Maize is a globally important crop mainly utilized as feed, food and raw material for diverse industrial applications. Among cereals, it occupies third place after rice and wheat and is a staple food for a large segment of population worldwide particularly in the Asian as well as African countries. This monogram discusses various aspects of nutritional quality of maize such as quality protein maize which has been considered as most significant discovery in enhancing nutritional quality of cereals in terms of increasing the concentration of essential amino acids. The biochemistry of starch which is an important industrial product of maize has been discussed in detail. Further, the role of maize oil which is highly regarded for human consumption as it reduces the blood cholesterol concentration has also been elaborated. Naturally, maize is a rich source of carotenoids such as beta-carotene, zeaxanthin, lutein, cryptoxanthin which have highly diverse health benefits ranging from maintaining normal vision to lowering of oxidative stress. The need for biofortification of maize for provitamin A carotenoids and their role in alleviating vision impairments have also been discussed. The effect of various biotic and abiotic stresses particularly carbon dioxide and temperature on quality has been discussed thoroughly. Many value-added products as well as fermented foods that have been produced from maize which is consumed in different forms worldwide are also discussed. The aspects related to the maize application as fodder and as a source of malting have also been covered concisely. Overall, the book provides complete information about various quality aspects of maize. The various stakeholders such as maize researchers, extension specialists, students, teachers as well as farmers will be immensely benefitted from this monogram.

This compelling book exploresthe intimate connections between people and plants, agriculture and cooking, and the practical work of building local food networks and transnational social movements. Lauren E. Baker uses corn and maize to consider central debates about food security and food sovereignty, biodiversity and biotechnology, culture and nature, as well as globalization and local responses, in Mexico and beyond. For the author, corn symbolizes the commoditization of agriculture and the cultural, spiritual, ecological and economic separation of people from growing, cooking, and sharing food. Conversely, maize represents emerging food movements that address contemporary health, environmental, and economic imperatives while rooted in agricultural and culinary traditions. The meeting of corn and maize reveals the challenge of, and possibilities for, reclaiming food from its commodity status in the global context of financial turmoil, food crises, and climate change.

The Maize Handbook represents the collective efforts of the maize research community to enumerate the key steps of standard procedures and to disseminate these protocols for the common good. Although the material in this volume is drawn from experience with maize, many of the procedures, protocols, and descriptions are applicable to other higher plants, particularly to other grasses. The power and resolution of experiments with maize depend on the wide range of specialized genetic techniques and marked stocks; these materials are available today as the culmination of nearly 100 years of genetic research. A major goal of this volume is to introduce this genetical legacy and to highlight current stock construction programs that will soon benefit our work, e. g. high-density RFLP maps, deletion stocks, etc. Both stock construction and maintenance are relatively straightforward in maize as a result of the ease of crossing and the longevity of stored seeds. Crossing is facilitated by the separate staminate (tassel) and pistillate (ear) flowers, a feature almost unique to maize. On the other hand, many of the genetic methodologies utilized with maize, including the precision of record keeping, can be adapted to other plants. Facile communication and a spirit of co-operation have characterized the maize genetics community since its earliest days. Starting in the 1930s, institutions such as annual Maize Genetics Cooperation Newsletter, the Maize Genetics Stock Center, and the annual maize genetics meeting provide continuity to the field.

