Rambutan (Nephelium lappaceum) peel is a potential source of antioxidant. As rambutan is a seasonal fruit, a proper heat treatment prior to storage is necessary. Thus, this study was conducted to determine the effect of water and steam blanchings on browning enzymes and antioxidant activities of rambutan peel extracts. Rambutan from the variety of ‘Anak Sekolah’ were peeled and the peel was bla...

The oranges were purchased from the local market of Bela. The orange peel and pulp were subjected to successive extraction with solvents in increasing order of their polarity viz. Acetone, hexane, methanol and distilled water. Orange peel and pulp powder was extracted separately by aqueous extraction. Phytochemical analysis indicated the presence of tannins, saponins etc. Anthraquiones were com...

Examination of the dried peel powder of Citrus kawachiensis, one of the citrus products of Ehime, Japan, showed that it contained naringin (NGIN; 44.02 ± 0.491 mg/g), narirutin (NRTN; 4.46 ± 0.0563 mg/g), auraptene (AUR; 4.07 ± 0.033 mg/g), and 3,5,6,7,8,3',4'-heptamethoxyflavone (HMF; 0.27 ± 0.0039 mg/g).

The present study aims qualitative screening of the phytochemicals present in the peel of Amorphophallus paeoniifolius (Jimikand/ Suran) for its utilization as a potential therapeutic. The peel extract was prepared by dissolving dried peel powder in solvents like water, methanol, petroleum ether, and chloroform and concentrated using a rotary vacuum evaporator. The standard qualitative test for...

The oranges were purchased from the local market of Bela. The orange peel and pulp were subjected to successive extraction with solvents in increasing order of their polarity viz. Acetone, hexane, methanol and distilled water. Orange peel and pulp powder was extracted separately by aqueous extraction. The phenolic content of these samples were studied according to the method described by Folin ...

Peel powder and juice of fresh pomegranate (Punica granatum) were utilized to prepare cookies as sources of antioxidants, along with the other common ingredients, in the present study. The components were added in different proportions during the cookie preparation and their rheological, sensory and antioxidant properties were evaluated.
