Salt is one of the most ubiquitous food ingredients around. Those who think of salt only as something used to perk up flavor might wonder what could possibly give this ingredient the level of importance it has gained through the ages. In reality, there is much more to this crystalline cube than first meets the eye.



Besides enhancing taste, salt has several other functions in food products. It acts as an antimicrobial or microbiological control agent. It contributes to certain chemical reactions that create a wide variety of food characteristics.



Sometimes the terms "salt" and "sodium" are used interchangeably, but technically this is not correct. "Salt" is sodium chloride. By weight, it is 40 percent sodium and 60 percent chloride.

Most foods and tap water contain sodium and chloride. Sodium is an essential nutrient, a mineral that the body cannot manufacture itself.

Because of sodium's importance to your body, the excretory and nervous systems guard against under-consumption of salt, which is a threat to your body's nerves and muscles. Other ions such as calcium, magnesium, and potassium are also very important. Concentrations of these ions are held in narrow ranges by the kidney.



The association between eating salt and the risk of blood pressure increasing is difficult to quantify. Some people are sensitive to changes in salt intake whereas others can adjust so that blood pressure does not rise at all.



Americans typically consume 4,000-8,000 mg each day, well above their daily needs. A goal for moderation for all adults, (including pregnancy and lactation) is approximately 2,400 mg of sodium per day.

Flavor(s) Natural Smoke

Smoke flavor is made by condensing the smoke used from cooking with a wood fire into water. The components of the water are filtered and the flavorful components are retained. There are certain criteria for approving labels labeled with “smoke flavor.” If it is directly added to the product, “smoke flavor” is labeled right after the product or ingredient (e.g. Chicken soup smoke flavor). The phrase “added” must be after the “smoke flavor” if the flavoring is added through another product indirectly. If liquid smoke was sprayed onto the product, the labeling would simply read “smoke flavoring added.” Smoked flavoring currently issues a concern with the burning of beech wood which produces AM01 when condensed with water. The study was not conclusive, but the evidence of the toxic nature of AM01 is enough to make natural smoked flavoring controversial.

"The term natural flavor or natural flavoring means the essential oil, oleoresin, essence or extractive, protein hydrolysate, distillate, or any product of roasting, heating or enzymolysis, which contains the flavoring constituents derived from a spice, fruit or fruit juice, vegetable or vegetable juice, edible yeast, herb, bark, bud, root, leaf or similar plant material, meat, seafood, poultry, eggs, dairy products, or fermentation products thereof, whose significant function in food is flavoring rather than nutritional."

The new labeling law effective in 2006, The Food Allergen Labeling and Consumer Protection Act (FALCPA), requires manufacturers to declare if one or more of the 8 major food allergens are contained in a natural flavoring. The top 8 major food allergens are defined as: milk, egg, fish, crustacean shellfish, tree nuts, wheat, peanuts and soybeans.

If you are managing food allergies other than the top 8 major food allergens, however, the new law will not be of assistance to you in identifying the sources in any natural flavoring stated on a label.

The FDA does not require companies to disclose ingredients of color or flavor additives so long as all the chemicals in them are considered by the agency to be GRAS ("generally recognized as safe") enabling companies to maintain secrecy of formulas. It also hides the fact that flavors often contain more ingredients than the foods to which they give taste.

A typical artificial strawberry flavor contains over 30 chemicals. According to manufacturer safety data sheets those chemicals cause eye irritation, corneal damage, eye burns, skin irritation, severe / permanent damage to digestive tract, gastrointestinal irritation, gastrointestinal tract burns, CNS depression, neurological effects, liver abnormalities, cardiac abnormalities, or other harm.

Natural flavor, according to the FDA, must be derived entirely from natural sources (herbs, spices, fruits, vegetables, beef, chicken, yeast, bark, roots, etc). Consumers prefer to see natural flavors on a label out of a belief they are more healthful.

Natural flavor is not necessarily more healthful or purer than an artificial flavor. Almond flavor when derived from natural sources may contain traces of hydrogen cyanide, a deadly poison. When derived by mixing oil of clove & amyl acetate, it does not. Natural flavors and artificial flavors are often manufactured at same chemical plants.

