Effects of dense phase carbon dioxide pasteurization on the physical and quality attributes of a red grapefruit juice
No full textABSTRACT: Red grapefruit juice was treated with continuous dense phase carbon dioxide (DPCD) equipment to
inactivate yeasts and molds and total aerobic microorganisms. A central composite design was used with pressure
(13.8, 24.1, and 34.5 MPa) and residence time (5, 7, and 9 min) as variables at constant temperature (40 ◦C), and
CO2 level (5.7%) after experimentallymeasuring CO2 solubility in the juice. Five log reduction for yeasts and molds
and total aerobicmicroorganisms occurred at 34.5 MPa and 7 min of treatment. A storage study was performed on
the fresh juice DPCD treated at these conditions. ◦Brix, pH, titratable acidity (TA), pectinesterase (PE) inactivation,
cloud, color, hue tint and color density, total phenolics, antioxidant capacity, and ascorbic acid weremeasured after
the treatment and during 6 wk storage at 4 ◦C. During storage, the DPCD-treated juice showed no growth of total
aerobic microorganisms and yeasts and molds. Cloud increased (91%) while percent PE inactivation was partial
(69.17%). No significant (α = 0.05) differences were detected between treated and untreated samples for ◦Brix, pH,
and TA. Treated juice had higher lightness and redness and lower yellowness. No significant differences (α = 0.05)
were detected for the hue tint values while the color density value was higher for the treated samples compared to
the untreated. The treatment and the storage did not affect the total phenolic content of the juice. Slight differences
were detected for the ascorbic acid content and the antioxidant capacity. The experimental results showed evidence
that the treatment canmaintain the physical and quality attributes of the juice, extending its shelf life and safety
UTILIZATION OF PUMPKIN AND APPLE IN BREAD-MAKING
No full textDesenvolveu-se cinco formulações de pães de abóbora, cinco de pães de maçã e uma formulação padrão. Para elaboração das amostras, foi utilizada 200 gramas de mistura com 10%, 20%, 30% e 50% de purê de maçã e abóbora e demais ingredientes necessários para a panificação. Os produtos foram avaliados comparando-os ao padrão através de características como: cor interna e externa, forma e simetria, cozimento, granulação, aroma, sabor e características da crosta. Os resultados mostraram que, para o processo de mistura com o purê de maçã pode-se utilizar até 50% do purê sobre a farinha de trigo na formulação de pães com resultados satisfatórios, enquanto que para o processo de mistura com purê de abóbora obteve-se boa aceitação a concentração máxima de 30%. Os pães com maçã apresentaram resultados melhores que os de abóbora em relação as características de sabor e aroma.Five formulations of pumpkin's and apple's bread and one standard formu1ation were developed. For e1aboration of the samples were utilizated mixture with 10, 20, 30 and 50% of pumpkin's and apple's puree and other ingredients for breadmaking. The products were evaluated comparing with standard by the following characteristics: extern an internal color, form and symetry, crust's characteristics, cooking, granulation and flavour. The mixture of apple or pumpkin puree substituting part of wheat flour during breadmaking reached good results. Using 50% of apple puree and maximum of 30% for pumpkin puree was found good acceptability. Comparing the flavour characteristics of breads made with pumpkin puree and apple puree we concluded that the best results were reached with apple puree
Can we rely on delaying the uptake of sugar consumption in the prevention of early childhood caries?
No full text\ua9 The Author(s) 2025.A Commentary on: Feldens C A, de Barros Coelho E M R, V\uedtolo M R, Rogrigues P H, Kramer P F, Peres K G Effectiveness of a sugar consumption prevention programme in the first year of life on the occurrence of early childhood caries: a multicentric randomized trial in Brazil. Caries Res 2024; https://doi.org/10.1159/000541028. Study design: A multi-centre randomised controlled trial was carried out in Brazil. The intervention group received nutritional counselling based on dietary guidelines produced by UNICEF. The control group received standard dietary and maternal counselling provided by the hospital provider. Randomisation of participants was completed through a computer-based system with an investigator blinded to the recruitment process. Patients were followed up monthly using a combination of phone calls and home visits. Sample: Pregnant women were recruited from four hospitals, across three state capitals, participating in the Baby Friendly Hospital Initiative. Mothers were to be at least 18 years of age, testing negative for HIV/HTLV1, and had an uncomplicated pregnancy. Their newborns had to have a gestational age of more than 37 weeks and weigh more than 2.5 kg. A newborn with increased hospital stays due to infection or neonatal conditions which affected breastfeeding were not included. Sample size calculation was undertaken. Data analysis: Baseline data was collected. At 6- and 12-month intervals, a combination of validated questionnaires, including 24-hour recalls, and interviews were used to assess the diet. Oral health assessments were carried out by a blinded, trained and calibrated paediatric dentist. The primary outcome was a reduction in ECC. Effect measures (relative risk [RR]) were calculated to determine the effect of the intervention on not consuming sugar at 6 months and on the mean number of sugary items consumed at 12 months. Results: Baseline demographic data were similar, with no significant differences noted, between the intervention and control groups. The probability of not consuming sugar in the first 6-months was 2.4 times less in the intervention group relative to the control group (p = 0.016). ECC was diagnosed in 17.4% of the whole sample; however, no significant difference was noted between groups at any time point (p = 0.281). Conclusions: Increased intervention to the mother in the first 6-months of life was effective at reducing the amount of sugar intake. However, this did not lead to a statistically significant reduction in ECC
The Rise and Decline of Catching Up Development. An Experience of Russia and Latin America with Implications for Asian 'Tigers'
No full textThis book deals with the general problems of catching up development, which have been considered through lenses of the concrete cases studies of the former Soviet Union and post-Soviet Russia, Latin American and East Asian countries. The book is subdivided into two parts. In the first part, some general problems of development in the past century are considered and draw attention to the cases of Russia and Latin American countries. The second part is devoted to the NICs of E/SEA.Development, neo-liberal Reforms, globalization, crisis
