AVALIAÇÃO DA PERCEPÇÃO DOS HÓSPEDES SOBRE MICROGREENS OFERECIDOS NAS REFEIÇÕES DO LAPINHA SPA, LAPA, PR, BRASIL: UM PROJETO DE EXTENSÃO PILOTO
Microgreens are seedlings produced from seeds of different species including vegetables, herbs or grains. Research has shown that these have a higher level of nutrients When compared to the same adult vegetable, and microgreens have gained prominence in haute cuisine to compose the ornamentation of dishes. The objective was to evaluate the acceptability of microgreens by guests of a SPA. This is an extension project that it was conducted at Lapinha Spa, PR, Brazil, aiming to contribute to the inclusion of this important source of nutrients in the guests' diet. The microgreens (lettuce, watercress, kale, amaranth, beet and sunflower) were produced in plastic trays and harvested after 15 days. The perception of microgreens was evaluated through questionnaires to evaluate the attributes: decorative value (DV), sophistication and innovation (SI) and palatability (PA). The RV attribute presented very good perception (90%), followed by SI (79%) and AP (60%). The percentage of responses whose perception level was considered very good and good was higher than 80% for all evaluated attributes. From these results, it can be concluded that microgreens have relevant characteristics and give a higher visual value to the dishes offered in this establishment.

Uso potencial de folhas de batata-doce para consumo humano
The objective of this work was to select sweet potato (Ipomoea batatas) genotypes with leaves with potential to be used for human consumption. Twenty-six experimental genotypes and four commercial cultivars were tested in a randomized complete block design with three replicates and ten plants per plot. The trial was carried out in the municipality of Lavras, in the state of Minas Gerais, Brazil. Leaf shape and lobe, aerial-part yield, edible-leaf yield, edible-leaf percentage, edible-leaf dry mass, and latex production, as well as leaf total chlorophyll, pH, soluble solids contents, titratable acidity, total phenolic compounds, and anthocyanin contents, were evaluated. Roots were characterized as to their pulp and peel colors. Fifteen genotypes presented the highest aerial-part (29.6 to 51.8 Mg ha-1) and edible‑leaf (7.8 to 12.7 Mg ha-1) yields. In the biochemical analysis, high contents of chlorophyll, total phenolics, and anthocyanins were observed. In addition, pH, soluble solids, and leaf titratable acidity did not differ significantly among the evaluated genotypes. Leaves of ten genotypes are recommended for human consumption.O objetivo deste trabalho foi selecionar genótipos de batata-doce (Ipomoea batatas) com folhas com potencial para serem usadas para consumo humano. Vinte e seis genótipos experimentais e quatro cultivares comerciais foram testados em delineamento de blocos ao acaso, com três repetições e dez plantas por parcela. O ensaio foi realizado no municÃpio de Lavras, no estado de Minas Gerais, Brasil. Foram avaliados formato e lóbulo da folha, produção da parte aérea, produção de folhas comestÃveis, percentagem de folha comestÃvel, massa seca de folha comestÃvel e produção de látex, bem como clorofila total, pH, conteúdo de sólidos solúveis, acidez titulável, compostos fenólicos totais e teor de antocianinas das folhas. As raÃzes foram caracterizadas quanto à s cores da sua polpa e casca. Quinze genótipos apresentaram as maiores produtividades de parte aérea (29,6 a 51,8 Mg ha-1) e de folhas comestÃveis (7,8 a 12,7 Mg ha-1). Nas análises bioquÃmicas, foram observados altos teores de clorofila, compostos fenólicos totais e antocianinas. Além disso, pH, sólidos solúveis e acidez titulável foliar não diferiram significativamente entre os genótipos avaliados. As folhas de dez genótipos são recomendadas para alimentação humana
Mesocarpo de coco babaçu (Orbignya sp.) como fonte de carbono para produção de meios de cultura para Trichoderma
Biological control has been studied as an alternative replacement of chemicals in agriculture . One of the microorganisms used in this system is the fungal species Trichoderma sp. In this work, media formulations were tested by replacing glucose babassu mesocarp (Orbignia sp.) Which has 69.46% starch in the composition. These culture media were used to cultivate three strains of the fungus Trichoderma . It was observed that the composition of the medium did not affect the growth of which statistically tested concentrations did not differ . For the time of 72h was no significant difference (p < 0.05) in diameter growth of strain 63 for the other however to the total time of the experiment the standard species proved stronger for longer, staying in log phase to the time 96 hours. The concentrations of immediate substituted carbon source (dextrose) at babassu mesocarp did not affect the growth of the fungus suggests that the mesocarp babassu is a good carbon source for the production of growth medium.O controle biológico vem sendo estudado como alternativa substitutiva de agentes quÃmicos na agricultura. Um dos microrganismos utilizados neste sistema é a espécie fúngica Trichoderma sp. Neste trabalho foram testadas formulações de meios substituindo-se glicose por mesocarpo de babaçu (Orbignia sp.), o qual possui 69,46% de amido em sua composição. Estes meios de cultura foram utilizados para cultivar três linhagens do fungo Trichoderma. Observou-se que a composição do meio não afetou o crescimento sendo que estatisticamente as concentrações testadas não diferiram entre si. Para o tempo de 72h houve diferença significativa (p <0,05) no diâmetro de crescimento da linhagem 63 para as demais entretanto para o tempo total do experimento a espécie padrão mostrou-se mais vigorosa por mais tempo, permanecendo na fase log até o tempo de 96h. As concentrações substituÃdas da fonte imediata de carbono (dextrose) pelo mesocarpo babaçu não interferiram no crescimento do fungo sugerindo que o mesocarpo de babaçu é uma boa fonte de carbono para produção de meio de crescimento
