Expressive Activity

The acai palm tree is a species of multiple use and of great importance for the Amazonian economy and riverside families. The high appreciation of the acai berry in the national and international markets contributes to the search for new producing areas and the reduction of repressed demand. This research aimed to identify the knowledge of the riverside families about the acai berry extraction activity in the Araguari river valley. The study was between the municipalities of Ferreira Gomes and Cutias, in an extension of 80 kilometers. The properties were sampled according to the following criteria: i) presence of natural acai massifs; ii) acceptance of the research by the interviewee and iii) permission to implement sample plots. Data were obtained through a form and interviews with structured questions. Non-probabilistic sampling (n = 13) was used to select local extractivists who hold acai areas. The field research with extractivists allowed us to infer that the period of high fruit production extends from March to June. The use of byproducts of the acai is little expressive. Although livestock is the most expressive activity in the region, others stand out: fishing, agriculture and extractivism. The commercial production of acai fruit is destined to the municipality of Cutias and most native acai owners have significant interest in the management of this species.

Abstract: The objective of this work was to estimate genetic parameters of traits at the juvenile stage of different assai palm (Euterpe oleracea) tree progenies, as well as to select among and within the most promising for fruit production. A total of 34 half-sib and 16 full-sib progenies were evaluated in a completely randomized design with eight replicates and one plant per plot. Nine traits were measured in five harvests, and the data were analyzed using the mixed model approach. The genetic variance was significant for most of the traits. Progeny-mean heritabilities showed moderate magnitudes, ranging from 51% for number of dead leaves to 59% for leaf sheath length. In general, the genetic correlations were positive and had magnitudes varying from moderate to very high. The genetic gains were more expressive for the traits plant height, leaf sheath length, and girth circumference. The full-sib progenies P33, P37, and P42 are promising for fruit production.

Açaí palm (Euterpe oleracea Mart.) is a native palm tree from the Eastern Amazon, Brazil. It is considered an economically viable source of anthocyanins for the dye and medicine industries. This study aimed to estimate the phenotypic variability and to select genotypes for genetic improvement. Descriptive statistics were used to estimate phenotypic variability. Truncated selection was performed for fruit production per bunch. The collected samples presented the highest fruit yield per cluster of all studied region. Number of fruits per cluster and stem circumference are possibly controlled by few genes. longitudinal fruit diameter may have recessive genes that are decreasing fruit size. Fruit weight, seed weight, pulp weight, number of stem per plant, total cluster length, fruit weight per cluster and pulp yield per fruit presented frequency distribution in favor of heterozygotes. There some characteristics controlled by few genes, with evidence of selection and spontaneous domestication of the matrices.

The aim of the study was to examine the changes in production and export of raspberries and sour cherries, which are the domain of Polish production on the international markets, in the countries of Eastern and Southern Europe during the 2006-2017. There was used data from Faostat database for the analysis of fruit production, and from Comtrade database for the analysis of export volume. Study points to the development of production and an increase in the export of raspberries in countries with a smaller area of cultivation of this fruit crops and stability in countries with a large area of crops of raspberries. In the case of sour cherries, in most countries, both large and small area plantings, production potential, and volume of production of fruit of this species declined. The export of sour cherries increased particularly from countries with less potential in the production of sour cherries. The development of the production and export of raspberries from countries with lower production capacity may in the future be competition for Poland on the international markets.

Abstract Although the consumption of açaí (Euterpe oleracea) pulp has long been an important component of the diet of the peoples from the Amazon, the açaí palm tree has recently attracted economic and scientific interest because of its vast array of bioactive compounds found in the fruit pericarp. The açaí seeds are the largest byproduct after pulp extraction and have potential for use in ethanol production, but this process is hindered by limited knowledge of seed biology, chemical composition and pattern reserve deposition during seed development. The aim of this work was to describe the morphoanatomical development of the seeds, as well as to identify the main organic compounds stored in the seeds. To achieve this goal, histological and histochemical analyses were performed on developing seeds. Results showed the seed is albuminous, bitegmic and that ingrowths of the seed coat give rise to a ruminate endosperm. Moreover, the nutritive reserves of açaí seeds are found in the endosperm thickened cell walls as reserve polysaccharides. Our findings provide information for future studies dealing with reproductive biology, propagation and the improvement of this profitable crop.

Originating from the palm Euterpe oleracea, the açaí is an endemic fruit of the Amazon rainforest, the consumption of which has grown strongly in Brazil since the 1990s and is emerging in other regions of the world. Consumed mainly in the form of pulp and erected as a "superfruit" by marketing players for its antioxidant and nutritional potential, the açaí berry goes through a dynamic process encompassing both its space production and international distribution circuit as well as its composition derivative products. In this conjuncture, our main objective is to understand the metamorphosis of the acai, that is to say when it is perceived much more as an economic resource than as a natural resource. To achieve this objective, our research uses as a main basis the Globalization Model of Amazonian Plants, proposed and developed by Beaufort (2017).

