Abstract

Purpose

The purpose of this study is to examine the effect of calcium-rich ingredients such as sesame, skimmed milk powder, moringa leaves, cumin seeds and finger millet on flour, dough and breads with the objective of developing bread with higher calcium content and to investigate whether it maintains quality traits that guarantee its acceptability by consumers by testing textural, scanning electron microscopy and nutritional and sensorial parameters.

Design/methodology/approach

Refined flour was fortified with skimmed milk powder (SMP), sesame, moringa leaves and cumin (T1), SMP, sesame and malted finger millet (T2) and SMP and sesame (T3). Refined flour dough and breads served as control (C). The physicochemical, textural, scanning electron microscopy, nutritional and sensory parameters of flour, dough and breads were evaluated.

Findings

Significantly (p < 0.01) higher stickiness values of dough were obtained by refined flour dough-C (50.3 N); refined flour dough fortified with SMP and sesame - T3 (42.2 N); Refined flour dough fortified with sesame, SMP and malted finger millet -T2 (38.4 N); and refined flour dough fortified with sesame, SMP, moringa leaves and cumin -T1 (33.5 N). Oven spring in breads was 1.4 in C and decreased significantly (p < 0.01) to T3-1.0, T1-0.9 and T2-0.8. Chewiness values of T3 (4.1) was similar to C bread, whereas T1 and T2 showed significantly (p < 0.01) lower values. Scanning electron microscopy images of bread microstructure showed fortification of bread resulted in intermittent but more prominent gluten structure in test breads than control. The highest calcium content was observed in T1 (268 mg/100 g), followed by T2 (231 mg/100 g) and T3 (211 mg/100 g). The incorporation of dried moringa leaves and cumin seeds enhanced the appearance, aroma, taste and flavor of T1.

Research limitations/implications

The study shows that texturally and sensorially acceptable nutritious breads can be produced through natural fortification. Nutrients from naturally fortified foods are better absorbed and assimilated by the body. Calcium-fortified breads, each with its own distinctive taste and texture, showed high values in the sensory evaluation test.

Originality/value

The incorporation of calcium and protein-rich ingredients such as SMP, moringa leaves, cumin, malted finger millet and sesame would yield calcium enriched breads superior to the commonly consumed plain refined wheat flour bread with respect to textural, nutritional, functional and sensory attributes and have high potential to alleviate calcium deficiency in vulnerable groups.

Abstract

The formulated proposals for this legal principle in the trade battern of the European Community have again appeared in the EEC draft Directive. It has been many years in coming, indicating the extreme difficulties encountered in bringing some sort of harmony in the different laws of Member‐states including those of the United Kingdom, relating to the subject. Over the years there were periods of what appeared to be complete inactivity, when no progress was being made, when consultations were at a stand‐still, but the situation was closely monitored by manufacturers of goods, including food and drink, in the UK and the BFJ published fairly detailed reviews of proposals being considered — in 1979 and 1981; and even as recently as the last few months — in “Consumerism in the Community”, the subject was briefly discussed.

Abstract

Purpose

As natural dietary sources of vitamin D are not consumed in sufficient quantities, fortified foods could play a role in maintaining vitamin D sufficiency. With public consultation, an integral part of designing acceptable fortification strategies, the purpose of this paper is to understand public awareness and perception of vitamin D fortified foods.

Design/methodology/approach

A mixed-methods approach was taken with two focus groups and 109 surveys conducted using a non-probability sample from North-East England. Thematic analysis of focus group data identified six themes, with factor and cluster analysis identifying seven factors and four clusters, respectively, which highlighted differences in vitamin D knowledge and fortified food perceptions.

Findings

Despite identifying sunlight as the main vitamin D source (91 per cent), participants were less aware of the main dietary source (33 per cent), and few could state fortified products (51 per cent). Although attitudes towards fortification were generally favourable (63 per cent agreeing that selected products should be fortified), nearly half (43 per cent) were unsure if more products should be made available. Results suggest that more natural products to complement existing market offerings would be most preferred. Factor and cluster analysis results identified awareness of health benefits and/or dietary sources as essential to have favourable attitudes towards fortified products.

