Abstract

Purpose

The purpose of this paper is to develop a cereal bar supplemented with coffee beverage that has health benefits.

Design/methodology/approach

Six types of cereal bars containing raisins or prunes with different concentrations of coffee were developed. Acceptability tests and physicochemical characterizations were performed by analysis of moisture, ash, protein, lipids, fibres and carbohydrates. Moreover, the levels of phenolic compounds, the fatty acid profile and the in vitro antioxidant activity were evaluated by the DPPH free radical scavenging and iron-chelating activity methods. The bars were assessed using the check-all-that-apply (CATA) methodology. The phenolic compound and antioxidant activity data were evaluated by analysis of variance. Averages were compared by the Scott–Knott test. To verify the characteristics of the food bar per the attributes cited in CATA, main component analysis was performed using the SensoMaker software.

Findings

The concentration of coffee did not affect the centesimal composition values. The highest percentage of scavenging activity of free radicals was observed in the food bar containing raisins, with a maximum concentration of coffee beverage equivalent to 10 mL. These values were higher in cereal bars containing raisins than in bars containing prunes with the same concentrations of coffee. The acceptance sensory test showed good acceptability ratios, ranging from 74.33 to 85.22 among different food bar formulations.

Practical implications

The bar consisting raisins and 100 per cent coffee presented high values of protection against oxidative stress, phenolic content and satisfying acceptability, thereby making it a novel possible alternative as a differentiated product with possible health-beneficial effects.

Social implications

This paper provides a differentiated product, through healthy ingredients, with convenience of purchase, besides having added value and possible health beneficial effects.

Originality/value

The bar consisting of raisins and 100 per cent coffee presented high values of phenolic content and protection against oxidative stress, as well as satisfying acceptability, thereby making it a novel possible alternative as a differentiated product with possible health-beneficial effects.

Abstract

Purpose

Flours obtained from pulps and peels of unripe banana were evaluated regarding their chemical composition and glycemic responses in rats. Moreover, this study aims to propose a new assay to measure glycemic responses using animals.

Design/methodology/approach

Proximal composition, total dietary fiber and its insoluble and soluble fractions, mineral content and tannins were evaluated. Glycemic responses were measured using albino Wistar rats (seven animals/group).

Findings

Flours from pulp and peel of unripe banana presented high content of carbohydrates and minerals. Moreover, flour from peel was rich in insoluble fiber, whereas flour from pulp had adequate proportion of insoluble and soluble fractions. Consumption of banana flours from peel and pulp did not affect fasting blood glucose of normoglycemic rats. Flour from pulp, when consumed in concentrations of 10 and 15 per cent of the diet, significantly stimulated lower glycemic responses in the animals.

Originality/value

Results presented in this study disclose unripe banana flour as an interesting food source, which may be indicated for preventing some types of diseases, such as diabetes, obesity and dyslipidemia. Moreover, the glycemic index assay using animals promoted accurate answers, as the diets were standardized, unlike studies with humans, which do not control variations related to omission and distortion of information regarding food intake.

Abstract

Purpose

The purpose of this research is to develop and characterize a sugar-free Brazilian mixed fruit jam, containing marolo, sweet passion fruit and soursop, enriched with polydextrose and fructooligosaccharides (FOS), and evaluate in vivo the effect of consumption of this product.

Design/methodology/approach

In total, 48 male rats were divided into six groups and fed a AIN-93M rodent diet supplemented with 10% jam enriched with different proportions of FOS and polydextrose. The effects on glycemic response, mineral utilization and fecal and histological characteristics were evaluated.

Findings

The addition of the jams enriched with the fibers in different levels based on current legislation, in the diet of the rats, for 30 days, did not affect significantly (p = 0.05) parameters such as daily mean consumption (DMC) and daily weight gain (DWG), fecal weight, mineral absorption, glycemic responses and glycemic index of the diets and histological parameters. Moisture and ether extract contents of the stool, however, were positively affect by these ingredients. These parameters were significantly higher (p < 0.05) in groups treated with FOS and polydextrose.

Originality/value

The sugar-free Brazilian mixed fruit jam besides to increase availability and add value to exotic Brazilian fruits could be an alimentary source of interest. However, more specific studies, aimed at questioning and confirming the optimal doses of prebiotics to normal and dysglycemic individuals and with longer duration, are needed.

Abstract

Purpose

As studies investigating the effects of fructan sources, such as yacon, on glucose and lipid metabolism showed different results, additional research is required to establish a clear relationship between them. Thus, this paper aims to evaluate possible effects of the consumption of the yacon pulp flour (YPF) on biological and metabolic parameters such as food consumption, weight gain, serum glucose levels and fecal lipid excretion of rats, as well as determine the role of glycemic index (GI) of the diets added of this ingredient on those parameters.

Design/methodology/approach

For this purpose, 24 male albino Wistar rats were divided into four groups, which received the following treatments for 17 days: Group 1 (G1) (Control) – American Institute of Nutrition (AIN)-M; Group 2 (G2) – AIN-M added 5 per cent YPF; Group 3 (G3) – AIN-M added 10 per cent YPF and Group 4 (G4) – AIN-M added 15 per cent YPF. Analysis of fasting and postprandial glycemia was conducted for elaboration of the glycemic curve and calculation of the GI of the diets. Lipids loss was measured by quantification of crude fat in feces after consumption of the diet.

Findings

YPF, regarding the concentration in the diets, did not elevate the fasting glucose among the groups. The postprandial glucose of the animals declined in different postprandial glucose peaks of the groups ingesting YPF in relation to the control one, especially in group treated with 15 per cent YPF, between 30 and 60 min (p <0,05), confirming the influence of the dietary fiber on the absorption of the glucose. The ingestion of YPF increased dragging of lipids to the animal feces, proportional to the amounts of YPF added to the diets. According to the regression analysis, followed by regression testing to 5 per cent, there was a significant difference between the experimental groups, being that the elevation of the percentage of YPF added to the diet caused a proportional increase in the lipid levels in the animal feces.

Originality/value

YPF could be an alimentary source of interest, mainly when the focus is on disease risk prevention such as diabetes, obesity and dyslipidemias.

Abstract

Purpose

The purpose of this paper is to analyse the packaged food market in Brazil by examining the use of nutrition and health claims and marketing techniques, as well as the different levels of industrial food processing in relation to product category, nutrition information and price.

Design/methodology/approach

A survey was conducted on the labels of pre-packed foods and non-alcoholic beverages marketed in a home-shopping website in Brazil.

Findings

The authors showed that the use of nutrition and health claims on packaged foods in Brazil is widespread and varied across different food categories. Marketing techniques were also prevalent, and techniques emphasising general health, well-being or naturalness were the most frequent type used. Overall, products carrying nutrition and health claims and/or using marketing techniques had lower content of fat and higher content of fibre. However, the high prevalence of these strategies in ultra-processed foods is alarming. The presence of health claims and use of marketing techniques was not found to be an effective modifier of the three price measures. However, processed and ultra-processed foods were more expensive than unprocessed foods when considering price per energy and price per 100 g or mL.

Originality/value

These results indicate that there are clear opportunities to improve the packaged food environment in supermarkets. It is important to highlight the need to develop public policies to address these issues, including restriction of the promotion and advertising of unhealthy foods and beverages and use of warning labels.
