What Are Food AdditivesVIDEO ON THE TOPIC: Awesome Automated Bakery Production Line on Food Factory - Delicious Donuts and Cake Making Machines
I was there undercover, to attend an annual trade show called Food Ingredients. It is not open to the public. Anyone who tries to register has to show that they work in food manufacturing; I used a fake ID. While exhibitors at most food exhibitions are often keen for you to taste their products, few standholders here had anything instantly edible to offer. A pastry chef in gleaming whites rounded off his live demonstration by offering sample petits fours to the buyers who had gathered.
His dainty heart- and diamond-shaped cakes were dead ringers for those neat layers of sponge, glossy fruit jelly, cream and chocolate you see in the windows of upmarket patisseries, but were made entirely without eggs, butter or cream, thanks to the substitution of potato protein isolate. This is the goal of the wares on show, something the marketing messages make clear. Gleaming glass shelves were back-lit to show off a rainbow of super-sized phials of liquids so bright with colouring, they might be neon.
The broad business portfolio of the companies exhibiting at Food Ingredients was disconcerting. At Frankfurt, Omya was selling granular onion powder, monosodium glutamate and phosphoric acid. For big companies such as this, food processing is just another revenue stream. They experience no cognitive dissonance in providing components not only for your meal, but also for your fly spray, scratch-resistant car coating, paint or glue.
The conference was the domain of people whose natural environment is the laboratory and the factory, not the kitchen, the farm or the field; people who share the assumption that everything nature can do, man can do so much better, and more profitably. Tired after hours of walking round the fair, and, uncharacteristically, not feeling hungry, I sought refuge at a stand displaying cut-up fruits and vegetables; it felt good to see something natural, something instantly recognisable as food.
But why did the fruit have dates, several weeks past, beside them? A salesman for Agricoat told me that they had been dipped in one of its solutions, NatureSeal, which, because it contains citric acid along with other unnamed ingredients, adds 21 days to their shelf life. For the salesman, this preparation was a technical triumph, a boon to caterers who would otherwise waste unsold food. Maybe I had bought a tub on a station platform or at a hotel buffet breakfast?
Over recent years, they have been introduced slowly and artfully into foods that many of us eat every day — in canteens, cafeterias, pubs, hotels, restaurants and takeaways.
You might check labels for E numbers and strange-sounding ingredients, boycotting the most obvious forms of processed food. And yet you will still find it hard to avoid the 6, food additives — flavourings, glazing agents, improvers, bleaching agents and more — that are routinely employed behind the scenes of contemporary food manufacture.
When you try to dig deeper, you hit a wall of secrecy. Instead, they leave it to retailers to field any searching questions from journalists or consumers. In turn, retailers drown you in superfluous, mainly irrelevant material. I spent years knocking on closed doors, and became frustrated by how little I knew about contemporary food production. What happens on the farm and out in the fields is passably well-policed and transparent. Abattoirs undergo regular inspections, including from the occasional undercover reporter from a vigilante animal welfare group, armed with a video camera.
My growing preoccupation was instead just how little we really know about the food that sits on our supermarket shelves, in boxes, cartons and bottles — food that has had something done to it to make it more convenient and ready to eat.
Eventually, contacts within the industry provided me with a cover that allowed me to gain unprecedented access to manufacturing facilities, as well as to subscriber-only areas of company sites, private spaces where the chemical industry tells manufacturers how our food can be engineered.
Even with 25 years of food chain investigations under my belt, it was an eye-opener. Anything that comes in a box, tin, bag, carton or bottle has to bear a label listing its contents, and many of us have become experts at reading these labels.
But many of the additives and ingredients that once jumped out as fake and unfathomable have quietly disappeared. Does this mean that their contents have improved? In some cases, yes, but there is an alternative explanation. Some companies have reformulated their products in a genuine, wholehearted way, replacing ingredients with substitutes that are less problematic.
Others, unconvinced that they can pass the cost on to retailers and consumers, have turned to a novel range of cheaper substances that allow them to present a scrubbed and rosy face to the public. Imagine you are standing in the supermarket. Maybe you usually buy some cured meat for an antipasti. Food manufacturers use them to slow down the rate at which foods go rancid, so extending their shelf life.
