Even though food by-products have many negative financial and environmental impacts, they contain a considerable quantity of precious bioactive compounds such as polyphenols. The recovery these from wastes could diminish their adverse effects in different aspects. For doing this, various nonthermal conventional methods are used. Since extraction may cause plenty problems, due to heat production...

Grape marc seeds contain large amounts of different polyphenolic compounds so they can be used for the recovery of these classes of compounds. A new green extraction method for the recovery of phenols from the grape seeds was developed. To provide a high quality extract sourced from natural product by using enzymes as alternative solvents and spending less energy, it is impeccable to call this ...

BACKGROUND Tea is an economic important crop with high medicinal value due to rich polyphenols content. In the present research we studied the accumulation of polyphenols of in vitro regenerated callus from anthers. OBJECTIVE Callus induction of tea anthers and in vitro accumulation of phenolic compounds from the anther-derived callus. MATERIALS AND METHODS Standardization of callus inducti...

tea might be considered as the most popular drink in iran as well as some other parts of theworld. its popularity to some extent depends on its flavor and some other constituents present in its leaves orextract. black tea samples from various agro climatic zones of northeast of iran were evaluated for the chemicalconstituents, polyphenols and metal analysis that determine the quality perception...

Tannins are natural polyphenolic compounds widely found in plants. The production of coagulants for water treatment is one their new applications. Polyphenols extraction the first step synthesizing tannin-based coagulants. Eucalyptus globulus bark (EGB), an abundant by-product pulp and paper industry, usually applied as fuel energy production, was used this work a tannin source. polyphenols fro...

Agriculture and food industries generate substantial quantities of waste material with a huge potential for bioactive ingredients to be recovered converted into high-value chemicals. Red beetroot, known its high content in betalains, natural red pigments, as well polyphenols, fiber, nitrate, is experiencing increasing demand, particular juice, which leaving behind large amounts waste. The prese...
