ABSTRACT
This study aimed to prepare artisanal tomato sauce (TSC, control) containing 10% (TS10) or 20% (TS20) of whole green banana biomass (GBB). Tomato sauce formulations were evaluated for storage stability, sensory acceptability, and color and sensory parameters correlations. Data were subjected to Analysis of Variance, followed by the comparison of means by Tukey's test (p < 0.05 and p < 0.01). Correspondence analysis was used to assess the responses to a Check-All-That-Apply questionnaire. A significant effect was observed (p > 0.05) for the interaction between storage time and GBB addition on all physicochemical parameters. GBB reduced titratable acidity and total soluble solids (p < 0.05), possibly because of its high content of complex carbohydrates. All tomato sauce formulations had adequate microbiological quality for human consumption after preparation. Sauce consistency increased with increasing GBB concentrations, improving the sensory acceptance of this attribute. All formulations achieved the minimum threshold for overall acceptability (70%). A thickening effect was observed with the addition of 20% GBB, resulting in significantly (p < 0.05) higher body, higher consistency, and reduced syneresis. TS20 was described as firm, very consistent, light orange in color, and very smooth. The results support the potential of whole GBB as a natural food additive.

Edible insects are a solid alternative to meet the growing demand for animal protein. However, there are doubts regarding the safety of insect consumption. Mycotoxins are substances of concern for food safety, as they may cause harmful effects on the human organism and accumulate in the tissues of some animals. This study focuses on the characteristics of the main mycotoxins, the mitigation of human consumption of contaminated insects, and the effects of mycotoxins on insect metabolism. To date, studies reported the interaction of the mycotoxins aflatoxin B1, ochratoxin A, zearalenone, deoxynivalenol, fumonisin B1, and T-2, isolated or combined, in three insect species from Coleoptera and one from Diptera order. The use of rearing substrates with low mycotoxin contamination did not reduce the survival and development of insects. Fasting practices and replacing contaminated substrate with a decontaminated one decreased the concentration of mycotoxins in insects. There is no evidence that mycotoxins accumulate in the tissues of the insects' larvae. Coleoptera species showed high excretion capacity, while Hermetia illucens had a lower excretion capacity of ochratoxin A, zearalenone, and deoxynivalenol. Thus, a substrate with low mycotoxin contamination could be used for raising edible insects, particularly from the Coleoptera order.

Anthocyanins are naturally colored compounds that can be extracted from plants, especially fruits. Their molecules are unstable under normal processing conditions; thus, they must be protected using modern technologies, such as microencapsulation. For this reason, many industries are searching for information from review studies to find the conditions that improve these natural pigments' stability. This systematic review aimed to elucidate different aspects of anthocyanins, such as main extraction and microencapsulation methods, gaps in analytical techniques, and industrial optimization measurements. Initially, 179 scientific articles were retrieved, of which seven clusters were found with 10-36 cross-linked references. Sixteen articles containing 15 different botanical specimens were included in the review, most focusing on the whole fruit, pulp, or subproducts. The extraction and microencapsulation technique resulting in the highest anthocyanin content was sonication with ethanol, temperature below 40 °C, and maximum time of 30 min, followed by microencapsulation by spray drying with maltodextrin or gum Arabic. Color apps and simulation programs may help verify natural dyes' composition, characteristics, and behavior.

The inappropriate use of synthetic antibiotics has become a global public health problem. Therefore, the study of new alternatives for the treatment of infectious diseases is relevant and natural bioactive products are on the rise. This study conducted a scientific prospection of bioactive natural products with promising applications in the chemical control of microorganisms. A systematic review of the most recent articles was performed according to the following three steps: (i) eligibility assessment, (ii) screening, and (iii) inclusion of articles and information extraction. There has been an increase in the number of scientific publications on bioactive natural products for microbial control in the CAPES and SciELO databases (2001-2021). Seventeen relevant articles were included, most of which focused on extracts. Ascorbic acid, chlorogenic acid, chrysin, and quercetin were the most cited compounds. Natural products were shown to be effective in inhibiting more than 30 microorganisms. A discussion was presented on the research trends.

Maltodextrin (DE 20) and gelatin (4:1, w/w, respectively) were investigated as encapsulant materials for lemongrass (Cymbopogon citratus DC. Stapf) essential oil microencapsulation by freeze-drying. Three formulations were prepared: M1 (5% essential oil), M2 (10% essential oil), and M3 (15% essential oil), all in w/w. Microparticles were characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy, water activity measurement, thermogravimetric and derivative thermogravimetric analysis, differential scanning calorimetry, and antioxidant activity analysis. Yield and microencapsulation efficiency were also determined. The results showed the promising potential of maltodextrin and gelatin as encapsulants and confirmed the feasibility of preparing C. citratus essential oil microparticles by freeze-drying. Microencapsulation improved the oil's thermal and oxidative stability, providing protection from volatilization and environmental conditions. Scanning electron microscopic examination of M1 revealed a closed, pore-free surface. M1 had higher yield and microencapsulation efficiency, showing great commercial potential for its reduced storage, transport, and distribution costs.

Objetivou-se desenvolver e avaliar sensorialmente doces em massa de graviola com substituição parcial da sacarose por xarope de glicose. As formulações de doces foram elaboradas variando a concentração de xarope de glicose em substituição a sacarose. A análise sensorial foi aprovada pelo comitê de ética em pesquisa da Universidade Estadual da Paraíba. Os doces apresentaram cor, aroma e sabor característicos do fruto. Percebeu-se que a aceitação sensorial apresentou semelhança significativas entre as formulações e boa impressão global, ficando com média que remete a gostei moderadamente. Todas as formulações alcançaram valores satisfatórios para a avaliação sensorial, sendo a formulação com substituição parcial de 19,70% a que apresentou maior aceitação.

Objetivou-se com a presente pesquisa elaborar e caracterizar a composição físico-química de refresco de amora-preta adoçado com mel. Para a elaboração dos refrescos foram utilizados polpa de amora-preta extraída de frutos in natura e mel de abelha Apis Mellifera L., sendo processados em liquidificador industrial e acondicionados em garrafas plásticas de polietileno sob refrigeração. Os refrescos, a polpa e o mel utilizados foram submetidos às análises físico-químicas de acidez total titulável, sólidos solúveis totais, pH, Ratio, atividade de água, cinzas e umidade. Constatou-se que a polpa e mel utilizados na elaboração das bebidas encontravam-se conforme a legislação e foi possível elaborar refrescos de amora-preta com adição de mel, agregando valor as matérias-primas.

O constante aumento no número de estabelecimentos alimentícios como forma de obtenção de renda, associado à inexperiência dos produtores iniciantes, vem colocando em risco a segurança alimentar do consumidor. Neste contexto, objetivou-se com este estudo avaliar e discutir as condições higiênico-sanitárias e a aplicação das Boas Práticas de Manipulação em quiosques localizados na cidade de Pombal-PB. Para isso, foi aplicado Check List adequado para análise das Boas Práticas de Manipulação, conforme a RDC n° 275 e RDC nº 216. Verificou-se que os quiosques avaliados mostraram-se em condições inadequadas para o funcionamento devido inconformidades com a maioria dos parâmetros aplicados, tornando-se necessária uma maior fiscalização por parte dos órgãos competentes.