Flavor manufacturing may also involve biotechnology, using enzyme reactions, fermentation, & fungal and tissue cultures. Flavors created by these methods are considered natural flavors by the FDA.

In addition to flavor chemicals also think about genetic engineering of food, DNA or gene alteration, and medicines and hormones given to cows, cattle, hogs, and chickens. What affect does it have upon us? Some are suspected causes of cancer or other problems.

When a natural flavor or artificial flavor is added to a food or drink the resultant processed food is no longer natural & is potentially harmful.

it is a chemical food additive whose chemical structure resembles Vitamin C or Ascorbic Acid. It is used in the food processing industry to preserve the color of cured meats and related products. It actually is a chemical salt of Erythorbic Acid.

A chemical compound that is used to preserve food by retaining the moisture in the food to make it juicy and more pleasing when consumed.

According to Larry Borchert, a professor of

muscle biology and meat science at the

University of Wisconsin at Madison, hams do

not naturally hold water. The two proteins that make up the muscles of a ham, actin and

myosin, bind together to form a complex

protein known as actomyosin. Actomyosin is

not water-soluble, but it is salt- soluble. Thus ham manufacturers

must inject sodium phosphate into

supermarket hams to

enable the muscles to retain water. The

advantage of this treatment can be that a ham does not end up completely

dehydrated after processing. The disadvantage, however, is that the ham can be so pumped up with water, or "highly extended," as Borchert phrased it, that it

takes on an unpalatably damp, spongy texture

and a watered-down flavor. This was the case with all of the "water product" hams and, to a lesser degree, the "hamwater

added"

We get our energy from the nutrients in food. The main sources of energy are carbohydrates (starches and sugars), fats and proteins. The body can be compared to an engine that converts the energy in food into the energy we need to live. Sugars and starches are forms of carbohydrate. Nutritionists recommend that about half of our energy should be supplied by carbohydrates. The majority of this should be from starchy foods like cereals, rice, potatoes, pasta or bread, with the remainder coming from sugars. During digestion (the process by which we break down food substances ready for absorption and use by the body) complex starchy foods are broken down into sugars.

Sodium Nitrate (Nitrite)

Sodium Nitrate and Sodium Nitrite are both salts used as preservatives in processed meats. Sodium Nitrate, NaNO3, is used as a food preservative because of its anti-microbial properties so food stays fresher longer. It is also used broadly as a fertilizer and in the late 19th century was used in the manufacturing of gunpowder. There is controversy of its use because it can produce nitrosamines, which cause cancer, when food with sodium nitrate is cooked at high heat. Sodium Nitrite, NaNO2 , is chemically similar to Sodium Nitrate, and is used to sustain coloring and preserve freshness in meats and fish. Without the coloring, hot dogs would get a grayer color over time. Sodium Nitrite is also found in dyeing, printing, and bleaching textile fabrics, coating metals, and manufacturing rubber chemicals. Over-consumption of sodium nitrate can increase the risk of pancreatic cancer. Nitrates are naturally occuring in cauliflower, spinach, and other vegetables as well.

Flavoring

This term is usually followed by a specific food item. The flavor shows the consumer that the product has the taste of that specific food item, but not necessarily containing all the ingredients to produce that flavor. For example, butter flavor is not really butter added into the food. Dried food can be used as flavoring such as cheddar cheese. Movie popcorn has butter flavoring added to it, which is flavored vegetable oil and much cheaper than actual butter. Ingredients of butter flavoring include everything but butter such as partially hydrogenated soybean oil, Beta Carotene, TBHQ, Dimethylpolysiloxane, etc. The resulting flavor is produced, but the health risks are increased. See Artificial Flavor. The label “flavor” is to imitate a certain food item’s taste without putting all the necessary ingredients without changing the texture.

The cut of meat from a hog's hind leg, generally from the middle of the shank bone to the aitch (hip) bone. The actual length of the cut varies according to the producer. The unprocessed meat is referred to as fresh ham, but most ham goes through a curing process after which it's referred to as cured ham.



