“…O estudo realizado por Kayode et al (2018) teve como objetivo identificar a atividade antimicrobiana do óleo essencial de Adansonia digitata no controle pós-colheita da deterioração Contribuciones a Las Ciencias Sociales, São José dos Pinhais, v.17, n.4, p. 01-20, 2024 do tomate. A avaliação da atividade antimicrobiana do óleo contra a decomposição pós-colheita de frutos de tomate, armazenados em temperatura ambiente (27±2 °C), indicou uma redução significativa (P < 0,05) das cargas bacterianas e fúngicas a 2.000 ppm, em comparação com o controle.…”

A sustentabilidade da indústria agroalimentar é uma necessidade global, e os países em desenvolvimento enfrenta mais riscos, devido às desvantagens tecnológicas e aos fenômenos de alterações climáticas. No entanto, fungos e bactérias patogênicas são os responsáveis fundamentais pela deterioração da qualidade e da composição de nutrientes e pela contaminação por micotoxinas dos produtos, afetando sua conservação, vida útil e valor comercial. Tendo em conta que o processo pós-colheita está centrado na segurança alimentar e na conservação das propriedades dos alimentos, o estudo sobre a desinfecção de bactérias de origem alimentar, que ameaçam a saúde dos consumidores, está entre os aspectos que devem ser considerados. Para garantir alimentos seguros e de qualidade, diferentes métodos físicos, químicos e biológicos estão sendo desenvolvidos. Nessa perspectiva, o presente trabalho tem como objetivo investigar os óleos essenciais como agentes antimicrobianos com potencial aplicação no contexto pós-colheita em frutíferas. Recorreu-se, portanto, à pesquisa qualitativa, exploratória e revisão integrativa de seis artigos científicos no idioma inglês, publicados no SciELO, Web of Sciene, Scopus, Science Direct e no Google Acadêmico. Dentre os óleos essenciais estudados, notáveis avanços foram observados com o óleo de Adansonia digitata, bem como os óleos cítricos, como o de limão, laranja e tangerina. Quanto aos micróbios abordados, Staphylococcus aureus, Escherichia coli, Listeria monocytogenes, e patógenos fúngicos fitopatogênicos foram alguns dos principais alvos nos estudos revisados. Evidencia-se, portanto, que a utilização de óleos essenciais como agentes antimicrobianos em processos pós-colheita apresenta-se como uma alternativa promissora e ecologicamente sustentável para controlar patógenos.

“…Fruit pulps (dried) of A. digitata were obtained from Khartoum city, Sudan from different grain markets. The essential oil was extracted from the powder using a Clevenger apparatus and hydro-distillation process according to the British Pharmacopoeia Specifications 18 . In brief, fruit dried materials (2000 g) were properly washed, chopped, and mixed with 5 liter of distilled water (DW) inside the distillation flask.…”

The beneficial effect of Adansonia digitata products success to modulate lipid profiles and inhibit LDL oxidation in-vitro: An associational study

et al. 2022

BackgroundThere is a growing interest in medicinal plants in recent years due to their many therapeutic benefits and low side effects. Among the medicinal plants is the African Adansonia digitata (baobab) that has edible fruit. In the current study, the effect of A. digitata juice consumption on the lipid profile was investigated. In addition, inhibition of the oxidation of low-density lipoprotein cholesterol (LDL-C) in-vitro by A. digitata essential oil (EO) was also investigated. MethodsIn this cohort study, a total of 70 subjects of A. digitata users (AD group, 42 male and 28 female) and 70 non A. digitata users (Non-AD group, 44 male and 26 female) were recruited to participate in this study. We evaluated lipid profile, HbA1c, liver/kidney functions, and phytosterol contents in fasting blood samples of all participants.ResultsThe present findings illustrated significantly lower levels of total cholesterol, triglycerides, and LDL in the AD group compared to Non-AD (p < 0.01). In addition, essential oil of A. digitata inhibited LDL oxidation in-vitro as shown by the significant decreases in the formation of malonaldehyde (MDA), protein carbonyl (PC), and lipid hydroperoxide (LHP) (P<0.05). No significant changes in fasting blood glucose, HbA1c, HDL, kidney function, and liver function enzymes between the two groups were detected (P>0.05). ConclusionThe juice of A. digitata has hypolipidemic and antioxidative effects and might be beneficial for the management of lipid levels in the body.

“…5 Tomatoes are more susceptible to fungal contamination due to high moisture content and their thin outer layer. 6,7 Due to worldwide consumption of tomatoes, the presence of any harmful mycotoxin or fungal contamination can affect public health. The common tomato-contaminating fungi are Fusarium spp., Aspergillus spp., Rhizopus spp., Penicillium spp., and Alternaria spp.…”

Prevalence of fungi in fresh tomatoes and their control by chitosan and sweet orange (Citrus sinensis) peel essential oil coating

BACKGROUND: Fungal contamination is a major cause of food spoilage. There is an urgent need to find and characterize natural preservatives. This study evaluates the prevalence of fungi in tomatoes and their control by using essential oil (EO) from sweet orange peel. Essential oils were extracted from dried and fresh sweet orange peels by using n-hexane and ethanol as extraction solvents. Fourier transform infrared spectroscopy (FTIR) and gas chromatography-mass spectrometry (GC-MS) analyses were performed to identify the chemical composition of the EO. A combination of chitosan (CS) and EO was used to control the fungal decay of tomatoes inoculated with Aspergillus niger and Penicillium citrinum.RESULTS: Tomatoes obtained from local markets and supermarkets showed a high prevalence of Aspergillus and Penicillium spp. Essential oils extracted by ethanol from dried peels showed complete inhibition of A. niger and P. citrinum and hyphal degradation at a minimum inhibitory concentration (MIC) of 100 ∼L mL −1 . The combination of EO with chitosan (2%) as a coating, effectively controlled the fungal decay of tomatoes until the eighth day of storage at 25 °C.CONCLUSION: Due to their edible nature, and their antifungal and preservative potential, EO-and CS-based coatings can be used to extend the shelf life of tomatoes and other agriculture commodities. Essential oil-and CS-based coating can be used as alternative to synthetic preservatives, which are associated with various health hazards.
