| Abstract Vitamin C is imperative component of our nutrition and used as additive in many foods owing to its high antioxidant activity. The degradation of vitamin C content in orange juice during storage was evaluated in this study. Degradation of vitamin C in orange juice during 40 days storage at 0, 05, 15, 25, and 40 °C was analyzed and evaluated. Hydroxymethylfurfural (HMF) accumulation in orange juice acts as an indicator of ascorbic acid degradation. The initial vitamin C content in orange juice was 34.26 mg/100 mL that reduced when subjected to various storage conditions such as temperature and time. The loss of vitamin C during storage was lowest at 0 °C and the losses increased with rise in temperature. The Vitamin C content after 40 days in orange... |

| The objectives of this research were to determine physico-chemical characteristics of 1,758 Apis mellifera L. honey samples produced by in the productive pole of Picos, state of Piauí, to understand, based on these characteristics, how they are grouped and to determine the percentage of honey that fit the specifications determined by Brazilian legislation. Thirty-five honey samples were collected directly from beekeepers for determination of total sugars, reducing sugars, apparent sucrose, humidity, diastase activity, hydroxymethylfurfural (HMF), protein, ash, pH, acidity, formol index, electrical conductivity, viscosity and color. Mean values of each one of the analyzed physico-chemical parameters are within the limits established by the current Brazilian... |
