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.

However manufacturers may present their reasons in terms of consumer demand, their motivation for adulterating their products is basically generating greater profit. Click here for more on additives, including a category known as processing aids that don't even have to be declared on the label.
Because of the multiplier effect, it has been calculated that, as a result, local spending contributes around four times as much to the local economy as spending with non-local businesses. The importance of such re-localisation of business, particularly in areas of disadvantage, is summarised in the National Strategy for Neighbourhood Renewal :.
Rather it is what consumers, public services and businesses do with that money. Too often it is spent on services with no local presence, and so immediately leaves the area.
Local bakers also provide a way of preserving traditional baking skills that are otherwise at risk of being lost, and can provide a focal point in local communities where other services have been lost. In part, this means an ongoing drive to keep staffing levels to an absolute minimum.
Taken to a national level, the demand of approximately 12 million loaves a day would support 25, small bakeries each employing three people — offering a total of 75, skilled jobs for local people. Treating a product to prolong artificially the characteristics of freshness is effectively loaf botox. Just as a chemical facelift does not change a person's age, a ten day old loaf that is made using processing aids to prolong softness, pumped full of salt and sprayed with a fungicide to inhibit the growth of mould, is still a ten day old loaf.
It should be noted that certain sourdough Real Breads will keep for a week or more, the products of the fermentation process acting as natural preservatives.

There are many reasons why a loaf of Real Bread baked by a local, independent bakery might differ in price from an industrial loaf or supermarket in-store 'bakery' baguette. For a particular bakery these might include:. For more thought on the real value of Real Bread and true costs of other alternatives, click here.
Something else to ponder is: Why might a supermarket charge around three times more for a 'premium' white-sliced loaf than for its apparently nearly-identical 'value' one manufactured using similar ingredients and processes? If price at the till is your main consideration, baking your own Real Bread at home either by hand or in a machine could well be cheaper than even the cheapest supermarket loaf. It is commonly used on what are termed 'known value items' - products of which shoppers tend to know the price.
Some shoppers will base their opinions of retailers overall pricing on just a few KVIs - 'milk, loaves and bananas are cheaper here at Safeburys than Tescisons up the road Most modern British recipes call for strong or bread making flour.
This is what flour that has high levels of gluten, the stretchy protein that traps bubbles of carbon dioxide and allows them to expand, causing bread to rise.
You can make bread with lower protein flours and indeed some styles of bread e. And if you purchase either direct or from a locally owned retailer, more of your cash is likely to be re-invested in that local community. Click here for notes on finding independent mills. Modern roller milling is ruthlessly efficient at stripping away the nutrient rich outer layers of wheat grains, leaving behind not much more than starch and gluten.
Additionally, the heat generated by the process actually destroys some of the compounds. Compared to whole wheat, refined white flour is highly depleted. Example losses are:. In recognition of the fact that roller-milled white flour is so nutritionally depleted, since the 's UK law has demanded that calcium, iron and vitamins B1 and B3 be added to all British milled breadmaking flour except wholemeal in an attempt to compensate for some of the shortfall.
There is still, however, a whole range of minerals, vitamins, antioxidants and phytonutrients that are not replaced at all during this ' fortification '. White flour is much lower in fibre than wholemeal. The simple grinding of the whole grain in a single pass through and between two horizontal, round millstones is at the heart of traditional milling.
It is designed to produce wholemeal flours with excellent flavour and nutritional value. Unlike roller milling, which removes the outer layers of the grain, stone milling crushes the grain and all parts are mixed in together. Even when finely sifted to produce lighter coloured flours, they will still contain fine particles of the fibrous and most nutritious parts - the germ and bran.
There has also been research to suggest that the heat generated by roller milling destroys greater percentages of nutrients in comparison to stone ground flours of equivalent extraction rates. The Real Bread Campaign calls for more research to be done on the beneficial effects of longer fermentation, especially in the presence of sourdough bacteria.
Real Bread is a natural product and just as with fruit or cheese it takes time for it to ripen. Although research so far has been limited, there is growing evidence that leaving dough to rise for longer periods can have a range of benefits to the consumer.
Examples include:. One of the problems with these are that they may well have been produced using the same processing aids and additives as the dreaded white sliced loaf. A further reason is that the weight and size of chilled dough or a part-baked loaf are greater than those of the flour used to make them. It therefore takes more energy to transport dough or bread than flour or grain. For more on this issue, please see our report Are Supermarket Bloomers Pants?
