BHTLearning how to maximize your health and energy without having to eat more. Learn about the chemistry of food, and how certain foods that are eaten together can benefit you, and how other foods that are eaten together can actually minimize the benefits from those foods. The timing of when you should eat certain foods is also important. Like if you eat bread before your main meal you could spike your blood sugar and amp up your appetite. But if you eat the bread after your dinner you will slow down the process of carbohydrates turning into sugar. Food combinations also effect flavor and taste. You can eat the same healthy foods everyday, but there are some foods that you shouldn't eat all the time every day. it is important to vary your diet to make sure that you are covering all your nutritional needs, and that you're not getting too much of any one food, because some foods can be harmful to certain people, and you could also develop intolerances. You should also know which vitamins that should be taken together for maximum effect, and know which supplements that should not be taken together

Food Chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods.

Food Physical Chemistry is considered to be a branch of Food chemistry concerned with the study of both physical and chemical interactions in foods in terms of physical and chemical principles applied to food systems, as well as the applications of physical/chemical techniques and instrumentation for the study of foods.

Food Science is the applied science devoted to the study of food. The Institute of Food Technologists defines food science as "the discipline in which the engineering, biological, and physical sciences are used to study the nature of foods, the causes of deterioration, the principles underlying food processing, and the improvement of foods for the consuming public.

Food Engineering is a multidisciplinary field of applied physical sciences which combines science, microbiology, and engineering education for food and related industries. Food engineering includes, but is not limited to, the application of agricultural engineering, mechanical engineering and chemical engineering principles to food materials. Food engineers provide the technological knowledge transfer essential to the cost-effective production and commercialization of food products and services. Physics, chemistry, and mathematics are fundamental to understanding and engineering products and operations in the food industry.

In scientific terms it would be exploring the effects of alcohol on the human mind and body. And not all students will drink because you will need some students to be researchers who are sober and not affected by a chemical substance, so that their judgment, cognition, consciousness, memory, concentration, function, performance, ability, capacity, vision, hearing and mobility is not impaired in any way.
Flavor and balance are probably the most important components of cocktail quality, but it's the temperature, texture, aroma, strength, and presentation that makes for a wel-rounded drink. Some Texture Descriptors for Cocktails and Spirits are: Thick, syrupy, not dilute enough. Thin, weak, non-integrated, over-shaken. Silky. Light. Bubbly, fizzy. Tannic, astringent. Soft, pillowy, foamy, frothy. Slushy, viscous, chewy. Crunchy. (crisp, firm, dry, and brittle). Gloppy, chunky (pieces of a substance mixed in with something creamier). Viscosity - Pudding (wiki) - Watery or Creamy? Cold or Warm?

Creamy is food or drink having the rich taste or a thick smooth texture.

Molecular Gastronomy is a subdiscipline of food science that seeks to investigate the physical and chemical transformations of ingredients that occur in cooking. Its program includes three axes, as cooking was recognized to have three components, which are social, artistic and technical. Molecular cuisine is a modern style of cooking, and takes advantage of many technical innovations from the scientific disciplines.

Organic Synthesis is a special branch of chemical synthesis and is concerned with the construction of organic compounds via organic reactions. Organic molecules often contain a higher level of complexity than purely inorganic compounds, so that the synthesis of organic compounds has developed into one of the most important branches of organic chemistry.

Nutrition Knowledge

Antinutrient are natural or synthetic compounds that interfere with the absorption of nutrients. Nutrition studies focus on
those antinutrients commonly found in food sources and beverages. Protease inhibitors are substances that inhibit the actions of trypsin, pepsin and other proteases in the gut, preventing the digestion and subsequent absorption of protein. For example, Bowman-Birk trypsin inhibitor is found in soybeans.

Coffee


Taking vitamins at the same time as a cup of coffee or tea can interfere with the body's absorption of many necessary nutrients. It is probably better to consume your caffeine between meals, not just before or just after. Caffeine is also a mild diuretic, which increases urination. So water soluble vitamins, such as the B-vitamins, can be depleted as a result of the fluid loss. Water-soluble vitamins: Vitamin C, biotin and the seven B vitamins — thiamin (B-1), riboflavin (B-2), niacin (B-3), pantothenic acid (B-5), pyridoxine (B-6), folic acid (B-9) and cobalamin (B-12).

