title: Optimization of bread quality with quinoa flour of different particle size and degree of wheat flour replacement

description: Abstract The study aimed to assess the influence of quinoa flour of different particle size and degree of wheat flour replacement on dough and bread characteristics. Dynamic rheology and farinographs were used to describe the dough parameters. Specific volume, texture, porosity, color, overall quality and chemical assessment were performed as well. It could be observed that the degree of wheat flour substitution by quinoa flour significantly influenced the G’ and G” values in linear and quadratic terms (p ≤ 0.01 and p ≤ 0.05). Particle size played a significant role in increasing G’ and G” only in quadratic terms. Increasing quinoa substitution of wheat flour and interaction of PS and QS significantly increased the porosity of breadcrumbs. Moisture content was mainly affected by the particle size of quinoa flour and increased the values of this parameter. The optimization revealed that the most suitable combination would be the composition of bread with 219 μm and 5.41% of substitution.

title: Isolation and functional caharacterization of chia (Salvia hispanica) proteins

description: Abstract The objective was to isolate and characterize the proteins of chia seeds cultivated in the Mexican southeast. The main protein fraction was glutelins (42.94%) that had the highest Water Absorption Capacity (WAbC). Prolamins had the highest Water Adsorption Capacity (WAdC) (1.83 g/g). Glutelins registered the highest Water Holding Capacity (WHC). A higher Oil Holding Capacity (OHC) of chia protein fractions was registered in globulins and a higher Organic Molecule Absorption Capacity (OMAbC) was registered in albumin fractions (5.5 g/g of sample). At pH 2, 4 and 6, the glutelins registered a higher Emulsifying Capacity (EC) while, at pH 8 and 10, the prolamins recorded a higher EC percentage. Chia fractions registered the highest Foam Capacity (FC) values at pH 8 for globulins and pH 2 for albumins, prolamins and glutelins. Foaming and emulsifying stability (FS and ES) was greatly influenced by pH.

title: Changes in sugar contents and invertase activity during low temperature storage of various chipping potato cultivars

description: Abstract Storage of tubers is vital for uninterrupted supply to potato chips/fries industry. Cold storage is preferred to maintain tuber quality. However, prolonged storage at low temperature results in cold induced sweetening (CIS) leading to sugar accumulation and browning of chips. Slowing down the CIS is of economic importance for potato industry. Screening of potatoes after cold storage for low sugar and invertase activity with exploration of best frying color was the aim of current study. Reducing sugars (RS), invertase activity and chips color were estimated after subjecting the tubers at 3°C and 7°C storage. Analytical techniques were adopted for quantification of RS and invertase activity while nine-point Hedonic scale was used for chips color evaluation. Highest invertase activity with maximum RS (mg 100-1g) and dark brown chips were observed in Kuroda following the Santé (247.83), Asterix (216.73), Crozo (193.42), Hermes (171.57) and Lady Rosetta (134.07) after storage at 3°C. Low RS were found in tubers stored at 7°C with good frying color in Lady Rosetta (98.23) followed by Hermes (104.31) and Crozo (113.27). Conclusively storage temperatures have significant effect on quality of tubers in which 7°C proved best with less RS and invertase activity having good frying color.

title: Gluten-free pasta: development of a new formulation based on rice and lupine bean flour (Lupinus Mutabilis) using a mixture-process design

description: Abstract Gluten-free pasta was developed by substituting rice flour (RF) with lupin flour (LF). The factors tested were the substitution of RF by LF (10g/100g -30g/100g), egg (8g/100g -30g/100g) and guar gum (0.15g/100g -1g/100g) using a mixture-process design. Seven response variables were measured. Luminosity, ash content, protein content, chrome, hue, weight gain and loss of solids were explained by mixture-process models (p&lt;0.05). LF was a significant factor due to its high protein and mineral content. A sensory analysis was performed to quantify consumer acceptance. The best formulation was obtained with 20g/100g LF, 30g/100g egg and 0.15g/100g guar gum. A proximate analysis was performed in order to compare it with a control sample (100% rice flour, 30% whole egg, 0.15% guar gum). This formulation showed an increase in ash (37.5 g/100g) and protein (63.15 g/100g), fat (112.12 g/100g) and fiber (126.66 g/100g). This study showed that partial substitution of RF by LF could be a reliable alternative for gluten-free products.