Manutenção da qualidade pós-colheita de pimenta de cheiro (Capsicum chinense) armazenadas sob atmosfera modificada e refrigeração
The goal of this study was to evaluate the effect of three different types of packaging on the life of de aromatic peppers (Capsicum chinense) stored under refrigeration for 10 days. The aromatic peppers were harvested, taken to the laboratory, selected, washed, sanitized and stored in different packaging in BOD (8 ± 1ºC, 90 ± 5% RH) for 10 days. The experimental design was completely randomized (CRD) in factorial scheme 3x6, with three different packaging (Styrofoam tray (15x15x3cm) coated with PVC, 14 micron, bag of polyethylene and polystyrene cup with 500ml) and 6 times storage (0, 2, 4, 6, 8 and 10 days). Analyses carried out every two days were: weight loss, firmness, color, identification of volatile compounds and evaluation of external appearance. Regardless of the package kept the peppers color and flavor. The package consists of a Styrofoam tray covered with cling film provides greater weight loss and strength and therefore less suitable for storage at 8°C de aromatic peppers.O objetivo deste trabalho foi avaliar o efeito de três diferentes tipos de embalagens sobre a vida útil de pimentas de cheiro (Capsicum chinense) armazenadas sob refrigeração, por 10 dias. As pimentas foram colhidas, levadas ao laboratório, selecionadas, lavadas, sanificadas e armazenadas nas diferentes embalagens em BOD (8 ±1ºC, 90 ±5% RH) por 10 dias. O delineamento experimental utilizado foi inteiramente casualizado (DIC), em esquema fatorial 3x6, sendo 3 embalagens diferentes (bandeja de isopor (15x15x3cm) recoberta com PVC, 14 micras, saquinho de polietileno e copinho de Poliestireno com 500ml de volume) e 6 tempos de armazenamento (0, 2, 4, 6, 8 e 10 dias). As análises realizadas a cada dois dias foram: perda de massa, firmeza, coloração, identificação dos compostos voláteis e avaliação da aparência externa. Independente da embalagem as pimentas mantiveram cor e aroma. A embalagem constituÃda por bandeja de isopor recoberta por filme PVC determina maior perda de massa e firmeza, sendo, portanto a menos indicada para o armazenamento a 8°C de pimentas de cheiro

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study
Summary
Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally.
Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies
have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of
the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income
countries globally, and identified factors associated with mortality.
Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to
hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis,
exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a
minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical
status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary
intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause,
in-hospital mortality for all conditions combined and each condition individually, stratified by country income status.
We did a complete case analysis.
Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital
diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal
malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome
countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male.
Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3).
Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income
countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups).
Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome
countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries;
p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients
combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11],
p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20
[1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention
(ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety
checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed
(ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of
parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65
[0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality.
Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome,
middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will
be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger
than 5 years by 2030
Physical-chemical and biochemical characterization of Buchenavia tomentosa Eichler fruits
Abstract The wild native species of the Brazilian savannah have attractive flavors and nutritive compounds. Among the Combretaceaes genus, the Buchenavia tomentosa Eichler plays an important role in popular medicine, however, little is known about its chemical composition. Thus, in order to a chemical-biological prospection in fruits of the Tocantins savannah, the aim of this work was to characterize the B. tomentosa fruits collected in the central and southern regions of Tocantins State, about some of its physical, physical-chemical and biochemical properties. The fruits, for this study, were collected in two regions (Palmas and Gurupi) in Tocantins State and analyzed in the parameters: coloration, centesimal composition, pectin, soluble solids, pH and acidity, vitamin C content and phenolic compounds. The study obtained results demonstrate that the fruits are of a light yellow color, are acidic, have high values of °Brix and glycidic fraction (carbohydrates). However, the high levels of vitamin C (1.26 to 3.57 g ascorbic acid per 100 g of pulp) and phenolic compounds (2.93 to 4.20 g GAE 100 g-1) are noteworthy. This study evidences a great nutritional potential for the fruits of B. tomentosa
