The role of biotechnology in agricultural production and food supply. El papel de la biotecnología en la producción agrícola y en el abastecimiento de alimentos. Centro, Tlahuelilpan Hidalgo, México. Campus la Concepción Km 2. San Juan Tilcuautla. San Agustín Tlaxiaca. Hidalgo, México. Cano, D. Díaz and C. Over the past several decades, technological developments and modernization have grown concomitantly. For what is treatment effect in research, advances in biotechnology have been used as a tool to increase food production.
Specifically, advances in genetic engineering have made possible the manipulation of crops to increase yield, guaranteeing food supplies for the increasing world population. However, transgenic crops have not been well received by all members of society, and there is still uncertainty about their social benefits and the possible implications to human health. Additionally, the benefits of agricultural modernization have favored only developed countries, whereas people living in developing and underdeveloped countries suffer rampant hunger, malnutrition and poverty.
Produdtion, there is a necessity to create policies guaranteeing that the advances in biotechnology are translated into better agricultural practices that can meet the ever-growing food demand. The agricultural modernization process, however, must consider that sustainable development is imperative in modern societies and that there is an increasing desire for consuming so-called organic foods based on the idea that these foods have a higher quality and stimulate regional agricultural production.
This review discusses the role of biotechnology throughout history in relation to agricultural production and the development of the food sector. Key words: Agriculture, development, food industry, nutrition, organic food, transgenic food. Díaz y C. Gracias a los avances en ingeniería genética ha sido posible manipular cultivos y así, poder garantizar el abasto de alimentos entre la población.
Sin embargo, estos alimentos biotechnologh han sido del todo bien recibido por la sociedad, pues todavía existe incertidumbre en torno a sus beneficios tanto a nivel social como a nivel de la salud de los seres humanos. En países en vías de desarrollo, todavía se observa pobreza, hambre y desnutrición. Por lo tanto, es necesario crear políticas que fomenten la producción y así poder cumplir con la demanda de alimentos que cada día es mayor. En esta revisión se discute el papel que ha tenido la biotecnología en diferentes épocas de la historia para la producción agricola y el desarrollo del sector alimentario.
The increase in human population what is the importance of biotechnology in food production has become a major threat to food security. In this respect, efforts of biotechnology have been concentrated on biotevhnology technologies that can increase crop yields. Although biotechnology applications can be traced to BC, it was in procuction s when the development of genetic tools and cellular and tissue engineering gave the biotechnology field new momentum that allowed a range of possible novel applications Awais et al.
The increasing recognition of biotechnology as an economic and social growth factor has stimulated governments in several countries to provide financial support to their local biotechnology companies to foster research, development, and commercialization of ideas and products Awais et al. One remarkable example of biotechnology innovation is the production of genetically modified GM crops aimed at insect and weed control that result in increased crop yields Dash et al.
Despite the great biotechnological advances in agricultural production achieved over the past 50 years, the efforts to mitigate poverty and inequality have proven to be insufficient, mostly in rural areas. Food safety is handled by different approaches in different regions and social strata FAO,and in fully developed countries, there still are people suffering from starvation and illnesses linked to it.
Considering the advances in technology, hunger has been translated into an avoidable harm that must not be forgotten. In the past decade, consumer behavior concerning food products has been influenced by quality and safety Boccia and Sarnachiaro, Currently, highly processed foods with a high content of chemical products are not accepted among the population, and there is a clear tendency towards consuming fresh food. However, GM crops have become the center of debate due to the discrepancy of opinions that arise around the repercussions that the consumption of these types of food may have on human health.
This review describes the biotechnological advances at different periods of history and how their efforts have concentrated what is the importance of biotechnology in food production trying to mitigate the shortage of food supply and associated malnutrition. This review analyzes current trends towards healthier food consumption and its sustainable development. The goal of this review is to discuss the controversy around the application of these biotechnological tools for prlduction agricultural production.
Biotechnological development of agriculture. Agriculture has been the backbone of the human food supply directly and indirectly. However, agricultural land is limited, and it has decreased over time due to the increasing world population. Therefore, global agricultural productivity must increase in order to meet what does the term causation mean in law increasing food demands FAO, Agriculture is considered one of the oldest activities practiced by human-kind.
In the beginning, agriculture was manually practiced; later, primitive technologies based on the use of the plow and the harrow what does access to local network mean an increase in agricultural productivity. The Industrial Revolution, which spanned from toenabled an accelerated economic development that became strategic for what is composition in art explain growth of countries FAO,which in turn triggered the migration of people from rural areas to industrialized cities.
To increase agricultural production and meet consumer and producer needs, the use of ijportance on farms was imperative, progressing through remarkable improvements. The introduction of chemical fertilizers around the same period of time enabled crop protection against disease and attainment of higher importnace. One of the first chemicals employed was nitrogen what are 7 signs of a healthy relationship, although its use was restricted due to high costs.
In England, agriculture became a science by performing novel experiments impoftance at improving agricultural methods Cubero,which eventually led to important innovations such as crop rotation and new discoveries such as the ability of some legumes to convert atmospheric nitrogen to nitrates Overton, One of the earliest records of plant hybrids was the report by Cotton Mather in The next important documentation regarding the development of plant hybridization was provided by quarter in In fact, crosses for both floral morphology peoduction hybrid vigor were greatly expanded by many researchers during the next year Teranishi, Inplants genetics allowed obtaining plant species that were what is the importance of biotechnology in food production productive and exhibited resistance to some pests.
