Proximate Analyses

Ostrich meat is very popular due to its healthy composition thereby increasing its demand globally. Therefore, one study has been made on quality of ostrich meats of different ages at chilled and frozen conditions by targeting product development. Meat samples from two differently aged, 10- and 14-months ostriches were collected and divided into three parts for each type. One part was analyzed immediately, one part was put in chilling at 4°C for 72 hours and next part was put in deep fridge at -20°C for 30 days. Proximate analyses were carried out for moisture (73.98 to 75.22%), protein (21.08 to 22.46%), total fat (2.43 to 3.27%) and total minerals (0.83 to 1.82%). There was subsequent decrement in moisture at cold storage practices, at 72 hours chilling by 1% and one month freezing by 2.3% and there was no significant (?) difference in water content due to the age of bird. The amount of protein was found increasing at chilling, freezing and ageing? total fat was significantly different due to the age as well as meat storage practices and total ash was in decreasing trend in case of chilling and freezing conditions but found no difference due to the age.

Temperature Scenario

Sorghum (S. bicolor) collected from Dhankuta district was used for malting. Sorghum was steeped for 12 hours at Relative humidity of 70±5% and germinated at room temperature (28±3°C) with repeated change of water at interval of every 8 hours for 2, 3,4,5,6 and 7 days. The germinated samples of each day were taken for kilning at the temperature scenario of 50-55°C until moisture reaches to 23%; 70-75°C until moisture reaches to 12%; and 90-95% until moisture reaches to 3-5%. The result of enzyme activity determination showed that the sorghum germinated for 3 days has the higher enzyme activity of 27.39 units per gram dry matter. Proximate analysis of malted and unmalted flour showed significant different (p<0.05) in fat, ash, reducing sugar and crude fiber content. Likewise calcium and iron content of malted flour was significantly increased (p<0.05) than that of unmalted one with subsequent decreased (p<0.05) in their binder oxalate and phytate respectively. The sorghum of higher enzyme activity was then used to prepare the biscuit. Malted sorghum and wheat flour was blended in the following ratios: samples A; 30: 70, sample B; 50:50, sample C; 60:40, sample D; 0:100. The organolaptic test shows the significant difference (p<0.05) between these samples in terms of flavor and test. The mean sensory score was found to be higher for sample C. This suggests that the malted sorghum flour can be used for the preparation of biscuit upto 60% (w/w) of wheat flour without alteration in texture, crispiness, appearance and overall acceptability.Sunsari Technical College Journal 2015, 2(1):33-37

Different aminopeptidase and endopeptidase substrates were assessed for the detection of enzymatic activity of microorganisms collected from the surface of aerobically cold-stored pork and beef. The most sensitive substrates were fluorogenic Ala-7-amino-4-methylcoumarin (Ala-AMC) or Leu-AMC and colorogenic Ala-p-nitroanilide (Ala-pNA). Activity on natural oligopeptides, e.g., bradykinin or αs1 casein fragment 1 to 23, was very low. The correlation coefficient (r) between log surface counts of 66 meat samples and log fluorescence or absorbance after incubation of surface microbial cells for 2 h with Ala-AMC, Leu-AMC, and Ala-pNA was 0.89, 0.83, and 0.82, respectively. A distinct yellow color was obtained with Ala-pNA when the surface count was ∼106 CFU/cm2. Although correlation and sensitivity was better, no clear advantage is obtained with the use of the fluorogenic Ala-AMC or Leu-AMC instead of Ala-pNA, a substrate proposed by Alvarado et al. (J. Food Sci. 57:1330, 1992) for rapidly assessing the microbial quality of refrigerated meat. The correlation coefficient (r) between time of cold storage and surface count was 0.69.

The physiological quality of seeds of native species is important to produce healthy saplings and therefore guarantee the success of programs to recover disturbed vegetation. This reinforces the necessity for investigating the physiological quality of those seeds. To evaluate the effects of different drying rates on the germination, moisture content and storability of Eugenia involucrata diaspores, mature fruits collected at Mogi Guaçu, SP, Brazil had their epi- and mesocarps removed by washing and were dried at 30, 40 or 50ºC until their water content was reduced from 57% (fresh diaspores) to 13% (final drying), totaling six drying levels. In a second experiment, diaspores had their moisture content reduced from 57% to 49%, at 30ºC, totaling six drying levels (0h, 1h, 2h, 3h, 4h and 5h), and were kept for 180 days in plastic bags under cold storage. The drying rate had no effect on tolerance to desiccation by E. involucrata diaspores; water contents lower than 51% decreased both germinability and storability. Diaspores can be stored for up to 180 days as long as their water content is reduced to 53% and they are kept inside plastic bags under cold storage.

