title: Potential antioxidant retention and quality maintenance in raspberries and strawberries treated with calcium chloride and stored under refrigeration

description: Abstract Raspberry and strawberry fruits were stored at 0 °C and relative humidity (RH) of 95% for eight days. The fruits were treated with calcium chloride and their quality parameters and weight loss monitored and compared with those of untreated ones. A higher weight loss was observed for the untreated raspberries (16%) than for the fruits treated with 2% calcium chloride (5.3%). Similarly, untreated strawberry fruits lost more weight (8.5%) than those treated with 2% calcium chloride – only 4.1%. The application of calcium chloride did not significantly influence the total acid content of the fruits. After 8 days storage the total soluble solids (TSS) had decreased to 10.22 ± 0.06, 9.60 ± 0.05 and 9.65 ± 0.12 in the raspberry fruits treated with 0%, 1% and 2% calcium chloride, respectively, and to 7.00 ± 0.17, 6.57 ± 0.08 and 6.35 ± 0.04 in the strawberry fruits treated with 0%, 1% and 2% calcium chloride, respectively. After storage, the ascorbic acid contents were significantly (p ≤ 0.05) higher in samples of raspberry and strawberry fruits subjected to 2% calcium chloride dips. The CaCl2 treatments had a significant effect on retaining the ascorbic acid contents in these fruits. The treatment of raspberry and strawberry fruits with calcium chloride had a positive effect (p&lt; 0.05) on the retention of the total phenolic contents (TPC) during the storage period. 66% and 74% of the antioxidant potentials were retained in the untreated samples of raspberries and strawberries, as against 78% and 89% in the 2% calcium chloride treated samples of these fruits.

title: Cronobacter spp.: infections, occurrence and food regulations ‒ a review in Brazil

description: Abstract Cronobacter is an opportunistic bacterium associated with infections in newborns due to the consumption of powdered infant formulae. It is now known that Cronobacter can cause infections in individuals of any age with a higher prevalence in the elderly, urinary infections being the most common syndrome in this group. The identification of powdered infant formulae as the contamination vehicle in cases of meningitis caused by Cronobacter in neonates led the regulatory agencies to establish specific measures to control such pathogens in these products. Thus a literature review was carried out concerning the epidemiology of Cronobacter infections, the occurrence of the pathogen and food regulations in Brazil. It was found that cases of the infection were reported in Brazil from 1997-2013, with a higher occurrence in neonates. The precise number of cases could not be determined, and in some reports, identification of the microorganism was questionable. In most of the cases reported the contamination vehicle was not investigated or could not be determined. There have been reports of contamination by Cronobacter in samples of powdered infant formulae commercialized in Brazil, but their occurrence seems to have reduced after the adoption of stricter sanitary measures by the regulatory agencies. Cronobacter has also been isolated from spices and herbs, flours, cheese and from cereal mixes destined for children; and from these samples, four species were identified: C. sakazakii, C. malonaticus, C. dublinensis and C. muytjensii. The presence of the pathogen in different types of food is worrying because it may represent a risk if consumed by individuals belonging to one of the risk groups (neonates and elderly). It is important to encourage research about the epidemiology of the genus Cronobacter in order to identify the classes of food that can act as contamination vehicles and the real prevalence of infections in Brazil.

title: Neosartorya glabra polygalacturonase produced from fruit peels as inducers has the potential for application in passion fruit and apple juices

description: Summary Polygalacturonases are enzymes with the biotechnological potential for use in fruit juice clarification and for the enhancement of filtration efficiency. The aim of this work was to assess the production of polygalacturonase by the fungus Neosartorya glabra by means of solid-state and submerged fermentation using fruit peel residues as the carbon source, and also apply the enzyme in the clarification and decrease in viscosity of passion fruit and apple juices. The highest polygalacturonase (4.52 U/g/h) production was obtained by means of submerged fermentation in Vogel´s medium (1964) containing orange peel – Bahia variety (Citrus sinensis), at a concentration of 1.5% (w/v, dried mass) at 30-35°C for 72 h. The polygalacturonase of the crude extract presented optimal activity at 60°C and pH 5.5. The enzyme retained around 90% of the initial activity after 180 minutes at 40°C, and 50% of the initial activity after 150 minutes at 50°C. The enzyme was shown to be stable at acid pH values (3.0-6.5) after 120 minutes at 25oC. All these favourable enzymatic properties make the polygalacturonase attractive for potential uses in the industry of pectin-rich fruit juices, since the application of the crude extract to passion fruit (Passiflora edulis) juice caused an 80% reduction in viscosity and 75% decrease in light absorbance. In the processing of apple pulp juice (Malus domestica), there was a 50% reduction in viscosity and 78% decrease in light absorbance.

