Diet implementation with insect meal arouses increased attention in aquaculture considering the advantages of this new protein source. The effect of Hermetia illucens meal (HI) inclusion in diets on rainbow trout physical-chemical and sensory properties was evaluated. Three diets were prepared: HI0, HI25, HI50, with 0, 25 and 50% of HI replacing fish meal, respectively. Fillet sensory profiles were described by descriptive analysis (DA) and Temporal Dominance of Sensation (TDS) methods. Cooking Loss, WB-Shear Force, proximate analysis, fatty acid composition were also determined.

Kopanisti is a Protected Designation of Origin (PDO) traditional soft Greek cheese manufactured exclusively in the Cycladic island complex. It is made from raw bovine, ovine or caprine milk or a mixture of them without the addition of any lactic acid cultures. It has a spreadable texture, an intense salty and peppery taste and a strong flavour. Although Kopanisti cheese has properties similar to those of mould-ripened cheeses, its volatile compound content has never been reported. In this study the volatile compound content and lipolysis level of ten commercial Kopanisti samples were investigated.

The aim of this experiment was to select a pool of potential red/pink natural colour candidates and evaluate their stability during ultrahigh-temperature (UHT) processing and subsequent storage and to compare their behaviour against the artificial colour erythrosine. It was hypothesised that heat processing and post-treatment storage conditions would have a negative effect on the stability of the natural colourants.

Volatile compounds play a key role in determining the sensory appreciation of vegetable oils. In this study a systematic evaluation of odorants responsible for the characteristic flavour of roasted tigernut oil was carried out.

Phenolic compound profiles of 20 honeys of different botanical origin (eucalyptus, citrus, chestnut and linden) were obtained by high-performance liquid chromatography with ultraviolet detection after solid phase extraction, in order to evaluate the effectiveness of the fingerprint method for monofloral honey discrimination.

In recent years there has been increasing consumer pressure to avoid the use of agrochemicals such as chlorine on fresh plant products for extending their shelf life. The combined use of eco-sustainable techniques may be an alternative. The effect of hot water (HW), ultraviolet-C (UV-C) light and high oxygen packaging (HO) on the overall quality of fresh-cut pomegranate arils stored under modified atmosphere packaging (MAP) for up to 14 days at 5 °C was studied.

Orange-fleshed cantaloupe melons have intense aroma and flavor but are very perishable during storage life. Fresh-cut processing enhances ethylene-mediated quality losses. Post-cutting 1-methylcyclopene (1-MCP) application to fresh-cut cantaloupe was evaluated for its effects on quality attributes, phytochemical content and aroma volatiles.

The existing protocol for the cultivation of oyster mushroom (Pleurotus florida) in polyethylene bags leads to environmental pollution amounting to 18 g of polyethylene per 450 g of mushroom, which is the average biological efficiency achieved from a bag. Thus the projected annual global pollution amounts to 2 million tones, corresponding to the production of 48 million tones. Experiments were conducted at Kerala Agricultural University, India, to formulate an oyster mushroom cultivation strategy that reduces this pollution level.

Ladybug taint (LBT) is a wine fault caused by the inadvertent incorporation of ladybeetles to the wine during the winemaking process. Harmonia axyridis, also known as the multicolored Asian lady-beetle (MALB), was the only species considered responsible for causing the taint. A second species, Coccinella septempunctata (7 Spot), has recently also been implicated. The main objectives of this study were to identify and quantify the compounds associated with ladybug taint of white and red wine from these two Coccinellidae species (Harmonia axyridis and Coccinella septempunctata), and determine the most odor-active compounds in LBT-affected wines.

Consumption of pulse crops, including field pea, is considered effective for a healthy diet. Hulls (seed coats) play an important role for protection of the cotyledon and embryo, but also as mediating positive effects on health outcomes. The biochemical attributes of field pea hulls were thus assessed to determine the occurrence of specific phytochemicals and their genotypic variability.