Bread can be made without salt, the traditional breads of Tuscany are an example, but many people in the UK would find bread made without any salt at all to be bland. That said, to boost the three effects above, industrial bread often has very high levels of salt, as can be seen in these articles from the BBC and The Daily Telegraph.
In , many Real Bread bakers told us that they do so already. Click here to read more. For much more on salt in bread, click here. Unless you have an allergy or intolerance to baker's yeast, there is nothing wrong with it. You can make great Real Bread with baker's yeast. None of this has been proven beyond doubt and the Real Bread Campaign calls for more research to be done on the potentially beneficial effects of sourdough fermentation.
Given the growing body of evidence examples below , not to mention the number of their own customers who may have reported positive experiences, this is understandable.
None of these relates to sourdough. Over many hours of slow fermentation, lactic acid bacteria LAB produce lactic and acetic acids and other compounds which research suggests may perform a remarkable number of useful tasks, such as:. Providing an environment favourable to the production of phytase. Cereal bran contains phytic acid, which inhibits the body's ability to absorb certain nutrients — e. Phytase breaks down the phytic acid, allowing the body to absorb more of those nutrients. Nutrition, Volume 19, Issue 6, June , Pages Reducing the levels of phytic acid This is the main form in which plants especially seeds and pulses store phosphorus, but it combines with certain minerals including calcium, zinc, magnesium and notably iron in a way that makes the human body unable to absorb and make use of them.
Leenhardt, F. Moderate decrease of pH by sourdough fermentation is sufficient to reduce phytate content of whole wheat flour through endogenous phytase activity. Food Chem. Counteracting the potentially negative effects of certain things that can be found in dough and bread, e.
Modifying or eliminating the protein fractions especially certain gliadins that are responsible for triggering wheat intolerance and coeliac disease: Di Cagno, R. Sourdough bread made from wheat and non-toxic flours and started with selected lactobacilli is tolerated in coeliac sprue patients. Pakistan Journal of Nutrition 6 6 : , A blend of bacterial culture along with baker's yeast can give better performance for better quality and shelf life of the bread.
Faqir M. Issa Khan, M. For example: 'The amount of GABA in g of Pane di Matera PGI [an Italian sourdough culture] represents the minimum effective daily dose to achieve a lowering of blood pressure in mild hypertensives.
Subjectively, sourdough fermentation improves the flavour, aroma and texture of bread, especially rye. According to Diabetes UK :. With thanks to Diabetes UK for pointing us towards the following, here are some studies that show the positive effects of sourdough fermentation on the Glycaemic Index GI of bread. Sourdough - leavened bread improves postprandial glucose and insulin plasma levels in subjects with impaired glucose tolerance Acta Diabetologica,Volume 45, Number 2, The acute impact of ingestion of breads of varying composition on blood glucose, insulin and incretins following first and second meals British Journal of Nutrition , , — Use of sourdough lactobacilli and oat fibre to decrease the glycaemic index of white wheat bread British Journal of Nutrition , 98, — Epub Aug A dietary exchange of common bread for tailored bread of low glycaemic index and rich in dietary fibre improved insulin economy in young women with impaired glucose tolerance European Journal of Clinical Nutrition 60, — Some people have genuine medical conditions that cause them to have adverse reactions to certain foods.
Individual responses vary, and so whilst one person might not be able to eat any cereal containing gliadin a type of protein that combines with glutenins to form gluten in wheat, and is also found in other cereals, such as barley and rye , another might have problems with modern wheat Triticum aestivum but not with spelt Triticum aestivum var.
Some people have trouble with avenin a protein similar to gluten in oats. The Real Bread Campaign recognises how hard it is for them to find Real Bread made without gluten, particularly if they are seeking a white sandwich loaf.
Coeliac disease is not a food allergy or intolerance: it is an auto-immune disease that is triggered by the omega 5 gliadin proteins found in cereals including wheat spelt is a type of wheat , barley and rye.
Some coeliac sufferers also cannot eat oats. In common with other auto-immune diseases including rheumatoid arthritis this causes the body to attack itself. In the case of coeliac disease, the immune system produces antibodies that attack the lining of the digestive system, sometimes resulting in perforation of the stomach or intestines.
The Coeliac Society estimates that the disease affects around 1 in people in Britain. An allergy is a condition that causes the body mistakenly to recognise a substance —such as gluten - as toxic and produce histamine in defence. The body then reacts to the histamine in any number of ways, including rashes and breathing difficulty.