title: Extraction and quantification of carotenoids from dehydrated mini-tomatoes (Sweet Grape) by applying different solvents

description: Abstract Nowadays, due to events such as urbanization, globalization and industrialization there has been an increase in illnesses connected to eating. It is believed that, in part, the consumption of fruits and vegetables helps prevent many of these diseases. Tomatoes contain high contents of carotenoids, which are red-orange pigments present in some vegetables. In the case of tomatoes, the carotenoids mostly found are lycopene and beta-carotene. Lycopene is found in greater amounts and acts as an important antioxidant, whereas beta-carotene is found in lesser amounts in the fruit and presents pro-vitamin A activity. Due to these and various other functions carried out by the carotenoids, they have been determined for a long time in various foods. They are easily extracted with organic solvents but show instability when in the presence of agents such as light, oxygen and heat. Thus this study aimed to analyze the extraction and quantification processes of carotenoids from dehydrated mini-tomatoes of the variety Sweet Grape by means of the solvent combinations: acetone/petroleum ether, acetone/chloroform and acetone/hexane, in order to verify which solvent was the best for this procedure. The carotenoids were quantified using a spectrophotometer by reading at 350-600 nm, referring to the absorption peaks of beta-carotene and lycopene. The results showed that the solvent with the best performance for extraction of the carotenoids from the product in question was the combination of acetone and hexane, followed by acetone/petroleum ether and finally acetone/chloroform, the latter also presenting a more difficult operational extraction procedure. With the acetone/hexane combination average contents of 25.71 and 26.53 mg 100 g-1 beta-carotene and lycopene, respectively, were extracted, showing a statistically significant difference at the 5% level from the extractions using the other solvents.

title: A systematic review to identify possible applications and barriers to the adoption of mass customization in food production

description: Abstract In a 4.0 industry scenario related to process integration, it becomes necessary to discuss the production of mass customized products for consumers. The companies have difficulties in implementing the strategy of mass customization (MC), especially in food processing companies, which can be explained by the lack of studies on factors that affect the success of the adoption of this strategy. As from a systematic literature review, this article aims to carry out a bibliometric analysis with the objective of investigating the possibilities of applying MC for mass customized food products, and identify barriers related to the implementation of MC. The results showed food perishability, processing difficulties, quantification of the nutritional values of the customized product and the complexity of the perception by the clients of the value added by customization as barriers to its implementation in the food sector. The results presented contribute to the identification of opportunities for new products and to the gathering of information that allows for guidance in the implementation of MC in the food sector.

title: Mineral and bromatological assessment and determination of the antioxidant capacity and bioactive compounds in native Amazon fruits

description: Abstract The proximate compositions, mineral contents, antioxidant capacity and bioactive compounds of 7 native Amazon fruits were chemically evaluated. The majority of the fruits showed high moisture contents (&gt; 63.02%), and ash, total crude protein and total carbohydrate contents in the ranges of 0.22–2.07%, 0.17–2.44% and 7.17–41.71%, respectively. High levels of total lipids were found in uxi (23.25%) and monguba (18.67%). A wide range of mineral contents was detected and the highest levels were found in the samples of monguba seeds (Ca, Cu, Mg, and Zn), uxi pulp (Fe, and Mn) and pajurá pulp (Na). All the fruits showed antioxidant capacity, but the pajurá revealed the highest potential, statistically similar to that of acerola (p &lt; 0.05). The highest vitamin C contents were found in bacuri and cupuaçu and the highest phenolic compound contents in monguba and pajurá fruits, but flavonoids were only detected in pajurá. A statistical correlation between the Na content and antioxidant capacity was also observed. Based on the results obtained, the fruits analyzed are suitable for use in the human diet, in the food and cosmetics industries as well as in pharmaceutical compositions.

