| Maintaining plants in the field for two consecutive crop cycles is one of the latest techniques used by strawberry growers to reduce production costs. The goal of this research was to evaluate the postharvest fruit quality of six strawberry cultivars produced for two consecutive seasons with the same plants. They were planted from May to July 2010 under low-tunnel and fruits were evaluated in two growing seasons (season 1= January, February, and March 2011 and season 2= August, September, and October 2011), totaling three harvests of each cultivar in each year season. Fruits were picked up randomly among 500 plants of each cultivar, organized into five replications of five fruits and kept for three days before analysis under refrigeration (average... |

| Ageratum conyzoides (mentrasto or goat weed) has invaluable socio-economic-cultural importante being used as unconventional vegetable in traditional cuisine of Minas Gerais state, Brazil. In folk medicine it is used as a purgative, febrifuge, antiemetic and against colic, ulcers and uterine problems. The objective of this study was to quantify the concentration of phenolic compounds, flavonoids and antioxidant activity in ethanol extracts of goat weed, as a step towards analytical and bioanalytical validation of its use as aherbal and/or medication as functional food. Thus, analysis of the levels of phenolic, flavonoids and antioxidant activity (AAT %) were made in ethanol extracts of leaves (EF), flowers (EFL) and roots (ER) of goat weed. Measuring... |

| O processo de produção de queijo cremoso a partir de leite de cabra descrito neste Comunicado Técnico foi desenvolvido com base na tecnologia do queijo ?Fromage Blanc?, de origem francesa, diferenciando-se pela utilização de uma cultura comercial de Streptococcus thermophilus como fermento iniciador, em cocultura com probiótico Lactobacillus rhamnosus. O queijo ?Fromage Blanc? é fabricado tradicionalmente com leite de vaca submetido a uma fermentação láctica simples e dessorado ligeiramente. Tem consistência cremosa e é consumido adicionado de sal, pimenta, cebola ou como sobremesa com geléias ou frutas |

| Abstract: The objective of this work was to quantify the total phenolic content (TPC) and total antioxidant activity (TAA) of fruit from Brazilian genotypes of feijoa (Acca sellowiana). Skin and flesh tissues of the fruit were evaluated for the Alcântara, Helena, Mattos, and Nonante cultivars, and for the 2316 accession. TPC and TAA were both assessed in aqueous and hydroalcoholic extracts, and TAA was assayed by the DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS [2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)] methods. The TPC values, for aqueous extracts of the skin and flesh tissues, were 114.9 and 88.3 mg gallic acid equivalent (GAE) per 100 g fresh weight (FW), respectively. The corresponding values for TAA determined by the DPPH method, the... |

| Abstract: The objective of this work was to evaluate the effect of the processing conditions of soybean tempeh on the contents of β-glycoside isoflavones and on their bioconversion into aglycones. Different times of soaking (6, 12, and 18 hours), cooking (15, 30, and 45 minutes), and fermentation (18, 24, and 30 hours) with Rhizopus oligosporus at 37°C were evaluated for tempeh preparation. Grains from the cultivar 'BRS 267' were used, and the experiment was carried out according to a central composite design (23). The response functions comprised the contents of genistin, malonyldaidzin, malonylgenistin, daidzein, and genistein, quantified by ultraperformance liquid chromatography (UPLC). Soaking, cooking, and fermentation times change the content,... |

| Abstract: The objective of this work was to evaluate the physicochemical attributes and vitamin C contents of fruits of five Brazilian genotypes of feijoa (Acca sellowiana), at harvest and after cold storage. The Alcântara, Mattos, Helena, and Nonante cultivars, as well as accession 2316, were studied. The assessed attributes were: fresh mass loss, titratable acidity, soluble solids contents, soluble solids contents/titratable acidity ratio, pH, skin and flesh color, texture, and vitamin C contents (skin and flesh). After storage, there were reductions of 2.9% in soluble solids contents, of 32.2% in titratable acidity, and of approximately 85% in texture attributes, besides increases of 36.3% in the soluble solids contents/titratable acidity ratio and of... |