This research investigates the complex relationship between agrobiodiversity and livelihoods in the Central Highlands of Mexico by studying the everyday lives of four key categories of actors: 1) small-scale commercially-oriented maize producers; 2) agricultural research scientists; 3) agricultural extension agents; and 4) maize populations. This inquiry is prompted by a seeming empirical paradox, according to leading theories of agricultural modernization: populations of genetically-diverse locally-bred varieties of maize, along with the diversity of knowledges and practices that maintain them, persistently dominate the small-scale farms of Mexico, even as these varieties are increasingly rendered obsolete, at least within the dictates of a global commodity market, by the recent economic transformations of agricultural modernization. The country's Central Highland region provides a unique opening for inquiry into these dynamic relationships. It is at once home to some of the world's foremost centers of maize research, which partner with regional and multinational biotechnology companies to aggressively promote the adoption of "modern" scientifically-bred maize varieties, and also to small agrarian communities that consistently and, in many cases, exclusively cultivate maize varieties they have bred themselves. Three major questions have been insufficiently explored in academic research: First, how do those involved in maize production, both directly and indirectly, conceive of and engage agrobiodiversity? Second, how do relationships to agrobiodiversity vary within and across maize-centered livelihoods? Third, how do these relationships shape development institutions, agricultural technologies and practices, and trajectories of agricultural change, and whose purposes do they serve as a result -- i.e., why do certain socioecological relationships emerge and persist? My dissertation research addresses these questions by examining the contradictions of agrobiodiversity and agricultural modernization in Mexico's Central Highlands through the perspectives and practical activities of the four groups, enumerated above, whose lives are implicated in the dynamics taking place. Bringing these perspectives together, I argue that processes of uneven agricultural development in the region are highly negotiated, with actors working from within and without existing social and institutional structures to pursue multiple, overlapping objectives. These tensions have produced a dynamic and contradictory landscape of persistent maize genetic diversity, for which adequate explanations are currently lacking. In this research, I find that maize diversity is persisting in the Amecameca Valley because farmers are maintaining economic diversity. This research also finds that, despite all rhetoric to the contrary, the current agricultural development projects at work in the region are undermining, rather than supporting, smallholder maize producer livelihoods.

In India, maize is becoming third most significant crop. Its significance stems from the fact that it is utilised not only for human food and animal feed, but also for corn starch manufacturing, corn oil production, and the generation of baby corns. Additionally, maize stover, the leaves and stalk of the maize plant, is used for forage, biofuel production, and chemical production. Corn is also processed into a multitude of food and industrial products including:- Ø Corn Starch is a yellow powder made from finely ground, dried corn, while cornstarch is a fine, white powder made from the starchy part of a corn kernel. Ø High fructose corn syrup (HFCS) is a sweetener derived from corn syrup, which is processed from corn. Ø Corn oil contains some healthy components like vitamin E and phytosterols, but overall it's not considered a healthy fat. Ø Corn ethanol is produced from corn biomass and is the main source of ethanol fuel, mandated to be blended with gasoline in the Renewable Fuel Standard. Ø Some strains of corn (Zea mays) are cultivated specifically as popping corns. Ø Dextrose Anhydrous can be used as sweetener in baked goods, candies, gums, dairy products like some ice-creams and frozen yogurts, canned foods, cured meats etc. Ø Maltose is a sugar that tastes less sweet than table sugar. It contains no fructose and is used as a substitute for high-fructose corn syrup. Ø Maltodextrin is a white powder made from corn. To make it, first the starches are cooked, and then acids or enzymes such as heat-stable bacterial alpha-amylase are added to break it down further. Ø Dextrose is the name of a simple sugar made from corn that's chemically identical to glucose, or blood sugar. Ø Sorbitol, or glucitol as it is sometimes called, is a slow-metabolizing sugar alcohol derived from fruits, corn and seaweed. The global maize market is expected to grow at a CAGR of 3.8%. The factors that affect the demand for starch mainly include population growth and industrial development of a country; specifically the food and beverage, textiles, paper and printing, pharmaceuticals and other health and beauty products, and adhesives. The demand for high-fructose corn syrup (HFCS) sweeteners across the country is majorly due to its wide usage in the confectionery, bakery, and beverage industries, especially soft drink manufacturing. Rising health awareness among consumers has resulted into increasing preference for corn oil due to its health benefits. More ethanol production means more demand for corn. According to the most recent statistics released by the U.S. Department of Agriculture, 35%, or 5.25 billion bushels, of the projected 15.062 billion bushels of corn harvested will be processed into ethanol. The book covers a wide range of topics connected to Maize Products, as well as their manufacturing processes. It also includes contact information for machinery suppliers, as well as images of equipments. A complete guide on Maize (Corn) Processing and Manufacture of Maize Products manufacture and entrepreneurship. This book serves as a one-stop shop for everything you need to know about the Maize manufacturing industry, which is ripe with opportunity for manufacturers, merchants, and entrepreneurs. This is the only book that covers Maize (Corn) Processing and Manufacture of Maize Products in depth. From concept through equipment procurement, it is a veritable feast of how-to information.

