Background: Pectinases are pectin degrading class of enzymes including polygalacturonase (PG), polymethyl galacturonase (PMG), pectate lyase (PEL), and pectin esterase (PE) that are commonly used in processes involving the degradation of plant materials, such as speeding up the extraction of fruit juices. Objectives: A highly methylated pectin degrading bacterium from soil covered with fruit wa...

The goal of this study was to investigate the most suitable kinetic models for pectin extraction by way of ultrasound-assisted extraction (UAE) and conventional heating extraction (CHE) with acid from melon peel. The ultrasound and acidic assisted extraction were performed on powdered melon peel in three different temperatures of 40-55-70°C and 50-70-90°C, respectively. It was observed that, in...

Pectin is a component of the plant cell and can be found in the primary cell wall and the middle lamella of plant tissues. Currently, pectin is a very important raw material, especially in the food and the pharmaceutical industries. There are several ways to extract pectin from different materials and solvents. One way to synthesize pectin is from the extraction of pomelo peel and this research...

The purpose of this study was to examine the anti-oxidative activity of pectin and other polysaccharides in order to develop a cosmeceutical base having anti-oxidative effects towards retinyl palmitate (RP). The anti-oxidative stabilizing effects of pectin and other polysaccharides on RP were evaluated by DPPH assay and then the stabilizing effect of pectin on RP was examined as a function of t...

When ingested, pectin can lower serum cholesterol levels in humans. Pectin is degraded by fecal bacteria in the colon. We examined the release of methanol (MeOH) by this degradation. A 0.2% glucose (2 g/L) mixture was used as the control medium. A pure culture of pectinolytic Erwinia carotovora was the control bacterium. The chief substrates were, in set 1, 0.2% pectin (2 g/L) and, in set 2, 0....

Recent progress in the identification and characterization of pectin biosynthetic proteins and the discovery of pectin domain-containing proteoglycans are changing our view of how pectin, the most complex family of plant cell wall polysaccharides, is synthesized. The functional confirmation of four types of pectin biosynthetic glycosyltransferases, the identification of multiple putative pectin...

Orange (Citrus sinensis) and grapefruit (Citrus paradise) peels were used as a source of pectin, which was extracted under different conditions. The peels are used under two states: fresh and residual (after essential oil extraction). Organic acid (citric acid) and mineral acid (sulfuric acid) were used in the pectin extraction. The aim of this study is the evaluation the effect of extraction c...

BACKGROUND The use of thickeners is a standard therapy for decreasing episodes of regurgitation or vomiting in infants. However, it remains to be investigated whether thickener is effective for vomiting and/or chronic respiratory symptoms in children with cerebral palsy. METHODS We enrolled 18 neurologically impaired children caused by cerebral palsy, with gastroesophageal reflux disease. In ...

Pectin is commonly used as a gelling agent in the manufacture of yogurt. The objective of our study was to evaluate the impact of 4 different types of pectin that had different degrees of esterification (DE) and amidation (DA), on the physical properties of set type yogurt. The pectin samples included 2 types of low methoxyl (LM) pectin with 38% and 45% DE, one type of low methoxyl amidate (LMA...
