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...

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 fruit seeds, commonly regarded as waste after consuming the fresh pulp, emerge as a source of unconventional starch with innovative potential. This study focuses on highlighting the significance of these seeds by exploring chemical modification methods in this starch source that add value by transforming their properties. The review emphasizes the influence of key factors such as the type of chemical reagent, its concentration, reaction parameters (pH, temperature, time), and the botanical source of the seed on the degree of modification and the resulting morphological and functional properties of the starch. The importance of specific conditioning during the chemical modification process is underscored, as it significantly contributes to enhancing the properties of the modified starch derived from fruit seed. In this regard, new perspectives are opened to efficiently harness fruit s...

The protein digestibility of pajuro seeds (Erythrina edulis Triana) was determined after the conventional cooking process. The processed seeds were dried, ground and incorporated into isoproteic and isocaloric diets for evaluation with Holtzman rats. The results were expressed in terms of means and standard deviations. A one-way analysis of variance (ANOVA) was performed with Tukey's multiple comparison test to determine significant differences (p <0.05) in the proximal composition values and a correlation analysis between protein consumption / gains weight and feed intake / weight gain. A protein value of 20.58 was obtained in the cooked straw seeds, and values of 25.89, 2.97 and 45.56 for feed consumption, weight gain and specific growth rate respectively. Regarding the protein quality indicators, a positive nitrogen balance was obtained with a value of 0.19, biological ...

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...

Today, 70% of the food supply comes from just three grains (corn, wheat and rice) but we rely on few grains. The search for the use of agro-industrial residues in industrial processing has led to obtaining unconventional products that constitute raw materials for human food. The objective of the work was to enrich baked cookies with the addition bran from seed husk of Moringa oleifera. The bran was obtained from the shell of Moringa seeds during the shelling process, which was washed, dried and ground. The bran was added in doses of 5, 10 and 15% to the formulation of the baked cookies. Microbiological analysis was carried out, physicochemical characterization by near-infrared spectroscopy, and sensory evaluation were performed on 109 untrained consumers, using a seven-point hedonic test. The microbiological analysis was satisfactory, while the proximal analysis of the bran showed a perc...
