Feijoa sellowiana O. Berg é uma frutífera nativa de grande potencial cultivo, porém no Brasil existem poucos pomares em escala comercial. Uma das dificuldades à expansão da produção está vinculada a obtenção mudas clonais pela escassez protocolos eficientes para propagação vegetativa. Assim, o presente estudo teve como objetivo avaliar eficiência do antioxidante polivinilpirrolidona (PVP) na es...

Storage of 42° Brix Pineapple and Valencia orange concentrates at 40° F. resulted in in creased gelation, clarification, and apparent pulp content, whereas pectin decreased. Total glycosides, as hesperidin, remained constant in these products during storage. The experi mental packs heated at 1and 2-fold were more stable than those heated at 3and 4fold; also all of the Valencia concentrates, con...

Background and Objectives: Supercritical fluid extraction (SFE) technique has been studied for extraction of bioactive compounds from Feijoa sellowiana leaves. Results were compared with those obtained from conventional ethanolic extraction (CE). Materials and Methods: Results: The best supercritical carbon dioxide (SC-CO2) extraction conditions was determined as 250 bar of pressure, 50 &deg...

Long exposure of UV radiation increases risk of skin diseases such as cancer and photoallergic reactions. UV-B (280-320 nm) radiation is mainly responsible for inducing the skin problems. Skin protection is a suitable method against ultraviolet radiation-induced damage. Various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they have limit...

Freeze dried probiotic pineapple lassi powder was developed using Bifidobacterium bifidum (NCDC 235). Quality aspects were determined in terms of physico-chemical parameters, vitamin composition and probiotic viability. Storage changes were monitored at 25±20 °C and -18±20 °C for one year. The reconstituted lassi has carbohydrate content of 22.2 per cent, thiamin 2 mg which meets 2/3rd of sugge...

The plants of the cerra(lo and caatinga ecological provinces of Brazil, the suggested original home of pineapple (3), have many and varied mechanisms whereby they have adapted to the frequent development of moisture stress. The pineapple planit presenits a peculiarly interestinig combination of those traits that have been l)ropose(l for xerophytic and sc!erophyllous plants (10, 15). Preferentia...
