Opis:
Injera is one of the fermented foods that is made from different cereals, including sorghum, teff, maize, wheat, barley, or a combination of some of these cereals. Despite the fact that injera is a favorite staple food, mould spoilage caused by Aspergillus, Penicillium, Mucur and Rhizopus spps is a serious problem that affects the shelf life of injera, the staple Ethiopian fermented bread. There were no reports on the efficiency of spices on shelf life and sensory attributes of any of the traditional Ethiopian fermented foods especially in teff injera. Therefore, this study was carried out to evaluate the efficiency of locally available spices to enhance the shelf life and sensory attributes of teff injera. Isolation and identification of fungi that spoiled injera was carried out by standard procedures. The efficiency of spices to increase shelf life of injera was evaluated in vivo and sensory attributes of preserved injera was evaluated by 30 panelists. The results revealed that four types of fungal species belonging to the genera of Penicillium, Aspergillus, Rhizopus and Mucur species were isolated from spoiled teff injera. Teff injera containing powder and water extract of 2% N. sativa were the most preferred in terms of taste with mean rating of 6.9; ethanol extracts of 2% N. sativa was the most preferred in terms of colour and allover acceptance with mean rating of 6.9and 6.93 respectively. On the basis of the current findings, tested spices could be a good candidate to improve the shelf life and sensory attributes of teff injera. Therefore, further studies are needed to study their toxicology and isolate the bio-active components responsible for shelf life and sensory improvement from these plants.

Opis:
This research aims to determine the shelf life of catfish skin crackers in polypropylene plastic packaging using the ASLT method. This test was conducted in the Fisheries Product Processing Laboratory of the Faculty of Fisheries and Marine Sciences, Padjadjaran University and testing the content of water content and TBA (Thiobarbituric Acid) of catfish skin crackers at the Food Technology Laboratory, Faculty of Food Science Technology, Padjadjaran University from September to November 2018. This study used an experimental method consisting of 3 storage temperature treatments at 25 ºC, 35 ºC and 45 ºC. Observations carried out include sensory (hedonic) test, water content test, and TBA (Thiobarbituric Acid) test. For the calculation, Arrhenius model was chosen with odor as a critical parameter to determine the shelf life which had the biggest R2 value with equation Arrhenius Ln K = 1079.8 (1/T) – 5.5161, with R2 value equal to 0.9212. The shelf life of catfish skin crackers that was saved at the room temperature (25 ºC) was 39 days or 1.3 month.

Opis:
The purpose of this research is to determine the effectiveness of turmeric and its best concentration in preserving the presto of lalawak fish based on the characteristics of microbiological tests and chemical tests including checking water content and pH. The research experimental method covered five treatments by adding turmeric extract solutions of 0%, 1%, 3%, 5%, and 7%. The test parameters observed in the research were microbiological tests using the method of TPC (Total Plate Count) in duplicate and chemical tests including checking water content and pH. The results showed that all treatments by adding turmeric extract were with concentrations of 1%, 3%, 5%, and 7% able to extend the shelf life presto of lalawak fish more than two days compared to the presto of lalawak fish which were not treated with turmeric extract or control (0%) which can only last two days. The treatment of the addition of 5% turmeric extract is able to provide the long lasting strength of lalawak fish for up to five days so that the shelf life is longer than other treatments, as evidenced by the TPC (Total Plate Count) value of 5.81×105 CFU / gram on the 6th day. The water content reached 67.5% on the 6th day and the pH value reached 6.50 on the 5th day.

Opis:
The purpose of this research is to determine the best concentration and effect of garlic extract incorporated on tilapia skin gelatin-based edible coating to preserve and extend the shelf life of fish meatball at cold storage. This research was conducted from May 2018 until October 2018 on Fisheries Product Processing Laboratory of The Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The garlic extract conducted with maceration method with ethanol 96% was performed at Organic Chemical Laboratory FMIPA Universitas Padjadjaran, and for TPC test, inhibition test of edible coating Tilapia’s fish-skin with garlic extract was conducted in Microbiology and Molecular Biotechnology Laboratory of Faculty of Fisheries and Marine Sciences Universitas Padjadjaran. The method used is experimental method with 5 treatments which is meatballs without edible coating. The addition of garlic extract was done with various concentration at 0%, 1%, 1.5%, 2%. The observations were Total Plate Count (TPC) test, inhibition zone test against Pseudomonas aeruginosa, and pH value. The results showed that the best treatment is 2% garlic extract with TPC value 1.1×105 cfu/g during 14 days of storage and concluded that it could extend the shelf life of meatball until 14 days, pH value was 7.03 and inhibition zone against P. aeruginosa was 7.01 mm. The addition of garlic extract on tilapia skin gelatin-based edible coating could extend the shelf life of fish meatballs until 14 days on cold storage.
