title: Physicochemical, bioactive properties and antioxidant of Apis mellifera L. honey from western Paraná, Southern Brazil

description: Abstract The Southern region of Brazil is known for its floral diversity, presenting great potential for bee products such as honey, pollen, propolis and royal jelly. In this study, 67 honey samples provided by beekeepers from 14 municipalities of western Paraná were evaluated. Physicochemical parameters, bioactive compounds and antioxidant activity were analyzed. The physicochemical parameters of the samples were in compliance with the specifications by national and international standards, presenting average values of 3.26, 34.54 meq.kg-1, 18.75%, 10.79 mg.kg-1, 0.14% and 340.10 µS.cm-1, for pH, acidity, moisture, hydroxymethylfurfural, ash content and electrical conductivity, respectively. The nutritive values of honey, on average, achieved 0.28% of protein from 69.09% of total sugars, 64.57% of reducing sugars and 4.28% of sucrose. Bioactive compounds showed average values of 34.83 mg GAE/100 g-1 of total phenols and 16.26 mg EQ/100 g-1 of flavonoids, enabling antioxidant activity of 2.68 µmol FE (II)/g-1 of FRAP, 1.01 µmol ET/g-1 from ABTS and 0.12 µmol ET/g-1 of DPPH. This first study evaluated the parameters through cluster analysis and observed nine groups formed, as well as the characteristics between the samples with similar reaction. We concluded that the honey samples have high similarity and confirmed the quality of the honey produced.

title: Probiotic characterization of a commercial starter culture used in the fermentation of sausages

description: Abstract Probiotic starter culture does not only improve the safety and shelf-life of products but also extends health benefits to the consumer. This study investigated the probiotic potential of a commercial starter culture used in the fermentation of meat sausages. The starter culture tested, composed of Lactobacillus sakei, Staphylococcus xylosus, and Staphylococcus carnosus, was evaluated for resistance to antimicrobials, low pH values and bile salts; production of gas and capsules; acidification capacity; and growth after exposure to different pH values, temperatures, and curing salts. The antagonistic capacity was also assessed against Escherichia coli ATCC25922, Salmonella Enteritidis ATCC13076, Vibrio parahaemolyticus, Staphylococcus aureus ATCC43300, Enterococcus faecalis ATCC29212, and Listeria monocytogenes CERELA. The starter culture was susceptible to all tested antimicrobials and strongly inhibited pathogenic strains, with inhibition halos diameters &gt; 30 mm. The culture was resistant to all concentrations of bile salts tested, did not produce gas or capsules, and could grow within a temperature range of 15 °C to 35 °C in saline medium containing healing salts (nitrite/nitrate). Although, the inability of the culture to withstand low pH, indicating intolerance to stomach acidity, limits its use as a live probiotic, beneficial health effects may be derived from the inactivated culture.

title: Food safety knowledge, attitudes and practices of street food vendors in Jashore region, Bangladesh

description: Abstract Most people now have their meals outside their homes and are vulnerable to illness caused by food. Unsafe food preparation and supply by vendors have made food safety a concern for public health. Jashore is a densely populated city, this study was designed to evaluate food safety knowledge, attitude and practice (KAP) of food vendors in Jashore region, Bangladesh. A randomized descriptive cross-sectional study on food safety KAP was conducted among 200 food vendors. Where 96% were male food vendors, 72.5% were smokers, and 63% were found to be overweight or obese. While 72.5% vendors had good knowledge of food safety, only 33% and 0.5% had good food safety attitude and practice, respectively. Among the socio-demographic factors investigated, only the level of education showed significant influence (p = 0.005 and 0.015) on the food safety knowledge and practice of the vendors. While handling food, over 90% vendors did not use any personal protective equipment, 4.5% had diarrhoea, 8.5% did not wash their hands after going to the toilet and 28.5% reused previous leftover oils. The data suggest that the overall food safety knowledge of suppliers in the Jashore region is good but their attitudes and practices need to be improved.