Smoking is the process of flavoring, cooking, or preserving food by exposing it to the smoke from burning or smoldering plant materials, most often wood. Meats and fish are the most common smoked foods, though cheeses, vegetables, and ingredients used to make beverages such as whisky,[1] Rauchbier, and lapsang souchong tea are also smoked.





Pork ribs being smokedIn Europe, alder is the traditional smoking wood, but oak is more often used now, and beech to a lesser extent. In North America, hickory, mesquite, oak, pecan, alder, maple, and fruit-tree woods such as apple, cherry and plum are commonly used for smoking. Other fuels besides wood can also be employed, sometimes with the addition of flavoring ingredients. Chinese tea-smoking uses a mixture of uncooked rice, sugar, and tea, heated at the base of a wok. Some North American ham and bacon makers smoke their products over burning corncobs. Peat is burned to dry and smoke the barley malt used to make whisky and some beers. In New Zealand, sawdust from the native manuka (tea tree) is commonly used for hot smoking fish.



Historically, farms in the western world included a small building termed the smokehouse where meats could be smoked and stored. This was generally well-separated from other buildings both because of the fire danger and because of the smoke emanations.

BHA

Butylated hydroxyanisole (BHA) is used as an antioxidant to prevent fats and oils from becoming rancid. BHA and BHT can be found in butter, meats, chewing gum, dehydrated potatoes, and beer. To be Generally Recognized As Safe (GRAS) by the Food and Drug Administration (FDA), the food product must have at maximum .02% of BHA to be considered safe. BHA is a known carcinogen in rats, mice, and hamsters. However, the cancer developed from cells in the forestomach in the rodents that humans do not have. BHA did not cause tumors to develop in dogs, pigs, and monkeys tested who do not have forestomachs. Although the true effects of BHA on the human body is not known, BHA is not a stable compound and people are at risk for triggering a reaction upon consumption.

The majority of consumers prefer beef with a white, or creamy white, fat rather than a yellowish fat. Previous studies reported in the literature have shown that cattle finished on grain-based diets have generally produced carcasses with a whiter fat than those finished at pasture, an effect thought to reflect the lower content of carotenoids in grain.

Maltodextrin is a flavorless, easily digested carbohydrate made from cornstarch. A natural, complex carbohydrate, it is not a simple sugar (dextrose, fructose, sucrose etc.) It can be derived from potato or corn starch; used in food industry such as sweets, drink, beer, ice cream, preserved fruit, milk powder, malted mild, cake, biscuit and bread, as well as in medicine, textile, printing and dyeing, paper making, casting and petroleum drilling; generally recognized as safe.



Maltodextrin often contains Monosodium Glutimate (MSG), to which many people have an adverse reaction to.

Nutritionists recommend that about half of our energy should be supplied by carbohydrates.

During digestion (the process by which we break down food substances ready for absorption and use by the body) complex starchy foods are broken down into sugars.

One of the most widely used colors is caramel, the color of burnt sugar.



There are many different types of caramel color, each engineered to serve a particular purpose in food chemistry. They are all based on the cooking of sugars and starches. Sometimes acids such as acetic acid, citric acid, lactic acid, or phosphoric acid, are used to break the bonds between sugars to create invert sugars, or to make sugars from starches, before the sugars are raised to a higher temperature for carmelization.



The heat is carefully controlled during carmelization to get the right products from the reaction. Besides acids, alkalies and salts may be used to further control the process.



Caramel color is a colloid, a mixture in which solid particles are suspended in water. The particles in colloids have electric charges that keep the particles from clumping together and settling out of solution. The charges can be positive or negative. If a negative coloid is added to a product that has positive colloidal particles in it, the two will attract one another and clump up, making the product cloudy.



Caramel color can be made with either positively or negatively charged particles. This allows manufacturers to use negative colloidal caramel in acidic soft drinks, and positive in beers and soy sauces. Beer has positively charged proteins suspended in it, and soy sauce has a high salt content that requires the more salt-tolerant positive caramel color.



Caramel color is an emulsifying agent as well as a colorant. In soft drinks, it helps keep the flavor oils suspended in the solution.



