What is more interesting about brown adipose tissue (BAT) is its ability to provide thermogenesis, protection against obesity by clearing triglycerides, releasing batokines, and mitigating insulin resistance. White adipose tissue (WAT) on the other hand stores excess energy and secretes some endocrine factors like leptin for regulating satiety. For the last decade there has been an increasing i...

The browning kinetic was recorded using color data information from images of avocado slices. GLCM image texture was used to describe the reaction. In the experiment, images of avocado slices stored at 4°C were captured and saved in tiff format. The classical color intensity index (the mean L* value) and some statistics GLCM image textures were used. Results showed that it is possible to use GL...

A model solution of orange juice was prepared and stored. Factors affecting browning and formation of such decomposition products as 3-hydroxy-2-pyrone (3OH2P), 5-hydroxymethylfurfural (HMF), furfural, 5-hydroxymaltol, and 2-furoic acid were examined. Ascorbic acid (AsA) was essential for browning, which was stimulated by amino acids and citric acid, and repressed by chelators and radical scave...

Image analysis was applied to examine banana peel browning. The banana samples were divided into 3 treatment groups: no treatment and normal packaging (Cont); CO2 gas exchange packaging (CO); normal packaging with an ethylene generator (ET). We confirmed that the browning of banana peels developed more quickly in the CO group than the other groups based on sensory test and enzyme assay. The G (...

The recent browning (increase in color) of surface waters across much of the northern hemisphere has important implications for light climate, ecosystem functioning, and drinking water treatability. Using log-linear regressions and long-term (6-21 years) data from 112 Swedish watercourses, we identified temporal and spatial patterns in browning-related parameters [iron, absorbance, and total or...

The effectiveness of pineapple juice in enzymatic browning inhibition was evaluated on the cut surface of banana slices. After storage of banana slices at 15 degrees C for 3 days, pineapple juice showed browning inhibition to a similar extent as 8 mM ascorbic acid but less than 4 mM sodium metabisulfite. Fractionation of pineapple juice by a solid-phase C18 cartridge revealed that the directly ...

The consumers interest in gelatin authentication is high due to allergic reactions and adoption of Halal and Kosher eating cultures. This research investigated browning development due to enzymatic hydrolysis and presence of Cu2+ during Maillard reaction of fish, porcine, and bovine gelatin. The rate of browning index samples showed two phases-rapid and slow-for all the gelatin samples and chan...

Enzymatic and nonenzymatic browning reactions of amino acids and proteins with carbohydrates, oxidized lipids, and oxidized phenols cause deterioration of food during storage and processing. The loss in nutritional quality and potentially in safety is attributed to destruction of essential amino acids, decrease in digestibility, inhibition of proteolytic and glycolytic enzymes, interaction with...

Enzymatic browning of apple fruits (Malus × domestica Borkh.) is the main factor responsible for quality deterioration in processed products such as juice, fresh-cut slices and chips.The fresh slices of apple were dipped in 1% ascorbic acid solution for one min and hot water with 50°C for two min. The results showed that both heat and ascorbic acid treatments could significantly reduce cut surf...
