enzymatic deinking of xerox printed papers by commercial cellulase from aspergillus niger fungi was investigated. enzymatic treatment was done under constant condition of 0.1 percent enzyme based on oven-dried weight of pulp (102 unit per 100 gram oven-dried pulp), 15 min. treatment time, in four ph levels as 4, 5.7, 8 and 9. then, the effect of ph variation on the appearance and strength prope...

The purpose of this study was to determine the dietary effects fruit pulps (dried tomato, apple and grape) on performance egg quality characteristics laying hens. In trial, 196 Lohmann sandy layers 25 weeks age were distributed into four groups with seven replicates for 9 weeks. Trial fed following diets, control group basal diet (no additive), 4 % dried tomato pulp, 4% pulp 2.5% grape pulp. Fe...

Drying is commonly used for preservation and processing of litchi. However, its polysaccharide structure may be altered by the drying process, resulting in biological activity changes. Polysaccharides from fresh and dried litchi pulp (denoted as LPF and LPD, respectively) were isolated, investigated by GC-MS, GPC and UV/IR spectrum analysis and their antitumor and immunomodulatory activities we...

The pulp of pitanga (Eugenia uniflora L.) is used to prepare pitanga juice. However, there are no reports on the identification and quantification of the main constituents in pitanga pulp. The aim of this study was to identify and quantify the major volatile and non-volatile low-molecular-weight constituents of the pulp. Isolation of volatile compounds was performed by solvent-assisted flavor e...

The influence of operating variables [viz: temperature 55-85°C, process time 30-120 min, pH 9-11,peraceticacid concentration 0.5-3.5% oven dried pulp (o.d.p.)., and sodium perborate concentration 1-5% o.d.p.] on the bleached pulp characteristics [viz: viscosity (VI), brightness (BR), kappa number (KN)], and resulting paper sheets properties [viz: breaking length (BL), stretch (ST), tear (TI), a...

The present experiment was carried out to determine the digestion kinetics of carbohydrate fractions of citrus by-products. Grapefruit pulp (GP), lemon pulp (LE), lime pulp (LI) and orange pulp (OP) were the test feed. Digestion kinetic of whole citrus by-products and neutral detergent fiber (NDF) fraction and acid detergent fiber (ADF) fractions of citrus by-products were measured using the in...

Food processing by-products are commonly used as feed ingredients for livestock. Wet tomato pulp is byproduct containing tomato seeds and skin residues and obtained during processing of tomatoes for paste, juice, ketchup etc. Tomato production in Turkey was around 10 million tons and approximately 3 million tons tomatoes were used for processing of tomatoes in 2010 [48]. During production of to...

The potential of extracellular alkali stable and thermo tolerant xylanase produced by Bacilluspumilus SV-85S through solid state fermentation was investigated in pulp bleaching in association with conventional bleaching using chlorine and chlorine dioxide. The biobleaching of kraft pulp with xylanase was the most effective at an enzyme dose of 10 IU/g oven dried pulp, pH 9.0 and 120 min incubat...

Two trials were conducted to evaluate the effects of corn or dried beet pulp on intake and digestibility of forage by lambs and on IVDMD. In Trial 1, 16 lambs (average BW = 41 +/- .9 kg) were used in a randomized complete block design with eight lambs per block. Lambs were fed a crested wheatgrass hay (7.5% CP) and received either no supplement (NS), a protein supplement (PS), or protein supple...

BACKGROUND Commercial available skin prick test with fruits can be negative in sensitized or allergic patients due to a reduction in biological activity during the manufacturing process. Prick-prick tests with fresh foods are often preferred, but they are a non-standardized procedure. The usefulness of freeze-dried extracts of Canary Islands tomatoes, comparing the wheal sizes induced by prick ...
