Of the tradi- tional products of the industry—corn starch, sweeteners, oil and feedstuffs—starch has been the leader in industrial applications. In several industrial sectors, the use of starch is well established, but development of new uses and the extension of existing applications continue. Applications for sweeteners are rooted in food manufacturing, but advances in processing technology have opened several opportunities. By exploring the uses of starch in the established sectors of paper, adhesives and textiles, we hope to convey a better understanding of how starch can advance the production process. The review is also intended to provide an appreciation for product characteristics attributable to starch. An examination of the current and potential industrial markets for corn starch and corn-derived Charles F. Conner chemicals shows promising growth for the corn wet milling industry. This market analysis is President intended to provide insight to the dynamic of the relationship between supplier and consumer Corn Refiners as well as identify the factors that will influence growth. -
Corn Has Diverse Uses and Can Be Transformed Into Varied Products
Maize Based Products Compiled and Edited by Dr Shruti Sethi, Principal Scientist & Dr. S. K. Jha, Principal Scientist & Professor Division of Food Science and Postharvest Technology ICAR-Indian Agricultural Research Institute, Pusa New Delhi 110012 Maize is also known as Corn or Makka in Hindi. It is one of the most versatile crops having adaptability under varied agro-climatic conditions. Globally, it is known as queen of cereals due to its highest genetic yield potential among the cereals. In India, Maize is grown throughout the year. It is predominantly a kharif crop with 85 per cent of the area under cultivation in the season. The United States of America (USA) is the largest producer of maize contributing about 36% of the total production. Production of maize ranks third in the country after rice and wheat. About 26 million tonnes corn was produced in 2016-17 from 9.6 Mha area. The country exported 3,70,066.11 MT of maize to the world for the worth of Rs. 1,019.29 crores/ 142.76 USD Millions in 2019-20. Major export destinations included Nepal, Bangladesh Pr, Myanmar, Pakistan Ir, Bhutan The corn kernel has highest energy density (365 kcal/100 g) among the cereals and also contains vitamins namely, vitamin B1 (thiamine), B2 (niacin), B3 (riboflavin), B5 (pantothenic acid) and B6. Although maize kernels contain many macro and micronutrients necessary for human metabolic needs, normal corn is inherently deficient in two essential amino acids, viz lysine and tryptophan. Maize is staple food for human being and quality feed for animals. -
Identification of Valuable Corn Quality Traits for Starch Production
Identification of Valuable Corn Quality Traits for Starch Production By: Lawrence A. Johnson Center for Crops Utilization Research Food Science and Human Nutrition C. Phillip Baumel Economics Connie L. Hardy Center for Crops Utilization Research Pamela J. White Food Science and Human Nutrition A project of the Iowa Grain Quality Initiative Traits Task Team Funded by the Iowa Corn Promotion Board 306 West Towers 1200 35th St. West Des Moines, IA 50266 October 1999 Center for Crops Utilization Research Iowa Agriculture & Home Economics Experiment Station Iowa State University, Ames, IA 2 Acknowledgment This report is intended to provoke discussion and debate that will lead to a vision among researchers in public institutions, seed companies, and the starch processing and food industries for modifying corn traits for starch (and other complex carbohydrates) production to enhance utilization and profitability of growing corn. The report attempts to provide direction to farmer organizations and to the corn industry about potential targets for investing research funds. One should recognize that some of the modifications considered required speculation about functional properties and potential applications. Additional research on the relationship between the structures of starch and other complex carbohydrates and functionality in food and industrial applications may refute some of that speculation.