Qualidade de mandioquinha-salsa minimamente processada e armazenada sob atmosfera modificada Quality of fresh-cut peruvian carrot: use of modified atmosphere
O objetivo deste trabalho foi verificar o efeito da atmosfera modificada, passiva e ativa, sobre a conservação de mandioquinha-salsa minimamente processada da cultivar 'Amarela de Senador Amaral', adquirida de lavoura comercial do MunicÃpio de Lavras, Minas Gerais (MG). As raÃzes foram selecionadas, lavadas com detergente neutro e enxaguadas em água corrente. Em seguida, foram imersas em solução de hipoclorito de sódio 300mg L-1, por 15 minutos, e secas em temperatura ambiente. As raÃzes foram descascadas e cortadas em fatias de aproximadamente 1cm de espessura, imersas em solução de hipoclorito de sódio 50mg L-1, por 10 minutos, drenadas em peneiras plásticas e embaladas. As bandejas contendo as fatias de mandioquinha-salsa foram armazenadas em câmara fria (5±1°C e 98% UR) por 15 dias. As seguintes análises foram realizadas a cada três dias: pH, acidez titulável, sólidos solúveis totais, firmeza, valores L* e b*, amido e avaliação sensorial (aparência e cor). O delineamento experimental foi inteiramente ao acaso (DIC), em esquema fatorial 3 x 6, sendo três tipos de atmosferas (passiva; ativa com injeção inicial das misturas: 2% O2 + 10% CO2 e 5% O2 + 5% CO2) e seis tempos de armazenamento (0, 3, 6, 9, 12 e 15 dias), com três repetições. Os valores médios de pH, acidez titulável, sólidos solúveis e firmeza encontrados neste trabalho foram 6,79, 0,13% de ácido málico, 4,04°Brix e 5,17N, respectivamente. A atmosfera modificada ativa (5% de O2 + 5% CO2) determinou maior valor L* à s mandioquinhas-salsa minimamente processadas no sexto e no décimo segundo dia de armazenamento, quando comparada com a atmosfera (2% de O2 e 10% CO2). A atmosfera modificada ativa com 5% O2 + 5% CO2 determinou maiores valor b* e teores de amido à s fatias de mandioquinha-salsa em comparação com as outras atmosferas. Conclui-se que a atmosfera modificada passiva, aliada à refrigeração e a boas práticas de fabricação, é suficiente para prolongar a vida útil de mandioquinhas-salsa minimamente processadas, preservando seus atributos de qualidade. Diante da avaliação sensorial realizada, a aparência e a cor das fatias de mandioquinha-salsa mantiveram-se aceitáveis para o consumo até o final do perÃodo de armazenamento.The aim of this research was to verify the effect of the passive and active modified atmosphere on the conservation of fresh-cut peruvian carrot, cv. Amarela de Senador Amaral, purchased from a commercial crop of Lavras, MG, Brazil. The roots were screened, washed with neutral detergent and rinsed in running water. Afterwards, they were immersed into a solution of 300mg L-1 sodium hypochlorite for 15 minutes and dried at room temperature. The roots were peeled and cut in slices of about 1cm of thickness and immersed into a solution of 50mg L-1 sodium hypochlorite for 10 minutes, drained in plastic sieves and packed. The trays containing the slices of Peruvian carrot were stored in a cold room (5±1°C and 98% RH) for 15 days. The following analyses were performed every 3 days: : pH, titrable acidity, total soluble solids, firmness, L* and b* values, starch and sensorial evaluation (appearance and color). The experimental design was completely randomized (CRD) in a 3 x 6 factorial scheme, with 3 sorts of atmospheres (passive; active with initial injection of the mixtures: 2% O2 + 10% CO2 e 5% O2 + 5% CO2) and 6 times of storage (0, 3, 6, 9, 12 and 15 days) with 3 replicates. The average values of pH, titrable acidity, soluble solids and firmness found in this work were 6.79, 0.13% of malic acid, 4.04°Brix and 5.17 N, respectively. The active modified atmosphere (5% de O2 + 5% CO2) determined higher L* value to the fresh cut Peruvian carrots at the sixth and twelfth day of storage as compared with the active (2% of O2 + 10% CO2). The active modified atmosphere with 5% O2 + 5% CO2 determined higher b* values and starch contents to the slices of Peruvian carrots as compared with the other atmospheres. It can be concluded that the passive modified atmosphere associated with refrigeration and good practices of manufacture is enough to extend the shelf life of fresh cut Peruvian carrots, keeping their quality attributes. In accord to the sensorial evaluation, both appearance and color of the slices of Peruvian carrots are kept acceptable for consumption until the end of the storage period
Vida útil de pêssegos 'Aurora 2' armazenados sob atmosfera modificada e refrigeração
O objetivo deste trabalho foi avaliar a eficiência da pelÃcula de fécula de mandioca 3% e de sacos plásticos de polietileno de baixa densidade na conservação da qualidade pós-colheita de pêssegos 'Aurora 2' armazenados sob refrigeração (9 + 1ºC e 90 + 5% UR) por 10 dias. O experimento foi realizado no DCA/Ufla, em Lavras-MG. A fécula 3% induziu maior perda de massa, comprometendo a qualidade final do fruto e tendo vida útil de apenas 6 dias. O uso do polietileno reduziu a perda de massa e manteve a firmeza, diminuindo a solubilização das pectinas
