    (2025) Barreto, Neyse Natália dos Santos; Chaves, Taciana Carneiro; Chaves, Taciana Carneiro; Gois, Georgia Nayane Silva Belo; Silva, Marina de Magalhães
    This article aims to analyze essential oils, volatile compounds rich in terpenes and phenols, highlighting their multiple applications and quality challenges. Considering their relevance in aromatherapy, pharmaceutical and cosmetic industries, agriculture, and food products, the study demonstrates how environmental factors, plant parts used, and extraction methods directly influence their properties. For this, a literature review was carried out using books, undergraduate theses, dissertations, doctoral theses, and articles available on academic platforms such as Science Direct, Scopus, Scielo, and Google Scholar. The analysis highlights the importance of quality control through techniques like GC-MS to ensure purity and safety, particularly in therapeutic applications. Although Brazil faces challenges in standardizing this market, the growing demand for natural products is driving the adoption of stricter regulations. It is concluded that the full use of the sustainable potential of essential oils depends on the integration between scientific research, technological development, and appropriate regulatory frameworks, aiming for safe and effective applications in various sectors.

    (Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2021-10-22) Nascimento, Alailson Araújo do; Oliveira, André Luiz dos; Oliveira, André Luiz dos; Rocha, Martha Suzana Rodrigues dos Santos; Chaves, Taciana Carneiro
    Agriculture is of significant importance to the economy of Alagoas, but its expansion generates an indiscriminate use of pesticides, causing impacts on agricultural practices and on the population of the state. Therefore, it is necessary to reduce the consumption of pesticides and use agrarian practices with natural foods, in order to generate a better quality of life. I this regard, on the massive use of pesticides in agroecosystems, as well as the consequent impacts of this type of product on the environment and society, this monograph objectifies the need for legislative sanitary actions consistent with the control, assistance to populations and exposed agricultural areas to pesticides. This is a literature review study in the State of Alagoas, with information from the National Health Surveillance Agency (ANVISA) and the Agricultural Defense and Inspection Agency of Alagoas (ADEAL). The largest sector in agriculture in Alagoas, sugarcane, which occupies 453 thousand ha, was observed the use of pesticides such as herbicides, fungicides and insecticides, the chemical group of glycines, bipyridyls, strobilurins and neonicotinoids, causing environmental problems and diseases. Some inconsistencies were identified on the inspection of health policies, however the exemption from the Tax on the Circulation of Goods and Provision of Services (ICMS) allowed greater freedom of use, making them common, directly implying the better development of agricultural activities in the economy of Alagoas, above all there is sustainable production free of pesticides, organic agriculture, which is part of family farming, thus allowing for a natural handling of food as well as improving the quality of human and environmental life.

    Análise físico-química do mel de abelha produzido pela Associação Amapin no município de Igreja Nova - AL
    (2024) Santos, Geovana Estefany dos; Silva, Marina de Magalhães; Silva, Marina de Magalhães; Leão, Maurício de Andrade; Chaves, Taciana Carneiro
    For hundreds of years, bee honey has been explored by humans and used as a natural food that is extremely beneficial for health and has a high nutritional content. Brazil is one of the countries that produces the most honey, this high production is due to flora and climate variation, essential factors for its production. The municipality of Igreja Nova, belonging to the state of Alagoas, located in the northeast region of the country, presents conditions that contribute to beekeeping practices, but the lack of studies on the subject means that producers have difficulty characterizing this product. In this sense, the present work aimed to analyze the bee honey produced by one of the beekeepers of the Associação de Meliponicultores e Apicultores de Igreja Nova (AMAPIN). To this end, the parameters determined were: pH, humidity, total soluble solids (TSS), titratable acidity and reducing sugars. The samples had a pH varying between 4.3 and 6.7. For SST's, the samples presented values that corroborate the literature. For humidity, honey samples from July to October showed a high concentration of water, while those from November and December were in accordance with the standard. For acidity values, all were within the limits established by legislation and in relation to the concentration of reducing sugars, none of the samples were within the required limits, which may be related to several factors, including the floral origin of the nectar and the premature harvest. Thus, it was possible to conclude that the honey analyzed was of good quality, despite not following all the standards established by legislation, referring to Normative Instruction Nº. 11, dated 10/20/2000 of the Ministry of Agriculture, Livestock and Supply – MAPA.

    Impactos causados pela queima na cultura da cana-de-açúcar no estado de Alagoas: uma revisão integrativa da literatura
    (2024) Santos, Jadson Farias; Chaves, Taciana Carneiro; Chaves, Taciana Carneiro; Góis , Geórgia Nayane Silva Belo; Silva, Marina de Magalhães
    The adaptability and transformation capacity of the sugarcane industry in Brazil has kept the culture as an important economic sector, being responsible for millions of jobs as well as foreign exchange for the country, whether in the export of traditional sugar or the modern ethanol fuel. During the various phases of development of this industry, some environmental impacts have been triggered. In this context, this study aimed to conduct an integrative literature review on the impacts caused by the burning of sugarcane in the state of Alagoas. Searches were carried out in electronic databases such as: (1) Science Direct; (2) Lilacs; (3) Scopus; (4) Scielo; (5) Google Scholar; (6) OATD (Open Access Theses and Dissertations); (7) BDTD (Brazilian Digital Library of Theses and Dissertations); (8) La Referencia Red de Repositorios de Acceso Abierto a la Ciencia; (9) NDLTD (Networked Digital Library of Theses and Dissertations); and (10) BASE (Bielefeld Academic Search Engine). After searching the literature on the impacts caused by burning in sugarcane culture in the state of Alagoas, 600 published works were identified. Among the 600 works, only 11 were eligible to compose the integrative review study. In general, most of the eligible studies were developed by the Federal University of Alagoas. Additionally, it was observed that the expansion of monoculture has led to rural exodus, land concentration, and biodiversity loss. Despite technological advances adopted by sugar mills to mitigate these impacts, such as the reuse of waste and the adoption of more sustainable agricultural practices, the challenges of ensuring environmental and social sustainability remain. This study reinforces the importance of a more integrated and sustainable production model that considers not only economic benefits but also environmental and social effects, promoting a better quality of life for local communities and contributing to the preservation of natural resources.

    (2024) Felix, Gustavo Santos; Chaves, Taciana Carneiro; Cunha, Simonise Figueiredo Amarante; Cunha, Simonise Figueiredo Amarante; Chaves, Taciana Carneiro; Dacal, Ruth Germaine Vrijdags
    The state of Alagoas, located in the Northeast region of Brazil, has a long-standing tradition in the cultivation of sugarcane and the production of first-generation sugar and ethanol. The state comprises 23 municipalities that have plants dedicated to ethanol production. However, this sector faces various challenges and opportunities: the sugar-energy industry in Alagoas struggles with issues such as low sugarcane productivity and a lack of investment in technology and infrastructure; nevertheless, it seeks to adapt to new market demands and environmental requirements. Ethanol production in Alagoas was traditionally based on the use of sugarcane juice, which is fermented and distilled to obtain the biofuel. Currently, corn is also used as a raw material, with Cooperativa Pindorama, located in the municipality of Coruripe, being the first plant in the state of Alagoas to produce ethanol from corn. Thus, to describe the ethanol production situation in the state, the general objective was to present the historical and current context of ethanol production in Alagoas, highlighting its challenges and its economic, social, and environmental importance for the state. To achieve these objectives, a descriptive research methodology with a qualitative approach was adopted, describing the historical and current context of the state. Based on the collected information, it is possible to conclude that the ethanol production sector in Alagoas is in a consolidated and efficient stage, although some complications still exist.
