title: Optimization on process of ripe canistel (Pouteria campechiana) fruit flour based on several quality characteristics

description: Abstract Canistel is a high carotenoid fruit which can be converted into gluten-free flour. The objective of the research was to determine the selected soaking and drying processes in ripe canistel fruit flour based on its sensory, phytochemical, as well as physical and chemical characteristics. The research methods consisted of determining sensory and phytochemical characteristics by soaking ripe canistel fruit in NaCl and citric acid solutions as well as determining the physical and chemical characteristics of the flour by various drying temperatures and duration. The results showed that NaCl solution was better to eliminate the bitter taste and maintain the orange color of canistel fruit flour. Furthermore, drying temperature affected moisture, carbohydrate, fiber, starch, and energy contents. However, it did not affect bulk density, protein, fat, ash, sugar, and beta-carotene contents. These data also confirmed that soaking in NaCl solution of 7.5% for 30 minutes followed by drying at 40 °C for 6 hours produced best canistel fruit flour.

title: Effect of vacuum pressure on Yamú fish (Brycon amazonicus) meat during cold storage

description: Abstract This study aimed to assess the cryoprotectant effect of vacuum packaging (35 and 45 kPa) on cold preserved (0 °C and -18 °C) fillets of Yamú (Brycon amazonicus), during 5 days of storage. We analyzed the physicochemical and microbiological changes in the fillets during storage time. Yamú’s water holding capacity, nitrogenated bases content (TVB-N) and texture (N) were affected (p ≤ 0.05) by time and temperature. Bacterial colonies in fillets did not represent a risk for human health after five days of storage. In conclusion, vacuum packing positively (p ≤ 0.05) reduces the effect of cold over Yamú fillets properties.

title: Selection of raw cow’s milk thermophilic lactic acid bacteria obtained from southwest Parana, Brazil, with potential use as autochthonous starter

description: Abstract This work aimed to isolate and identify Streptococcus and Lactobacillus species from raw cow’s milk obtained from Southwest Paraná - Brazil. We used randomly amplified polymorphic DNA (RAPD)-PCR to identify and type 58Streptococcus and 48 Lactobacillus isolates, of which 04 Streptococcus thermophilus and 02 Streptpcoccus macedonicus were confirmed by species-specific PCR and by sequencing of the 16S ribosomal RNA of 02Streptococcus lutetiensis/infantarius, 10 Lactobacillus fermentum, 03 Lactobacillus delbrueickii subspecies bulgaricus, 01 Lactobacillus rhamnosus/casei and 02 Lactobacillus helveticus. The results indicated predominance of Streptococcus thermophillus and Lactobacillus fermentum. Streptococcus thermophilus and Lactobacillus delbrueickii subspecies bulgaricus strains were tested on the basis of their acidification kinetics. Considerable variation between the Streptococcus thermophilus was observed for the maximum rate of acidification (Vm), with a maximum of -4.5 and minimum of -4.2 pH milliunits min-1. The Lactobacillus delbrueickii subspecies bulgaricus showed values between -8.4 and -7.1 pH milliunits min-1. These results suggest that strains characterized as having a high acidifying capacity, could be used as starters in cheesemaking. The ferments presented an excellent performance in the acidification process, generating adequate curves, characteristics of a starter culture.

title: Sensory quality and consumers’ acceptance towards wild and farmed brown-trout (Salmo trutta) and farmed rainbow-trout (Oncorhynchus mykiss)

description: Abstract The present study aims to compare the sensory qualities and the degree of acceptance of wild/farmed brown-trout (Salmo trutta) and the farmed rainbow-trout (Onchorynchus mykiss) by a consumer panel. Acceptability regarding attributes appearance, taste, texture, and global appreciation were evaluated on 20 wild brown-trout, 20 farmed brown-trout and 20 farmed rainbow trout by a consumers’ panel formed by 74 elements. Although the panel of consumers equally well accepted all samples, the rainbow trout had classifications slightly higher in all sensory attributes. This tendency was confirmed by internal preference maps performed for each studied attribute. Consumers’ slightly higher preference for farmed fish might indicate that farmed trout could be an alternative to wild brown trout.

title: Drying of jambolão (Syzygium cumini) pulp in spouted bed dryer: effect of egg white as drying carrier agent on product quality

description: Abstract This work evaluates the drying and properties of jambolão pulp powder produced with egg white-maltodextrin 10DE mixture as drying carrier agents, at variable proportions (corresponding to 19.5% of the formulation mass). The product was dried in a spouted bed dryer (air temperature of 70 °C, air flow of 2.9 kg/min and feed flow rate of 11 g/min) using low density polyethylene as inert particles. We assessed the influence of the egg white-maltodextrin mixture composition in the drying recovery and in the powder properties, such as moisture, water activity, particle size, bulk density, wettability, solubility, hygroscopicity, color and anthocyanins retention. Powders produced with higher egg white concentration showed higher anthocyanins retention (79%) and lower wetting time (6 min) than the ones with higher maltodextrin concentration. Conversely, the former presented reduction of 31% on mean diameter and increase of 35% in hygroscopicity of powders and lower dried product recovery (27%). Bulk densities increased 14% to 19% after storage during 40 days. The use of binary egg white-maltodextrin mixture as carrier agent in drying of jambolão pulp is feasible and showed good results for retention of anthocyanins and protein enrichment in the product.

