Ciclamato de sódio em refrigerantes de baixa caloria

Sodium cyclamate contents in the widely consumed low calorie soft drinks were determined. Low calorie soft drinks made from cola, guarana, orange, lemon and grape were analyzed following the technique described by Sjörberg and Alanko (1987), with some modifications. The methodology recovery assays were carried out at three spiked levels, and the average recovery of 92.5% and 110.3% were found in cola and guarana, respectively; and the relative standard deviation was of 3.7%. The average sodium cyclamate contents ranged from 27.1 ± 1.1 (cola A) to 127.3 ± 1.5 mg.100 mL-1 (lemon B), indicating that the acceptable daily intake of the sweetener can be easily exceeded after drinking low calorie beverages. All of the analyzed low calorie soft drinks showed sodium cyclamate contents higher than those stated on the label, ranging from 12.9% (cola A) to 19.0% (lemon B). Among 18 low calorie soft drinks analyzed, only four showed the average sodium cyclamate contents in accordance with the maximum limit permitted by Brazilian legislation, that is 40 mg.100 mL-1 of beverage; and in other samples the sweetener exceeded ranging from 74.8% (orange) to 218.3% (lemon B) above of the limit permitted.

A influência da idade na percepção de dificuldade de abertura de embalagens PET para refrigerantes

Nowadays, there is an increasing demand for subjective aspects of the interface between human beings and the products and systems that surround them, whether in the workplace or at home. This study addresses the association of age and the perception of difficulty during a simulation of opening process PET bottles for soft drinks. During the activities, the subjects exerted their maximum torque forces, trying to open five different models of these packages, and then they assigned scores for perception in a scale. The results indicate that for some models, there were differences between levels of perceived difficulty between age groups.

Antioxidantes informados nos rótulos dos óleos vegetais comestíveis

The study of antioxidant has a great interest to biochemistry and medicine, due to of used in the human body as inhibitor to free radical process, which can cause premature aging and degenerative diseases. Furthermore, antioxidant is widely used in food industry that i s used to prevent food deterioration, in fats and oils (autoxidation, known as rancidity). Thereby, the survey data labels of vegetable oils such as soybean one, corn one and sunflower one, it is very important, with this survey data label was possible to verify the antioxidants used on vegetable oils and describe their chemical structure, molecular formula, lethal dose and daily dose by review. Following this review, it was possible to create a website with in formation and description of antioxidants. This database has free access to the public, in order to help the population about these chemicals compounds, and help them to choose the more beneficial food to eat
