Abstract

Purpose

Numerous food recalls and outbreaks were associated with wheat flour in recent years. Few consumers are cognizant of food safety risks associated with raw flour. The purpose of this study is to evaluate the food safety information and flour-handling behaviors presented in popular food blog recipes and in YouTube videos using cookie, cookie dough and egg noodle recipes as examples.

Design/methodology/approach

Eighty-five blog recipes and 146 videos were evaluated. Blog author and video host food-handling experience was classified as professional or nonprofessional. Food safety information and food-handling behaviors were evaluated for adherence to government and scientific recommendations.

Findings

Blog authors and video hosts demonstrated higher awareness of food safety risks associated with raw eggs compared to raw flour, which only translated into better adherence with recommended food-handling behaviors during ingredient addition steps. Cross-contamination from adding raw flour to the product was observed in 25% of videos, whereas cross-contamination from hosts adding raw shell eggs was observed 3% of videos. Blog authors and video hosts did not recommend or demonstrate handwashing after handling raw shell eggs nor raw flour, and fewer than 5% provided recommendations for cleaning work surfaces. Heat treatment methods to convert raw flour into ready-to-eat products were mentioned by 24% of blog authors and 18% of video hosts; however, the recommendations were not scientifically validated.

Originality/value

This study demonstrates the need to develop educational interventions that increase blog authors' and video hosts' awareness of risks associated with raw flour and that translate this knowledge into practiced behaviors.

Abstract

Purpose

Wheat is considered nutritionally poor, due to deficiency of essential amino acids such as lysine and threonine, whereas fenugreek (Trigonella faenum graecum L.) flour has a high protein content (25 per cent), lysins (5.7g/16gN), soluble (20 per cent) and insoluble (28 per cent) dietary fibre besides being rich in calcium, iron and beta‐carotene. Fenugreek seeds contain 20 per cent soluble fibre (gum), which can act as functional agent in wheat dough. The presence of bitter saponins in fenugreek seeds limits their acceptability in foods. However, it has been possible to debitter fenugreek seeds by using various domestic processing methods. Therefore, their use can be exploited as functional and nutritional food as well as therapeutic agents. Hence, in the present study efforts have been made to develop wheat‐fenugreek‐based health bread.

Design/methodology/approach

In commonly grown varieties of wheat, namely WH‐423, and fenugreek namely Pusa, early bunching was obtained. Fenugreek seeds were divided into three portions. One portion was left unprocessed (raw), while the other two portions were soaked (12hr at 37C) and germinated (48hr at 37C) separately. Soaked and germinated samples were dried at 55‐60C. Dried samples of raw, soaked and germinated seeds were ground to fine powder. Fenugreek seed powder (raw, soaked and germinated) was blended separately with wheat flour at different levels, namely 5, 10, 15 and 20 per cent. Breads from control and supplemented flours were baked in replicates. Baking, organoleptic and nutritional characteristics were analysed in the control and supplemented breads. The data were statistically analyzed in complete randomized design for analysis of variance according to the standard method.

Findings

Supplementation of wheat flour with fenugreek flour from 5 to 20 per cent levels increased the protein, lysine, minerals and fibre contents of bread. Additions of fenugreek (raw, soaked and germinated) up to the level of 15 per cent produced bread with a satisfactory loaf volume and other sensory quality attributes (crumb colour, crumb texture, taste etc.), whereas the 20 per cent level of supplementation caused a depression effect in loaf volume and the breads were found to be bitter in taste, However, among the various supplemented breads, germinated fenugreek flour‐supplemented bread at 15 per cent level showed satisfactory baking and organoleptic characteristics and contained an appreciable amount of protein (24 per cent), total lysine (3.02g/100g protein), dietary fibre (12.04 per cent) and minerals.

Practical implications

Fast food are becoming as popular, as in developing countries. Keeping this fact in view, in the present study, health breads were prepared. The developed product had good acceptability, was nutritionally rich and had therapeutic value. So, these can be considered for commercialization.

Originality/value

As fenugreek seeds contain 20 per cent soluble fibre (gum), and 5.7g/16gN lysine contents, the soluble fibre of fenugreek seeds has been reported to reduce blood sugar and cholesterol levels. Therefore, their use can be exploited in the development of health foods.

Abstract

Purpose

The purpose of this paper is to assess the bioactive ingredients of whole flours of oat, maize and soyabean, utilise them for developing functional cookies and evaluate their physical and nutritional quality parameters.

