Drying method and temperature control are important to ensure antioxidant capacity and stability of polyphenolic compounds (Katsube et al 2009) Antioxidant activity of food samples are affected largely based on different drying treatments Silverberry fruit is an important medicinal fruit that used for reducing pain The present work was carried out to study the effect of potassium meta-bisulfite (KMS) and air drying temperature on quality of Russian olive fruit Different KMS levels (0 1 2 and 4%) and drying temperatures (45 60 and 75C) were used and some traits such as weight loss (WL) rehydration ratio (RH-R) TSS

Different temperature treatments were given for the study (35 45 55 65 and 75C) Quantification of polyphenol and catechins: Total catechins were analyzed using the modified spectrophotometric method of Swain and Hillis [6] and the total polyphenols were estimated by using the procedure of Dev Choudhary and Goswami [8]

A process for isolating polyphenolic antioxidants from purine-containing plant material comprising the steps of: (a) extracting the plant material with a hydroxylic extracting liquid preferably at low temperature (b) selectively adsorbing the extract obtained in step (a) preferably at low temperature and (c) desorbing the adsorbed material with a hydroxylic desorbing liquid preferably at

Novaković et al (2011) investigated the influence of different drying treatments (convective drying (air-drying) osmotic drying and freeze-drying) on the antioxidant activity and phenol content of raspberries The results showed the superiority of freeze-drying convective drying caused slight changes whilst osmotic dehydration caused a

The influence of different technological treatments on alk(en)ylresorcinol (AR) contents and pattern in mango peels was evaluated using peels from six different mango cultivars AR concentrations were shown to highly depend on the cultivar While high AR concentrations were observed in the analyzed monoembryonic cultivars AR contents in the polyembryonic cultivar Nam Dokmai were significantly

2019-5-25Spearmint (Mentha spicata L ) was dried using three different drying methods: oven-drying at 45 C air-drying at ambient temperature and freeze-drying The effect of the drying method on the volatile compounds and on the structural integrity and sensory characteristics of the spice was evaluated The volatile components from fresh and dried spearmint samples were isolated by simultaneous

However in peel there were significant differences between drying treatments showing the oven-dried peel a higher water loss than the freeze-dried ( Table 1 ) /PThe evaluation of the peel or seed colour enabled to distinguish the influence of the drying treatment on some quality characteristics of these dried bio-wastes when compared to