Acai Berry

Palms (Arecaceae) are one of the most important families of useful plants, and indigenous societies have developed very distinct ways of utilizing this resource. The clonal <em>Euterpe oleracea </em>Mart. has long been used for the preparation of frothy beverages in the eastern Amazon, in particular by colonists and caboclos, but to a much lesser extent by the indigenous population. <em>Euterpe precatoria </em>Mart., which grows in the western Amazon, is traditionally reported as resource for construction and thatch, but not as important species in alimentation. Our recent work indicates that the use of both species has dramatically shifted in the recent past. Prices for <em>Euterpe </em>products have increased dramatically due to the global commodization first of palm hearts and “Açaí berry juice” as nutritional supplement. This is especially evident in western Amazonia: In Bolivia and Peru, where older indigenous informants mostly reported thatch and houseposts as regular use for <em>E. precatoria </em>and did not know <em>E. oleracea</em>. Younger informants most commonly reported to a large extent on <em>E. precatoria </em>being used for the production of palm hearts, but less for other, while the youngest informants in many cases only knew <em>E. precatoria </em>fruits as source of beverages, as commercial fruit, and as source for handicrafts, and indicated that <em>E. oleracea </em>was being introduced because the species yielded higher harvests. In addition, many mid-age and younger informants reported <em>Euterpe </em>sp. as medicinal species, a less frequently mentioned by older informants. The local mestizo population in contrast had a broader distributed knowledge with regard to “food” uses of <em>Euterpe </em>sp., and mentioned the species as source of construction material less frequently.

Abstract Objectives Anthocyanin rich foods may ameliorate postprandial glycaemia. Postprandial glycaemia is associated with Type 2 Diabetes and a risk factor for cardiovascular disease. Acai berry is high in anthocyanins and has received attention for its health benefits. However, human trials are limited. The objective of the present study was to investigate the effect of acai berry extract on postprandial glycaemia responses in healthy adults. Methods Ten healthy participants, aged 18–65 years (mean 33 ± 16), with a body mass index (BMI) of 18.5–24.9 kg/m2 (mean 22.2 ± 1.5) completed a randomized, controlled, double-blind, crossover, acute dietary intervention trial. Participants consumed either an acai-based smoothie (AS) containing 150g acai pulp or a macronutrient-matched control placebo smoothie (PS). The primary endpoint was blood glucose concentration (BGC) which was determined by a capillary sampling method at baseline and at regular intervals up to 2 hours postprandially. Results Consumption of acai resulted in lower mean BGC compared to placebo (5.38 ± 0.46mmol/l vs. 5.40 ± 0.63mmol/l), but this was not significant (p = 0.888), even after controlling for age and BMI. There was no significant difference in BGC incremental area under the curve (iAUC) for acai relative to placebo. Conclusions In this acute study on heathy adults of a wide age range, acai consumption was not associated with improvements in postprandial glycaemia. Future long-term, adequately powered intervention studies, assessing additional biomarkers of disease risk are needed to fully elucidate the benefits of acai to health. Funding Sources None.

The article presents a comparative analysis of maturity level in Industry 4.0, of Brazilian companies with German Industry, seeking to identify learning opportunities to increase competitiveness. It was used the maturity model in Industry 4.0 developed by VDMA (German Mechanical Engineering Industry Association), applied to German companies, serving as benchmark. The same model was applied to Brazilian companies, from the State of Espírito Santo, located in the most developed region of the country, but with lower industrial density, and which has great challenges to increase its participation in the national and international markets. A field research was carried out with 46 industries, which participated in workshops to understand the fundamentals and to evaluate the maturity level in Industry 4.0. The individual results were processed by the platform of VDMA, indicating the levels in six dimensions of the model and the general result on a scale of 0 to 5. The results of all companies were tabulated, allowing the comparison with the research carried out with German companies. The study showed that, on average, Brazilian companies have the same level of maturity of German companies in readiness for Industry 4.0, with grade 0.9 in a scale of 0 to 5. But, there are significant differences in compared dimensions. 5.6% of German companies are at the advanced level in Industry 4.0, especially the technology developers, while Brazilian companies studied are still at the most basic levels. Both Industries are skeptical about investments in Industry 4.0 and the level of evaluation on Strategy dimension is still low. The comparison of expectations and difficulties allowed identify essential points to support these companies to follow the way to Industry 4.0.
