A nondestructive optical method for determining the soluble solids content of fresh whole tomatoes was investigated. The method, based upon near infrared spectrophotometric techniques, could predict the soluble solids content of tomatoes (r 5 0.92, SEC 5 0.277Brix). Tomatoes from more than 30 popular fresh market cultivars at stages of maturity from mature green to ripe red fruit were studied.

A nondestructive optical method for determining the total solids content (TSC) and soluble solids content (SSC) of fresh whole prune (Prunus domestica L. ‘French’) was investigated. The method, based upon near infrared spectrophotometric techniques, could predict the TSC (r /0. 98, SEP /0.80% FW) and SSC (r /0. 96, SEP / 1.02%) of prunes. A low cost ($250

The purpose of the study was to compare basic fruit chemical composition of four highbush blueberry cultivars: ‘Spartan’, ‘Bluecrop’, ‘Jersey’ and ‘Blueray’. The plants were grown on plantation near Szczecin in the years 2001 – 2003. Basic chemical composition of fruit including total ash, crude fibre, total nitrogen, soluble solids, titratable acidity, dry weight and total polyphenol content w...

Separation of solids from liquid swine manure and subsequent thermochemical conversion (TCC) of the solids fraction into oil is one way of reducing the waste strength and odor emission. Such processing also provides a potential means of producing renewable energy from animal wastes. Gravity settling and mechanical separation techniques, by means of a centrifuge and belt press, were used to remo...

This study investigated the effect of season (wet and dry) on milk composition of the dromedary camel (Camelus dromedarius). Milk samples representing the wet and dry seasons were analyzed for total solids (TS), fat (F), solids-non-fat (SNF), ash, crude protein (CP), nitrogen soluble at pH 4.6 (SN), mineral content (MC) and casein fraction (CnF). Camel milk had higher (P

The flow-ability of granular is important parameter to be considered in many solids handling processes and operations such as transportation and storage. Flow property of granular solids depends on many factors of the physical properties such as the particle size distribution, the roughness of its surface, the content of moisture in solids and the relative humidity and temperature in its surrou...

Refractometric analysis of total solids in serum and urine is simple, accurate, and rapid. Adolph (1) demonstrated the high coefficient of correlation between refractive index and total solids of dog plasma and subsequently employed refractometry as an index of the total solids of human serum (2). Blohm (3), using a dipping refractometer, showed for human urine that the reading given by that fl...