title: Sweet potato peel flour in hamburger: effect on physicochemical, technological and sensorial characteristics

description: Abstract The aim of this research was to evaluate the influence of sweet potato peel flour (SPPF) on the physicochemical, technological and sensorial characteristics of bovine hamburger. Four hamburger formulations were prepared added SPPF: F1 (0%), F2 (0.75%), F3 (1.5%) and F4 (2.25%). The flour was characterized by high levels of minerals, carbohydrate and dietary fiber, which improved the nutritional profile of the hamburger. There was an increase in moisture retention and shrinkage, as well as a reduction in fat retention and cooking yield, as the level of SPPF addition increased. The addition of flour in the product significantly reduced (p &lt; 0.05) the values of L*, a* and b*. Similar acceptability to the standard sample was checked for the hamburger with the addition of up to 1.5% SPPF. However, all formulations had an acceptability index greater than 70%. It is concluded that SPPF is a potential ingredient to be added in bovine hamburger, improving nutritional and technological parameters and with low influence on the sensorial characteristics.

title: Thermostability of the visual color and anthocyanins from Rio-Grande-Cherry (Eugenia involucrata DC)

description: Abstract The extract of Rio-Grande-Cherry (Eugenia involucrata DC), pure and with stevia addition (0.75% and 1.5%) and sucrose addition (20% and 40%), was subjected to heat treatment at 10 °C, 25 °C and between 50 °C and 90 °C. Anthocyanins and the color parameters C* and TCD (total color difference) followed first-order reaction kinetics while h° followed a zero order kinetic model, under all conditions. The addition of sweeteners, through the reduction of water activity, influenced the thermal stability of the anthocyanins and of the color parameters C*, h° and TCD was the most pronounced effect in the latter. The lower the temperatures, the most relevant was the effect of the sweeteners on increasing half-life. Thermodynamically, the degradation reaction of anthocyanins was defined as endothermic, as well as non-spontaneous and transition state of the molecules more structurally organized than the reactants.

title: Kefir fermentation as a bioprocess to improve lentils antioxidant properties: is it worthwhile?

description: Abstract Kefir, a consortium of acetic and lactic bacteria and yeasts, is versatile for biotransformation of vegetable substrates and may improve their bioactive properties. Lentil is a legume rich in vitamins, minerals, complex carbohydrates and proteins, making it an excellent substrate for fermentation and obtaining bioactive molecules. We report the effect of different process variables on antioxidant properties of lentil extracts obtained using kefir as a biotransformation agent and experimental design. The results showed that the factors agitation (rpm) and incubation temperature exerted significant effects. Incubation temperature of 28 °C and agitation of 75 rpm were the most suitable conditions for kefir fermentation and maximizing the antioxidant properties of the fermented lentils. The highest antioxidant activities for fermented products were 4128.39, 35.87 and 23.20 μmol of Trolox equivalents per gram of sample (μmoL TE g-1) measured by Total Antioxidant Capacity, FRAP and DPPH-radical scavenging methods, respectively. Additionally, we detected that the initial fermentation times (in the first six hours) were enough to positively affect the antioxidant properties of the lentil extracts, reaching a percentage increase of up to 270% in the antioxidant activity of the fermented products in relation to those non-fermented samples.

title: Page optimization of the foam-mat drying process to soluble coffee production

description: Abstract The expansion of the soluble coffee production is an alternative to the traditional coffee consumption, which is necessary to meet the new demands of consumers looking for convenience and practicality. Thus, this study of techniques that simplify and reduce costs to obtain soluble coffee become even more pertinent. Therefore, the objective of this work was to optimize the drying process of coffee extract in the foam bed by adjusting the Page Model by non-linear regression. Two methods for the concentration of the extract were evaluated: (A) in rotary evaporator and (B) in open stainless-steel container. The kinetics of drying the coffee extract in a foam bed under the temperatures of 40, 50, 60, 70 and 80 °C were described by the model. Besides that, a multivariate equation was proposed for drying by detecting influence of temperature on the k parameter, of the Page Model and later validation of the results. The time to obtain the concentrated extract was close to the two concentration methods (A- 2 hours and 30 minutes and B- 2 hours and 40 minutes). The Page model presented a good fit with values of determination coefficients above 99%. The results confirmed that the temperature is a determinant factor in the product moisture loss speed, presenting shorter drying times with the temperature increase. The correlation between experimental and predicted data was satisfactory for the validation of the results. The mathematical model can also assist in the correlation of drying parameters with physicochemical and sensory changes of soluble coffee in order to improve technological parameters.
