However, due to its volatility, it becomes susceptible to degradation and loss of its characteristics. In order to overcome these difficulties and make the application of carvacrol (CA) feasible, the bioactive was microencapsulated by complex coacervation, coating the particles with polymers. For this process, gelatin (GEL) and gum arabic (GA) biololymers were chosen as wall materials and transglutaminase (TGL) as cross-linking agent. Particles with different levels of carvacrol - 40% (2g CA), 50% (2.5g CA) and 60% (3g CA) w/w - were produced in relation to the biopolymers, in order to observe the behavior of the encapsulated bioactive. The microparticles produced at different concentrations of carvacrol were evaluated for morphology, chemical structure and thermal resistance. Regarding morphology, the samples showed spherical structure and better production behavior in the GA/GEL/2.5CA sample. The particle size varied according to the increase in bioactive concentration, in a range of 468 to 608 µm. However, GA/GEL/2.5CA sample presented larger diameter distributions. All samples presented chemical characteristics that identify the presence of the bioactive in the capsules, however, the GA/GEL/2.5CA sample presented greater intensity of the existence of carvacrol. By evaluating the particles for thermal resistance, it was found that the sample GA/GEL/2.5CA showed better behavior, increasing the temperature at the beginning of degradation from 68.5°C (pure compound) to 130.7°C. When this sample cross-linked, it was observed that the transglutaminase enzyme slowed down the degradation of carvacrol by 20°C compared to the sample without cross-linking. Diversos estudos identificaram o potencial de alto interesse bioativo no carvacrol. Entretanto, devido sua volatilidade, este se torna suscetível à degradação e à perda de suas características. Com o objetivo de contornar essas dificuldades e viabilizar a aplicação do carvacrol (CA), micro encapsulou-se o bioativo por coacervação complexa, revestindo as partículas com polímeros. Para esse processo escolheu-se de biopolímeros gelatina (GEL) e goma arábica (GA), como material de parede, e transglutaminase (TGL) com agente reticulante. Foram produzidas partículas com diferentes concentrações de carvacrol – 40% (2g CA), 50% (2,5g CA) e 60% (3g CA) p/p – em relação aos biopolímeros, com a finalidade de observar o comportamento do bioativo encapsulado. Avaliaram-se as micropartículas produzidas em concentrações diferentes de carvacrol, quanto à morfologia, estrutura química e resistência térmica. Quanto à morfologia, as amostras apresentaram estrutura esférica e melhor comportamento de produção na amostra de GA/GEL/2,5CA. O tamanho de partícula variou de acordo com o aumento de concentração de bioativo, em uma faixa de 468 a 608 µm. Contudo, a amostra GA/GEL/2,5CA apresentou distribuições mais largas de diâmetro. Todas as amostras apresentaram caraterísticas químicas que identificam a presença do bioativo nas capsulas, contudo, a amostra GA/GEL/2,5CA apresentou maior intensidade de presença de carvacrol. Avaliando as partículas quanto à resistência térmica, verificou-se que a amostra GA/GEL/2,5CA apresentou melhor comportamento, aumentando a temperatura de início de degradação de 68,5°C (composto puro) para 130,7°C. Quando reticulada essa amostra, observou-se que a enzima transglutaminase retardou a degradação o carvacrol, em 20°C em relação à amostra sem reticulação. 2022-06-14T18:48:45Z 2022-06-14T18:48:45Z 2021-12-10 bachelorThesis MARIOTT, Ana Cristina.
