How Long Does Bread Last?
Bakery wastes are a combination of different wastes, and their composition is thus highly variable McGregor, Bakery wastes are extensively used as feed for farm animals which reduces their disposal and alleviates environmental issues Westendorf et al.
Any bakery waste can be used on farm provided it does not contain meat, fish or shellfish. Bakery wastes may also provide valuable and readily hydrolisable feedstock for industrial fermentation Magbunua, Baking bread is done since the beginning of the Roman Empire. Bakery is now a major food industry in the world and varies widely in terms of production scale and process GIA, ; Chandrasekaran, Europe is the largest market expected to slightly decrease.
The European volume of bread was Asia is the fastest growing market, with its population shifting from rice based diet to wheat food based products. It would become greater than the European market by Bakery wastes are produced at every stages of production. In , in the USA, the amount of bakery wastes was reported to represent 5. Bakery wastes have a long history as feeds. In , bread and dough residues were already recommended for livestock feeding as they were a source of more digestible energy than raw flour Cornevin, When bakery wastes are intended for animal feeding, the problems relate primarily to animal health concerns, moisture content, and nutrient variability.
It is important to properly process bakery waste for feed safety. A broad range of processes such as extrusion, dehydration, pelletisation or silage of bakery wastes have been assessed in order to have good preservation and storage of the resulting feedstuffs. Waste processing depends on the nature of the waste. Bakery wastes are considered to be safer than other food wastes. The process is shown in the video below.
Another way to preserve bakery waste is to ensile it. Bakery waste could also be ensiled in mixture with other grocery waste Froetschel et al. Bakery waste is a highly variable product. Sugar and starch contents are also highly variable, as are mineral particularly sodium and energy contents Arosemena et al. Bakery waste, such as stale bread and crumbs, can be dried and mixed for animal feeding. It is rich in fat and carbohydrates, but the protein quality and the vitamin content are low.
It has been used as a substitute for grain in rations for all classes of livestock. When bakery waste is fed in large amounts, it must be supplemented with vitamin A, minerals and good-quality protein. Bakery waste may have a high salt content McGregor, Bakery wastes are prone to molds. Feeding rotten bakery wastes to livestock is detrimental. In , it was reported to cause nervous disorders, anormal salivation, increased heart beat frequency, blindness and even death in growing pigs and horses Cornevin, The EFSA reported that cereal products, among which bread and fine bakery wares, made the largest contribution to the estimated zearalenone exposures.
Zearalenone is a mycotoxin produced by a cereal fungus of the Fusarium genus. Pigs are particularly sensitive to zearalenone that has several oestrogenic effects EFSA, Clinical signs of botulism were lower feed intake, malodorous faeces, progressive weakness, ataxia, recumbency, and death. Out of animals, 52 were ill and 14 died. The bakery waste was considered the likely source of the toxin and was found positive for the presence of Clostridium botulinum type D. Two days after the removal of bakery waste from the diet, there were no new reported cases of botulism in the feedlot Heider et al.
This was the unique case of Clostridium botulinum contamination of bakery waste. Toxin discharge probably occurred since heavy rains provided suitable anaerobic conditions for Clostridium previously present in bakery waste Heider et al.
Bakery waste can be used to feed ruminants. Due to its high concentration of non-fibrous carbohydrates and its relatively low crude protein content, it can be used as an energy concentrate that has to be supplemented with a source of protein Waldroup et al.
Although dried bakery waste are reported to be included in feeds intended for dairy cows, feeding value of bakery waste has been mainly evaluated in growing lambs and steers Arosemena et al. Inclusion of this by-product in the diet of these animals could be an interesting way to reduce feed costs Hindiyeh et al. In fattening lambs, bakery wastes have been used in substitution of maize Oliveira et al. In those conditions, inclusion of bakery wastes in substitution of maize grain had no effects on nutrients intake, digestibility, and body weight or meat composition of fattening lambs Mahmoud, ; Santos et al.
When bakery wastes were used to replace barley, results were more contrasted, most probably due to the variability of bakery waste and experimental conditions Hindiyeh et al. Linolenic fatty acid content of meat was increased with increasing inclusion of bakery waste likely because of the high soluble sugar content of this feed Afzalzadeh et al. They had lower growth rate, lower slaughter weight and longer time to slaughter. In India, growing crossbred pigs could be fed on bread waste during 3 months, in order to replace maize in their diet.
The authors confirmed that including bread waste was economically effective Kumar et al. Bread waste also decreased cooking losses by 3. Saturated fatty acids increased while unsaturated fatty acids were reduced and examined for meat quality Iwamoto et al.
Feed intake was also reduced due to a decrease in feed choice Kumar et al. Similarly it was shown that a traditional pig diet based on bread waste was less effective than other traditional feeds based on kitchen waste or cooked poultry offal Chakurkar et al. Bakery waste is well adapted to poultry nutrition. Due to its variable composition, feed formulation should be adapted to the real composition of the product used, in particular protein and fat content.