Originality/value

This research adds to the limited literature regarding consumer attitudes towards fortified foods. It highlights a need to improve public awareness and labelling of fortified products to potentially increase fortified food consumption.

Abstract

The report recently issued by the Department of Health and Social Security entitled Nutritional Aspects of Bread and Flour should be required reading for all concerned with the planning of healthy diets. Detailed evidence gathered by the Panel on Bread, Flour and other Cereal Products of the Committee on Medical Aspects of Food Policy (COMA), concerning the composition, nutritive value and physiological effects of cereal foods is presented and discussed, and the recommendations reached on the basis of that evidence could, if accepted, have considerable effects on the national diet. ‘If accepted’ is stressed because the recommendations have yet to be endorsed, either entirely or in part, by the Minister responsible for food, after consultation with his advisers and other interested bodies including the milling and baking industries. The necessary legislation would then have to be drafted, circulated for comment, and laid before Parliament for approval. Some delay is therefore inevitable before modifications of the legislation establishing the composition of bread and flour become effective.

Abstract

Three events of significance to this country took place in 1899 – the British Food Journal was launched, Australia retained the Ashes, and the Boer War hostilities commenced. If challenged on the order of their importance, cricketers and Empire‐builders may be excused their preference. However, looking at it purely from the standpoint of pro bono publico, the dispassionate observer must surely opt for the birth of a certain publication as being ultimately the most beneficial of the three.

Abstract

Purpose

Inadequacies in several micronutrients in complementary foods, notably iron, zinc, calcium, vitamin A, vitamin B6 and riboflavin have been reported. Moringa oleifera leaf powder (MLP), prepared from dried moringa leaves is nutrient-rich and has been explored for the treatment of micronutrient deficiencies among children in developing countries. This increasing interest in the use of moringa oleifera leaves to improve complementary foods notwithstanding, the unique sensory characteristics of the leaf powder potentially holds implications for the acceptability of local diets that are fortified with it. The purpose of this paper is to investigate the levels of MLP fortification that are most acceptable for feeding infants and young children.

Design/methodology/approach

The authors performed a review of the literature, with the aim of investigating the sensory attributes and acceptable levels of fortification of complementary food blends fortified with different levels of MLP.

Findings

The minimum amount of MLP to be added to a complementary food blend to observe significant improvements in its nutritional value was estimated to be about 10 per cent. However, at this 10 per cent fortification level also, sensory attributes of the products begin to become less desirable.

Practical implications

For the success of nutrition interventions that involve the use of MLP to improve the nutritional quality of complementary foods, there is a need to consider the acceptability of the sensory attributes of the formulated blends in the target group. Safety of MLP as an ingredient in infant foods must also be investigated.

Originality/value

The authors of this paper make recommendations for the use of MLP to fortify complementary foods to ensure its success as a food fortificant in nutrition interventions. The researchers are not aware of any published study that focuses on this subject.

Abstract

Purpose

The enrichment of bread with non-digestible prebiotic ingredients may exert health-promoting effects and provide healthier food choices for those suffering from metabolic diseases, including obesity and diabetes. The purpose of this study was to investigate the effects of ß-glucan and resistant starch incorporation on the glycemic index (GI) and glycemic load (GL) of white bread.

Design/methodology/approach

Seven different formulations of prebiotic bread were produced using different proportions of ß-glucan (0.8, 1 and 1.2 per cent), resistant starch (5.5, 8 and 10.5 per cent) and the combination of resistant starch and ß-glucan in a ratio of 4:0.5.

Findings

The GI and GL of the prebiotic bread prepared with 1 per cent ß-glucan (w/w) were 55.7 and 7.8, respectively, whereas those of the prebiotic bread prepared with 8 per cent resistant starch (w/w) were 64.8 and 8.42, respectively, with both breads having significantly lower GI and GL values than the control (P < 0.05). It was concluded that the incorporation of 1 per cent ß-glucan may be beneficial in producing prebiotic bread with both low GI and low GL.