| The objective of this work was to analyze changes in the isoflavone profile, determined by high performance liquid chromatography, at different processing stages and after refrigeration of tempeh. For tempeh production, clean soybean grains from cultivars BR 36 (low isoflavone content) and IAS 5 (high) were dehulled, and the separated cotyledons were hydrated and then cooked in boiling water for 30 min. Spores of the fungus Rhizopus microsporus var. oligosporus were inoculated in the cooked and cooled cotyledons, and incubated at 32ºC for 6, 12, 18, and 24 hours in perforated polypropylene bags, for fermentation. The resulting tempeh was stored at 4ºC for 6, 12, 18, and 24 hours. After 24-hour fermentation, isoflavone glucosides were 50% reduced, and the... |

| Abstract: The objective of this work was to evaluate the viability of probiotic bacteria in bioyogurt with the addition of honey from Africanized and Jataí bees, in different concentrations. To prepare the fermented milk, reconstituted powdered milk and lactic acid starter culture were used. The bioyogurt was evaluated at 0, 7, 14, 21, 28, and 35 days of storage. Analyzes of pH, titratable acidity, and selective count of the Lactobacillus acidophilus LA-5 and Bifidobacterium BB-12 microorganisms were carried out. Counting was done, respectively, on MRS agar, in aerobiosis, and MRS-LP agar, in anaerobiosis, with plates incubated at 37°C for 72 hours. Treatments were arranged in a completely randomized design in split plot, with five treatments: without... |

| The objective of this work was to evaluate the influence of the breed and of the addition of bioactive substances to forage on the color of smoked pork loin. Two pig breeds (Polish Landrace and the crossbreed Polish Landrace x Duroc), three types of bioactive components (organic selenium; 2% of canola oil and 1% of flaxseed oil; and 2% of flaxseed oil and 1% of canola oil), and a control treatment were evaluated. Computer image analysis included the color assessment of muscle, fat, connective tissues, and smoked loin surface. For Polish Landrace, selenium supplementation caused higher values of red, green, and blue color components of the muscle tissue, which were lower for the crossbreed. However, there was no difference in the color components of loin... |

| Abstract The aim of this work was to evaluate the effect of storage temperature, in passive modified atmosphere (MA) and atmospheric composition in active MA on quality maintenance, total phenolic compounds (TPC) and total antioxidant activity (TAA; DPPH and ABTS methods) of ‘Tupy’ blackberry. Two experiments were carried out. In experiment 1, the fruit were stored for eight days at 0, 5 and 10 °C in passive MA. In experiment 2, the initial atmospheres of 21.0 kPa O2 + 0.04 kPa CO2 (passive MA); 9.2 kPa O2 + 9.2 kPa CO2 (active MA with high CO2); 1.4 kPa O2 + 0.04 kPa CO2 (active MA with low O2); and 1.4 kPa O2 + 9.6 kPa CO2 (active MA with low O2 + high CO2) were evaluated for eight days at 0 °C. In both experiments, the fruit were packed in Xtend®... |

| ABSTRACT The present study evaluated the effect of cooking on the levels of bioactives compounds and antioxidant activity in grains cowpea cultivars. The analysis were performed on the raw samples and after cooking in pressure cooker. Regarding the bioactive compounds present, the grain cultivar BRS Aracê exhibited the highest levels of total phenolic compounds (mg/100 g) both before and after cooking, 205.10 ± 2.89 and 150.62 ± 2.64, respectively. Spermine and spermidine were identified in the cultivars (mg/kg) BRS Milênio in the amount of 120.5 in crude and 50.4 in cooked grain, in the BRS Tumucumaque in the amount of 116.2 in crude and 47.9 in cooked grain, exhibited significant losses of these compounds after cooking. It was not detected the presence... |
