The nearly ubiquitous consumption of cereals all over the world gives cereals an important position in international nutrition. Besides the high starch content as energy source, cereals provide dietary fibre, nutritious protein and lipids rich in essential fatty acids. Important micronutrients present in cereals are vitamins, especially many B vitamins, minerals, antioxidants and phytochemicals. In general, cereals provide important amounts of most nutrients. However, processing may decrease or increase the levels of the bioactive components in grains and also modify the bioavailability of these components. In addition, interactions between bread and companion foods have effects on the nutritional quality. The aim of this paper is to review the existing literature on the effects of processing techniques and interactions with other food components in a mixed meal on the nutritional quality of bread. Furthermore, research findings on the consumer perception of bread in Belgium are included. This information can help health professionals and policy-makers to give clear and targeted advice about the positive effects of bread in the human nutrition during consultations and information campaigns.

    • "activity and low pH in the bread pulp; however, under favourable development conditions; higher amounts of spores outgrow into vegetative cells and cause ropiness spoilage. Bread defects can cause huge economic losses for bakery industry (Thompson et al., 1998; Dewettinck et al., 2008). In order to prevent the development of ropiness defect in wheat bread, it is necessary to determine what level of bread contamination by aerobic spore-forming bacteria can cause the defect of ropiness, and what impact in this regard could have the duration of bread storage and temperature.

    ABSTRACT: Abstract The aim of the study was to determine the level of contamination of white bread by aerobic spore-forming bacteria that may cause the ropiness and to evaluate the antimicrobial activity of lactic acid bacteria against aerobic spore-forming bacteria during the storage of wheat bread at different temperatures. The contamination of dough samples by aerobic spore-forming bacteria did not affect the quality of bread in the initial storage phase (6–16 h after baking). The critical Bacillus subtilis subsp. spizizenii ATCC 6633 levels that cause ropiness in baked bread were determined: 7.8 × 106 CFU (colony forming units) g-1 after storage of samples for 3 days at 2 ± 2°C, 1.3 × 106 CFU g-1 after storage of samples for 3 days at 18 ± 2°C and 6.0 × 106 CFU g-1 after storage of samples for 1 day at 30 ± 2°C temperature. It was determined that contamination of dough by aerobic spore-forming bacteria should not exceed 1.0 × 103 CFU g-1. The evaluation of antimicrobial activities of lactic acid bacteria from Lactococcus and Lactobacillus genera against aerobic spore-forming bacteria was performed using an agar well diffusion method. In wheat bread, that had been fermented with Lactobacillus delbrueckii subsp. bulgaricus 148/3, L. acidophilus 336 and L. casei subsp. casei, the antimicrobial effects were observed for up to 3 days of storage at 18 and 30°C temperature. Weak signs of ropiness spoilage (sweet rope odour, discoloration of the crumb) were observed during the storage of the bread samples at 18 ± 2°C for 5 days (1.7 × 102 CFU g-1) and at 30 ± 2°C for 3 and 5 days (1.5 × 102 CFU g-1).

    ABSTRACT: Over the 2000s', consumers' food purchases have been increasingly informed by supply chain-related issues, with growing concerns about the sustainability of chains differing for their geographical scope. As a result, short food supply chains and local food systems have risen to policymakers and food chain stakeholders' attention as more sustainable alternatives to mainstream food networks. However, associating food chain's geographical scope and sustainability performance may not be straightforward. This paper aims at shedding lights on the connection between geographical scope and sustainability by comparing and discussing 19 attributes owing to different sustainability dimensions. The analysis anchors on the wheat-to-bread chain, due to its global relevance. Bread is a worldwide staple food and wheat is (generally) a commodity traded globally. However, wheat processing often occurs locally and baking is influenced by local heritage and consumption patterns, particularly in the EU and in Italy, where gastronomy is culturally embedded. The paper identifies critical aspects and provides a qualitative assessment of the performances of local vs global wheat-to-bread chains. The assessment is carried out on Italian case studies.

    • "Bread may be described as a fermented confectionary product produced mainly from wheat flour, water, yeast and salt by a series of process involving mixing, kneading, proofing, shaping and baking (Dewettinck et al., 2008). Bread has been a major component of human diet dating back to pre-historic man. "
