| ABSTRACT Grape juices have been valued due to their potential health benefits, which have demanded increased grape productivity and quality. Five grape cultivars grown in Brazil, Isabel Precoce, Carmem, Violeta, Concord and Bordo were evaluated in 2013 and 2014 seasons for bioactive components and also for juice processing quality traits. Production cycle was the longest for Carmem but lower and similar for Violeta, Isabel, Bordo and Concord. Isabel showed higher productivity (5.4 kg∙plant-1) but lowest soluble solids content (16.9 °Brix), anthocyanins (26.7 mg∙100 g-1) and total phenolics (110.7 mg∙100 g-1). The highest anthocyanins contents were observed in Violeta (189.9 mg∙100 g-1) and Bordo (133.8 mg∙100 g-1). These cultivars were also rich in... |

| The levels of ten bioactive amines and the physico-chemical characteristics of Cabernet Sauvignon, Cabernet Franc and Merlot wines from Bento Gonçalves, RS, Brazil, vintage of 1999 were investigated. The physico-chemical characteristics varied significantly: pH from 3.80 to 4.07, total acidity from 67.7 to 85.3 meq/L, alcohol content from 11.45 to 12.46 mL/100 mL and total SO2 from 9.6 to 102 mg/L. Six amines were detected in every sample - spermidine, putrescine, histamine, tyramine, serotonine and phenylethylamine. Total amine levels ranged from 2.03 to 7.60 mg/L. Putrescine was the prevalent amine, contributing with 20 to 66% of total levels. The amine profile and total levels were affected to a greater extent by vinification practices compared to grape... |

| Chemical analysis of turmeric (Curcuma longa L) cultivated in eight different cities in the state of Minas Gerais, Brazil was carried out. The levels of curcuminoid pigments varied from 1.4 to 6.14 g/100 g and of volatile oil from 0.97 to 7.55 mL/100 g (dry basis). Samples from Patrocínio, Arinos and Brasilândia contained higher pigment levels compared to the others. The sample from Patrocínio contained the highest volatile oil content. The mean levels of ethyl ether extract, protein, fiber, ash and starch were 8.51, 7.01, 7.22, 7.81 and 39.87 g/100 g dry basis, respectively. Laboratory extraction of flavour free oleoresin was performed in triplicate. A higher yield of pigment in the oleoresin was obtained when the volatile oil was extracted with water... |

| Este trabalho teve como objetivo avaliar a atividade antimicrobiana da cúrcuma em pó, da curcumina disponível no comércio, dos pigmentos curcuminóides purificados e dos óleos essenciais da cúrcuma. As amostras foram analisadas quanto aos teores de pigmentos curcuminóides por cromatografia líquida de alta eficiência. O óleo essencial foi também analisado quanto à densidade, índice de refração e perfil das substâncias voláteis por cromatografia gasosa e detector de ionização de chamas. A atividade antimicrobiana in vitro foi determinada pelo método de difusão em ágar com discos de papel estéreis, impregnados com os extratos, sendo os diâmetros dos halos de inibição medidos com paquímetro. Os extratos etanólicos da cúrcuma, da curcumina comercial, e dos... |

| The present study aimed to evaluate the chemical properties of green corn, grown in both organic and conventional farming systems, using a completely randomized factorial design. Four corn varieties (AG 1051, BR 106, SWB 551 and VIVI) of green corn kernels were evaluated for color, proximate composition, total calories, carotenoids and bioactive amines. The farming system affected some chemical and physical characteristics of green corn, but this effect was dependent upon variety. In general, organic green corn kernels were reddish (a* color component) and had higher levels of β-carotene compared to the conventional ones, suggesting that these characteristics are related. Moreover, organic green corn had higher levels of total carbohydrates and total... |

Amostras foram coletadas em Belo Horizonte, MG, no período de dezembro de 1999 a maio de 2001 - 18 marcas diferentes, cada uma constituída de cinco amostras de um mesmo lote. Os teores de umidade variaram de 10,16 a 28,40g/100g, sendo que 33% das amostras não atenderam à legislação. A atividade de água variou de 0,579 a 0,889. Os valores de pH variaram de 4,78 a 5,62. Os aditivos pesquisados, nitrato de sódio, nitrito de sódio e ácido sórbico variaram de 5,11 a 159,1mg/kg, de não detectado a 129,2mg/kg e de não detectado a 2401,8mg/kg, respectivamente.

| 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... |
