In this study, thermal inactivation of Salmonella Enteritidis inoculated to the cake dough and a whole raw chicken was investigated. The cake dough was inoculated with 6.15 log-cfu/g S. Enteritidis then, thermal treatment was applied at 160°C top-bottom fan cooking mode. The initial count of S. Enteritidis showed reductions 1.49 log-cfu/g, 2.06 log-cfu/g and 4.29 log-cfu/g in the samples from the cold point location from the geometric center of the cake at 5, 7 and 10 minutes of thermal treatment, respectively. Although S. Enteritidis is not detected at the end of 15 minutes of heat treatment, the center of the cake temperature has reached 85.69°C and the cake sample is uncooked and its sensory properties are not acceptable. The cake that is safe and favorable with the sensory properties to the consumers was obtained by heat treatment for 30 minutes. After the cold point of a whole raw chicken was inoculated with 7.29 log-cfu/g S. Enteritidis, thermal treatment was applied at 220°C top-bottom fan cooking mode. The temperature at the cold point of 35 and 45 minutes heat-treated chickens reached 59.33 and 74.08°C, respectively, and 1.93 log-cfu/g and 5.33 log-cfu /g S. Enteritidis reduction caused in the samples respectively. S. Enteritidis cells were not detected in the whole chicken heat treated at 220°C for 60 minutes. The cakes, heat treated at 160°C top-bottom fan cooking mode for 30 minutes, were stored at two different storage temperatures as 4°C and 25°C for 72 hours. The whole chicken, heat treated at 220°C top-bottom fan cooking mode for 60 minutes, was stored at 4°C for 72 hours. S. Enteritidis cells were not detected in the cake and the whole chicken samples after the storage period.

Irish edible brown (Himanthalia elongata—sea spaghetti, Alaria esculenta—Irish wakame) and red seaweeds (Palmaria palmata—dulse, Porphyra umbilicalis—nori) were assessed for nutritional (proximate composition; salt; pH; amino acid; mineral and dietary fibre contents); bioactive (total phenolic content (TPC) and in vitro antioxidant activity (DPPH and FRAP)); thermal (thermogravimetric analysis (TGA)); and technological (water holding capacity (WHC), oil holding capacity (OHC) and swelling capacity (SC)) properties. Red seaweeds had higher (p < 0.05) protein levels, whereas brown seaweeds possessed higher (p < 0.05) moisture, ash, insoluble and total dietary fibre contents. Nori had the lowest (p < 0.05) salt level. Seaweed fat levels ranged from 1 to 2% DW. Aspartic and glutamic acids were the most abundant amino acids. The total amino acid (TAA) content ranged from 4.44 to 31.80%. Seaweeds contained numerous macro (e.g., Na) and trace minerals. The TPC, DPPH and FRAP activities followed the order: sea spaghetti ≥ nori > Irish wakame > dulse (p < 0.05). TGA indicated maximum weight loss at 250 °C. Dulse had the lowest (p < 0.05) WHC and SC properties. Dulse and nori had higher (p < 0.05) OHC than the brown seaweeds. Results demonstrate the potential of seaweeds as functional food product ingredients.

Storage Temperatures

Popcorn is produced and consumed worldwide, requiring storage to address the demands of consumers throughout the year because production is generally seasonal. Several factors can affect the quality of stored grains, including storage temperature. This study aims to evaluate the effects of different storage temperatures (5, 15, 25 and 35 °C) on the physicochemical, technological, pasting and sensory properties of popcorn grains stored for 6 months. The storage at 35 °C for 6 months promoted an increase in the expansion time and a decrease in the weight of the expanded popcorn as well as a decrease in electrical conductivity, pH and protein solubility of popcorn. Moreover, the greater residue content after the expansion was found for grains stored at 35 °C. These characteristics were reflected in the purchase intent test and in the sensory evaluation. Expanded popcorn prepared with grains stored at 15 °C exhibited larger flower and higher purchase intent characteristics than expanded popcorn prepared from other treatments when evaluated by the sensory panel. Considering these benefits, storage at lower temperatures of approximately 15 °C is preferable to preserve the physical, sensory and technological properties of popcorn.

Face Experiment

Four experiments were aimed at elucidating some aspects of the preference for facelike patterns in newborns. Experiment 1 showed a preference for a stimulus whose components were located in the correct arrangement for a human face. Experiment 2 showed a preference for stimuli that had optimal sensory properties for the newborn visual system. Experiment 3 showed that babies directed their attention to a facelike pattern even when it was presented simultaneously with a non-facelike stimulus with optimal sensory properties. Experiment 4 showed the preference for facelike patterns in the temporal hemifield but not in the nasal hemifield. It was concluded that newborns' preference for facelike patterns reflects the activity of a subcortical system which is sensitive to the structural properties of the stimulus.

Objective: To study the effect of storage temperatures and dehydration conditions (solar and convective drying; SD, CD), on the quality, physicochemical parameters and antioxidant properties of tomato fruits. Methodology: The physicochemical characteristics pH, titratable acidity, soluble solids (°Bx) and color parameters (L*, a* and b*), were evaluated. The lycopene, carotenoids and antioxidant activity percentages retention of tomatoes fruits stored at 7 and 22 ° C for 5 days and subjected to SD (Temperature (T) of 67 °C and luminescence of 685 lum/sqf) and CD (T 70 °C, flow rates 0.5, 1.0 and 1.5 m/s), were analyzed. Results: The fruits reached humidities of 17 and 15% for SD and CD. The parameters pH, °Bx, L*, a*, b* were highest with 22°C and CD (1.5 m/s). The value of the carotenoids was higher in fruits stored at 7 ° C and subjected to CD (1.0 and 1.5 m/s) and SD with values of 83.85, 85.98 and 99.43%, respectively. The CD (0.5 m/s) and SD improved lycopene (94.37 and 95.14%) and the antioxidant activity with values of 73.06 and 97.21%. Implications: The application of solar dehydration depends on luminescence condition; however, it is inexpensive and environmentally friendly alternative. Conclusions: The results derived in a viable alternative for the conservation and commercialization of tomato fruits in rural communities

Pasta was prepared by incorporation of Ocimum sanctum (Basil) for better textural and sensory properties. The pasta was incorporated with the leaf extract of Ocimum sanctum at different concentrations of control, 5, 10, and 15.The natural antioxidants present in the O. sanctum leaf powder that was incorporated in the fruit leather showed extended shelf-life over three months when compared with control, without any added preservative at ambient temperature. Also the nutritional stability of the product was studied under two flexible packages of polypropylene and polyester out of that the products packed in polypropylene showed better storage stability .
