UV light has been used as a germicidal agent in water treatment and surfaces disinfection because of its capacity to affect DNA microorganisms.On the other hand, low doses UV-C irradiation can trigger some favourable reactions biological organs, such fruits vegetables, which lead various beneficial effects, improvement their shelf-life or increase content health promoting components.The objective this work is review results recent works on application post harvested vegetables taking into...
The chemical parameters pH, soluble solids, caffeine, trigonelline, total chlorogenic acids, caffeoylquinic 3-O-caffeoylquinic acid, 4-O-caffeoylquinic 5-O-caffeoylquinic dicaffeoylquinic 3,4-O-dicaffeoylquinic 3,5-O-dicaffeoylquinic 4,5-O-dicaffeoylquinic feruloylquinic 3-O-feruloylquinic and 5-O-feruloylquinic acid were measured in Arabica (C. arabica) Robusta canephora) green coffees order to determine discrimination parameters. In general, coffee showed higher values for but the content...
The drying process is an essential thermal for preserving vegetables and can be used in developing dried products as healthy alternative snacks. effects of air-drying conditions using a convection dryer with hot air at different temperatures (60°, 65°, 70°, 75°, 80 °C, the range 5-200 min, fixed speed 2.3 m/s) were tested on quality slices (2.0 ± 0.1 mm) sweet potato (Bellevue PBR). For each time temperature, condition, physicochemical parameters (moisture content, CIELab color, texture...

Roasted coffee samples of the two major trade species (Coffea arabica and C. canephora) were studied to identify sensory descriptors that might be used determine blends production evaluation, following expectations consumers. Coffee beans roasted at 220 + 10 °C, for 7, 9, 11 min, profiles beverages assessed. From descriptive analysis eigenvalues allowed identification principal components (PCs), being variance between 68.9% 21.1%. In first PC characteristic odor, astringency, body, bitter...
The increasing demand of organic agriculture (OA) is based on the consumer’s belief that agricultural products are healthier, tastier and more nutritious. effect OA conventional (CA) methods elemental compositions green red sweet peppers were studied. highest concentrations Ca, Cu, K P occur in from both states ripeness, with emphasis Ca contents. Furthermore, principal component analysis (PCA), points out to a clear separation, regarding concentrations, between CA. average fruit weight...
The baobab tree (Adansonia digitata L.) is found widely in the forests and savannas of sub-Saharan Africa. fruit has a sour slightly sweet taste consumed by natives, thus containing high nutritional value providing source income for rural people. This study aimed to compare composition pulp from different localities Namibe province (Angola). Twenty samples were collected markets four municipalities Namibe. results obtained showed that there some geographic location dependence on functional...
Edible insect powder, particularly from the cricket Acheta domesticus L., is a promising sustainable alternative to traditional livestock-derived protein. Insects provide high protein content, fibre, and essential minerals, making them suitable for food applications. This study investigates viability of diets rearing A. domesticus. Two experimental were tested: RI [50% horticultural by-products (HP) + 50% commercial diet (CD)] RII (33% HP 33% CD fish by-products). The results demonstrated...
As Doenças Crônicas Não Transmissíveis (DCNT), como a Doença Pulmonar Obstrutiva Crônica (DPOC), representam um problema de saúde pública global, sendo o tabagismo uma das principais causas evitáveis morte. Este estudo teve objetivo promover conscientização sobre os riscos do e uso cigarros eletrônicos entre jovens Pará, por meio intervenções educativas. A metodologia incluiu aplicação questionários, distribuição materiais informativos palestras em escolas públicas. Os resultados indicaram...
The effect of freezing on the properties a raw ewes'-milk semi-soft cheese (Serpa cheese) was studied using small amplitude oscillatory (SAOS) and texture measurements, colour chemical parameters. introduced at three different stages ripening process (28, 35 42 days), cheeses were maintained frozen for 12 months. Cheeses submitted to slow or fast method, storage temperatures: -10 -20°C (three replicates each set conditions). Chemical data showed that only proteolysis indicators exhibited...
Abstract Dark chocolate presents exclusive characteristics that make it a food product with worldwide consumption and also as an ingredient in several industries. Although is energy-dense food, rich bioactive compounds recent studies have demonstrated health benefits from moderate consumption. Therefore, the quantification of different types cocoa, geographical origins, great importance to recognize single origin dark nutritional point view. produced Amelonado variety presented higher values...
In recent years, cocoa and dark chocolate have attracted the interest of consumers not only for their sensory characteristics but also nutritional properties positive impact on health. The baobab is a fruit African origin with sour slightly sweet flavour, widely consumed by local communities due to its unique features. aim this work was evaluate concentration flour in development functional chocolate, including physical, chemical, evaluations. results presented correlation between...
Arabica and Robusta coffee beans were roasted at 220 ± 10°C for 7, 9 11 min to identify chemical descriptors in the beverages. The pH of beverages showed lowest value medium roasting level. In each degree browning, soluble solids content remained slightly higher drinks. contents caffeine did not vary, but trigonelline decreased with burning up intensity. Chlorogenic acids also increasing time. 5-O-caffeoylquinic acid prevailed beverages, isomers dicaffeoylquinic feruolilquínic Robusta. It...
Raw ewes' milk semi-soft cheeses (RESS-cheeses) are important products in Portugal and several European regions. Creamy texture is an essential attribute of these cheeses, which results from structural properties that not always well characterized. Here, the changes occurring during ripening period a traditional RESS-cheese, known as Serpa cheese, were analysed through small amplitude oscillatory shear (SAOS). Rheological data was complemented with other physical chemical parameters,...
