The effects of mandarin scions on peel components and juice quality parameters were investigated in this study. Peel flavor components were extracted by using cold-press and eluted by using n-hexane. Then all analyzed by GC-FID and GC-MS. Total soluble solids, total acids, pH value, ascorbic acid as well as density and ash were determined in juice obtained from mandarin scions. Twenty-seven, Tw...

Permittivities from 10 to 4500 MHz at 24◦C were measured on pulp and juice of watermelons of different maturities with an open-ended coaxial-line probe and network analyzer. The dielectric constant of both materials decreased monotonically with increasing frequency and loss factor had a minimum at about 1000 MHz. Moreover, the pulp and juice had very similar loss factor values at each frequency...

The antioxidative phytochemicals in various fruits and vegetables are widely recognized for their role in scavenging free radicals, which are involved in the etiology of many chronic diseases. Colored fruits are especially considered a quality trait that correlates with their nutritional values and health benefits. The specific aim of this study was to investigate the antioxidants in the juice ...

The clarification of mixed juice has been the subject of research for decades, due mostly to its large impact on sugar quality. Much, if not all, of the work has however been done on mixed juice originating from milling rather than from diffusion. This paper examines a back-to-basics, laboratory approach, involving cane juices produced from conditions simulating milling and diffusion. Furthermo...

With SGF Profiling™ we introduce an NMR-based screening method for the quality control of fruit juices. This method has been developed in a joint effort by Bruker BioSpin GmbH and SGF International e.V. The system is fully automated with respect to sample transfer, measurement, data analysis and reporting and is set up on an Avance 400 MHz flow-injection NMR spectrometer. For each fruit juice a...

Accepted: 21/03/2014 Abstract Enzymes are an integral component of modern fruit juice manufacturing processes. Their main functions are to: increase extraction of juice from raw material, increase processing efficiency (pressing, solid settling or removal), and generate a final product that is clear and visually attractive. Juice extraction can be done by using various mechanical processes, whi...

Codex Alimentarius defines juice as “the fermentable but unfermented juice, intended for direct consumption, obtained by the mechanical process from sound, ripe fruits, preserved exclusively by physical means. The juice must have the characteristic colour, flavour and taste typical of the fruit from which it comes, it may be turbid or clear. The juice may have been concentrated and later recons...

abstract to study the effects of different levels of n, mn and zn on yield and quality of pomegranate fruit a factorial experiment based on complete randomized block design with 18 treatments and three replications was conducted in behshahr city, mazandaran province, in 2009.investigated treatments were include: nitrogen, manganese, zinc. fertilizer source for nitrogen was urea and three rates ...

For a number of years, due to the compatability of citrus juice and milk, the citrus and dairy farmers looked for a suitable means of processing and packaging citrus juice for distribution by dairy route trucks. With the advent of chilled orange juice, this was ac complished. Cartoned, or chilled orange juice as it is commonly called, is a single strength orange juice, marketed in a waxed fiber...

The effect of nonthermal pulsed electric field (PEF) and thermal treatment (900C for 60s) was studied on quality parameters of Emblica officinalis juice for the period of 6 weeks at 40C using monopolar rectangular pulse of 1μs width. The PEF treatment was given using static chamber at 24kV/cm for 500μs. The quality of Emblica officinalis juice was investigated in terms of non enzymatic browning...
