“…In addition to antimicrobial activity, when sophorolipids was added to the bioactive films composed of polylactic acid for food, it enhanced their thermomechanical properties [ 73 ]. In this context, SL are promising ingredients in the food industry as they also have emulsifying properties over edible oils and are stable at a wide range of pH, temperature and salinity [ 74 ].…”

Biosurfactants are in demand by the global market as natural commodities that can be added to commercial products or use in environmental applications. These biomolecules reduce the surface/interfacial tension between fluid phases and exhibit superior stability to chemical surfactants under different physico-chemical conditions. Biotechnological production of biosurfactants is still emerging. Fungi are promising producers of these molecules with unique chemical structures, such as sophorolipids, mannosylerythritol lipids, cellobiose lipids, xylolipids, polyol lipids and hydrophobins. In this review, we aimed to contextualize concepts related to fungal biosurfactant production and its application in industry and the environment. Concepts related to the thermodynamic and physico-chemical properties of biosurfactants are presented, which allows detailed analysis of their structural and application. Promising niches for isolating biosurfactant-producing fungi are presented, as well as screening methodologies are discussed. Finally, strategies related to process parameters and variables, simultaneous production, process optimization through statistical and genetic tools, downstream processing and some aspects of commercial products formulations are presented.

“…Uma forte banda próxima a 3400 cm -1 foi observada em todas as amostras, isso pode ser referente ao estiramento vibracional das hidroxilas (OH) encontradas nos soforolipídios, no amido e no glicerol (SANTOS et al, 2014;ROMANO et al, 2016;BERSANETI et al, 2016). Porém, essa banda é mais intensa na amostra de soforolipídios, indicando que o número de hidroxilas livres é reduzido nos filmes de amido, o que pode estar relacionado à participação deste grupo em ligações de hidrogênio entre o amido e os soforolipídios (SOLAIMAN et al, 2015;MANIGLIA et al, 2019;SILVEIRA et al, 2020). As bandas próximas a 1650 cm -1 podem estar relacionadas às moléculas de água embutidas na matriz do amido polimérico (SANTOS et al, 2014;BERSANETI et al, 2016), e as bandas próximo a 1750 cm -1 refere-se ao grupo carbonil lactona (C=O), presente na molécula de soforolipídios (MINUCELLI et al, 2016;SILVEIRA et al, 2020).…”

“…O amido é um biopolímero de baixo custo, alto rendimento e de fácil processamento, mas sua aplicação em filmes é dificultada por ser hidrofílico e quebradiço (WEBER, 2002;KOWALCZYK et al, 2016). Este problema pode ser solucionado com a adição de compostos anfifílicos como os soforolipídios que possuem propriedades emulsificante, umectante e plastificante ( VAN BOGAERT et al,2007;SOLAIMAN et al, 2015). Além disso, os soforolipídios apresentam propriedade antimicrobiana contra diferentes bactérias Gram positivas e Gram negativas (FRACCHIA et al, 2015;OLIVEIRA et al, 2015, FONTOURA et al, 2020.…”

RESUMOO morango é uma fruta muito suscetível à infecções por patógenos, o que reduz sua qualidade nutricional e tempo de prateleira. Uma alternativa para aumentar o prazo de validade dos morangos é a utilização de tecnologias usando filmes comestíveis incorporados à compostos antimicrobianos, como os soforolipídios. O objetivo deste trabalho foi produzir soforolipídios por Starmerella bombicola e incorporar em filmes de amido de mandioca, visando a redução da contaminação microbiana e aumento de tempo de validade do morango. As fermentações resultaram na produção de 7,6 g/L de soforolipídios, que foram utilizados para as formulações dos biofilmes. A formulação 1 continha apenas amido, a formulação 2 foi composta de amido acrescido de 5% de

Electrospun Nanosystems Based on PHBV and ZnO for Ecological Food Packaging

The electrospun nanosystems containing poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and 1 wt% Fe doped ZnO nanoparticles (NPs) (with the content of dopant in the range of 0–1 wt% Fe) deposited onto polylactic acid (PLA) film were prepared for food packaging application. They were investigated by scanning electron microscopy (SEM), energy dispersive X-ray (EDX), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), antimicrobial analysis, and X-ray photoelectron spectrometry (XPS) techniques. Migration studies conducted in acetic acid 3% (wt/wt) and ethanol 10% (v/v) food simulants as well as by the use of treated ashes with 3% HNO3 solution reveal that the migration of Zn and Fe falls into the specific limits imposed by the legislation in force. Results indicated that the PLA/PHBV/ZnO:Fex electrospun nanosystems exhibit excellent antibacterial activity against the Pseudomonas aeruginosa (ATCC-27853) due to the generation of a larger amount of perhydroxyl (˙OOH) radicals as assessed using electron paramagnetic resonance (EPR) spectroscopy coupled with a spin trapping method.