Coffee also increases the excretion of the minerals magnesium, potassium, sodium and phosphate. There is also evidence that caffeine interferes with the action of vitamin A. Dehydration

Unfiltered coffee is a significant source of cafestol and kahweol, diterpenes that have been found to raise serum total and LDL cholesterol concentrations in humans.

Caffeine causes calcium to be excreted in the urine and feces. For every 150 mg of caffeine ingested, about the amount in one cup of coffee, 5 mg of calcium is lost. Caffeine inhibits vitamin D receptors, which limit the amount that will be absorbed. Because vitamin D is important in the absorption and use of calcium in building bone, this could also decrease bone mineral density, resulting in an increased risk for osteoporosis. Caffeine interferes with the body's absorption of iron, which is necessary for red blood cell production.  Caffeine may reduce the absorption of manganese, zinc and copper. So don't take vitamins with coffee.

The Plant:
There are around 70 types of the Coffea flowering plant, and two major types, Coffea Arabica (Arabica beans) and Coffea canephora var. Robusta (Robusta beans).  Coffee Production - The Coffee Faq - The History of Coffee

Coffee is a brewed drink prepared from roasted coffee beans, which are the seeds of berries from the Coffea plant, which is a genus of flowering plants whose seeds, called coffee beans, are used to make various coffee beverages and products. It is a member of the family Rubiaceae. They are shrubs or small trees native to tropical and southern Africa and tropical Asia. Coffee contains many phytochemicals, antioxidants and other nutrients that research has shown as beneficial to our bodies.

Roasting:

Beans are baked somewhere between 180 and 250 degrees Celsius for somewhere between 2 and 25 minutes. During the scorch, sugars and fats degrade, amino acids and sugars react with each other, and degradation products spark chain reactions.
culminates in the formation of dozens of aromatic compounds that make up that enticing coffee bouquet.
Coffee Roasting - Maillard Reaction

Compounds:

Compounds include aldehydes, ketones, furans, pyrazines, pyridines, phenolic compounds, indoles, lactones, esters and benzothiazines. But for chlorogenic acids, more roasting leads to less of these beneficial phenols. Chlorogenic acids: Around 45 of these phenolic compounds have been found in coffee caffeic acid, anti-inflammatory and antibacterial properties.
Trigonelline: This bitter alkaloid has been linked to protecting the brain from damage, blocking cancer cells from moving around, combating bacteria, and lowering blood sugar and total cholesterol. Kahweol and cafestol: These diterpenes, which contribute to the bitter taste of coffee, have been linked to preventing and battling cancer cells. But, they’ve also been linked to raising cholesterol.

Grinding:

Using a standard home grinder for 42 seconds compared with 5 seconds doubled the amount of caffeine squeezed out of a 37 gram portion.  Rok Hand Coffee Grinder   RAFINO Coffee Grind Refining System.

Brewing:

Brewing methods are also critical for squeezing out the goodness of the beans. There’s a variety of methods to choose from: Brief boiling (Turkish), steeping (French press), Filtering (drip coffee), and pressurized (espresso). Espresso machines, which force hot (91-96 degrees Celsius) pressurized (~9 bar) water evenly over fine, well-packed coffee grinds, produces the brews with the most concentrated doses of caffeine.

In the early morning, our bodies produce high levels of cortisol, the stress hormone that helps us become more alert. Filling the body with caffeine first thing in the morning signals the body to make less cortisol, which means the body will start relying on coffee, rather than its natural functions, to wake up. So waiting a couple of hours after you wake up to drink your coffee will benefit you more.

Coffee grounds improve compost
Coffee grounds improve compost in two ways. They typically contain about 2% nitrogen (the same amount as manure), which feeds the micro-organisms that digest plant debris and turns it into compost. Second, as they decompose, coffee grounds have been shown to suppress common fungal rots and reduce the growth of E. coli and Staphylococcus spp, according to research published by Washington State University. For optimal compost disease-suppression, shoot for 10 to 20 percent coffee grounds per total compost volume. Earthworms also love coffee grounds. Leaving a bowlful of used grounds in the fridge overnight will rid your icebox of icky odors.

