Nine types of packaging materials were tested on this study Included (I) Polyethylenetetraphthalate (PET) Bottle, (ii) Polypropylene (PP) Cup, (iii) polystyrene (PS) Cup, (iv) Low density polyethylene (LDPE) Bottle, (v) Light Proof Polyethyleneterephthalate(LPET) Bottle,(vi) High density Polyethylene(HDPE) Bottle, (vii) Aluminum Cans, (viii) Glass(Emerald Green) and (ix) Cartoon bottles (250 ml size) were dispensed in the aseptic condition with Pasteurized camel milk (80 ˚C,16s) for two seasons Summer and Winter and stored immediately inside the chiller at 5 ˚C for 30 days, The camel milk samples were examined for microbial quality, sensory evaluation, also food packaging materials were examined for overall migration test, approximate shelf life of the pasteurized camel milk at temperature 5 ˚C in all types of packaging materials in our study period 30 days, Sensory Evaluation results shown that there is significant differences within best packaging materials, so we can say best packaging materials not same in summer and winter. We see also the best packaging materials is not same in winter of all type of Sensory Evaluation with one ranking (PS, HDPE) respectively, but not difference in summer, so the best in winter is (PP - PS – PET) respectively, lastly the overall migration test analysis for the food packaging materials shown that there are no significant differences within packaging materials. So we can say responds in group equally at all packaging materials and all samples meets the specification limits as per Article 12, EU 10/2011.

Background: Providing nutritionally adequate complementary foods is essential in preventing malnutrition in young infants. Koko made from fermented corn dough constitutes the most common complementary food in Ghana. However, these do not meet the nutrient requirements. Objective: To develop and test the acceptability and shelf-life of an energy-dense complementary food supplement for improving the nutritional profile of traditional complementary foods. Methods: Surveys of families in urban and rural communities and stakeholder engagements with health professionals were done to identify the most predominant traditional complementary foods and young infants’ feeding practices. A food supplement, KOKO Plus, that would improve the nutritional profile of koko and other complementary foods needed to be developed. Linear programming was used in ingredient formulations for the food supplement based on locally available foods. The acceptability of the food supplement, KOKO Plus, in koko and soup was assessed using 14 trained assessors in a 2 × 2 crossover design. Shelf-life of the product was estimated using the difference in control sensory test method at different storage temperatures (24°C, 34°C, and 44°C). Results: Koko was the most predominant complementary food in many homes. The KOKO Plus food supplement improved the nutritional profile of koko to satisfy the nutrient intake requirements of young infants as recommended by World Health Organization. KOKO Plus was microbiologically safe, with estimated shelf-life of more than 12 months. Conclusion: The development of KOKO Plus as a food supplement provides a practical solution to improve the nutritional status of weaning children in Ghana.

Muscadine Grapes

Muscadine grapes (Vitis rotundifolia Michx.), native to the southeastern United States, have a distinct flavor, and grocers are interested in marketing them as table grapes. Two studies using 'Fry' muscadines were conducted to assist the muscadine industry in providing quality table grapes. Study 1 (1998 and 1999) evaluated density sorting and relationships between maturity, color, soluble solids, firmness, shelf life, and sensory evaluation of grapes. Study 2 (1998) determined the effect of storage on quality attributes of different maturities of grapes and evaluated use of polyethylene bags to extend their storage. Density separation successfully sorted grapes by maturity. Muscadine berry color may allow for visual or electronic sorting to eliminate immature fruit. Sensory panelists could distinguish differences in maturities for all sensory attributes. In 1999 maturities 3 and 4 (≈24-33 soluble solids: acid ratio) were preferred overall by panelists. As maturity increased, soluble solids and pH increased, and acidity decreased. Firmness decreased as maturity and storage at 2 °C increased. Percent decay increased with maturity and storage time. Grapes stored in polyethylene bags had reduced decay. A chart developed from the 1999 data related berry color to soluble solids: acid ratio, soluble solids, tartaric acid, and pH. Data from these studies can be used by industry to establish harvest parameters and enhance marketability of 'Fry' muscadine grapes.

Model storage experiments of pasteurised tomato puree and ketchup were carried out. The sets of samples were boiled at 100°C, during the heating the changes of selected markers were followed and correlated with the sensory evaluation, the markers were: furosine, 2-furaldehyde, 5-hydroxymethyl-2-furaldehyde (HMF) and colour (expressed as: <I>L, a*, b*, a*/b*</I> and &Delta;<I>E</I>). The suitability of selected markers for the assessment of temperature impact on tomato products was evaluated. The correlation matrix for the followed markers of the tomato puree and ketchup was calculated and the courses of changes (expressed as velocity constant) of the markers were compared.
