The surfaces of grapes are covered by different yeast species that are important in the first stages of the fermentation process. In recent years, non-Saccharomyces yeasts such as Torulaspora delbrueckii, Lachancea thermotolerans, Metschnikowia pulcherrima, and Pichia kluyveri have become popular with regard to winemaking and improved wine quality. For that reason, several manufacturers started to offer commercially available strains of these non-Saccharomyces species. P. kluyveri stands out, mainly due to its contribution to wine aroma, glycerol, ethanol yield, and killer factor. The metabolism of the yeast allows it to increase volatile molecules such as esters and varietal thiols (aroma-active compounds), which increase the quality of specific varietal wines or neutral ones. It is considered a low- or non-fermentative yeast, so subsequent inoculation of a more fermentative yeast such as Saccharomyces cerevisiae is indispensable to achieve a proper fermented alcohol. The impact of P. kluyveri is not limited to the grape wine industry; it has also been successfully employed in beer, cider, durian, and tequila fermentation, among others, acting as a promising tool in those fermentation processes. Although no Pichia species other than P. kluyveri is available in the regular market, several recent scientific studies show interesting improvements in some wine quality parameters such as aroma, polysaccharides, acid management, and color stability. This could motivate yeast manufacturers to develop products based on those species in the near future.

Phytochemical and nutritional potentials of various parts (leaf, stem and root) of Talinum triangulare were evaluated using standard techniques. Analysis of Variance (ANOVA) was employed in data analysis. All the parts of the species were found to contain nutrient compositions in varying levels. Dry matter and carbohydrate were highest in the stem (91.69±0.12 and 68.66±0.01) respectively. Moisture, ash content and crude fibre were highest in the root (9.78±0.04, 17.53±0.11and 15.32±0.03) respectively while ether extract and crude protein were highest in the leaf (1.09±0.01 and 17.72±0.17) respectively. The results showed also varying quantities of the phytochemicals in the leaf, stem and root with some parts lacking some of the phytochemicals. The leaf contained the highest percentage of all the phytochemical investigated alkaloid, flavonoid, tannin, sterol, Terpenoid, phenol and saponin (0.47±0.01, 0.26±0.00, 0.36±0.07, 0.03±0.01, 0.42±0.02, 0.02±0.01and 0.68±0.05 respectively. The root lacked sterol and phenol while stem lacked only phenol. The leaf, stem and root lacked cyanogenic glycoside. The results have indicated that these parts of the Talinum triangulare investigated are very nutritious and possessed bioactive compounds that could be extracted for the manufacture of new drug, food supplements and also be used in ethnomedicine for the treatment of diseases.

content and total peptide content were investigated in the non-farmed freshwater apple snail (Pila ampullacea) to understand its nutritional potential as alternative umami taste enhancer. Apple Snail samples with removed gut content were collected from a local snail non-farm in Surabaya City. Papain enzyme was used. The two variables, hydrolysis time (3, 6, 9, 12, 15, 18 h) and enzyme concentration (1%, 5%, 10%), was used to produce the apple snail hydrolysate. The result showed that total soluble protein was about 2.1%-7.3%, whereas total peptide content was 5.05-15.73mg/ml. The highest total soluble protein was achieved at 12 hour. Longer hydrolysis time significantly effect on total peptide content of apple snail hydrolysate.

A economia popular e solidária se opõe à superexploração do trabalho e à exploração dos recursos naturais efetivadas de maneira predatória como vem historicamente ocorrendo. Essa economia busca, entretanto, promover o desenvolvimento local e o crescimento socioeconômico em harmonia com proteção à natureza. A alimentação da humanidade atualmente se limita a apenas cerca de 110 espécies vegetais. Enquanto isso, muitas espécies ruderais, também consideradas invasoras ou pragas, além de importância ecológica, apresentam potencial alimentício, muitas vezes, já comprovado através de estudos. Em que pese a pouca divulgação desses dados, estima-se que o número dessas espécies possa chegar a 10.000. Nesse contexto, a presente pesquisa tem como objetivo analisar a relação entre a economia popular e solidária e as plantas alimentícias não convencionais (PANC) numa perspectiva do desenvolvimento local. Metodologicamente, adotamos a pesquisa-ação, inerente aos trabalhos orientados pelo Grupo de Estudos e Pesquisas em Economia Popular e Solidária e Desenvolvimento Local (GEPOSDEL), base dos trabalhos da Incubadora de Iniciativas de Economia Popular e Solidária da UEFS (IEPS-UEFS), articulada à disciplina Comercialização e Economia Solidária. Como resultados da pesquisa, inferimos que as PANC se consubstanciam como um dos principais elementos endógenos promissores do desenvolvimento local, elemento fundamental de uma outra economia, uma economia plural e protagonizada por pessoas, a economia popular e solidária.   Abstract The popular and solidary economy goes against the overexploitation of work and the exploitation of natural resources carried out in a predatory way as it has been historically happening. This economy, however, seeks to promote local development and socioeconomic growth in harmony with nature preservation. The human diet is restricted to about 110 plant species. Meanwhile, many ruderal species, also considered invasive or pests have an ecological importance, as well as nutritional potential, which has already been proven through scientific studies. Despite the limited circulation of these data, it is estimated that the number of these species may reach 10,000. In this way, this research aims to analyze the relationship between the popular and solidary economy and non-conventional food plants (PANC) in a perspective of local development. To do so, we applied the action research methodology, essential to the work guided by the Group of Studies and Research in Solidary and Popular Economy and Local Development.  (GEPOSDEL), which articulated to the discipline of Commercialization and Solidarity Economy, is the bases for the Popular and Solidarity Economy Initiatives Incubator of UEFS (IEPS-UEFS). As a result of the research, we infer that the PANCs are consubstantiated as one of the main promising endogenous elements of local development, a fundamental element of another economy, a plural economy and protagonized by people, the popular and solidary economy. Keywords: Popular and Solidarity Economy, Agriculture, Local development.
