Different architectures at a nanometric scale such as nanocrystals, nanofibers, nanomicelles, nanoparticles, and nanovesicles can be produced from native starches using "top-down" and "bottom-up" approaches. These starch nanomaterials (SNMts) have particle size lower than 1000 nm, exhibiting different physicochemical properties than those found in native starches. In recent years several studies have explored the applications of SNMts in the food sector. The production and food application of SNMts have grown mainly in the last 5 years due to the fact that SNMts can be used to stabilize biological and synthetic compounds with antimicrobial activity and antioxidant properties. Furthermore, SNMts can be used as a stabilizing agent in food emulsions, or as reinforcing material in food packaging. The current review article focuses on comprehensively analyzing the current state of the art in SNMts for food applications, aiming to encourage other research groups to expand production and application in the food sector.

Coffee packaging colour is a factor used to attract consumer attention and generate sensory and hedonic expectations. This study aimed to understand the effect of colour packaging on consumer expectations. A cross-sectional study with 432 volunteers was carried out using coffee packaging with black, red, green and yellow colours.Each coffee packaging was compared with another similar coffee packaging having the opposite colour in the chromatic circle (white, light blue, pink and dark blue colours). Results from volunteers using free word association show that important attributes related to coffee could be induced in the volunteers using food packaging with black, red and green colours. Furthermore, the white colour can also be used in coffee packaging; however, this colour was not correlated with warm products as expected in coffee. Finally, coffee packaging having pink, light and dark blue, as well as yellow colours was rejected by the volunteers, suggesting that those colours should be avoided in packaged coffee.

Food packaging is a factor used to attract consumer attention and generate sensory and hedonic expectations. Most food packaging use conventional labels having the nutritional table as the main component; however, other alternatives such as the traffic light (TL) and warning labels have been proposed to the food industry as an alternative to improve the consumer interpretation related to food products. This study aimed to understand the effect of two front-of-pack labels (TL and warning models) on consumer perceptions and purchasing intention using free word association. A cross-sectional study with 551 volunteers was carried out using chocolate bars and soft drinks having conventional labels and front-of-pack labels. Results from volunteers using free word association show that front-of-pack labels did not impact the

A pesca no Brasil é bastante diversificada, abrangendo comunidades pesqueiras artesanais distribuídas ao longo da costa, além de frotas industriais. Das sete espécies de tartarugas marinhas que ocorrem ao redor do mundo, cinco são encontradas no Brasil e todas interagem com a pesca. Esforços de pesquisa e conservação visando mitigar a captura incidental (bycatch) das tartarugas vem sendo realizados, sendo considerada uma linha de ação prioritária para a pesquisa, manejo e conservação. Com o objetivo de compreender de que maneira a pesquisa vem lidando com a questão da interação das tartarugas marinhas com a pesca no Brasil, no presente trabalho realizamos uma revisão da literatura visando identificar os avanços e as lacunas do conhecimento sobre a temática no país. Foi identificada uma literatura crescente desde os anos de 1960, com um aumento mais expressivo a partir dos anos 2000. Apesar do aumento das pesquisas, observamos um predomínio da literatura sobre a interação com a pesca industrial, em especial o espinhel pelágico, em detrimento de pescarias artesanais, a qual ainda carece de estudos, principalmente nas regiões norte e nordeste. Ainda, se faz necessário um melhor dimensionamento da mortalidade ocasionada pela captura na pesca e seu impacto nas populações, assim como na ampliação das estratégias de conservação.