Ina new movement changed farming: The Green Revolution, which is a term used for the rapid increase in food production, especially in underdeveloped and developing nations, via the introduction of high-yield bjotechnology varieties and the application of modern agricultural techniques FAO, The Green Revolution arose as the technological response to a worldwide food short-age, which became threatening in the period after World War II.
The technologies developed during this period, which usually involve bioengineered seed that worked in conjunction with chemical fertilizers and heavy irrigation,had a huge impact on three main cereals maize, wheat and rice. A particularly important finding was the discovery how the biological molecule of DNA was responsible for inheritance.
In the s, the genetic code was cracked, and subsequent studies began the transfer of genetic material from one organism to another by genetic engineering techniques Dash et al. The intersection between genetic engineering and biotechnology was the main factor in the creation of what is the importance of biotechnology in food production modified organisms GMOs Table 1. Table 1.
Summary of the main events in the development of biotechnology. At this institute, Mexicans and foreign researchers worked together for the genetic improvement of crops and produced exceptional results: in just two decades, wheat productivity increased from kg ha -1 in to kg ha -1 in Ceccon, However, one limitation regarding basic and applied agrarian research is that it usually is carried out in developed countries biotcehnology specified climate conditions, and innovations and improvements in crop yield can only be obtained in similar conditions.
For this reason, it was necessary to adapt the new technologies and discoveries to warmer or more arid climates that prevail in underdeveloped countries. One of the first genetically engineered crops worldwide was soybean MON, produced under the brand name Itancawhich expressed the crystal insecticide protein CytAc1derived from Bacillus thuringiensis Bt toxin that provided protection against feeding damage caused by some lepidopteran pests EFSA, GM soybean has made rapid strides in recent decades, and its cultivation area has been what is graph of a linear equation yearly.
Currently, genetic modification has been successful in maize, tomato, rice and cotton plantations Sanahuja et al; Tabashnik et al, mainly by inserting exogenous genes transgene that encode a protein that is toxic to specific pests. It has been observed that some microorganisms, including plant growth-promoting bacteria, wjat and cyanobacteria, have shown biofertilizer-like activities in the agricultural sector Mahanty et al. The utilization of microbes as biofertilizers is currently being considered, to some extent, as an alternative to chemical fertilizers to enhance crop production.
The use of nanotechnology can boost agricultural production, and it is becoming ij of the most important tools in modern agriculture. Nanotechnology provides new agrochemical agents and new delivery mechanisms to improve crop productivity, and it promises to reduce pesticide use through nanoformulations of agrochemicals.
Biotechnological development of food. For years, biotechnology has been employed in the food sector through the production of additives and ingredients as well as the development of more efficient and less costly operations for the production of food. In addition, biotechnological interventions have been focused on modifying or enhancing taste, miportance, shelf-life, texture and nutritional value of food products, employing fermentation, enzyme technology, nanotechnology and molecular biology.
It was bioyechnology that technology would become a tool that would help solve the problems of the worldwide supply of food. However, this has not occurred. Nonetheless, it is convenient to note the great achievements that were carried out thanks to the discovery of microorganisms and the development of biological, biochemical and molecular techniques that allowed the progress of this branch of science Table 1.
In andIx Pasteur discovered the microbiology of lactic fermentation and the function of yeast in alcoholic fermentation. These types of fermentations continue to be the most popular process what is the definition of abusive relationship obtaining food to date Madigan, These processes can be carried out naturally, such as cocoa fermentation.
It is likewise un to employ inocula to obtain foods such as yogurt and cheese. Fermentation can occur in pre-established cultivation media as in the production of beer, in the production of primary metabolites alcohol and organic acids and in the production of secondary metabolites enzymes and polysaccharides. Currently, fermentation is still a very useful what is the importance of biotechnology in food production for food processing. Fermented food from different sources such as milk, cereal, fruits, vegetables and meat have contributed a great deal to the livelihood of rural and urban people.
The organisms involved in fermentation continue being objects of studies. One example is how lactic acid bacteria could fulfill the novel role of efficient cell factories for the production of functional biomolecules and food ingredients to enhance the quality of cereal-based beverages Waters et al. Enzymatic technology has been a tool used for food biotechnology because it has helped optimize and accelerate bioprocesses.
In teh food-processing sectors, such as baking, juice processing, starch, dairy and other related industries, enzyme play a crucial role as biocatalysts in the biotransformations process Dash et al. A large number of enzymes are used in the food industry. For example, in the bakery industry, proteases act on the protein of biootechnology flour, reducing the gluten elasticity and therefore reducing the shrinkage of dough.
In the foov industry, rennet has been used since ffood times to help the clotting of milk in obtaining cheese. The use of lactase for the production of low-lactose milk is another important dairy application. The use of the enzymes such as cellulose and pectinases in the manufacture of fruit juice can give better juice yield with high quality. In addition, papain and bromelin are proteases used as meat softeners. Conventional food processing techniques are well developed, but processing often leads to lowered nutritional value Nakitto et al.
Biofortification is the application of biotechnology to fortify with external supplementations, and biofortification has seen new approaches, such as injection of vitamin D into bread and milk to overcome deficiencies. The birth of classical genetics was another milestone in the development of biotechnology with the experiments developed by Mendel. The production of nectarines, apples with pear flavor and other types of hybrids has occurred, and these products have been accepted by consumers.
In the middle of the twentieth, the development of biotechnology accelerated thanks to the scientific discoveries that gave rise to genetic engineering.
