There is a large body of research demonstrating that macronutrient balancing is a primary driver of foraging in herbivores and omnivores, and more recently, it has been shown to occur in carnivores. However, the extent to which macronutrient selection in carnivores may be influenced by organoleptic properties (e.g. flavour/aroma) remains unknown. Here, we explore the roles of nutritional and he...

Tujuan penelitian ini adalah mengetahui tingkat penerimaan secara organoleptik dan sifat kimia sirup daun sirsak dengan penambahan sari jeruk nipis. Uji yang dilakukan uji organoleptic meliputi rasa, warna aroma menggunakan metode hedonic serta terhadap kadar abu, total gula, vitamin C rendemen. Hasil hedonik atau kesukaan pada 30 orang panelis baik dari segi aroma. Tingkta memperoleh nilai rat...

The composition of essential oils and their mixtures used to formulate gin is usually too complex to separate all sample components by standard capillary gas chromatography (GC). In particular, minor constituents that possess important organoleptic properties can be masked by co-elution with major sample components. A solution is provided that combines gas chromatography/mass spectrometry (GC/M...

Low-dose, low-penetration electron beam (E-beam) irradiation was evaluated for potential use as an antimicrobial intervention on beef carcasses during processing. The objectives of this study were (i) to assess the efficacy of E-beam irradiation to reduce concentrations of Escherichia coli O157:H7 on a large beef surface and (ii) to evaluate the effect of the treatment on the sensory properties...

Although the organoleptic method of tea testing has been traditionally used for quality monitoring, an alternative way by machine vision may be advantageous. Although, the three main quality descriptors estimate the overall quality of madetea, viz., strength, briskness and brightness of tea liquor, the exact colour detection in fermenting process leads to a good quality-monitoring tool. The use...

Winemaking is a complex process involving the interaction of different microbes. The two main groups of microorganisms involved are yeasts and bacteria. Non-Saccharomyces yeasts are present on the grape surface and also on the cellar. Although these yeasts can produce spoilage, these microorganisms could also possess many interesting technological properties which could be exploited in food pro...

Aloe Vera has gained more attention over the last decade due to its reputable, medicinal, and pharmaceutical and food properties. In present research, firstly the different concentrations of pectin and gum acacia were augmented with aloevera gel and the products so prepared were assessed for texture and stickiness. The selected preparation was then supplemented with orange flavour at different ...

It is well established that non-Saccharomyces wine yeasts, considered in the past as undesired or spoilage yeasts, can enhance the analytical composition, and aroma profile of the wine. The contribution of non-Saccharomyces yeasts, including the ability to secret enzymes and produce secondary metabolites, glycerol and ethanol, release of mannoproteins or contributions to color stability, is spe...

Ten strains of Geotrichum candidum were studied on a liquid cheese model medium for the production of sulfur compounds which contribute to the aroma of cheeses. The volatile components produced by each cultured strain were extracted by dynamic headspace extractions, separated and quantified by gas chromatography (GC), and identified by GC-mass spectrometry. It was shown that four strains of thi...

This study was carried out to study some quality indices (acid value, peroxide value and UV absorption K232nm, K270nm and ∆K) of virgin olive oil of three varieties (Coratina, Koronakii and Picual) at two stages of ripening. Also, organoleptic tests, phenolic content, αtocopherol and oxidative stability measured by Rancimat method at 100 ̊C were determined. Fatty acid composition and volatile co...