The morphology of native, control, and AS-modified waxy corn starches (230 and 460 U) was examined using a particle size analyzer and field-emission scanning electron microscopy (FE-SEM). AS modification of the starch elongated the glucose and resulted in higher SDS and RS contents. The mean particle sizes of the control, 230 U-AS-, and 460 U-AS-treated starches were 56.6 µm, 128.0 µm, and 176.5 µm, respectively. The surface of the 460 U-AS-treated starch was entirely porous and coral-like, while the 230 U-AS-treated starch had a partial dense and flat surface which did not react with AS. FE-SEM of the granule cross section confirmed that the center contained a dense and flat region without any evidence of AS reaction to either of the AS-treated starches. It was assumed that the particle size and porous and sponge-like particle features might be related to the SDS and RS fractions. Keywords: amylosucrase-modified starch; particle size distribution; cross-sectioned particle; morphology; low glycemic starch 1. -

In this study, the gelatinization of waxy corn starch (WCS) was investigated with the goal of providing an option for the rapid determination of starch gelatinization characteristics. The procedure used in the study was solely based on differential scanning calorimetry (DSC), which is an established technique for the determination of thermal characteristics of starches. A sequence of experiments was conducted to determine the excess water condition, an estimate of the minimum gelatinization temperature, and gelatinization time. These parameters were found to be 65 wt.% water, 75–85 C, and 10 min, respectively. The estimation ≥ ◦ of the minimum gelatinization temperature was determined from the thermal properties of the WCS as obtained by DSC. -
Corn Grain Processing and Digestion
CORN GRAIN PROCESSING AND DIGESTION Fred Owens Pioneer Hi-Bred International, Inc., Johnston, IA SUMMARY Grains are fed to livestock primarily to supply energy, and the major energy source in cereal grains is starch. For maximum starch digestion, corn and sorghum grain must be processed. For non-ruminants, starch from finely ground grain is fully digested, but for ruminants fed concentrate diets, finely ground grain can cause metabolic diseases. Hence, steam rolling or flaking and fermentation (high moisture storage) rather than fine grinding are used for grains fed to ruminants to increase the extent of starch digestion. Such processing methods increase starch digestion both in the rumen (of dietary starch) and postruminally (of starch reaching the small intestine). The lower the density of corn flakes, the greater the digestibility of starch, particularly in the small intestine. For maximum ruminal starch digestion, a thinner flake is needed for lactating cows than for feedlot cattle because particles spend less time in the rumen for digestion in lactating cows than in feedlot cattle. This shortened ruminal residence time can explain why ruminal and total tract starch digestibility is lower for lactating cows than for finishing cattle. Contrary to popular belief, digestion of starch reaching the small intestine does not decrease as abomasal supply of starch increases. However, neither dry rolled or whole corn is digested well post-ruminally. Due to reduced loss of methane and heat, available energy supply for the animal is greater for starch digested in the small intestine than for starch fermented in either the rumen or large intestine. Different hybrid characteristics are desired for different processing methods. -
Maize Seed Industry in Thailand
WORKING PAPER 04 | NOVEMBER 2014 Maize Seed Industry in Thailand DEVELOPMENT, CURRENT SITUATION, AND PROSPECTS Orachos Napasintuwong and ABSTRACT The seed industry in Thailand is among the advanced and well-developed industries in Asia. Maize contributes to the larg- est share of seed production and trade. The government and international organizations contributed significantly to the success of the maize seed industry in Thailand by building infrastructure for research and promoting the role of the private sector in the industry during the early years. The private sector also added to the industry’s rapid expansion through con- stant and heavy investment in research and development. Thailand’s goal of becoming a seed hub center in this region is bolstered by its suitable geography and weather, numerous highly trained plant scientists, wide diversity of germplasm, and membership in the Association of Southeast Asian Nations (ASEAN) Economic Community (AEC), which will come into effect at the end of 2015. Despite promising motivations, domestic regulations could be prohibitive factors in Thailand’s becoming competitive in the regional seed market. This paper provides the history of development; an analysis of the cur- rent industry’s structure, conduct, and performance; and a review of related regulations of the maize seed industry in Thai- land. The lessons learned from the success of the maize seed industry in Thailand could provide implications for the devel- opment of the seed industry in other developing countries. Keywords: seed, privatization, intellectual property rights, IPR, genetically modified INTRODUCTION The seed industry in Thailand is among the advanced and well-developed industries in Asia. -
