1. Differential gene expression of pectin esterase and changes in pectin during development and ripening stages of fruit in selected cultivars of banana
Abstract Pectin is a very important ingredient in food processing. The present study was designed to find out the changes taken place in pectin content during development and ripening phases of banana fruit. The expression of gene (pectin esterase) was also observed during development and ripening. Five exotic cultivars namely William, Brazilian, G-Naine, Ba

2. Effects of pectin and tomato paste as a natural antioxidant on inhibition of lipid oxidation and production of functional chicken breast sausage
Abstract In this study antioxidant effects of pectin and tomato paste (TP) on lipid oxidation and production of functional chicken breast sausage during refrigerated storage for 14 days were evaluated. Raw chicken sausage samples were enriched with different levels of TP containing 0, 1, 2 and 10% and 1% pectin, and peroxide value (PV), thiobarbituric acid r

3. Design, Synthesis, and Application of Colored Cobalt Pigments (Pink, Blue, Green)
The combination of white or colorless oxides (MgO, Al2O3, ZnO) with colorant ions (Co2+) generates colored pigments (pink, blue, green). The color is caused by the insertion of the colorant ion in the respective crystal lattices (periclase, alumina, wurtzite), as verified by X-ray diffraction. Absorption spectra in the visible region show analogous triplet b

4. The influence of pasteurization and starter culture on methanol content and bio-profile of fermented Morinda citrifolia Linn. (Noni) fruit juice
Abstract Morinda citrifolia L., generally known as noni, is commonly used in Thai medicines and cuisine. Several bioactive phytochemicals have been isolated and identified from the noni plant, and their compositions differ based on the cultivars and harvesting period. Different types of fermented noni fruit juices (FNJ) were used as health supplement in seve

5. Kinetic characterization, thermal and pH inactivation study of peroxidase and pectin methylesterase from tomato (Solanum betaceum)
Abstract Peroxidase (POD) and pectin methylesterase (PME) from tomato were characterized, studied thermal stability, and analyzed the synergistic effect of temperature and pH. For POD, the optimal activity, using H2O2 as substrate and ABTS+• as the donor H+, was obtained at pH 3.5, and for PME, the optimal activity using pectin as substrate was obtained at

6. Dry fruit as source of fungal contaminants or functional compounds?
Abstract This study evaluated the role of dry fruits as a source of fungal contaminants or functional compounds. Dry apple, apricot, candied fruits, prune, and white and black raisin were evaluated regarding patulin and ergosterol content, centesimal composition, pH, acidity, pectin, and phenolic profile. The ergosterol was detected in 38% of the samples and

7. Determination of active compounds in raspberry leaf extracts and the effects of extract intake on mice
Abstract Twelve typical polyphenols in raspberry leaf powder (RLP), raspberry leaf extract 1 (RLE) and raspberry leaf extract 2 (RLE-H) were analyzed by HPLC-MS. The sum of their contents in three samples were in the following order: RLP (8.6 mg g-1) < RLE (35.0 mg g-1) < RLE-H (44.1 mg g-1). Ellagic acid and quercetin-3-O-glucuronide were the principal comp

8. Preparation and Delayed Release Study on Pancreatin Encapsulated into Alginate, Carrageenan and Pectin Hydrogels
In this study, biopolymer-based pH-sensitive hydrogels have been successfully prepared using alginate, κ-carrageenan and pectin aimed at the encapsulation of pancreatin (hydrolytic enzymes like α-amylase, lipase and protease) so as to preserve enzymatic activities. Hydrogels have been characterized by Fourier transform infrared spectroscopy (FTIR), thermog

9. exoenzymes as a pathogenicity factor for Colletotrichum gloeosporioides associated with coffee plants
RESUMO Fungos fitopatogênicos durante o processo de penetração e colonização são capazes de secretar uma variedade de enzimas, as quais os tornam capazes de infectar o tecido vivo do hospedeiro, atuando na degradação de ceras, cutícula e das paredes celulares. A capacidade de um agente patogênico em produzir ou não enzimas pode determinar o grau d