In chocolate milk, the muddy color of caramel is darkened by the addition of FD&C Red #40 to give what the industry refers to as a "Dutch" chocolate shade. Blues and yellows are sometimes used to give a more brown color.



Caramel color is added to baked goods, to poultry, to milk to give an "eggnog" color, to malt vinegars, canned meats, syrups, and soups, stews, and gravies.



If caramel color is made in North America it is likely to be gluten-free.



The problem with caramel color is that it may or may not contain gluten depending on how it is manufactured. In the USA caramel color must conform with the FDA standard of identity from 21CFR CH.1. This statute says: "the color additive caramel is the dark-brown liquid or solid material resulting from the carefully controlled heat treatment of the following food-grade carbohydrates: Dextrose (corn sugar), invert sugar, lactose (milk sugar), malt syrup (usually from barley malt), molasses (from cane), starch hydrolysates and fractions thereof (can include wheat), sucrose (cane or beet)." Also, acids, alkalis and salts are listed as additives which may be employed to assist the caramelization process.

Soy Protein Hydrolyzed

Hydrolyzed soy protein is a highly processed soy byproduct that is used as a flavor enhancer. The hydrolysis method is done by boiling the soy in acid and neutralizing it with caustic soda. The residue after the process is finished is soy protein and excitotoxic amino acids such as glutamate. See Monosodium Glutamate (MSG). Because of the amount of glutamate in the hydrolyzed soy protein, manufacturers use it exactly as MSG but are not required to put “MSG” under their labeling. Hydrolyzed soy protein is also used in cosmetics and personal care products such as hair conditioner, hair dyes, lotion, skin care products, and mascara. In addition, it can also be a component in paper and paper board. People with soy allergies must be careful with the labeling because it is the proteins in the soy that they are intolerant of. Their bodies do not recognize the soy protein as safe and will result in the production of histamine. Histamine is the main hormone released as an inflammatory response. The allergic reaction will trigger inflammation of soft tissue such as lungs and sinuses. The Food and Drug Administration (FDA) has considered soy protein as an indirect food additive and is Generally Recognized As Safe (GRAS).

Disodium Guanylate

Disodium Guanylate, or E628, is a flavor enhancer similar to Monosodium Glutamate (MSG) and Disodium Inosinate but more effective. It is about 50 to 100 times more potent than MSG. Disodium 5’-guanylate is made from yeast ribonucleic acid, similar to genetic material. The savory taste of food becomes more developed without the disodium guanylate providing its own flavor. . It is produced by microbial fermentation in vegetables and put in tapioca starch to make it a powder form. It is approved by the Food and Drug Administration but like MSG, is associated with certain allergic reactions after consumption. See Monosodium Glutamate.

Disodium 5’-inosinate, or E631, comes from the nucleotide Inosine monophosphate (IMP) commonly found in mushrooms and meats. Nucleotides are information-carrying molecules (seen in DNA) and help with the body’s metabolic processes. It is produced by microbial fermentation in vegetables and put in tapioca starch to make it a powder form. It is approved by the Food and Drug Administration but like MSG, is associated with certain allergic reactions after consumption. See Monosodium Glutamate.

Monosodium Glutamate

Monosodium Glutamate (MSG) is used in foods as a flavor enhancer while not providing their own separate flavor. The white crystalline powder is derived from glutamic acid, one of the 22 essential amino acids. Glutamic acid is present in seaweed, vegetables, cereal gluten, but MSG is not found naturally by itself. The Federal Drug Administration recognizes MSG to be Generally Recognized As Safe (GRAS). Consuming MSG Is not a health hazard to the individual, but some may exhibit allergic reactions due to hypersensitivity. Symptoms are temporary but may include a burning sensation, facial pressure, headache, nausea or chest pains.

Torula, in its inactive form (usually labeled as torula yeast), is widely used as a flavouring in processed foods and pet foods. It is produced from wood sugars, as a by-product of paper production. It is pasteurized and spray-dried to produce a fine, light grayish-brown powder with a slightly yeasty odor and gentle, slightly meaty taste.
