Article
The administration of bioactive compounds presents challenges due to the numerous physiological barriers in the gastrointestinal tract. To deal with one of these challenges, chitosan/carboxymethylcellulose micropolyelectrolyte complexes (micro-PECs) were developed to carry niacinamide, a model hydrophilic bioactive agent. A Box-Behnken design was u...
Chapter
Antioxidant packaging is an emerging technology that limits deteriorative reactions in oxidation-sensitive food products. The direct interaction of the antioxidant material with the packaged product may inhibit oxidation reactions by scavenging free radicals, consequently improving the food stability and extending its shelf-life. Although these pac...

The present invention relates to the development of vehicles for vitamin B3 (niacinamide) using chitosan and carboxymethylcellulose as carrier materials. It also refers to the process for obtaining vitamin B3 (microcomplexes) micro-PECs and their use in food matrices such as dairy drinks and chocolate powder. Also, it refers to the use of this form...

The present invention relates to a filmogenic dispersion that is composed of starch, plasticizer, chitosan, carboxymethylcellulose and niancinamide. In this invention, chitosan and carboxymethylcellulose act as microcarriers for vitamin B3, ensuring its stability. The present invention also relates to biodegradable films that can be obtained from s...

The present invention relates to macrostructured complexes, here called macro-PECs, obtained from chitosan and carboxymethylcellulose. These macrocomplexes proved to be efficient in removing pollutants in aqueous media, such as: yellow sunset, methylene blue, safranin, congo red, cadmium and lead. Furthermore, the macrocomplexes presented reusabili...
Article
Granular macroscopic chitosan/carboxymethylcellulose polyelectrolytic complexes (CHS/CMC macro-PECs) were produced and tested as adsorbents for six pollutants often present in wastewaters: sunset yellow (YS), methylene blue (MB), Congo red (CR) and safranin (S), cadmium (Cd2+) and lead (Pb2+). The optimum adsorption pH values at 25 °C were 3.0, 11....

The indiscriminate overconsumption of non-biodegradable packaging, particularly single-use food packaging, resulting from COVID-19 is exacerbating an age-old environmental problem. This is due to changes in consumer behavior that is concerned with safety issues when buying food, which has led to a preference for purchase in delivery and take-out. I...
Chapter
O Livro é composto por trabalhos publicados no I Congresso Brasileiro de Química dos Produtos Naturais, foi um evento que trouxe diferentes áreas importantes e atuais dentro da química dos produtos naturais e também incentivou a troca de experiências entre discentes, docentes e empresários, promovendo o desenvolvimento científico e tecnológico da c...
Article
Global growth impacts on the increased use and demand for natural resources, requiring solutions for the high volume of industrial waste and by-products generated from the most diverse commercial areas, mainly the food sector. Among the main residues with a large volume generated, those from fruit processing, grain cleaning in processing units, veg...
Article
Nowadays, the pharma and food industries have been gearing up to meet the urgent need for anti-infective and anti-inflammatory nutritional formulations. In this way, several nutraceutical compounds are being re–evaluated due to their established bioactivities. Few compounds have been or may be efficiently targeted against infections, inflammatory c...

Effects of chitosan (CHS) to carboxymethylcellulose (CMC) mixing ratio (1:0; 4:1; 3:1; 2:1; 1:1; 1:2; 1:3; 1:4; 0:1), temperature (25; 45; 65; 85 ◦C), and pH (3.0; 3.5; 4.0; 4,5) on obtaining of macro- and micro-polyelectrolyte complexes (PEC) were investigated. Mixing ratio 1:2 and 25 ◦C maximized the biopolymers’ interactions and the formation of...

Green synthesis is one of the most valuable and emerging methods for the synthesis of nanoparticles (NPs) nowadays, presenting imperative biological benefits, reduced process time, cost-effectiveness, and environmental benefits, as an alternative to physical and chemical processes. Silver, a noble metal, possess unique properties and potential appl...
Chapter
In order to replace or at least reduce the use of petroleum-based polymers, researchers have been encouraged to develop new biomaterials that explore the emerging concept of sustainable development. Chitosan is a biopolymer derived from chitin, which is widely distributed in nature and is the second most abundant polysaccharide after cellulose. Chi...
Article
New biodegradable trays based on cassava starch blended with sugarcane bagasse (SB), as the main component, and cornhusk (CH), malt bagasse (MB), or orange bagasse (OB) have been investigated. Gelatinized cassava starch solution was used as binder. The resulting trays displayed thickness between 3.505 ± 0.18 and 3.964 ± 0.52 mm and density between...
Article
New edible coatings made of cassava starch and babassu flour were applied on cagaita and mangaba, two typical fruits from the Brazilian Cerrado, by dipping method. The effect of the babassu flour concentration (10, 30, or 50 g/100 g of starch) on the properties of coated fruits were studied. Fruits treated with cassava starch coating added with 50%...