Pairing Foods for Flavor Enhancement


Flavor is the sensory impression of food or other substance, and is determined primarily by the chemical senses of taste and smell. The "trigeminal senses", which detect chemical irritants in the mouth and throat as well as temperature and texture, are also important to the overall Gestalt of flavor perception. The flavor of the food, as such, can be altered with natural or artificial flavorants which affect these senses.
Flavor Pairing

Food Pairing is a method for identifying which foods go well together. The method is based on the principle that foods combine well with one another when they share key flavor components. Foodpairing is a relatively new method and is often confused with wine and food matching. By contrast, foodpairing uses HPLC, gas chromatography and other laboratory methods to analyse food and to find chemical components that they have in common.

Sense of Taste


Sweet - Salty - Sour - Bitter

Taste is one of the five traditional senses that belongs to the gustatory system. Taste is the sensation produced when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with smell (olfaction) and trigeminal nerve stimulation (registering texture, pain, and temperature), determines flavors of food or other substances. Humans have taste receptors on taste buds (gustatory calyculi) and other areas including the upper surface of the tongue and the epiglottis. Every Flavor is a Chemical Compound.

Umami, which is the fifth taste, which is the mysterious but interesting pleasant savory taste.

Palate is the roof of the mouth in humans and other mammals. It separates the oral cavity from the nasal cavity. The palate is divided into two parts, the anterior bony hard palate, and the posterior fleshy soft palate (or velum).

Palate Cleanser is generally a neutral flavored element in food that enables to clear the palate from one flavor to another; in cultures where diversity of flavors in dishes is customary, the palate cleanser is considered an essential companion to entrees.

Palatability is the hedonic reward (i.e., pleasure) provided by foods or fluids that are agreeable to the "palate", which often varies relative to the homeostatic satisfaction of nutritional, water, or energy needs. The palatability of a food or fluid, unlike its flavor or taste, varies with the state of an individual: it is lower after consumption and higher when deprived. Palatability of foods, however, can be learned. It has increasingly been appreciated that this can create a hedonic hunger that is independent of homeostatic needs.

Tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication, and is used in the act of swallowing. It is of importance in the digestive system and is the primary organ of taste in the gustatory system. The tongue's upper surface (dorsum) is covered in taste buds housed in numerous lingual papillae. It is sensitive and kept moist by saliva, and is richly supplied with nerves and blood vessels. The tongue also serves as a natural means of cleaning the teeth. A major function of the tongue is the enabling of speech in humans and vocalization in other animals.

Taste Buds contain the taste receptor cells, which are also known as gustatory cells. The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, the cheek and epiglottis. These structures are involved in detecting the five elements of taste perception: salty, sour, bitter, sweet and umami; through the combination of these elements we detect "flavors." A popular myth assigns these different tastes to different regions of the tongue; in reality these tastes can be detected by any area of the tongue. Via small openings in the tongue epithelium, called taste pores, parts of the food dissolved in saliva come into contact with the taste receptors. These are located on top of the taste receptor cells that constitute the taste buds. The taste receptor cells send information detected by clusters of various receptors and ion channels to the gustatory areas of the brain via the seventh, ninth and tenth cranial nerves. On average, the human tongue has 2,000–8,000 taste buds.

Taste Receptor is a type of receptor which facilitates the sensation of taste. When food or other substances enter the mouth, molecules interact with saliva and are bound to taste receptors in the oral cavity and other locations. Molecules which give a sensation of taste are considered "sapid". Taste receptors are divided into two families: Type 1, sweet, first characterized in 2001: TAS1R2 – TAS1R3. Type 2, bitter, first characterized in 2000:[3] TAS2R1 – TAS2R50, and TAS2R60. Combinations of these receptors in dimers or other complexes contributes to different perceptions of taste. Visual, olfactive, “sapictive” (the perception of tastes), trigeminal (hot, cool), mechanical, all contribute to the perception of taste. Of these, transient receptor potential cation channel subfamily V member 1 (TRPV1) vanilloid receptors are responsible for the perception of heat from some molecules such as capsaicin, and a CMR1 receptor is responsible for the perception of cold from molecules such as menthol, eucalyptol, and icilin.

TAS2R38 is a protein that in humans is encoded by the TAS2R38 gene. TAS2R38 is a bitter taste receptor.

