, storage management and transportation practices.

The percentage of floaters, an index of kernel hardness, varied significantly among genotypes, but was not correlated with breakage susceptibility for low-temperature dried corn. Test weight decreased and 100-kernel dry matter weight increased as the percentage of floaters increased.
Stenvert tester to determine hardness of corn (Pomeranz et al. 1985a) and hardness of eight commercially dried corn hybrids equilibrated at two moisture levels (Pomeranz et al., 1985b). In a more recent study (Pomeranz et al., 1985c), kernels from seven classes separated according to size and shape from three hybrids were ground on the Stenvert …
PHYSICAL CHARACTERISTICS OF CORN KERNELS AS ... characteristics influenced the effect of N fertilization on kernel hardness and breakage susceptibility.
Kernel hardness index (Wichser 1961) is based on percentage offloating kernels and moisture content. Breakage susceptibility tests were run with the Stein breakage tester, model CK2, on 100-g portions of corn with 2-minimpact. Breakage was deter mined as percentage of sample passing through a 0.48-cm(121 64-in.) round hole perforated sieve.
Drying High Moisture Corn – Challenges of the 2009 Harvest Season ... Hard. Drying System ... Breakage Susceptibility
High kernel temperatures reduce dry matter in feed grains, increase the amount of stress cracking and breakage susceptibility, reduce the yield of grits during dry milling and of starch during wet milling, diminish the yield and quality of oil from oilseeds, and destroy the germination value in seed grain.

of the kernel dries more rapidly than the moisture transfers from within the kernel to the surface. Stopping drying at higher corn moisture contents can reduce the amount of stress cracks and breakage susceptibility. In addition, some of the breakage potential is developed during rapid cooling in the high-temperature dryer.
Corn-based snack foods, such as corn and tortilla chips, represent one of the fastest growing segments of the nearly 10 billion dollar salty snack food market. White corn products are in particularly high demand. Before grinding corn into masa needed for chip production, each kernel’s hull must be removed during the cooling, soaking, and …

Breakage Susceptibility and Hardness of Corn Kernels of Various Sizes and Shapes C. R. Martin, H. H. Converse, Z. Czuchajowska, F. S. Lai, Y. Pomeranz
Breakage susceptibility and hardness of three yellow dent corn hybrids were determined for kernels separated into 6 size and shape categories and equilibrated to 12. 3 and 14. 7% moisture (wet basis). Mechanical breakage at harvest was influenced more by kernel size, shape and structure characteristics than by kernel hardness properties.
BREAKAGE SUSCEPTIBILITY OF CORN OF DIFFERENT STRESS-CRACK CATEGORIES S. Gunasekaran, K. Muthukumarappan MEMBER ASAE ABSTRACT. Breakage susceptibility (BS) of different kernel stress-crack categories (single, double, and multiple) were tested for two varieties of corn using the Wisconsin and Stein …

BREAKAGE susceptibility and hardness of three yellow dent corn hybrids were determined for kernels separated into 6 size and shape categories and equilibrated to 12.3 and 14.7% moisture (wet basis).
Pomeranz et al (1984) looked at corn hardness as measured by density and near-infrared reflectance; Stroshine et al (1986) measured density and breakage susceptibility ofselected hybrids; and Kirleis and Stroshine (1990) checked the effect of hardness on corn breakage susceptibility and dry-millingresponse.
and back to 15.5% or 20% moisture may make corn kernels susceptible to breakage and thereby incur a discount at the time of marketing. Also, in grain trading, farmers often blend dry corn with a moisture content lower than 15.5% with wetter corn to get the blend at 15-5% moisture content prior to marketing.
Jindal and Mohsenin (1978) used three methods of analysis for the determination of the dynamic hardness of corn kernels as a function of moisture content. The objective of the present study was the development of improved hardness measuring instruments and their application to corn hardness evaluation.
