The development of rancidity and its effect on quality loss was studied in frozen horse mackerel (Trachurus trachurus). For that, two different kinds of fish products (whole fish and fillets) were stored at a commercial frozen temperature (-20oC) for up to 12 months and were compared to samples stored at a much low temperature (-80oC). Analyses included: lipid hydrolysis (free fatty acid format...

IT is now generally agreed that the deterioration of oils and fats, whether due to the action of air, light and moisture, or to the action of micro-organisms, is an oxidative process subsequent to partial hydrolysis. In these two forms of rancidity-that of pure fats (where the absence of nidus prevents bacterial or mould growth) and that caused by micro-organisms-the course of the oxidation is ...

INTRODUCTION Kuṅkumādi Ghṛta (KG) is an Ayurvedic formulation commonly recommended in skin disorders, especially Mukhadūṣikā (Acne vulgaris). Kesara (stigma of Crocus sativus Linn.) is a prime ingredient in the formulation. However, due to high cost and increased adulteration in Kesara, 'Nāgakesara' (Mesua ferrea Linn.) is suggested by Ayurvedic experts as a substitute. Nāgakesara is relatively...

The main aim of this study was to evaluate the effect nut sizes and drying methods on sensory attributes hazelnut cultivars (Corylus avellana L. cvs. Çakıldak, Palaz Tombul) during storage. Shelled were dried under sun, shadow at room conditions cold 2 °C 7 stored 20±5 80±5 % relative humidity. Evaluation carried out quarterly (harvest, 3, 6, 9 months). In Çakıldak cultivar (in 16 mm size), odo...
