Effects of different emulsifiers and refining time on rheological and textural characteristics of compound chocolate
The purpose of this study was to investigate the possibility of producing reduced fat dark compound chocolate in the ball mill refiner and using some selected emulsifiers. The effects of selected emulsifiers including lecithin, Polyglycerol polyricinoleate (PGPR) and citrem in two levels and two refining times on the characteristics such as moisture, particle size, hardness and rheological properties of the samples was examined. Data analysis revealed that the Casson model was appropriate to describe the rheological behavior of the samples containing lecithin and citrem; however, Power law model was appropriate for the samples containing PGPR. The results showed that citrem is the most effe…
REMOVAL OF BITTER COMPOUNDS FROM CITRUS BYPRODUCTS
Bitter compounds such as limonoids, which consist of oxygenated triterpenoid compounds, are present in citrus fruits. Removal of limonoids from citrus fruits is of considerable importance for the citrus industry. Researchers have removed limonoids from citrus fruits and citrus byproducts using organic solvents. The objective of this study was to use a simpler method to remove limonoids from citrus byproducts.
Myosin heavy chain isoforms, fatty acid composition, sensory evaluation and quality of cinta senese pig meat
The aims of this study were to examine the effects of myosin heavy chain (MHC) isoforms on Cinta Senese meat and sensory quality. The research was carried out on 65 pigs and muscle samples characteristics such as MHC isoform, meat quality, fatty acid composition, and sensory were evaluated. The results demonstrated that MHC slow isoform content was significantly correlated with pH24h (r=0.25, P<0.05) and drip loss (r=-0.31, P<0.005), whereas the content of MHC isoforms was only weakly correlated with fatty acids. Sensory evaluation was done by a trained panel test and the results shown that the MHC fast/slow ratio was correlated with the juiciness (r=-0.32, P<0.005), off-flavor (r=0.33, P<0…
Variation in meat quality characteristics between Landrace and Sicilian pigs
This study compared the meat quality of Sicilian and Landrace pigs breeds and supported these results with biochemical and histological measurements on the samples collected from the m. Longissimus Dorsi, at the level of the 8th thoracic vertebra, before electrical stimulation. Twenty clinically healthy swine, 10 male (5 for each pig breed) and 10 female (5 for each pig breed), were slaughtered at 1 year of age at a body mass of 135±10 kg and 150±10 respectively for Sicilian and Landrace pigs. Particularly on the muscle considered the morphometric characteristics of FG (fast glycolytic), FOG (fast oxidative glycolytic) and SO (slow oxidative) fibre types and their percentage were determined…
Effect of natural sea salt on physicochemical and textural properties of low sodium durum wheat bread
Today, the dietary salt intake is considerably higher than the recommendations of the EFSA for good health (3-4 g salt/day). Several initiatives have been undertaken for a reduction in salt intake. The traditional use of sodium chioride (NaCI) fulfils various important rheological, technological and sensory properties in manufacturing of baked goods. However, using NaCI in the production of food has been controversially discussed since a high intake of sodium is associated with hypertension (1). Recently, the Reg (EU) 1924/2006 on nutrition and health claims made on foods makes it possible to claims on a label 'low sodium/salt', 'very low sodium/salt' and 'sodium free or salt free' for food…
Anthocyanin profile and antioxidant activity of freshly squeezed pomegranate (Punica Granatum L.) Juices of sicilian and Spanish provenances
Pomegranate (Punica granatum L., Punicaceae) fruit is traditionally consumed in several countries, especially in Middle East, and has gained increasing popularity all over the world due to its assumed health benefits. Juices derived from the arils of the seeds were shown to be rich in anthocyanin glucosides, typically composed of cyanidin, delphinidin, and pelargonidin. The aim of the present study was the characterization of diverse Sicilian and Spanish pomegranate accessions regarding their anthocyanin and total polyphenol contents using the Folin-Ciocalteu reagent. The anthocyanin profiles were determined by HPLC-DAD and LC-MS, and color parameters were characterized using the CIELAB coo…
