Ultra-high pressure homogenisation (UHPH) is a recently developed technology and is still under study to evaluate its effect on different aspects of its application to food products. The aim of this research work was to evaluate the effect of UHPH treatments on quality characteristics of apple juice such as antioxidant capacity, polyphenol composition, vitamin C and provitamin A contents, in co...

in this study response surface methodology was used to optimize process conditions and to evaluate the effect of ultrasound on quality attributes (antioxidant activity, ph, total soluble solid, turbidity) and the inactivation of escherichia coli bacteria in carrot juice. independent variables in this study were temperature (25-50°c), time (20-40 min) and frequency (0-130 khz). in this study the...

Synthetic melatonin (N-acetyl-5-methoxytryptamine, MT) is popular in the US and Asian markets as a health supplement. Here, we identified a naturally occurring melatonin source in apple juice. Melatonin was present in all 18 apple cultivars tested. The highest melatonin level of the edible part of apple was detected in the apple peel. The melatonin content in 'Fuji' apple juice is comparable to...

Background: Aronia berries (chokeberries) have very high levels of health-promoting polyphenols yet cause "choking" sensations due to bitterness and astringency. We aimed to describe oral sensations and palatability of aronia juice by variations in harvest time and oral sensory phenotype. Sensory blocking combinations were tested to improve juice acceptability. Methods: Ripe aronia berries were...

Mahanarva fi mbriolata (Stål) is an important pest in Latin America and causes signifi cant reduction in sugarcane productivity. There is no information regarding the effect of this pest on the quality of cane juice used for sugar and alcohol production. This work aimed at evaluating the quality of sugarcane juice from plants attacked by spittlebugs. The experiment was arranged in a completely ...

samples were collected in sterile screw capped containers and processed within 30 minutes after the collection. Sugarcane juice was diluted 10-folds in phosphate buffered saline (pH 7.3) and bacterial count was determined by surface plating on blood agar and MacConkey agar plates. 1 For the isolation of Salmonella spp. and Shigella spp, sugarcane juice (50 mL) was inoculated into equal volumes ...
