The composite flours were formulated with bean flour (80%) and nixtamalized corn flour (20%) using xanthan gum and/or ascorbic acid in different concentrations (0, 0.25 and 0.50%). The different flours composed of beans/corn were evaluated for their water absorption capacity (2.68 to 3.84 g/g), oil absorption capacity (1.14 to 1.43 g/mL) and swelling capacity (10.57 to 10.98 mL/g). The different flours composed of beans/corn were used for the production of pound cakes. As the content of xanthan gum and/or ascorbic acid increased, the different pound cakes presented better weight, volume and volume index. Likewise, the nutritional quality of the pound cake is improved, compared to the flour used individually.","PeriodicalId":200063,"journal":{"name":"Journal of Enviromental Sciences and Natural Resources","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129928670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meliponiculture is a very important activity for some Mayans in the Yucatan Peninsula. However, the production of Melipona honey and its territorial distribution has decreased in recent decades, compared to the last century. Fieldwork was carried out in the east of the state of Yucatan to assess honey production activities and the socioeconomic situation of the population that depends on them. Data from Worldclim was used to generate distribution models for Melipona bees as well as scenarios of the impact of climate change on these species in the next seven decades. The scenarios that assume the continued presence of Melipona bees in the next seven decades show disappointing results in the face of climate change. It is necessary to implement effective public policies that help promote the well-being of both Melipona bees and the population that depends on them.","PeriodicalId":200063,"journal":{"name":"Journal of Enviromental Sciences and Natural Resources","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129977837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morphometric parameters of length, width, thickness, weight and volume were measured; An aqueous maceration of the bean seeds was carried out in an acid medium (0.1 M HCl) and the content of polyphenols (Folin Ciocalteu Method), anthocyanins (visible spectrophotometry) and determination of the Reducing Iron Power (FRAP, by the method of TPTZ) of the aqueous extracts. It was found that the concentration of anthocyanins correlates with the total content of polyphenols and with the reducing activity of the ferric ion, the aqueous extracts obtained had a content of total phenols of 413 mg EAG/100g of seed, of anthocyanins of 42 mg MGE/100 g of seed and an iron reducing power of 10.26 mol of Fe2+/g of seed.
