Food chemistry is the study used to analyze the chemical and biological components in foods for consumer consumption.1 The food substance(s) studied fall into varying categories such as meat, vegetables, liquids, and genetically modified foods(GMO’s). The fabrication of this study relies on the biological components incorporated into the food including vitamins, water content, minerals, enzymes, flavors, colors, fats, and so on. An important methodology to analyzing these biological components is the analytical spectroscopy.2 Spectroscopy is the study of molecular energy and radiation with respect to matter. It analyzes the wavelength of radiation, the relationship between varying ions and nuclei components, and the collision energy of the particles.3 The various spectroscopy types rely on the differing terms of reliability, each with their own advantages and disadvantages. The major points of spectroscopy in food chemistry are Ultra Violet Spectroscopy, Nuclear Magnetic Spectroscopy, Near Infrared Spectroscopy, Positron Annihilation Spectroscopy, Atomic Emission Spectroscopy, and Laser Raman Spectroscopy; each method will be discussed on the basis of uses in food chemistry, how they work, and with the advantages and disadvantages to better understand the most relevant uses in food chemistry for each.
Ultra Violet Spectroscopy is an absorption spectroscopy technique that focuses on the ultraviolet visible spectral region, which uses light in the visible, near-UV, and near-infrared ranges (190-380nm and 380-750nm, respectively).4 The visible range directly influences the observed dye of the compounds involved.5 In this visible region, the molecules undergo electron transitions that are measured in accordance with the excited state...

...ability of testing for multiple elements. Laser Raman Spectroscopy procedure has a detailed chemical/molecular analysis, which is information rich, and contains data relating to the specific chemical structure of the material being analyzed. It can be used to distinguish a material’s elements, and faster identification can be found with the use of spectral databases.39 No ground work is needed for Raman Spectroscopy, and this is true whether a sample is in any chemical form. It does not harm the initial sample and is therefore possible to detect very sensitive material.40 Raman spectroscopy has a intensified tolerance to water, which allows it to be used for biological studies. Each method has been discussed on the basis of their use in food chemistry, how they work, and the advantages and disadvantages to better understand the most relevant uses in food chemistry.
Chemistry is “the science that deals with the composition and properties of substances and various elementary forms of matter”. There are five branches of chemistry. There is organic chemistry, analytical chemistry, physical chemistry, inorganic chemistry, and biochemistry. We are affected by chemistry everyday. Whether it is the air we breathe or what is in soil, chemistry is everywhere. You can get various careers that involve the use of chemistry. You can be a forensic chemist, a geochemist,
Chemistry and technology are together and separate. Chemistry uses technology and technology uses chemistry. The history of chemistry and technology is long going back to the ancient times. Chemistry was used even by the oldest civilizations, like Egypt. It was really popular during the medieval times. Back then it was called Alchemy, which is turning metal into gold or even about the philosopher’s stone. As the years went by, Alchemy became a lost art and chemistry took it in place. Chemistry led
oldest and core fields of engineering. You might be wondering what exactly chemical engineering is all about. “Chemical engineering is a branch of engineering that applies physical sciences, physics, chemistry, life sciences, microbiology and biochemistry, together with applied mathematics and economics to produce, transform, transport, and properly use chemicals, materials and energy. “Chemical engineers work to improve the quality of people 's lives. Most items used by people every day have needed chemical
Nutrition labels are the labelings that one sees on food packaging. Nutrition labels have important values and information. All of the values and information involved in a nutrition label involve chemistry. The chemistry within these nutrition labels are essential to everyone and affect people’s daily lives so they know what they are consuming in their bodies. There are many big ideas revolving around nutrition labels. Fats, proteins, carbohydrates and the Kjeldahl Method are just four big ideas
My mother developed type 2 diabetes in her late 30’s, and I witnessed her injecting herself with insulin each morning to ensure that her body functions well throughout the day. That’s not something anyone would look forward to on any given day. Consequently, I would like to be part of a change to find a solution for that situation. It has always intrigued me how the same foods that are necessary for the nourishment of our bodies are the same foods that can cause some of the worst and most life-threatening
Marine Chemistry: Think of marine chemistry as a balance. Both sides of the balance need just the right weight to maintain equilibrium. Now imagine the weights on each side of the balance are variables such as nutrients and that the balance itself is the ocean. If there is too much of one nutrient, the balance tips too far one way, therefore causing the chemistry of the ocean to be thrown off. The chemistry of the ocean is what drives its overall function. If there is too much of one thing or
Chemical engineers who have a bachelor 's degree generally start as assistants to experienced engineers. As with any job after they gain experience, to which they are given more responsibility. They can become team leaders or technical service and development (TS&D) officers. The TS&D engineer expands the applications for his or her company 's products and then finds new ones. Some chemical engineers go on to become managers or even executives
The Chemistry of Nutrition is the understanding of the reactions in nutrition. Nutrition is the study of how food and drinks affect our bodies with special regards to the essential nutrients to support our human health. There comes a process of what chemical nutrition does in the area of chemistry. There are many components when the topic of nutrition in chemistry is talked about, you’ll have to talk about what monomers and polymers are, what the entire process of nutrients is, and
Distilled water is popular and has been around for thousands of years. Distilled water is a form of purified water whether by the ways of the past or the technology of the present. This purified water is what we, as humans, mainly drink. "Water is a clear, odorless, tasteless liquid which is essential for most animal and plant life and is an excellent solvent for many substances" (National Center for Biotechnology Information, n.d.). Water is the most common and useful substance in the world. History
Biochemists are scientists who study the chemistry relating to, biological organisms. It forms a bridge between biology and chemistry by studying how complex chemical reactions and chemical structures give rise to life and life's processes. Their work includes studying the complex chemical combinations and reactions involved in metabolism, reproduction, growth, and heredity. Biochemistry is sometimes viewed as a hybrid branch of organic chemistry which specializes in the chemical processes and chemical
What criteria connects biology to chemistry? -Chemistry has changed the way the world is today. -Biology has changed how certain organisms live and stay alive today. I will explain how chemistry and biology connect throughout the world today. Following questions: •What was this society like before the discovery of biology? Biology is the study of living organisms and how organisms may live after awhile. Aristotle discovered biology in 1802.The term biology was first coined by gifted gottfried Reinhold
chemicals. Therefore, the field of forensic chemistry exists – to apply chemistry and forensic toxicology techniques (study of poisons in a legal setting) for analyzing evidence in a crime scene. Forensic chemists use a wide array of laboratory techniques and instruments to analyze the evidence that is brought to them, and determine if it has any implications in a legal setting. To become a forensic chemist, all someone needs is a bachelor’s degree in either chemistry or forensic science from an accredited
Commonly Used and Controversial Food Additives We consume more of them everyday, but many people do not know what additives do to food and the people that eat it. The average person is amazed by the number of additives injected into our food. Through years of scientific research, it is now possible to comprehend the most commonly used and controversial additives. What exactly is a food additive? The technical definition is "any substance the intended use of which results or may reasonably
Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire, the science of Organic chemistry did not develop until the turn of the eighteenth century, mainly in France at
together with light. Photosynthesis is the process of converting sunlight into food for organic organisms such as plants. Photosynthesis is the basis of life for planet earth and without it; not only would we not be able to produce the fruits and vegetables that we consume, but the food to feed the animals that we eat. Plants absorb this sunlight which in turn makes oxygen in a process called respiration. This delicate cycle is what allows us to thrive on this planet. Although much of the life on this planet
