In the camu camu (Myrciaria dubia) processing, the peels and seeds are the main residues with a high potential for use as they contain anthocyanins (peel) and phenolic compounds. The objective of this research was to take advantage of camu camu peels and seeds as ingredients for infusion filters, and to evaluate the effect of drying. First, the peels and seeds were dehydrated at three temperatures (50, 65 and 70°C) and characterized in total anthocyanins and total phenolic compounds. Then, they were sieved considering two size ranges: small (between 0.1 and 0.475 cm) and large (larger than 0.475 cm) to be evaluated sensorially by a trained panel as an infusion, using a hedonic scale of general acceptability of 10 cm. The results showed that the peels contain anthocyanins and a higher content of phenolic compounds. In the case of the sensory evaluation, the panel preferred the large-rang...

Human being throughout the historical evolution has been shaped as a social being par excellence. From its earliest stages could not break away from his fellows and as efficiently evolve to the present. lnstead, he had to be around your group how ensured its survival and improved their progress. This natural source development has made the need to interrelate become a basic factor of lite in groups and events which becomes increasingly efficient as the social context over time acquires greater complexity while no longer enough to stop the acquisition of skills inherent to the simple everyday bustle. Currently let this happen is to give way to indifference and chaos. Social skills training is therefore prevent serious personal and social futures (Monjas, 1997). lt involves learning and practice of promoting values such as solidarity, peace, tolerance, dialogue, justice, individual and soc...

Peasant agriculture and its agrobiodiversity systems are at a juncture in which two global processes impose significant challenges for their sustainability: climate change and the expansion of agricultural biotechnology supported by a regimen of intellectual property rights over plant genetic resources. In this article, I explore some potential risks these global processes impose on peasant agriculture, particularly on their seed systems. We analyze how, in response, peasant communities have increasingly mobilized around two converging political agendas, seed sovereignty and climate justice. In addition to the political achievements confronting some of the great biotechnology and corporate developments in the context of climate change, community peasant actions implemented to protect and defend their seeds directly contribute to reaffirming peasant seeds as part of peoples’ commons and...

The objective of the present study was to evaluate the extraction and microencapsulation of antioxidant compounds from Oenocarpus bataua Mart seed, commonly known as “ungurahui” or “patawa”. The extraction process was performed in an ultrasonic bath and the orthogonal composite central design of the response surface methodology (RSM) was used to determine the optimal extraction conditions, using two factors: ethanol concentration (48.44 to 91.56%) and extraction time (13.83 to 46.17 min). The optimal extraction conditions (48.44% ethanol and 13.83 min) allowed to obtain the extract (EUL) with the highest number of antioxidants (yield (YI): 24.64%, total phenolic content (TPC): 452.76 mg GAE/g EUL and DPPH: 74.26%). Microencapsulation of EUL with maltodextrin by spray drying produced microcapsules (EUM) of homogeneous size (5 µm), without cracks or fissures and that preserved its...

The absence of a methodology to analyze the micoflora in amaranth's seed, has motivated the performing of the present work. Seeds of two cultivars were sown (with and without disinfection process before sowing) on Petri dishes, some with "Blotter test" paper and others with five agarized culture media. All of them were placed in a chamber with 26 ºC± 2 and 16 h of photoperiod, and were incubated during seven days. After this period of time, the maximum number of different fungi genera developed on each substrate was registered, and the seed germination percentage was calculated. A total of fourteen genera of fungi (field and storage ones) were found, being Alternaria the most frequently isolated. In relation to the maximum number of fungi genera found, significant differences among the media analyzed (p>0,001) were detected, resulting the media APG, CZ and PCA the most effective one...
