Desenvolvimento de bebida láctea potencialmente probiótica carbonatada: características físico-químicas, microbiológicas e sensoriais

The goal of this work was to develop a strawberry fl avored dairy beverages carbonated and fermented with potential probiotic bacteria. Four formulations of dairy beverages were elaborated: Control (BL); Fermented (BLF); Carbonated (BLC) and Carbonated Fermented (BLFC). In samples submitted for carbonation, a carbonator was used for the carbon dioxide (CO2 ) gas injection dissolved in drinking water and the cultivation consisting of lactic bacteria Lactobacillus acidophilusLA-5®, Bifi dobacterium BB-12® and Streptococcus thermophilus (Biorich, Chr. Hansen) was employed on the fermented samples. The samples were characterized by physical and chemical, microbiological and sensory parameters. The BLC sample showed the presence of yeasts and coliform counts, but the counts indicated that it was suitable for consumption in 28 days time. The BL presented average coliform counts above the limit established by the law after 21 days of refrigerated storage. The presence of lactic bacteria and CO2 and their effects on lower proteolysis indexes, lower pH values and higher acidity values were correlated with signifi cant inhibitory effect of contaminated microorganisms in the BLF and BLFC. The carbonation was not stimulatory for the growth of lactic crops, mainly in the genus Bifi dobacterium spp. and Streptococcus spp. The BLF drink presented greater sensory acceptance and purchase intention test results, however the carbonated beverage presented positive results, with mean values greater than 50% in the acceptance tests with potential inclusion as sensory differential in dairy beverages. Just BLFC drink was considered potentially probiotic, by presenting minimum counts of Lactobacillus spp. during storage. Further studies should be conducted with the technology of carbonation, since it has been proven the correlation of the presence of CO2 with inhibitory effect of contaminated microorganisms and lower physical and chemical changes of dairy beverages.

José Marques de Melo e os estudos científicos da folkcomunicação

This paper aims some academic contributions of José Marques de Melo for the study and propagation of Folkcomunication Theory, developed by Luiz Beltrão, in 1967, in his PhD thesis. Marques de Melo, disciple of Beltrão, is one of the most representative names on the set of international scientific studies of communication. Divided in three parts, this text covers theoretical contributions (conception and classification of genders, formats and types of taxonomy of Folkcomunication); dialogues with other thinkers (McLuhan, Morin and Freire) and empirical contribution (internet as a Folk tool). We emphasize that the contributions of Marques de Melo are fundamentals for the new generations to understand the importance of the Folkcomunication and see it as a complex communicational system.

Efeito do Ácido Ascórbico em melões 'Orange Flesh' minimamente processados

The aim of this work was to evaluate the application of different concentrations of ascorbic acid on Orange Flesh melon. Whole Melons were sanifi ed with 500 mg L-1 of sodium hypochlorite for 10 minutes and the cuts into cubes with 100 mg L-1 for 1 minute before being tested under different concentrations of ascorbic acid (0, 1, 2 and 3%) in immersion at room temperature for 10 minutes. After drainage, the cuts were packed in PET packages lined with polyethylene fi lm of 18 µm and stored at 5 ± 1°C and 85 ± 5% of RH for 8 days, being evaluated every 2 days. Physicochemical, microbiological and sensorial analyses were performed. The experimental design utilized for the experiment was the completely randomized in factorial scheme. Ten replicates were used for non-destructive analyses and 3 replicates were used for destructive ones. The application of ascorbic acid reduced the loss of mass; the fruits presented a low population of psychrotrophic bacterias, fi lamentous, fungi and yeasts, reduction of soluble solids, pH and fi rmness and, consequently, extended postharvest life of the fruits by 2 days. The appearance, fl avor and taste were also affected. The application of 1% of ascorbic acid was the best treatment for the fresh cuts “Orange Flesh” melons.

Comprimento radicular e nutrição de cultivares de painço em resposta à calagem

Information on improved cultivars of fall panicum and cultural practices concerning its cultivation is scarce in Brazil. So, the objectives of this research work were to evaluate root length and the mineral nutrition of fall panicum plants as influenced by liming in an acidic soil. The experiment was conducted in vases containing 13 dm3 of soil under greenhouse conditions up to 44 days after seedling emergence. The experimental units were distributed inside the green house according to a completely random design in a 2 X 4 factorial scheme, that is, two fall panicum cultivars (‘AL Mogi’ and ‘AL Tibagi’) and four doses (0.0, 1.67, 2.91, and 4.15 t ha-1 ). The experimental units were replicated 4 times. ‘AL Tibagi’ plants root system showed more tolerance to soil conditions of low base saturation. That cultivar also absorbed more efficiently P, N, Ca, Mg, and K from the acidic soil. Liming brought about increments of P, N, Ca, Mg, and S absorption by the fall panicum cultivars.

Filossilicatos: efeitos no crescimento e na nutrição de plantas de milho e no teor de silício do solo

Importance of silicon fertilization is related to the benefits that silicon is able to promote tolerance to heavy metals, reduce the incidence of pests and diseases, increased productivity, drought tolerance, among others. The objective of this study was to evaluate the phyllosilicates effect on biomass formation, nutrients and silicon on the early stages of corn plants compared to wollastonite. Experiment was installed and conducted in a greenhouse located at the Universidade Estadual Paulista, UNESP, in Registro, SP. Consisting of 10 treatments established in a randomized block design in scheme factorial (2 x 5), with five replications. First factor corresponds to the two types of soil (Oxisol and Ultisol) and the second factor, five treatments (control, 0 kg ha-1 Si; wollastonite W13, 13 kg ha-1 Si; wollastonite W26, 26 kg ha-1 Si; phyllosilicates F13, 13 kg ha-1 Si; phyllosilicates F26, 26 kg ha-1 Si). In Ultisol, phyllosilicates increased production of fresh, dry biomass and silicon content in shoots of corn compared to treatment with wollastonite and control. Highest Si content compared to control (6.2 g kg-1) was obtained with 13 kg ha-1 Si of phyllosilicates (9.8 g kg-1). The greatest accumulation mass and Si in plants by applying phyllosilicates were observed in Ultisol, although this display Si content higher than Oxisol.

Efeito da calagem e adubação potássica no crescimento e nutrição da cultura da mamona (Ricinus communis L.)

The castor bean is an oilseed crop of outstanding importance in Brazil and worldwide. Besides the wide application in chemical industry, is important due to its tolerance to drought, making it a viable crop for the semi-arid region of Brazil, where there are few agricultural alternatives. However, this culture is not unique to semi-arid region and is also planted with excellent results in various regions of the country. The study aimed to evaluate the effects of liming and potassium fertilization on the crop of castor bean. The experiment was conducted in a greenhouse in a randomized complete block randomized in a factorial 3 x 2, where the first factor consisted of potassium (0, 30 and 60 kg ha-1) and in the presence or absence lime to raise the base saturation to 60%. It was found that liming in combination with an intermediate dose of K2O (30 kg ha-1) elevates the production of dry mass of the area, however not change the concentration nutrients in the castor bean.