title: Low-cost system to determine CO2 permeation through plastic films

description: Abstract The objective of this work was to develop a simple, low-cost and efficient method to evaluate the permeability of plastic food packaging films. Thus permeation chambers were projected and built, which allowed for the exchange of gases through a plastic film with a known area, in order to measure the specific CO2 permeability of each film. Low density polyethylene (LDPE) and polyvinyl chloride (PVC) films were evaluated. The results showed good correlation with the tests carried out using commercial permeability analysis equipments, in agreement with the values found in the specific literature. The method was shown to be efficient in the analysis of polymeric films, and could be used as a tool for determining the permeability of films to different gases, such as O2, CO2 and ethylene. Moreover, the equipment is easy to use and the parameters, such as relative humidity, temperature and flow, can be easily adjusted.

title: Blueberry and honey vinegar: successive batch production, antioxidant potential and antimicrobial ability

description: Abstract Gourmet vinegars are versatile culinary ingredients that have aroused the interest of consumers not only for their unusual taste, but also for their health benefits. In this work, blueberry and honey wine was first obtained using a bench-scale bioreactor. This wine had high concentrations of phenolic compounds (706.18 mg GAE/mL) and appreciable free radical scavenging ability against DPPH (161.42 µmol trolox equivalent/100 mL) and ABTS•+ (356.41 µmol trolox equivalent/100 mL), as well as ferric-ion reducing antioxidant capacity (1419.86 µmol FeSO4/100 mL). In sequence, vinegar was produced from the wine in wooden barrels using successive acetification cycles. The average acetic acid concentration found in the vinegars was 4.4 g/100 mL, and the average acetic acid yield and volumetric productivity were 52.69% and 0.38 g/(L.h), respectively. Appreciable polyphenolic compounds (681.87 to 847.98 µg GAE/mL) and anthocyanin (12.8 to 15.39 mg/L) contents were found and high antioxidant activity. In addition, the vinegars demonstrated antimicrobial ability against Bacillus subtilis and Salmonella enterica Typhimurium.

title: Allergen labelling: an assessment of the labels of chocolates considering the new Brazilian legislation

description: Abstract Food allergy is an adverse health reaction, whose clinical manifestations may lead to death. Of the various foods that may be a source of allergens, one can highlight chocolate. Depending on its composition, chocolate can accumulate a large number of allergenic ingredients, enhancing the risks associated with its consumption. The objective of this work was to evaluate the labelling of chocolates considering the Brazilian legislation RDC n° 26/2015. The chocolates were separated into eight categories, with 139 labels being evaluated. The declaration of containing allergens was not found on 11% of the labels, even though they contained ingredients with mandatory declaration. The categories “soy chocolate” and “confectionery” represented 40% and 33%, respectively, of the undeclared labels. At least one non-conformity with RDC n° 26/2015 was found in 53% of the chocolate labels, where the categories “diet/ light /zero chocolate” and “confectionery” presented non-conformity in 100% and 50% of the labels respectively. The declaration placed in an “obscure place, difficult to visualize and/or on the seal”, was the most recurrent non-conformity (21% of the labels). The legislation should be adequate to promote alignment in communication between the industry and the consumer. However, it was verified that adherence to the labelling rules for allergens is still not complete, even though the adjustment period already finished.

title: Quality parameters of tomatoes submitted to different doses of gamma radiation

description: Abstract Ionizing radiation can be used for different purposes in the food industry. In this study, the effect of irradiation doses (0, 0.5, 1.0 and 1.5 kGy) on the quality parameters of long life tomatoes (Lycopersicon esculentum Mill.), was evaluated during 4 storage periods (1, 7, 14 and 21 days). The different treatments were evaluated by analysing for colour, pH, total soluble solids (TSS), total titratable acidity (TTA), ratio (TSS/TTA), hardness, total lycopene and ascorbic acid contents, weight loss and maturation stage (O2 /CO2 ratio) for all the storage periods. The tomato samples were irradiated in a Co60 irradiator and maintained at 22 °C ± 1 °C. The quality of the tomato fruits was influenced by the gamma radiation basically by making the fruits softer and not degrading the ascorbic acid and lycopene contents at the doses evaluated. The irradiation process used in the doses evaluated was promising with respect to maintaining the quality parameters of long life tomatoes.
