In addressing the country's food security, it is important to ensure a stable supply of safe and high-quality food to all citizens in sufficient quantities and assortment. Environmental pollution and intensive technologies can lead to the deterioration of food quality and a less healthy lifestyle whose component is inadequate nutrition. The specified negative factors can cause the appearance of diseases, such as obesity, diabetes, ulcers, gastritis, cardiovascular, cancer and others. An alternative is the consumption of natural products. Pumpkin provides a valuable source of carotenoids that play an important role in nutrition in the form of provitamin A. Being a rich source of carotenoids, pumpkin-based food products can help prevent skin diseases, eye disorders and cancer. Incorporating β-carotene-rich ingredients in the development of food products is considered a cost-effective approach to vitamin A-related health problems. Furthermore, the antidiabetic and anticancer properties of pumpkin have generated interest in consuming this fruit and using it as a source of various bioactives for the development of valueadded and nutraceutical products.

Some of the fruits of the family Annonaceae are appreciated for their organoleptic, digestive, nutritional, dietary, medicinal, and industrial properties. Although there is information about the nutritional value of some species such as Annona muricata (soursop) and A. cherimola (cherimoya), others are noted for their medicinal properties and toxicity. However, the antioxidant and nutraceutical potential of most of them, such as that of A. purpurea (chincuya), is unknown. The objective of this research was to evaluate nutritional and nutraceutical quality (phenolic compounds, flavonoids, and ascorbic acid) of three species of Annonaceae: soursop, cherimoya and chincuya, as well as to determine the toxicity of methanolic extracts of pulp, peel, seeds, and leaves of these species through a bioassay with Artemia salina, in order to contribute to the scientific knowledge of species with nutraceutical and economic potential in Mexico. The cherimoya fruit presented the highest concentration of crude protein (1.89 %), carbohydrates (20.65 %), the highest values of minerals (Ca, P, Mg, Na, Fe and Zn), phenolic compounds (366.27 mg EAG 100 g-1 F.W.) and ascorbic acid (48.36 mg EAA 100 g-1 F.W.). ); according to Pearson's correlation, the highest antioxidant activity was associated with the content of phenolic compounds and ascorbic acid; soursop fruit was higher than the other two species in lipid (0.31 %) and flavonoid levels (10.13 mg EQ 100 g-1 F.W.). Finally, the chincuya and cherimoya seed extracts resulted extremely toxic (LC50 = 5.0 ppm), while the soursop pulp extract was classified as very toxic (LC50 = 67.5 ppm), according to the criteria reported in other investigations extremely toxic (LC50 ≤ 10 ppm) and very toxic (LC50 10 - 100 ppm) in A. salina.

This research study proposes a classification system to identify and prevent occupational accidents in fiber storage warehouses at a pulp and paper facility. The present analysis is based on variables including pedestrian circulation, bobcat, trailer trucks, access, pedestrian circulation zones, and handrails. The proposed methodology defines and trains the system by using occupational accident event data collected at the facility. Three different predicting algorithms are used: J48 decision-making trees, Naive Bayes, and Bayesian nets. The results show that the J48 decision-making tree algorithm accurately identifies possible occupational accidents 90% of the time. It is concluded that identifying variables involved in occupational accidents allows generating a C4.5 (J48) decision-making tree that can be used as a support tool to prevent occupational accidents.

Palms have a wide distribution in tropical and subtropical regions, and are a promising source of substances for different uses. In Cuba they have been little studied and the Syagrus romanzoffiana palm is used as an ornamental plant for its beautiful leaves, as feathers and its rapid growth. In this work, the yields and the fatty acid content of the oils obtained from the whole fruits, seeds and pulps of the S. romanzoffiana palm were determined. The collected fruits were disinfected, dried and in half the seed was separated from the rest of the fruit (pulp). Whole fruits, seeds and pulps were ground separately to particle sizes <2.36 mm and the oils were obtained by extraction in Soxhlet with hexane. The oil with the highest yield (42%) and total fatty acid content (86% determined by Gas Chromatography) was obtained from the seeds. In all three oils there was a higher proportion of saturated fatty acids than unsaturated fatty acids. The highest percentages of saturated (70.5%) and unsaturated (41.3%) fatty acids in seed and pulp oils, respectively, were obtained. Lauric, oleic, myristic and palmitic acids were among the majority and arachidic, palmitoleic and linolenic acids were found among minorities. The present work allowed to know the extraction yields and the fatty acid contents of the oils obtained from the complete fruits, seeds and pulps of the S. romanzoffiana palm collected in Cuba. Such knowledge could encourage the cultivation of this palm as a possible source of oi ls for industrial use such as biodiesel or for human consumption, among others. [ABSTRACT FROM AUTHOR]