title: Physicochemical and microbiological stability of fermented dairy beverages added with red rice extract

description: Abstract Fermented dairy beverages added with red rice extract and whey were the developed, physicochemical and microbiological properties were evaluated. A central composite rotatable design was applied, using nine treatments with three replicates. The pH indicated that the beverages could be consumed without the addition of preservative for up to 28 days of storage. The beverages are characterized as partially skimmed, with high protein content, zinc, manganese and copper levels, similar potassium and iron levels and low sodium, magnesium and calcium levels, if compared to the recommended daily index. The absence of pathogens and numbers of viable lactic acid bacteria above the established minimum level were observed. The physicochemical parameters were evaluated by ANOVA and PCA, grouping the beverages into four groups according to their physicochemical properties and three groups according to mineral levels. It is suggested that the most adequate treatments contain between 20 and 34% of red rice extract and from 26 to 54% of whey because of their lower copper contents.

title: Sensory attributes and Lipid oxidation of smoked lamb sausage formulated with passion fruit meal, potassium chloride and calcium chloride

description: Abstract This study evaluated the sensory attributes and lipid peroxidation of smoked lamb sausage prepared with passion fruit meal, potassium chloride and calcium chloride. The samples were produced and smoked at Instituto Federal do Espírito Santo, where they were kept vacuum packed and frozen until laboratory analysis. The formulations with passion fruit meal presented lower weight loss by smoking. No microbiological growth was detected in the 90-day study period. Formulation 1 was the best in the attributes color, aroma, flavor, texture, overall impression and purchase intention. The use of passion fruit meal to replace fat, potassium chloride and calcium chloride did not affect oxidation of the product during the study period. The addition of passion fruit meal, potassium chloride and calcium chloride to smoked lamb sausage, especially in Formulation 1, produced the best results and the levels of these ingredients did not interfere in oxidation.

title: Consumer behavior of organic and functional foods in Brazil

description: Abstract The objective of this study was to correlate the gender and behavior of consumers of organic foods enriched with functional properties. The study was carried out by investigating the profile of organic and functional food consumers through the application of a questionnaire. A total of 1230 responses (of the questionnaire) were collected from people from all Brazilian states through social networks and e-mails following the snowball technique during the months of February and March 2017. The results showed that women expressed greater interest in consuming organic foods enriched with functional properties compared to men. Men and women agree that organic food are produced in a sustainable. Their high price, difficult access, irregular supply and availability in few establishments were highlighted as the main limiting factors for not consuming organic food, while an increased motivation (of consumption) was related to the awareness that organic foods are healthier and can improve quality of life. Fruits and vegetables are the most consumed organic foods among men and women, however women consume more functional foods than men. Thus, there are few differences in behavior and eating habits of organic foods between men and women.

title: Collagen production from chicken keel bone using acid and enzymatic treatment at a temperature of 30 °C

description: Abstract The aim of this study was to investigate the effect of acid pretreatment, temperature and enzyme concentration on the acid-enzymatic extraction of soluble collagen from chicken keel bone cartilage. A chemical composition analysis and protein profile characterization of this slaughter by-product were also conducted. The cartilages were extracted with 0.5 mol/L of acetic, lactic and citric acids for 24, 48 and 72 hours. Subsequently, optimization with a 22 factorial design was performed with three replications at the central point for a total of 7 experiments; the analyzed response was the collagen content of the obtained isolates. The cartilage under study has a high protein content (90.27% dry basis) consisting of approximately 35.7% collagen and is a source of essential and predominantly hydrophobic amino acids. Pretreatment with acetic acid for 24 hours led to greater extraction potential and consequently, a better collagen yield (30.12%). The electrophoretic profile of the obtained collagens revealed the existence of an α1 chain, indicating that this collagen was type II. Statistical analysis demonstrated that the acid-enzymatic procedure favored a temperature of 30 °C.

title: Alternative source of probiotics for lactose intolerance and vegan individuals: sugary kefir

description: Abstract In this review, we aimed to explain general information about sugary kefir, microbial diversity, production process and potential health effects. Although sugary kefir has been known for many years, it has not been studied much. Studies have shown that sugary kefir has a similar microbial diversity compared to traditional milk kefir and therefore may be an alternative source of probiotics. However, sugary kefir has been shown to contain probiotic properties such as adhesion to the mucosa by reaching the lumen of the mucosa, colonization of the pathogens to the mucosa. In this way, potential health effects such as antimicrobial activity, suppression of inflammation agents, reduction of oxidative stress, immunomodulation, anticancer, and anti-obesity have been demonstrated by clinical studies. However, studies on whether or not these effects are present on humans are very limited. Therefore, randomized double blind placebo controlled studies are needed to investigate potential health effects on humans.