When it comes to baking healthy bread, the simplest way to boost nutrition is to use whole-grain flours. Bread, like most foods, is generally healthier when made with whole, unprocessed ingredients without a lot of additives. I'll show you how to choose which flours and other ingredients are best for making healthy breads, and how to work with them so your bread turns out just right. I'll also point you to top-rated bread recipes that are packed with nutrients and taste great, too. When whole grains are milled into refined flour, the bran and germ are removed, leaving only the endosperm.
What is Enriched Flour?
Sourdough has become more and more popular—but is it really better than a slice of white? Photo: Prospect composite. Brick House loaves are handmade with organic flour, slow-fermented, naturally leavened and stone-baked over a period of around 48 hours in their converted east Dulwich warehouse. The hum of commuters trundling into the train station next door, like the arrival of the bakery itself in , reflects the rapid gentrification the area has undergone in the last decade. They do not accept cash.
Frequently asked questions
We know unrefined grains are better for us. We know that flour from unrefined grains is made from the WHOLE grain, not just a portion of it, so all of the original nutrition is still intact. Making white flour? Not so easy. Does white flour contain bleach? Oh my my, those are some serious questions. Apparently no one wanted to bake with ugly flour….
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. Legal aspects will also be addressed. We will conclude with future trends in the use of additives and processing aids in breadmaking. Food Additives. Maximum dosages permitted may vary according to the application and from country to country; so local legislation must always be consulted. The International Numbering System, created in the European Union, assigns E-numbers to all approved food additives, and these are used in many countries to facilitate identification. Oxidants and reductants are normally included to assist with gluten network development [ 1 ].

Type a minimum of three characters then press UP or DOWN on the keyboard to navigate the autocompleted search results. Brain cells, muscle, skin, hair and nails are just some of the body parts that are protein-based. Many of the foods we eat contain protein, particularly flesh foods chicken, beef, lamb and fish , and legumes like beans and lentils. These proteins are broken down during digestion to release amino acids, which are the building blocks of all proteins. Once inside the body, these amino acids are used to make new proteins including enzymes and hormones such as adrenalin. Proteins are sometimes also used as an energy source. For example, a 75 kg adult male would need 63 g of protein per day. It is recommended that 15 to 25 per cent of total energy intake per day is from protein sources.
Food fortification or enrichment is the process of adding micronutrients essential trace elements and vitamins to food. It can be carried out by food manufacturers, or by governments as a public health policy which aims to reduce the number of people with dietary deficiencies within a population. The predominant diet within a region can lack particular nutrients due to the local soil or from inherent deficiencies within the staple foods; addition of micronutrients to staples and condiments can prevent large-scale deficiency diseases in these cases. Food fortification has been identified as the second strategy of four by the WHO and FAO to begin decreasing the incidence of nutrient deficiencies at the global level. The WHO and FAO, among many other nationally recognized organizations, have recognized that there are over 2 billion people worldwide who suffer from a variety of micronutrient deficiencies. In Canada, the Food and Drug Regulations have outlined specific criterion which justifies food fortification:. There are also several advantages to approaching nutrient deficiencies among populations via food fortification as opposed to other methods.
HAVE SOME QUESTIONS? WE’VE GOT ANSWERS.
As runners, bread is an integral part of most of our diets, but choosing from the different types can be a little overwhelming to say the least. Instead of spending way too long picking out a loaf of bread at the supermarket, know the facts about bread and how to select one that is right for you. This may seem obvious, but the main ingredient in most bread is wheat. Gluten-free bread is an exception to that rule, since gluten is a protein in wheat. Wheat is an excellent source of carbohydrates , which is the primary fuel source for exercise. Those three components of the grain house the valuable nutrients, such as fiber, protein, B vitamins, iron, zinc, and copper. White bread, on the other hand, is made from refined flour, which has the bran and germ removed. Without those two nutritious parts of the grain, the final refined flour is lacking nutrients such fiber and protein.
This paper covers specific aspects of the use and production of food composition data in the food industry. Two types of information are stored by manufacturers: quantitative information on an extensive list of nutrient and non-nutrient components including contaminants, stored separately , and qualitative information about suitability for diets to reduce or eliminate components. The aim of collecting such information is usually to check product compliance with regulations or internal specifications and norms, with a special emphasis on nutritional labeling. Control of costs, processing, storage stability, taste and texture constraints are important goals along with provision of product information to consumers.
Bread is a staple food prepared by baking a dough of flour and water. The virtually infinite combinations of different flours and differing proportions of ingredients, has resulted in the wide variety of types, shapes, sizes, and textures available around the world.