The municipality of Aranzazu (Caldas) is a producer of Andean blackberry (Rubus glaucus Benth). Its trade is scarce and low price, as well as the income for producers especially at post-harvest time when high losses are presented. In this scenario, the industrialization of the surplus in a native product was proposed, making use of both, the traditional knowledge of producers and the technical knowledge of the Faculty of Engineering at Universidad de Caldas. A posttest experimental design and control group was carried out to manipulate pulp concentration in the must pulp. The process was standardized by using 5 and 6 maturity stage Andean blackberry, and soluble solids 8.0 ° Brix, 2.93% acidity as well as percentage of citric acid were determined. Must pulp was formulated with pulp percentages from 25% to 60%, with 28 ° Brix by adding sucrose and inverted syrup, and pH 3.5 by addition of citric acid. The fermentation was carried to completion of the anaerobic for 20 weeks. The assessment of the liquor showed that liqueurs with 25% pulp have the highest concentration of alcohol with 14.5% in volume and 35% pulp obtaining the best sensory characteristics and greater acceptance.

The mango is one of the most important fruit from the commercial point of view because to its excellent sensory characteristics can get a number of products, including pulp. The aim of this work was to study the action of pectinase on stabilizing the common mango pulp. In this work yielded a product homogenized of fresh mango from a liquefied raw flesh and filter through a grid of 100 µm pore size. This homogenized was characterized and compared with the measured values of a pulp commercial fruit and commercial nectar. Then proceeded to perform commercial pectinase enzyme treatment to reduce the viscosity of the homogenized by varying the enzyme concentration, time and temperature treatment. Data were processed using response surface methodology supported by software STATGRAPHICS CENTURION XVI. The initial pulp contained a viscosity of 2.419, 4 ± 48.4 mPa* sec and the commercial pulp and Nectar 477,6 and 54,0 MPA* sec respectively. The results shows that the homogenized needs a treatment to 35°C for 90 minutes with pectinase 0.1% to obtain commercial pulp viscosity, and needs a treatment to 30°C during 85.5 min. with pectinase 0,1% to obtain a homogenized similar to a commercial nectar.

Samples of intact borojo pulp were analyzed. These samples are coming from Los Ríos Province (Ecuador), the amount of pulp obtained was 82.3% respecting the whole fruit. The pulp presents a low pH and an important level of carbohydrates and calcium. The borojo pulp obtained was microbiological high quality, with microorganism counts inside the ranges normatively allowed. Rheological behavior is characterized by oscillatory and flow tests at different temperatures. The results showed that the borojo pulp behaves as a non-Newtonian pseudoplastic fluid, where the viscosity has a more elastic behavior than viscous similar to a gel. The results of the tests oscillatory and flow shows that temperature influenced on rheological behavior of borojo pulp. [ABSTRACT FROM AUTHOR]

Cattle produced in the Colombian Caribbean during the dry season have lost weight because of the scarcity of food rich in protein and carbohydrates. To help in the solution, the pulp silage of totumo was evaluated as an alternatively in animal feeding. Drying techniques to reduce the concentration of hydrocyanic acid of the pulp were used. The study was conducted at the Center for Research and Development of Engineering Popular University of Cesar, Valledupar, Colombia. The pulp was evaluated in two stages of maturity (green and ripe), silaged during four and eight days, crushed, sun-dried and baked. A completely randomized design with six treatments and three replications was used. Manual methods were used for pulping. For physicochemical analysis of the pulp, titulation, refractometry, potentiometry, flame photometry, drying flask and enzymatic hydrolysis techniques were used. Pulp yields in mature and green totumo were 57.87% and 59.63% respectively. Totumo pulp ripe silage during four days, crushed and dried in the sun, threw a higher percentage of carbohydrates with 42.71, and the green calabash, crushed, without silage and without drying, was lower with 5.44. From a nutritional standpoint and HCN hydrocyanic acid content, the pulp of ripe calabash, with eight days of silage, crushed and dried in the oven is considered to be the most suitable for cattle feed.

Tropical fruits such as cape gooseberry, provide appreciable amounts of body carbohydrates, minerals and vitamins required for good health. Its consumption is usually as fresh fruit. Because of its high water content it is highly perishable and require conservation techniques to avoid the decrease of the organoleptic properties. Within these techniques the most appreciated is the low temperatures concentration. With this work, the physic-chemical characterization of fruit, pulp and concentrate was done in order to select the most suitable for juice production. The concentrate was obtained at low temperatures as 10°C, and physic-chemical properties were evaluated at different time intervals. The results showed no statistically significant difference between the fruit and pulp in the aw °Brix and acidity, the concentrated presented significant decreases in aw and xw and increased °Brix and acidity. The maximum concentration (30°Brix) of the pulp was reached at 6 days, with a viscosity of 13,4 mRa.s and 34,4°Brix. According to the obtained values, the cape gooseberry pulp was selected as most appropriate product for juice processing due to the better preservation of fresh fruit characteristics.
