The objective of this study was to evaluate the effect of marigold flower extract and paprika on egg quality of Black Avifran laying hens in different periods of storage. A completely randomized design study with a 3x3 factorial scheme with three diets (control, paprika, and marigold flower extract) and three storage periods (0, 7, and 14 days) was carried out. The following metrics were evaluated: egg weight, yolk weight, shell weight; yolk color, albumen height, specific gravity, and Haugh unit as well as the yolk, shell, and albumen percentage relative to the total weight of the egg. There was no significant interaction between additives and storage time (p > 0.05) for most of the parameters evaluated. The only exception was observed for yolk color, in which the interaction effect between treatments was significant (p < 0.05). The effect of storage time was significant (p < 0.05) for albumen weight, albumen percentage, yolk color, albumen height, specific gravity, and Haugh unit, with reduction of these parameters over the evaluation period. The use of paprika and marigold flower extract in the diets of Black Avifran laying hens does not influence egg quality.

Quail eggs is one of the perishable food. If left in the open air at room temperature, the shelf life ranged between 10-14 days. Preservation is one of the way to prolong shelf life which can be done by soaking the eggs in a gelatin solution. The purpose of the study was to know the physical quality of quail egg soaked in gelatin bone chicken feet long with different time of storage. The experimental design of this study was Complete Randomized Design (CRD) factorial pattern 3 x 3 with 5 replications. The first factor was soaking time (0, 30 and 60 minutes) and the second factor was storage time (0, 15 and 30 days). The results showed that there was nos ignificant effect of soaking period (P>0.05) on egg weight, egg white index, yolk index, Haugh units and pH. The longer the storage time, the egg weight, egg white index, yolk index, haugh unit were decreased and the other hand, pH value was increased. Soaking quail eggs in gelatin solution of chicken feet during 30 minutes and storage time for 15 days resulted in pH value almost the same with untreated egg(control).

The effect of different composite coatings on quality of semi-moist apricot cubes mixed with cornflakes was investigated during 180 days of storage. The apricot cubes were osmotically dehydrated (OD) and coated before hot-air drying (HAD) at 60 °C. Chitosan-bees wax (CBW) and whey protein isolate-bees wax-oleic acid (WPI-BW-OA) coatings were applied after HAD and the samples were added to cornflakes. Application of OD and pectin-ascorbic acid (Pec-AA) coating (prior to HAD) and WPI-BW-OA coating (after HAD) led to significant retention of total phenol compounds, β-carotene and antioxidant activity in apricot cubes compared to uncoated and CBW-coated samples. WPI-BW-OA-coated samples gave significantly higher L* values (lighter color) and b* values (more creamy or yellowish color) and lower a* values (less reddish color) and browning values than control followed by CBW-coated apricots at any time of storage (p < 0.05). The rate of apricot moisture loss and cornflakes moisture gain was higher in uncoated apricot cubes, followed by CBW- and WPI-BW-OA-coated samples. Application of WPI-BW-OA coating was effective in retaining the crispness measured by lower firmness (Fmax) values in cornflakes upon storage. Based on the obtained results, WPI-BW-OA coating allowed effectively preserving the quality characteristics of semi-moist apricot cubes and cornflakes components in the mixed state.

Rahman AS, Purwoko T, Nugraheni ER. 2011. The influence of ethanol extracts concentration of mengkudu fruit (Morinda citrifolia) and storage time toward beef quality. Biofarmasi 9: 26-32. The high protein content of beef makes it easy to get a contamination caused by an activity of bacteria. The use of formalin as a preservative substance especially for beef can make a damage to health, so it is required to find preservative substances as alternative to substitute formalin. Mengkudu (Morinda citrifolia L.) has antibacteria compounds to the decompose bacteria of beef, so mengkudu fruit can be one of natural preservative substance alternatives, especially for beef. The purposes of this research were to determine the influence of ethanol extracts concentration of mengkudu fruit and a storage-time effect toward bacteria amount, and to determine the concentration that had a same activity with formalin to combate the replication of bacteria. This research used two-way completely randomized design. The samples were fresh meat beef that be submerged in mengkudu extract with concentrations of 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100% and formalin 1% as a comparator. After that, the beef was storaged in a room temperature during 16 hours, and every 4 hours it was tested for water content, pH value, beef temperature and a total plate count (TPC) test with a dilution method, and then the number of bacteria colonies with the limit of the bacteria amount of the beef to consume might not be more than 1x104 CFU/gram. The data were analyzed by ANOVA. If there was a significance, it would be continued by a DMRT test with an error rate 5%. The research results showed that all extracts concentration of mengkudu fruit and storage-time gave a significant effect (p<0.05) toward bacteria amount. The concentration of 100% had the same activity with formalin to combate the replication of bacteria among 16 hours storage time.

Seeds of native forest species for food and seedling production have a growing demand that impacts the need for studies involving seed storage in order to maintain good levels of germination quality. Thus, scientific analyzes that explore the physiological potential of the seeds of these species are necessary, especially for the pink pepper (Schinus terebinthifolia Raddi.), a species used as an alternative source of income for traditional communities and which has been arousing interest due to the consumption of its fruits as a condiment in the national and international market. This work aimed to assess the physiological quality of pink pepper seeds according to the storage period and seed size. The seeds came from a rural settlement, a pioneer in the extraction of pink pepper, in the state of Rio de Janeiro, Brazil. The seeds were evaluated for moisture content, germination, first count, length and dry weight of the germinated seedlings, during the period of time that they remained stored and the size of the seeds. The results allowed to conclude that: i) the germinative percentage of the stored pink pepper seeds decreased over the months; ii) the moisture content of the seeds decreased over the months evaluated iii) the different sizes of seeds did not show differences in germination and storage time and iv) values of length and dry weight of the seedlings did not differ according to the period of storage.
