Processing Properties

Starch is the second most abundantly available natural polymer in the world, after cellulose. If we add its biodegradability and non-toxicity to the natural environment, it becomes a raw material very attractive for the food and non-food industries. However, in the latter case, mainly due to the high hydrophilicity of starch, it is necessary to carry out many more or less complex operations and processes. One of the fastest growing industries in the last decade is the processing of biodegradable materials for packaging purposes. This is mainly due to awareness of producers and consumers about the dangers of unlimited production and the use of non-degradable petroleum polymers. Therefore, in the present review, an attempt was made to show the possibilities and limitations of using starch as a packaging material. The most important physicochemical features of this biopolymer are discussed, and special attention is paid to more or less environmentally friendly methods of improving its processing properties.

A Batata doce é largamente utilizada na alimentação humana, animal e como matéria-prima nas indústrias de alimentos. É consumida por muitos povos pelo mundo tendo importante participação histórica em várias culturas. Nutricionalmente, no contexto da saúde humana, a espécie apresenta ingredientes considerados úteis na prevenção e melhora dos sintomas diabéticos, é comumente relacionada ao ganho energético e de massa muscular por atletas e praticantes de fisiculturismo, considerando a importância desta planta, este trabalho objetivou avaliar diferentes variedades de batata doce, quanto ao teor de proteínas e amido. Para alcançar este objetivo foram utilizadas quatro variedades de batatas, ambas encontradas na região de Guarapuava: (1) casca rosada e polpa amarela; (2) casca escura polpa branca (3) casca branca polpa branca; (4) casca roxa polpa creme, estas analisadas em triplicata. Obteve-se 17,8 % de amido pelo peso total da variedade (1) e 7,8% de proteínas; 11,2% de amido na variedade (2) e 5,8% de proteínas totais; 9,2% (amido) e 5,2% (proteínas) na variedade (3) e 7,5% (amido) e 5,8% (proteínas) na variedade (4). Isso leva a concluir que tal variação é uma constante e que variedades diferentes sempre apresentaram diferentes teores de proteínas e amidos, o que permite afirmar que antes de considerar a batata doce como alimento funcional se deve avaliar as características bioquímicas e nutricionais das diferentes variedades existentes.Palavra-chave: Tuberosa.

Blackcurrant is a healthy, affordable, and traditionally gardened berry that, thus far, has been underused in food applications. From the consumers’ point of view, the acidic taste of blackcurrants is a challenge; therefore, these berries have mainly been utilized for sugary juice production. This research study aimed to develop a frozen vegan blackcurrant product with pleasant sensory properties and potential probiotic function. A candidate probiotic, Lactoplantibacillus plantarum Q823, was used in the manufacturing process. The physicochemical properties, nutritional composition, and consumer preference for the developed product were assessed, as was the viability of L. plantarum Q823 during storage time and in an in vitro gastrointestinal model. Consumers (n = 71) perceived the developed product to be pleasant. L. plantarum Q823 had high viability counts (log colony forming units (cfu) g−1 7.0 ± 0.38) in the final product, although the viability of L. plantarum Q823 during storage time needs to be enhanced to obtain a probiotic product. Thus, within an optimized formulation, blackcurrant berries represent a potential raw material for functional frozen food products.

The fascinating world of lichens draws the attention of the researchers because of the numerous properties of lichens used traditionally and, in modern times, as a raw material for medicines and in the perfumery industry, for food and spices, for fodder, as dyes, and for other various purposes all over the world. However, lichens being widespread symbiotic entities between fungi and photosynthetic partners may acquire toxic features due to either the fungi, algae, or cyano-procaryotes producing toxins. By this way, several common lichens acquire toxic features. In this survey, recent data about the ecology, phytogenetics, and biology of some lichens with respect to the associated toxin-producing cyanoprokaryotes in different habitats around the world are discussed. Special attention is paid to the common toxins, called microcystin and nodularin, produced mainly by the Nostoc species. The effective application of a series of modern research methods to approach the issue of lichen toxicity as contributed by the cyanophotobiont partner is emphasized.

Music cannot be separated from its historical, geographical, and cultural context; therefore, it is important that students be taught music from a variety of genres, cultures, and historical periods relevant to the music to which they are introduced. In this article, I introduce an interdisciplinary approach through contextualization of the content of music, using it to lead to the study of related works in various disciplines. Using a song inspired by Indonesia’s Solo River, a lesson sample demonstrates teaching strategies that motivate students to engage in integrative thinking. By exploring music’s connection with relevant subjects to teach about the natural environment, this contextualized lesson presents a global learning experience to broaden students’ knowledge of the world. Contextualizing the content of Bengawan Solo illustrates how history and culture shaped the song and demonstrates how this work can be used as a springboard for students’ exploration of its history, geography, and ecology.

All over the world, a large proportion of the population consume insects as part of their diet. In Western countries, however, the consumption of insects is perceived as a negative phenomenon. The consumption of insects worldwide can be considered in two ways: on the one hand, as a source of protein in countries affected by hunger, while, on the other, as an alternative protein in highly-developed regions, in response to the need for implementing policies of sustainable development. This review focused on both the regulations concerning the production and marketing of insects in Europe and the characteristics of edible insects that are most likely to establish a presence on the European market. The paper indicates numerous advantages of the consumption of insects, not only as a valuable source of protein but also as a raw material rich in valuable fatty acids, vitamins, and mineral salts. Attention was paid to the functional properties of proteins derived from insects, and to the possibility for using them in the production of functional food. The study also addresses the hazards which undoubtedly contribute to the mistrust and lowered acceptance of European consumers and points to the potential gaps in the knowledge concerning the breeding conditions, raw material processing and health safety. This set of analyzed data allows us to look optimistically at the possibilities for the development of edible insect-based foods, particularly in Europe.

Artemisia Species

The genus Artemisia, often known collectively as “wormwood”, has aroused great interest in the scientific community, pharmaceutical and food industries, generating many studies on the most varied aspects of these plants. In this review, the most recent evidence on health effects of edible Artemisia species and some of its constituents are presented and discussed, based on studies published until 2020, available in the Scopus, Web of Sciences and PubMed databases, related to food applications, nutritional and sesquiterpene lactones composition, and their therapeutic effects supported by in vivo and clinical studies. The analysis of more than 300 selected articles highlights the beneficial effect on health and the high clinical relevance of several Artemisia species besides some sesquiterpene lactones constituents and their derivatives. From an integrated perspective, as it includes therapeutic and nutritional properties, without ignoring some adverse effects described in the literature, this review shows the great potential of Artemisia plants and some of their constituents as dietary supplements, functional foods and as the source of new, more efficient, and safe medicines. Despite all the benefits demonstrated, some gaps need to be filled, mainly related to the use of raw Artemisia extracts, such as its standardization and clinical trials on adverse effects and its health care efficacy.
