Abstract The intrinsic characteristics of many tropical fruits cause high post-harvest losses and prevent their commercialization as fresh fruits. Information about composition is crucial for defining processing conditions identifying opportunities product development. However, the analytical methods generally used to quantify sugars organic acids are costly time-consuming. Simultaneous analysi...

Paper is a thin material mainly used for writing, printing and packaging. The stem fruit of two Musa species: Acuminata balbisiana (Banana stem) Paradisiaca (Plantain were expended. chips charged into digester with different percentages (5, 10 15 %) sodium hydroxide (NaOH) subjected to the impregnating temperature (60oC) 1-hour before heating 100oC 3-hour. stems pounded finely mortar pestle the...

Studies on strength delivery and related fields have so far concentrated on finding the locations in the mill where fibres are damaged and what the damages consist of. However, fibres will invariably encounter mechanical stresses along the fibreline and in this thesis a new concept is introduced; the vulnerability of fibres to mechanical treatment. It is hypothesised that fibres with different ...

A new laccase (EC 1.10.3.2) produced by Streptomyces cyaneus CECT 3335 in liquid media containing soya flour (20 g per liter) was purified to homogeneity. The physicochemical, catalytic, and spectral characteristics of this enzyme, as well as its suitability for biobleaching of eucalyptus kraft pulps, were assessed. The purified laccase had a molecular mass of 75 kDa and an isoelectric point of...

This article reports apical closure in two cases in which necrotic pulps were present and no endodontic treatment was performed prior to closure. Possible mechanisms for the occurrence are suggested.

Fruits and vegetables include high levels of bioactive compounds with health-promoting effects. Especially, peels, which are one the generaly inedible fractions fruit or vegetable, have higher amount polyphenolic than their pulps seeds, since they accumulate in peels. Purple turnip (Brassica rapa L.) is important members Brassicaceae family due to its nutritional composition. In this context, a...

Fruit mixed pulp has the objective of improving nutritional and sensorial characteristics, as well development new flavours aromas. Different methods drying (e.g., spray-drying, spouted bed drying, freeze-drying) can influence quality final product. The this study was to select method that enables production acerola-ceriguela (ACMP) with higher quality. For selection, powder pulps were evaluate...
