Physical and chemical properties of granulated cane sugar "panelas"

Abstract

"Panela" is a natural sweetener obtained by concentrating sugar cane juice and handmade in small factories. In the study carried out, the physical and chemical properties of two commercial brands of artisanal granulated panelas and of one made on an experimental level were determined. Three lots of each sample were analyzed. The parameters measured were moisture, a w, protein, ash, minerals, reducing sugars, sucrose, pH, color (L, a and b), insoluble solids (IS), transmittance a 720 nm and filterability. In addition, a qualitative test to detect sulphur dioxide was performed. The parameters with higher variability were moisture (1.66-4.36 g.100 g-1), a w (0.51-0.69), reducing sugars (4.58-11.48 g.100 g-1), pH (5.58-6.90), and color. Potassium was the most abundant mineral (229.52-1027.18 mg.100 g-1). An inverse relationship between IS and transmittance at 720 nm (R² = 0.96) and a direct relationship between IS and ash (R² = 0.94) were found. The sulphur dioxide test was negative for all the samples.

Effect of semolina-jaggery diet on survival and development ofDrosophila melanogaster

“…Most pharmacological, gerontological, and demographic investigations require an abundance of flies for individual treatment. [10][11][12][13][14] Thus, the maintenance of a bulk population of flies in such studies is of prime significance.…”

“…18 Production of jaggery is vastly spread, with a world annual production of 11.05 million tons. 10 Moreover, jaggery has been shown to possess various medicinal properties that include antioxidant, anti-oxygenic, and anti-carcinogenic. 10,19,20 Prices range from approximately $0.25 to $1.00 per kilogram for semolina and $1.00 to $3.00 per kilogram of jaggery, thereby making them an cost-effective choice.…”

Besides, quick and hassle free preparation of semolina-jaggery (SJ) diet might prompt students and novice fly-handlers, along with professional investigators, to use the SJ diet with ease.…”

Elaboração e caracterização de doce de coco adicionado de diferentes concentrações de rapadura

“…Em geral, as rapaduras são quase inteiramente compostas de açúcares (sacarose, principalmente), e de uma pequena quantidade de outros componentes (água, cinzas, proteínas e sólidos insolúveis). Além disso, a presença de um importante grupo de minerais (K, Ca, P, Mg, Na, Fe, Mn, Zn e Cu) foi comprovada, o que aumenta os benefícios nutricionais da rapadura (GUERRA & MUJICA, 2010).…”

“…Devido à sua elevada proporção de sacarose e as vantagens já mencionadas, ele pode ser usado da mesma forma como o açúcar (bebidas, sobremesas e preparações doce) (GUERRA & MUJICA, 2010). A utilização da rapadura em doces de frutas é uma prática pouco explorada pelos pesquisadores, com isso visando utilizar esse produto típico da região nordeste na confecção de novos produtos, esse trabalho teve como objetivos elaborar três formulações de doce de coco utilizando diferentes concentrações de rapadura, para com isso avaliar a qualidade microbiológica e sensorial desses doces.…”
