This study evaluated the presence of biogenic amines in fermented cow's and goat's milks containing probiotic bacteria, during the first 10 days of chilled storage (4 ± 2°C), when the probiotic strains are most viable. The overall acceptance of both fermented milks, produced using the same starter culture and probiotics, was tested. In both products, the initially high levels of tyramine (560 m...

Chilled (0, 2, 6, 10, 13 and 15 days) and frozen (0, 0.5, 2, 4, 8 and 12 months) sardines were used to determine the influence of such storage times of fish over the quality of the final canned product. Traditional determinations of lipid quality (free fatty acids content, thiobarbituric acid index and polyene index) were studied and compared with the formation of fluorescent compounds expresse...

In order to characterise the spoilage related to microbiota of raw salmon, a combination of culture-dependent and -independent methods, including PCR-TTGE, was used to analyse 3 raw salmon batches stored for 3 days at chilled temperature in modified atmosphere packaging (MAP) (50% CO₂/50% N₂) or under vacuum. Sensory evaluation, microbiological enumeration and chemical analysis were performed a...

Storage of jicama roots at 10 °C resulted in characteristic chill-induced changes in pulp color (decreased L* values and increased chroma) and texture (increased distance to rupture) after 7–14 days. Discoloration or browning of the pulp occurred first in exterior pulp tissue and then progressed to the interior tissue. Changes in texture during storage were similar in exterior and interior pulp...

In an effort to integrate the measurement of savings into the normal procedures of qualifying for utility incentives, New England Electric has developed stringent end-use metering requirements for the installation of all cool thermal storage systems. Payment of incentives has been made contingent upon successful demonstration of data collection capabilities. Measurements include total cooling s...

In the present research, performance validation of a Heating, Ventilation, and Air Conditioning (HVAC) system operating in a library building was conducted. The operating HVAC system was studied in terms of the provided indoor air conditions and energy consumption level. The fieldwork measurements showed that the HVAC system is not capable of providing the desired indoor air conditions based on...