And the extract does have something to do with the herb, usually in its dried form. Extraction is done by using either carbon dioxide or chemical solvents — hexane derived from the fractional distillation of petroleum , ethanol and acetone. Neutral-tasting rosemary extract is then sold to manufacturers, usually in the form of a brownish powder. Its connection with the freshly cut, green and pungent herb we know and love is fairly remote. Not sure what to have for dinner?
How about a chicken noodle dish? If you noticed that it contained an amino acid such as L-cysteine E, your enthusiasm might wane, especially if you happen to know that this additive can be derived from animal and human hair. But a range of new-wave yeast extracts is increasingly replacing E Ingredients are available in chicken and beef flavour, with roasted or boiled varieties, as well as white meat and dark roast.
Less well known is the fact that yeast extract has a high concentration of the amino acid glutamate, from which monosodium glutamate — better known as MSG, one of the most shunned additives — is derived. What else is in your basket? You read the ingredients: whole milk, sugar well, there had to be some , cream, cocoa powder and dark chocolate.
It all sounds quite upmarket, but then your urge to buy falters as you notice three feel-bad ingredients. The first is carrageenan E , a setting agent derived from seaweed that has been linked with ulcers and gastrointestinal cancer. The second of these worrying ingredients is a modified starch E , or to give it its full chemical name, acetylated distarch adipate. It started off as a simple starch, but has been chemically altered to increase its water-holding capacity and tolerance for the extreme temperatures and physical pressures of industrial-scale processing.
The third problematic ingredient is gelatine. This is anathema to observant Muslims, Jews and vegetarians, and even secular omnivores may be wondering what this by-product of pig skin is doing in their pudding. Fortunately for the manufacturers of your chocolate cream dessert, there is a Plan B.
Again, no E numbers. The history of food processing is littered with ingredients that were initially presented as safer and more desirable, yet subsequently outed as the opposite. Hydrogenated vegetable oils, or margarine, were actively promoted as healthier than the natural saturated fats in butter.
High fructose corn syrup, once marketed as preferable to sugar, has now been identified as a key driver of the obesity epidemic in the US. Is the clean-label campaign a heart-and-soul effort by manufacturers to respond to our desire for more wholesome food? Or just a self-interested substitution exercise? Clean labelling looks less like a thorough spring clean of factory food than a superficial tidy-up, with the most embarrassing mess stuffed in the cupboard behind a firmly shut door — where, hopefully, no one will notice.
From water-injected poultry and powdered coagulated egg, to ultra-adhesive batters and pre-mixed marinades, the raw materials in industrial food manufacturing are rarely straightforward. They may be liquid, concentrated, dried, crystallised, frozen, quick frozen or coagulated.
Manufacturers can also buy in handy pre-cooked, ready-shelled eggs for manufacturing products such as Scotch eggs and egg mayonnaise, or eggs pre-formed into g cylinders or tubes, so that each egg slice is identical and there are no rounded ends.
These hard-boiled, tubular eggs are snapped up by sandwich-making companies. Manufacturers can also take their pick from bespoke egg mixes, which are ready to use in everything from quiches and croissants to glossy golden pastry glazes and voluminous meringues.
No hurry to use them up: they have a shelf life of 18 months. This mature cheese flavouring is then heat-treated to halt enzymatic activity. Hey, presto: mature-tasting cheese in days rather than months.
Traditional cheddar is not considered truly mature until it has spent between nine and 24 months in the maturing room. A factory pantry looks nothing like yours. When the home cook decides to make a Bakewell tart, she or he puts together a lineup of familiar ingredients: raspberry jam, flour, butter, whole eggs, almonds, butter and sugar.
The factory food technologist, on the other hand, approaches the tart from a totally different angle: what alternative ingredients can we use to create a Bakewell tart-style product, while replacing or reducing expensive ingredients — those costly nuts, butter and berries?
How can we cut the amount of butter, yet boost that buttery flavour, while disguising the addition of cheaper fats? How many times can we reuse the pastry left over from each production run in subsequent ones? Which enzyme would keep the almond sponge layer moist for longer? What about coating the almond sponge layer with an invisible edible film that would keep the almonds crunchy for weeks?
Could we substitute some starch for a proportion of the flour to give a more voluminously risen result? And so on. Are we leaping to an unjustified conclusion when we lay a significant part of the blame for obesity, chronic disease and the dramatic rise in reported food allergies at the door of processed food? There are several grounds for examining this connection. Food manufacturers combine ingredients that do not occur in natural food, notably the trilogy of sugar, processed fat and salt, in their most quickly digested, highly refined, nutrient-depleted forms.