Design/methodology/approach

Cookies were prepared from blends of whole flours of wheat, oats, maize and full fat soyabean. Whole wheat and oat flours were blend in different proportions (100:0, 80:20, 60:40, 40:60 and 20:80 and 0:100, wheat:oat, w/w) and supplemented with quality protein maize (QPM) and full fat soyabean flours, at 10 per cent (w/w) each, of the total blend. Cookies were studied for their physical attributes, proximate and nutritional compositions. A significant (p=0.05) increase in spread ratio, crude protein, crude fat and crude fibre contents of the cookies was observed with increase in the proportion of oat flour in the blend.

Findings

Cookies prepared from blend containing QPM and soyabean flours had higher antioxidant activity than control whole wheat cookies. An increase in extractable β-glucan content and in-vitro protein digestibility was also observed with the increase in the proportion of oat flour. The highest overall acceptability was observed for cookies prepared from blends having a wheat–oat proportion of 60:40. These cookies also had a 17.5 per cent higher genistein content as compared to their raw flour blend. Higher genistein levels were observed in the composite cookies.

Originality/value

The cookies prepared from composite whole flours rich in isoflavones and β-glucan reflect their potential as a new functional food for the prevention and management of diseases such as cancers, diabetes and cardiovascular disorders.

Abstract

Purpose

Soybean has great nutritional potential. Its high protein content makes it an alternative protein source to milk in situations where milk cannot be used due to allergic reactions or intolerance. However, the potential benefits of soybean might be limited by the presence of antinutritional factors, including trypsin inhibitor activity (TIA). The purpose of the study is to evaluate the effect of dehulling and germination on the nutritive value of the soy flour and on the factors that could negatively affect the nutritional potential of the bean.

Design/methodology/approach

Soybean seeds were soaked for 24 h and allowed to germinate for one to three days. Soaked soybeans were manually dehulled and the flours obtained were evaluated for nutritional and antinutritional factors.

Findings

Dehulling and germination produce significant increase in crude protein and crude fiber and ash content (p = 0.05). Crude fat and starch content decreased, but the reduction was insignificant. Trypsin inhibitor levels were significantly lower after germination and dehulling of the seeds (p = 0.05).

Originality/value

Dehulling and germination are cost-effective processing techniques to improve the nutritional quality of the legume.

Abstract

Imagine Sir Edmund Hillary and Tenzing Norkey arriving at the summit of Everest (29,029 ft) in 1953, only to discover that they were standing on several thousand feet of ice. Imagine the questions that would have followed. Had they climbed the wrong mountain? Could they still legitimately claim to be standing at the highest point on the Earth's surface? How should the heights of mountains be recorded for official purposes?

Abstract

Purpose

The purpose of this paper is to determine the antimicrobial compounds extracted from various types of soybean materials; raw soybean, soybean flour and roasted soybean. Bacteria growth inhibition was tested in E.coli and S. aureus by disk diffusion method. Efficiency of antimicrobial activities were compared among the extracted solution.

Design/methodology/approach

Soybean (Glycine max) isoflavones contain the ability to inhibit the growth of many strains of microorganisms. The solid-liquid extraction, ethanol-hexane extraction, was modified to isolate the inhibitory compounds from the three different types of soybean materials. All crude extracts at various concentrations performed under different extracted solutions (75, 50, 25, 12.5, 6.25 and 3.125 percent) were tested with E. coli. and S. aureus to determine the antimicrobial activities and the minimum inhibition concentration (MIC). Disk diffusion method was chosen to study the antimicrobial activity of isoflavones.

Findings

Soybean flour extract inhibited the growth of E. coli and S. aureus more effective than roasted soybean and raw soybean, respectively. The MIC of inhibitory compounds extracted from soybean flour was 6.25 percent (0.031 mg/ml), roasted soybean was 25 percent (0.125 mg/ml) and raw soybean was 50 percent (0.250 mg/ml). Crude extracts of soybean flour and roasted soybean showed better results than raw soybean. All the three of extracted soybeans inhibited the growth of E. coli better than S. aureus.

Originality/value

Ethanol-hexane extraction was successfully used to isolate the antimicrobial compounds from raw soybean, soybean flour and roasted soybean. Comparison of antimicrobial activity showed that soybean flour contained the highest inhibition activity.

Abstract

Although the host, the future body of Christ in the Catholic Eucharist, seems to lie completely outside of the economic system, it needs to be produced and sold. The majority of host producers are female monasteries for which the production process brings double tension: as an economic activity within a religious utopia (the monastery) and as the economization of something that is considered to be a religious good. This double tension provokes the question, how do the nuns legitimate this economic process in their monastery without desacralizing the symbolic good? Trying to answer this question, nuns typically deny the economic dimension of production and transaction, yet the sheer existence of this economy proves it is accepted. This chapter examines the relationship between economy and religion through an analysis of the ambivalence in the production and marketing process of altar bread.