Aryl Hydrocarbon Receptor is a protein that in humans is encoded by the AHR gene. The aryl hydrocarbon receptor is a ligand-activated transcription factor involved in the regulation of biological responses to planar aromatic (aryl) hydrocarbons. This receptor has been shown to regulate xenobiotic-metabolizing enzymes such as cytochrome P450. Phenotype

Dysgeusia is a distortion of the sense of taste. Dysgeusia is also often associated with ageusia, which is the complete lack of taste, and hypogeusia, which is a decrease in taste sensitivity.

Taste receptors really are everywhere, including the colon. And if it gets exposed to too much bitterness, it triggers a release of ions, which in turn causes water to pour into the gut via osmosis, and the body experiences diarrhea.

Our Perceptions of food can also effect flavor. People have been known to like a wine more when they were told it's expensive.
You can also gross yourself out.  And people who get sick from a particular food will also perceive that food differently.
People can also perceive certain foods differently when having Hypersensitivity or Hyposensitivity, which is less than normal sensitivity to a foreign agent, such as an allergen, in which the response is unusually delayed or lessened in degree. Also called hypoergia. Your flavor perception can also change when there is too many foods blended together, Crossmodal.

I don't let taste tell me what to eat. Though it's important that we understand that taste my be an indication that some food may not be safe for us to eat, we can not let taste stop us from eating food that we know is good for us.

Olfactory white is a smell composed of many equally strong but diverse smells, perhaps over 30. Mixtures of many different smells across the perceptual range all tend to smell very similar to humans, despite different components making them up. The concept is similar to all different spectral colours combining to form white. Olfactory white is neither pleasant or unpleasant.



Scents and Smells


The Power of Smell


"The human nose can distinguish at least 1 trillion different odours?"

Olfaction is the sense of smell. This sense is mediated by specialized sensory cells of the nasal cavity of vertebrates, which can be considered analogous to sensory cells of the antennae of invertebrates. In humans, olfaction occurs when odorant molecules bind to specific sites on the olfactory receptors. These receptors are used to detect the presence of smell. They come together at the glomerulus, a structure which transmits signals to the olfactory bulb (a brain structure directly above the nasal cavity and below the frontal lobe).

Olfactory System is the part of the sensory system used for smelling (olfaction). Most mammals and reptiles have a main olfactory system and an accessory olfactory system. The main olfactory system detects airborne substances, while the accessory system senses fluid-phase stimuli. The senses of smell and taste (gustatory system) are often referred to together as the chemosensory system, because they both give the brain information about the chemical composition of objects through a process called transduction.

Olfactory Receptors act as Sensitive Chemical Sensors and are found in other areas of the body, and not just our nose.
More of our DNA is devoted to genes for different olfactory receptors than for any other type of protein.
Artificial Intelligent Sensors

Anosmia is the inability to perceive odor or a lack of functioning olfaction—the loss of the sense of smell. Anosmia may be temporary, but some anosmia (including traumatic anosmia) can be permanent. Anosmia is due to a number of factors, including an inflammation of the nasal mucosa, blockage of nasal passages or a destruction of one temporal lobe. Inflammation is due to chronic mucosa changes in the paranasal sinus lining and the middle and superior turbinates.

Olfactory Fatigue is the temporary, normal inability to distinguish a particular odor after a prolonged exposure to that airborne compound. For example, when entering a restaurant initially the odor of food is often perceived as being very strong, but after time the awareness of the odor normally fades to the point where the smell is not perceptible or is much weaker. After leaving the area of high odor, the sensitivity is restored with time. This is one of the reasons why we can't tell how bad we smell because we adapt to smells very quickly.

Parosmia is an olfactory dysfunction that is characterized by the inability of the brain to properly identify an odor's "natural" smell. What happens instead, is that the natural odor is transcribed into what is most often described as an unpleasant aroma, typically a "'burned,' 'rotting,' 'fecal,' or 'chemical' smell." There are instances, however, of pleasant odors. This is more specifically called euosmia (Gk.).

Smell Disorders

Odor is caused by one or more volatilized chemical compounds, generally at a very low concentration, that humans or other animals perceive by the sense of olfaction. Odors are also commonly called scents, which can refer to both pleasant and unpleasant odors.

Aroma is a chemical compound that has a smell or odor. A chemical-compound has a smell or odor when it is sufficiently volatile to be transported to the olfactory system in the upper-part of the nose.