Economic gain associated to the use of bakery waste in poultry was underlined by several authors Al-Ruqaie et al. Bakery waste can be used in broiler diets without affecting growth, feed intake and feed efficiency Damron et al. No effect of enzyme supplementation was recorded, neither on performance nor on nutritional or energy value Boros et al. Bakery waste is suitable for layers.
Total replacement of maize was even possible without adverse effects on production Torki et al. Enzyme supplementation had no effect on production Torki et al. Stale bread or bakery wastes are traditionally used to feed rabbits in small familial units and backyard systems around the world, together with other kitchen, garden or market wastes Rastogi, ; Degen et al.
In balanced diets, bread wastes may completely replace cereals with interesting economical results Al-Shami et al. The digestible energy content was estimated between The diet had no deleterious effect on fish growth Carratore et al.

List of baked goods
Baking is a method of preparing food that uses dry heat, normally in an oven , but can also be done in hot ashes , or on hot stones. The most common baked item is bread but many other types of foods are baked. As heat travels through, it transforms batters and doughs into baked goods and more with a firm dry crust and a softer centre". Baking is related to barbecuing because the concept of the masonry oven is similar to that of a smoke pit.
The aim of this work was to evaluate the effect of the addition of citrus fibers, from blood orange and lemon peels to produce a functional durum wheat bread. No significant differences were observed with respect to the specific volume and weight, internal structure, pH and titratable acidity among the bread samples obtained using different types and percentages of fibers. Storage time, at 30 up to 90 days, affected significantly the bread firmness and caused significant differences in 5-hydroxymethylfurfural HMF levels in all bread samples. The results of the sensory evaluation highlight that loaves enriched with blood orange and lemon fibers showed a citrus flavor but had a similar overall evaluation respect to control bread produced without addition of citrus fiber. Dietary fiber have an important role in maintaining good health and prevention of disease.
By Patricia Marden, B. Baked goods may range from those prepared in manufacturing facilities and sold at retail stores to specialty baked items prepared and sold in the stores themselves. Both manufacturing facilities and bakery stores share common food safety challenges and require the proper design of food safety programs to minimize the risks inherent in bakery products and their production environment. Food Safety Challenges of Baked Goods There are several factors to consider when evaluating food safety risks in retail bakery products. First, product assortment and storage conditions must be understood. For example, products with pH and aw above 4. Several bakery products have been implicated in foodborne illnesses involving Salmonella spp.
Tesco upcycles surplus bread to combat food waste: Who else is doing their part?
There is increasing emphasis on reformulating processed foods to make them healthier. This study for the first time comprehensively investigated the effects of fortifying bread containing oil as an ingredient with freeze-dried vegetables on its nutritional and physico-chemical attributes. Breads fortified with carrot, tomato, beetroot or broccoli were assessed for nutrition, antioxidant potential, storage life, shelf stability, textural changes and macronutrient oxidation. Furthermore, using an in vitro model the study for the first time examined the impact of vegetable addition on the oxidative stability of macronutrients during human gastro-intestinal digestion.

Proper storage of ingredients and baked goods is essential to keeping food fresh and tasty and not risking foodborne illnesses. Then, they must be refrigerated after baking. Eggs and milk have high protein and moisture content and when these baked products are left at room temperature, conditions are ripe for bacteria to multiply.
Food waste is a major concern. These lost food products, wasted in households, hospitality and food service, food manufacture, retail and wholesale sectors, are associated with more than 25m tonnes of greenhouse gas emissions. According to sustainability experts WRAP, which calculated these estimates, surplus bread is one of the biggest waste problems facing food retailers. In an effort to reduce these figures, UK supermarket retailer Tesco is upcycling surplus baguettes and batons into new bread pudding and olive oil crostini products.
Wheat has accompanied humans since remote times as far back as to BC in their evolution and development, evolving itself in part by nature and in part by manipulation from its primitive form emmer wheat into the presently cultivated species. The more important modern wheat species are hexaploid bread wheat Triticum aestivum L. Except for the very warm tropics, wheat adapts to all diverse climatic conditions prevailing in agricultural lands and, therefore, it is harvested in the world all year around. Its wide adaptation to diverse environmental conditions, along with its unique characteristic of possessing a viscoelastic storage protein complex called gluten, are the main factors making wheat the most important food crop in the world.
Gluten-free GF batters usually present several technological challenges that limit the performance during conventional baking and the resulting product quality. Due to the volumetric heating principle and faster heating rates, ohmic heating OH may be advantageous compared with conventional baking. Therefore, the potential of using ohmic heating as a novel approach for gluten-free bread baking was explored. In detail, the effect of different OH process parameters power input, holding time on the chemical and functional properties specific volume, crumb firmness and relative elasticity, pore properties, color, starch gelatinization and digestibility of breads was investigated. Results showed that GF breads could benefit from the uniform rapid heating during processing, as these breads showed superior functional properties specific volume, 2.