Abstract

Purpose

The aim of the study is to compare the effect of steaming method and time on the physico‐chemical properties of underutilized Dioscorea dumetorum with three more commonly consumed Dioscorea rotundata, Dioscorea cayenensis and Dioscorea alata.

Design/methodology/approach

Raw and pre‐gelatinized flour were produced from the yam species. Pre‐gelatinization was done by steaming diced cubes in autoclave at 68,950 Nm‐2 for 5 min and in Barlett steamer at 98±2°C for 10, 20 and 30 min. Flour samples were analyzed for amylose content, swelling index, consistency, solubility, water absorption capacity, and iodine affinity for starch.

Findings

The physico‐chemical properties of the flours were affected by both species and steaming time. Pre‐gelatinization of the tuber reduced amylose content in all the yam species, which reduced further with increase in steaming time. Except for amylose content and iodine affinity for starch, D. dumetorum compared with D. rotundata and D. cayenensis in the parameters that were measured. Samples autoclaved for 5 min had value similar to those steamed in Barlett steamer for 10 and 20 min for all the parameters that were measured, except consistency.

Practical implications

It is very important to encourage the cultivation and utilization of D. dumetorum because of the high yield and nutritional composition to enhance the nutritional and financial well‐being of the populace.

Originality/value

Pre‐gelatinization is important as pre‐treatment for yam tubers. Underutilized D. dumetorum could be useful in ingredient formulation for product development, especially as a thickening agent.

Abstract

Purpose

The purpose of this paper is to evaluate the effect of dehulling/soaking on the chemical, functional and anti‐nutritional contents of three varieties of beans. This research work involved comparative study of the underutilized bean species with the commonly consumed beans in Nigeria.

Design/methodology/approach

Three species of legumes were used for this study. The cowpea seeds were divided into two parts. One part was milled and packaged for raw flour while the other part was dehulled and soaked for 30 min, dried in the oven, milled and packed. For the pigeon pea and African yam beans, the raw beans were milled and packaged while part of the seeds was steamed for 5 min and the coats were removed. The dehulled beans were soaked for 30 min, dried in the oven, milled and packaged. Chemical, functional and anti‐nutritional content were determined on the samples.

Findings

Fat content ranged from 0.95 to 1.98 per cent. Ash and crude fibre ranged from 1.98 to 6.13 and 2.41 to 7.90 per cent, respectively. Raw cowpea had the highest calcium content (3.86 per cent) while pigeon pea had higher value in magnesium content (2.01 per cent). Raw African yam beans had the highest iron content (23.44 per cent). Bulk density, swelling index and water‐absorption capacity ranged from 0.53 to 0.92 g/cm3, 2.3 to 5.9 and 0.9 to 2.8 ml H2O/g, respectively. African yam bean had higher values in oxalate, phytate and tannin contents while cowpea had higher saponin content. Raw flour of pigeon pea had higher value in trypsin inhibitor.

Originality/value

This work enables us to make use of the underutilized beans. These beans were higher in nutrients than the cowpea used. Processing of these beans will make them useful for human nutrition without imposing any health problem to the consumer. They could also be converted to flour and used in formulating food such as weaning food.

Abstract

Purpose

This study aimed at the addition of grape residue flours in beef meatballs to evaluate their behavior on physic-chemical and sensory properties. Furthermore, it is intended to discuss the importance of the substitution of synthetic additives with natural ones, the enhancement of consumers' diets and the prevention of inappropriate waste disposal.

Design/methodology/approach

The grapes' residues were collected from wine production and transformed into flour. Their proximal chemical composition and antioxidant activities were analyzed. Then, meatballs were formulated with 0 (control), 3.5 and 7% grape flours. Lipid oxidation analyzes were performed on raw and thermally processed meatballs. Triangle and ranking sensory tests were performed to assess the consumer's perception of product appearance and flavor and the consumer's preference, respectively.

Findings

Bordeaux and Trebbiano grape flours were rich in dietary fibers, composed of 44.2 and 55.6% fibers, respectively. They showed a high antioxidant activity, in which Trebbiano was high than Bordeaux. The addition of grape flours reduced the lipid oxidation of meatballs by close to 50% than the control sample. Differences in the appearance and flavor of some meatballs were identified by the panelists; however, the flavor's change did not displease them.

Originality/value

The grape residue is rich in phenolic compounds, natural dyes and dietary fibers. Its addition as a functional ingredient in meatballs reduces the addition of synthetic additives, adds fiber to the consumer's diet and prevents inappropriate waste disposal.
