摘要

全球人口的迅速和前所未有的扩张突出了人们对粮食资源是否充足以维持这种增长的担忧。为了满足消费者的营养需求，本研究调查并证实了可再生食物资源的可行性。利用三种可食用水草，helencha (Enhydra ans)， malancha (Alternanthera philoxeroides)和kalmi (Ipomoea aquatica)生产可食用纸张。分析了水草原料和纸张样品的组成，包括近似值组成、氨基酸含量、矿物质和重金属含量以及生物活性化合物。水草和纸的成分相近，碳水化合物含量最高(50.38 ~ 64.63%)，其次是粗蛋白质(15.25 ~ 19.13%)、灰分(9.30 ~ 15.88%)和脂肪(1.55 ~ 3.43%)。粗草和纸张中Na、Ca和Zn的含量分别为27.7 ~ 30.4 mg/100 g、126.8 ~ 489.65 mg/100 g和4.5 ~ 16.3 mg/100 g。包括镍、铅和铜在内的重金属含量都在可接受的范围内。纸上含有七种必需氨基酸和八种非必需氨基酸。必需氨基酸中苯丙氨酸含量最高，为2735.9 mg/100 g，其次为蛋氨酸，为2377.29 mg/100 g，组氨酸含量为1972.6 mg/100 g。水草纸中总氨基酸含量最高(16146.81 mg/100 g)，水草纸含量最低(13118.67 mg/100 g)。水草纸中含有丰富的生物活性物质，水草纸、水草纸和水草纸中氨基酸含量分别为31、33和40个。与生杂草相比，纸制水草的营养成分没有明显变化，这表明其作为营养和生物活性化合物的来源的生产和消费前景广阔。

A Green Approach to Valorizing Abundant Aquatic Weeds for Nutrient-Rich Edible Paper Sheets Production in Bangladesh

The rapid and unprecedented expansion of the global population highlights concerns about the sufficiency of food resources to sustain this growth. This study investigates and substantiates the feasibility of renewable food resources in order to meet the nutritional requirements of consumers. Three edible aquatic weeds, helencha (Enhydra fluctuans), malancha (Alternanthera philoxeroides), and kalmi (Ipomoea aquatica), were used to produce edible paper sheets. The composition of the raw aquatic weeds and paper sheet samples was analyzed, including the proximate composition, amino acid content, minerals and heavy metal contents, and bioactive compounds. The dried raw aquatic weeds and paper sheets showed similar proximate compositions, with carbohydrates being the highest component (50.38–64.63%), followed by crude protein (15.25–19.13%), ash (9.30–15.88%), and lipid (1.55–3.43%). The raw weeds and paper sheets were rich in essential minerals like Na, Ca, and Zn with contents ranging from 27.7 mg/100 g to 30.4 mg/100 g, 126.8 mg/100 g to 489.65 mg/100 g, and 4.5 mg/100 g to 16.3 mg/100 g, respectively. Acceptable levels of heavy metals, including Ni, Pb, and Cu, were found. The paper sheets contained seven essential and eight non-essential amino acids. Among the essential amino acids, the phenylalanine content was the highest at 2735.9 mg/100 g in E. fluctuans paper sheets, followed by methionine at 2377.29 mg/100 g in the raw E. fluctuans and histidine at 1972.6 mg/100 g in E. fluctuans paper sheets. A. philoxeroides sheets showed the highest total amino acid content (16,146.81 mg/100 g), while I. aquatica showed the lowest (13,118.67 mg/100 g). The aquatic weed paper sheets were rich in bioactive compounds, and the numbers in E. fluctuans, A. philoxeroides, and I. aquatica paper sheets were 31, 33, and 40, respectively. There were no significant changes in the nutritional content of the aquatic weeds in paper sheet form compared with the raw weeds, which suggests promising prospects for their production and consumption as a source of nutrition and bioactive compounds.

期刊介绍： This journal publishes papers that aid in the development, demonstration, and commercialization of cleaner products and processes as well as effective environmental policy strategies. As its title suggests, the journal has two major thrusts: Clean Technologies and Environmental Policy. The Clean Technology thrust addresses the science and engineering of clean technologies. Moreover, it examines mathematical and computer-based methods and models for designing, analyzing, and measuring the cleanliness of products and processes. The Environmental Policy thrust covers research advances in scientific, social, behavioral, and economics disciplines that are relevant to complex environmental policy issues. In addition to research papers, the journal offers policy-oriented commentaries from world renowned leaders in environmental technology and policy research. It also features special issues focusing on topics of international concern.