Originality/value

Although white bread is a main food source in human diet, its high GI and GL make it an unhealthy food choice. The incorporation of ingredients with prebiotic effects, such as ß-glucan and resistant starch, can improve the nutritional value of this product by lowering its GI and GL.

Abstract

Purpose

Vitamin D deficiency is a well-recognised public health problem within the UK, with specific population groups more vulnerable to deficiency. Two pilot studies were used to explore awareness of vitamin D deficiency and attitudes towards food fortification.

Design/methodology/approach

A survey of 120 participants from five at-risk groups (South Asians, Blacks, Middle Eastern, Far Eastern and Caucasian older adults over 65 years) plus a group of British Caucasians who do not avoid sun exposure explored awareness of vitamin D, sun exposure knowledge and behaviour and attitudes towards food fortification. The latter group was included to provide a comparison group who were at a reduced risk of deficiency. χ2 was used to test associations between categorical variables and the study groups. The second study used three focus groups and two interviews, conducted on young South Asian females and examined knowledge and awareness of vitamin D and vitamin D-fortified foods.

Findings

A lack of knowledge and misconceptions were highlighted by both studies in relation to at-risk factors, including sunlight exposure (p = 0.037), dietary intakes (p = 0.0174) and darker skin pigmentation (p = 0.023), sources of vitamin D and the health benefits associated with optimal consumption. Attitudes to mandatory fortification of some foods varied significantly (p = 0.004) between the groups with acceptance rates for Blacks (68 per cent), those over 65 years (50 per cent), Middle Eastern (67 per cent) and Far Eastern (73 per cent), whereas the control (71 per cent) showed no acceptance, and South Asians gave a mixed response (48 per cent No). Focus group findings highlighted positive views towards fortification, although this was less for mandatory as opposed to voluntary fortification. Both pilot studies highlight the need for more research into this area, to create more effective public health policies.

Originality/value

The research presents novel insights into a topical area where there is limited research.

Abstract

The addition of nutrient factors, vitamins, minerals, etc., to food to enrich or restore deficiencies in normal concentrations is considered by most people to be a commendable practice, in quite a different category to other food additives, which have little or nothing to do with nutrition and are used mainly for commercial purposes.

This study aims to assess the exposure of Lebanese consumers to nutrition and health claims (NHCs) on pre-packed bread.

Abstract

Purpose

This study aims to assess the exposure of Lebanese consumers to nutrition and health claims (NHCs) on pre-packed bread.

Design/methodology/approach

Bread samples (n = 354) from all the bakeries (n = 44) located in Mount Lebanon, between 2017 and 2018, were assessed. Breads with nutrition claims were analyzed using standard methods. A cross-sectional study was also conducted among 400 supermarket shoppers.

Findings

Results showed that among the collected samples of bread (n = 354), 59.6 per cent carried at least one claim, 47.2 per cent had non-nutrient claims, 32.5 per cent had nutrition claims and 15.3 per cent presented health claims. Claims related to sugar, salt and fiber content were the most commonly used (28.8 , 16.4 and 14.7 per cent, respectively). NHCs were mostly present on whole wheat bread. Breads with claims were more expensive. Half of the participants (49.8 per cent) relied on NHCs whenever purchasing bread, especially females (OR = 2.35, 95 per cent CI = 1.44-3.84, p = 0.001), those following a specific diet (OR = 4.56, 95 per cent CI = 2.02-10.25, p < 0.001) and those with the lowest household income (OR = 0.795, 95 per cent CI = 0.639-0.989, p = 0.040).

Originality/value

The overall findings showed that Lebanese consumers are highly exposed to NHCs, especially those at higher risk which could lead to serious public health issues if their use is not strictly regulated and controlled. Moreover, NHCs could be used as a tool to increase consumers’ awareness and help them make healthier choices during shopping.