The official line — that the chemicals involved pose no risk to human health when ingested in small quantities — is scarcely reassuring. Safe limits for consumption of these agents are based on statistical assumptions, often provided by companies who make the additives. Manufactured foods often contain chemicals with known toxic properties — although, again, we are reassured that, at low levels, this is not a cause for concern.
Nor was he exposed to synthetic chemicals as we are now, in traffic fumes, in pesticides, in furnishings and much more. Real world levels of exposure to toxic chemicals are not what they were during the Renaissance. The processed food industry has an ignoble history of actively defending its use of controversial ingredients long after well-documented, subsequently validated, suspicions have been aired.
If it did, then steering clear of manufactured products would be a lot easier. The pace of food engineering innovation means that more complex creations with ever more opaque modes of production are streaming on to the market every day. Just last month, a dossier for a new line of dairy proteins dropped into my mailbox. How clever. But I would prefer that my bread was browned solely from the application of heat. Not without a fight. Added vitamins One-dimensional factory versions of natural vitamins found in whole foods: ascorbic acid man-made vitamin C is usually synthesised from the fermentation of GM corn, while artificial vitamin E is commonly derived from petrol.

Consumers, food manufacturers and health professionals are uniquely influenced by the growing popularity of the gluten-free diet. Consumer expectations have urged the food industry to continuously adjust and improve the formulations and processing techniques used in gluten-free product manufacturing. Health experts have been interested in the nutritional adequacy of the diet, as well as its effectiveness in managing gluten-related disorders and other conditions. In this review, we aim to provide a clear picture of the current motivations behind the use of gluten-free diets, as well as the technological and nutritional challenges of the diet as a whole. Alternative starches and flours, hydrocolloids, and fiber sources were found to play a complex role in mimicking the functional and sensory effects of gluten in gluten-free products.

Food additives have been used for centuries to improve and preserve the taste, texture, nutrition and appearance of food. The U. Food and Drug Administration evaluates the safety of food additives and determines how they may be used in the food supply. If an additive is approved, the FDA issues regulations that may include the types of foods in which it can be used, the maximum amounts to be used and how it should be identified on food labels. Ingredients that either maintain or control the acidity or alkalinity of foods are known as pH control agents. Citric acid, acetic acid and sodium citrate are widely used agents and often are found in gelatins, jams, ice cream and candies. Lactic acid is an acidity regulator used in cheese-making, and adipic acid can be found in bottled fruit-flavored drinks. Anti-caking agents are added to powdered or granulated ingredients — such as powdered milks, egg mixes, sugar products, flours and baking mixes — to prevent lumping, caking or sticking.
Food Additives and Processing Aids used in Breadmaking
Deciding what foods to buy was simpler when most food came from farms. Now, factory-made foods have made chemical additives a significant part of our diet. And don't forget to cut back on sugar and salt, which cause more harm than all the other additives combined.

A Review on the Gluten-Free Diet: Technological and Nutritional Challenges
All-Purpose Flour — This is a wheat flour that is made from the milling of hard wheat or a mixture of hard and soft wheat. It can be bleached or not and is often enriched with iron and the vitamins folic acid, riboflavin, folic acid, niacin. All-purpose flour is commonly used in homes for noodles, cookies, cakes, quick breads, pastries, and certain yeast breads. Amaranth Flour — Amaranth flour is milled from amaranth seeds, and since it lacks gluten, it can only be used in yeast breads if it is combined with a wheat flour. Many people enjoy this flour due to its strong flavor that is particularly well suited for savory pastries or breads. It also gives quick breads a smooth texture. Ascorbic Acid — More commonly known as vitamin C, ascorbic acid is added to bread flour because it enables bread dough to gain a greater volume when it is baked into a loaf. Baking — Baking is the process of using dry heat to cook food. It is usually performed in an oven.

The main processing aids used are enzymes. Historically, market trends have developed from the use of ingredients in greater quantities - to obtain specific effects in bread such as fat for crumb softness - to the use of additives at much lower levels max. We will describe the food additives used under each class, individually describing their mode of action and effects on dough rheology, during the breadmaking process, and on product quality. We will also describe the main enzymes currently used, dividing them according to the substrate they act on gluten, starch, lipids, non-starch polysaccharides or NSPS , individually describing their mode of action and effects on dough rheology, during the breadmaking process, and on product quality.
