“…For example, in cashew drying and the residual passion fruit fiber, it was also observed a decreasing drying rate (Pena et al, 2008;Azoubel et al, 2009). Dliveira et al (2014) have obtained a drying curve similar to that found in the present study, when evaluating the drying curve of dry Jambu, in the oven at 45 °C.…”

“…It is often used as flavoring in dishes from Northern Brazil, such as Tacacá and Pato-no-tucupi. Also, it is used in the traditional medicine to treat stomatitis, influenza and as an analgesic product (Nascimento et al, 2013). Important chemical property of the plant has aroused the interest of the pharmaceutical industry, due to the presence of the active ingredient known as spilanthol (Borges et al, 2012).…”

The aim of this study was to evaluate the microbiological and sensory quality of the Jambu (Acmella oleracea L.) in natura and dried by cold air, and the determination of its drying curve. The microbiological analysis were performed to Salmonella spp, the coagulase-positive Staphylococcus, and coliforms in the both Jambu samples, at 45 °C. Tacacá, the typical food dish of Pará state, Brazil, has showed good consumer global acceptance in the sensory evaluation of Jambu in natura (score of 8.00 ± 1.46) and dried (score of 8.67 ± 0.66). Both samples, Jambu in natura and dried by cold air, were by the current legislation regarding the microbiological aspects, this is the absence of Salmonella spp, coagulase-positive Staphylococcus <1×10 1 CFU/g, and coliforms <3 MPN/g, at 45 °C. Thus, considering sensory and health aspects, the commercialization of dried Jambu becomes viable, facilitating its transportation and handling, as well as for reducing its vegetable mass.Keywords: Jambu; Acmella oleracea; dehydration by cold air; sensory acceptability.Practical Application: Considering sensory and health aspects, the commercialization of dried Jambu becomes viable.

Centaurea cyanus L. Polysaccharides and Polyphenols Cooperation in Achieving Strong Rat Gastric Ulcer Protection

et al. 2015

This work was aimed at testing gastroprotective effects of Centaurea cyanus L. (herba) polysaccharides (P) and polyphenols (A) fractions on stress-induced rat ulcer model. Studies evaluating acute toxicity in rats and antioxidant (chemiluminescence method) and antimicrobial (on Staphylococcus aureus ATCC6538 and Escherichia coli ATCC8739 strains) activities of Centaurea cyanus L. (herba) product, which combined polysaccharides and polyphenols fractions (PA), have also been done. Accordingly, in vivo pharmacological studies revealed high influence of PA product (500 mg kg -1 of body weight) on deep, moderate and superficial gastric mucosal lesions, greater than that of chemical reference, Ranitidine. P product was proven more effective than Ranitidine in opposing the emergence of deep necrotic lesions only, suggesting the ability of polysaccharides compounds to consolidate gastric mucous layer as well as their certain tendency for cooperation with polyphenols fractions. The acute toxicity study indicated the lack of toxicity of PA product and maximum tolerated doses greater than 1875 mg kg -1 of body weight. PA product provided augmented scavenger activity and week antimicrobial activity on Staphylococcus aureus ATCC6538 and Escherichia coli ATCC8739 strains, resulting in better opportunities for valorisation of the aerial part of Centaurea cyanus L. species in order to obtain new and effective natural medicines.

“…Popularly known as "jambu", "agrião bravo" or "agrião do Pará", its leaves and flowers cause a slight tingling and numbness in the tongue (NASCIMENTO et al, 2013). The leaves and stems are widely used in the state of Pará (Northern of Brazil) in typical recipes such as the "tacacá" and "pato no tucupi" or in rice and pizzas (COSTA et al, 2013).…”