Maize is one of the world’s highest value crops, with a multibillion dollar annual contribution to agriculture. The great adaptability and high yields available for maize as a food, feed and forage crop have led to its current production on over 140 million hectares worldwide, with acreage continuing to grow at the expense of other crops. In terms of tons of cereal grain produced worldwide, maize has been number one for many years. Moreover, maize is expanding its contribution to non-food uses, including as a major source of ethanol as a fuel additive or fuel alternative in the US. In addition, maize has been at the center of the transgenic plant controversy, serving as the first food crop with released transgenic varieties. By 2008, maize will have its genome sequence released, providing the sequence of the first average-size plant genome (the four plant genomes that are now sequenced come from unusually tiny genomes) and of the most complex genome sequenced from any organism. Among plant science researchers, maize has the second largest and most productive research community, trailing only the Arabidopsis community in scale and significance. At the applied research and commercial improvement levels, maize has no peers in agriculture, and consists of thousands of contributors worthwhile. A comprehensive book on the biology of maize has not been published. The "Handbook of Maize: the Genetics and Genomics" center on the past, present and future of maize as a model for plant science research and crop improvement. The books include brief, focused chapters from the foremost maize experts and feature a succinct collection of informative images representing the maize germplasm collection.

Food historian Cynthia Clampitt pens the epic story of what happened when Mesoamerican farmers bred a nondescript grass into a staff of life so prolific, so protean, that it represents nothing less than one of humankind's greatest achievements. Blending history with expert reportage, she traces the disparate threads that have woven corn into the fabric of our diet, politics, economy, science, and cuisine. At the same time she explores its future as a source of energy and the foundation of seemingly limitless green technologies. The result is a bourbon-to-biofuels portrait of the astonishing plant that sustains the world.

Seasonal analysis of the structure, conduct, and performance (SCP) of markets for staple crops has received relatively little attention in food policy analysis yet it has important implications for food and nutrition security. This study employs a mixed methods approach to analyze the SCP of maize markets in Malawi in the 2018/19 main harvest and lean seasons. We interviewed 749 traders from 74 markets across 8 districts, held 28 focus group discussions (FGD) with a total of 480 farmers and analyzed daily and weekly price data from 13 regional markets. The structure of maize markets was explored by examining marketing channels, barriers to entry and the competitiveness of different tiers of the marketing chain. Inequality in sales revenues, switches in trader types between seasons, quality and weights standardization, and the behavior of traders were used to examine market conduct. Performance was assessed by examining traders’ costs and margins, and the spatial and temporal integration of maize markets. We find that Malawi’s maize market is pyramidal in structure and highly competitive at lower tiers of trade but ‘oligopolistic’ at higher tiers. The market channels vary across seasons with switches between trader types and instances of rural-urban trade reversals. There is considerable inequality of sales revenues among traders of similar capacities, and a widespread lack of structured trading despite existing institutions. A high ratio of marketing costs to revenue suggests marketing inefficiencies. Malawi maize prices were highly seasonal and more volatile than neighboring countries. In contrast to previous studies, our findings show weak spatial integration of markets and slow price adjustments to long-run equilibrium values even among short-distance market pairs. The study highlights five pathways to improving Malawi’s maize marketing system: (1) increased policy predictability to promote private-sector investment; (2) institutionalization of quality grades and standardization of weights and measures; (3) increased commercialization of smallholder maize production; (4) investment in enabling infrastructure; and (5) the promotion of structured trading.
