BACKGROUND Efforts are being made to apply physicochemical parameters analysis in the identification of varietal honeys. With many variables describing a given population, it is feasible to differentiate between basing on principal component analysis (PCA). The aim of this study was to investigate selected physicochemical quality characteristics of nectar honey, with particular emphasis paid to...

BACKGROUND Tarhana, a wheat-yoghurt fermented mixture, is considered as a good source of saccharides, proteins, some vitamins and minerals. Moreover, their preparation is inexpensive and lactic acid fermentation offers benefits like product preservation, enhancement of nutritive value and sensory properties improvement. The aim of this work was to evaluate changes of some chemical parameters du...

In this study some selected chemical properties such as total soluble solids, pH, total acidity, formalin index, reduced sugar content and ascorbic acid of major sour cherry cultivated grown in different provinces of Iran corresponding were investigated.  Minerals K+, Na+, Ca2+, Mg2+, Cu2+, Fe2+ and Zn2+ were determine...

Wild-growing edible flora should be investigated to improve human food sustainability and security. Portulacaria afra (spekboom) is an undervalued succulent plant that thrives in harsh conditions Southern Africa. This study determined whether the indigenous spekboom can harnessed as a sustainable, nutritious source ingredient. Physicochemical nutritional analyses were conducted on fresh process...

Photosynthetic characteristics and induction of crassulacean acid metabolism (CAM) by drought stress were investigated in Sedum album, Sedum stoloniferum and Rosularia elymaitica from Crassulaceae. Titratable acidity, malate content, phosphoenolpyruvate carboxylase (PEPC) activity and gas exchange parameters were determined in plants at the end and beginning of the photoperiod. Results showed t...

Roselle calyces are rich in nutrient, but the utilization of its calyces in the preparation of jam is not popular in Africa. The quality attributes of stored Roselle jam from dark and light red varieties were investigated. Roselle jam was processed using the open kettle method. The processed jams were stored at ambient and cold temperatures. At two weeks interval they were evaluated for pH, tit...

Background: Pineapple juice processing is an art of preservation, and the processing technologies play important role in pineapple juice quality. Therefore, this study aimed to explore the potential impacts of non-thermal processing methods on the physicochemical, bioactive, and microbiological properties of fresh pineapple juice. Methods: Extracted juices were subjected to several non-thermal...

In recent years there has been a shift in the focus of biotechnological progress to find new approaches in food fermentation and develop multifunctional microorganisms to improve the nutritional and health benefit of food. In the present study, rice-mucuna blends of different formulation, (100:0, 100:0, 90:10, 80:20, 70:30, 60:40, and 50:50) respectively, were subjected to solid state fermentat...