title: Traditional sour cassava starch obtained with alterations in the solar drying stage

description: Abstract After natural fermentation and solar drying, sour cassava starch acquires expansion property. Traditionally, solar drying occurs without protection, and consequently physical contamination can arise. Thus, the aim of this study was to produce sour cassava starch using a low-cost solar dryer to prevent contamination, whilst retaining the expansion property. The samples were characterized in relation to chemical composition, microscopy and physical contaminants, as well as expansion, thermal, pasting, structural and technological properties. In addition, biscuits were prepared and compared with commercial samples. The solar dryer provided faster drying and lower moisture levels than the control. The specific volumes of the sun-dried products were similar to the control, with minimized contamination. The granules of the starches showed slight erosion on their surface, which was probably due to amylolytic enzymes. X-ray diffraction showed a typical A-type pattern. DSC analysis resulted in higher gelatinization temperatures and enthalpy changes for the sour cassava starch. The pasting properties showed a reduction in the viscosity peak at neutral pH. Although the cassava starch biscuits made with sour cassava starch dried in the solar dryer presented lower expansion levels in relation to the other biscuits produced with commercial sour cassava starch, they had desirable sensory characteristics.

title: Fatty acid composition, cardiovascular functionality, thermogravimetric-differential, calorimetric and spectroscopic behavior of pequi oil (Caryocar villosum (Alb.) Pers.)

description: Abstract The objective of this investigation was to determine the composition and fatty acids profile of pequi (Caryocar villosum (Alb.) Pers.) oil, as well as its functionality in cardiovascular health, thermogravimetric-differential, calorimetric and spectroscopic behavior. The methodology used followed the standards established by the American Oil Chemists Society (AOCS). The results show oil with high nutritional value with predominance of unsaturated fatty acids (70%), especially oleic acid (52.67%) and linoleic acid (15.20%). The oil functionality indexes were expressed as cardiovascular protectors with low atherogenic and thrombogenic indexes (0.38 and 0.75) with a high hypocholesterolemic ratio (2.58). The oil pattern in the spectral bands 2980 to 2870cm-1 confirmed the predominance of unsaturated fatty acids with prominent peaks corresponding to double bonded chemical groups bands. The oil behavior under progressive temperature rises in an air atmosphere, supports the potential applications of this fruit by-product, that exhibits high thermal and oxidative stability with reduced mass loss at temperatures (267 °C and 376 °C) above those habitually used in food and industrial uses. These data show that unconventional fruits can increase and diversify the number of ingredients that can be used in food preparations and in the food, pharmaceutical, dermocosmetic, biofuel and other industries.

title: The effects of different beehives on propolis production and quality

description: Abstract The present study was conducted to investigate the effects of wood, styrofoam and plastic beehives on propolis production and phenolic content. In this study, propolis was obtained in three different periods as follows: before, during and after honey production. The yield and quality of the collected raw propolis samples were analyzed. Total phenolic (TP) content, total tannin (TT) content, total antioxidant capacity (FRAP) and phenolic composition were determined as propolis quality parameters. The highest propolis production was determined in wood beehives, followed by styrofoam and plastic beehives in this study. The analysis of temporal propolis production demonstrated that 9.29 ± 11.37 g was produced in post-season, 2.88 ± 4.48 g was produced in the season, and 1.23 ± 0.80 g was produced in pre-season. Duncan and LSD multiple comparison tests, which were conducted to compare the hive groups and the collection periods, demonstrated that the differences were statistically significant (p &lt; 0.05). Furthermore, the highest TP and FRAP values were found in plastic beehives, suggesting that the propolis phenolic content and antioxidant capacity varied based on the hive type and collection period.

title: Physicochemical, sensory properties and in-vitro bioaccessibility of phenolics and antioxidant capacity of traditional noodles enriched with carob (Ceratonia siliqua L.) flour

description: Abstract In this study, the use of carob flour (CF) was investigated to improve the nutritional, antioxidative, and sensory properties of the noodles produced by the traditional method. In traditional noodle production, carob flour was used as a substitute to wheat flour at six different ratios (0% -control: Cmilk, Cwater, 10-40%, CF; w/w). In the noodle samples, L* and b* decreased whereas a* value increased as the CF substitution ratio increased. Regarding the CF substitution, which was found to be a natural antioxidant source rich in phenolic compounds added to the noodle formulation, the antioxidant capacity, total phenol content, and their bioaccessibility values increased. Bioaccessibility of total phenolic content (%) values (22.43-30.07%) of CF-added noodle samples were significantly higher than those of the control samples (p &lt; 0.05). According to the bioaccessibility results of antioxidant capacities, FRAP (50.17%) showed the highest value in the 40% CF noodle sample. As a result, the use of 10% and 20% carob flour in the noodle formulation were determined as the optimum values in terms of sensory properties. In developing new food formulations with high functional properties, it has been recommended to use carob flour as a functional food ingredient.