PE/thermochromic composite membrane is a kind of new functional materials which is composited by PE and thermochromic membrane.PE/thermochromic composite films retain the thermochromic membrane performance of changing the color by absorbing the heat. The composite film cannot be dissolved by water because of the structure which PE film is attached to the both sides of thermochromic film.The effect of the composite film and Nylon/low density polyethylene (LDPE) film on quality of fresh pork meat stored were investigated respectively. The treated meat samples were analyzed periodically for color difference. The results indicate that preservation effect of both films has no significant difference when the fresh pork are stored at 3-5°C, but PE/thermochromic composite films has better preservation effect at 30°C in compared to the Nylon/ LDPE. filmsfilms

Abstract Green asparagus was treated with 1-methylcyclopropene at three concentration levels at room temperature for 24 h after harvest to evaluate the postharvest quality during cold storage at 4°C. Comparing with the controls, the loss of vitamin C, decomposition of chlorophyll, and accumulation of the malonydiadehyde under treatments of 1-methylcyclopropene were reduced during storage. The enzyme activities in asparagus including peroxidase and phenylalanine ammonia lyase were inhibited by 1-methylcyclopropene treatments, while the activity of superoxide dismutase was enhanced. Based on non-significant difference of the treated samples with 6 ìl l-1, 1-methylcyclopropene treatments at 4 ìl l-1 could be selected to maintain postharvest quality of green asparagus and provide long storage life.

Aim of study: Beef quality is mainly affected by finishing feeding (FF) and production system (PS). The effects of PS (extensive, semi-extensive, traditional and intensive systems) and FF from Rubia Gallega calves were compared in terms of meat quality.Area of study: Galicia (NW Spain)Material and methods: Calves (n=10 per treatment) were slaughtered at nine months of age and meat samples were assessed in terms of meat quality attributes such as physicochemical, nutritional and sensory analysis performed by a trained panel.Main results: Meat chemical composition varied (p<0.01) with PS and FF. The semi-extensive system showed the lowest values (p<0.05) for cooking loss (22.8%) and for shear force (26.0 N) while the extensive system presented the lowest contents of saturated fatty acids (SFA) and the highest contents of linolenic acid (p<0.001). The SFA and polyunsaturated fatty acid (PUFA) contents varied with FF (p<0.05). The lowest and highest values for SFA and PUFA were displayed in extensive group finished with Pasture/Concentrate, meanwhile feedlot group finished with Concentrate/Straw showed and opposite trend. The n-6/n-3 ratio was lower than 4 for extensive and semi-extensive systems (p<0.001). In addition, tenderness and juiciness showed significant differences mainly due to FF.Research highlights: This study showed that meat of calves reared in extensive systems was the healthiest, regarding total fat and fatty acid composition. It can be concluded that finishing feeding, and PS affected meat quality. Hence the potential usefulness of these results is to improve meat quality and safety according to market demands.

The study aimed to examine the quality of honey from the Middle Podrinje area (Bosnia and Herzegovina). The research included a total of 21 samples of honey from the Middle Podrinje area: 12 samples of honey florals (municipalities of Srebrenica and Milići), 9 samples of acacia honey (municipalities of Zvornik and Bratunac). Physico-chemical parameters were determined as the main composition criteria for quality assessment in honey samples: mass fraction of water, total acidity, electrical conductivity, and ash. Samples of honey florals are of poorer quality compared to acacia honey, two samples had values of water content and acidity above the values prescribed by the Regulation. Statistical analysis showed that there is a statistically significant difference between the arithmetic means of the water content for floral honey, the electrical conductivity of acacia honey, and the free acid content for both types of honey. Honey samples that met the criteria prescribed by the Regulation were sensory evaluated by experienced analysts. Two samples of floral honey that did not meet the criteria prescribed by the Regulation were not sensory evaluated. Based on sensory analysis, samples of floral honey from the municipality of Milići had better sensory characteristics compared to the same type of honey from the municipality of Srebrenica. Acacia honey from the municipality of Zvornik was rated better than honey from the municipality of Bratunac.
