Mentha x piperita L. simplicial  may undergo deterioration during storage, therefore it is very important to determine its shelf life. The determination of shelf life was done using Extend Storage Studies (ESS) method. This study was aimed to determine the shelf life and the effect of storage time on organoleptic simplicia M. x piperita. The sample used was simplicia that has been stored for 0, 15, 22, 30, 32, and 44 mounth in the simplicia storage warehouse with some long storage, and then the samples were subjected for moisture content analysis and organoleptic evaluation. The results showed that the shelf life of M. x piperita simplisia determined using the method of a water content parameter approach was 27 months. After 27 months of storage, although the aroma still can be preserve, there wa a decrease in the taste  and the color of simplisia.  In addition, there was increase in water content.

Two monovarietal extra virgin olive oils (Arbequina and Coratina), produced in Uruguay, were studied over a period of 12 months storage in amber bottles at 30 ºC. Peroxide index, K232, K270, ∆K, OSI induction time did not exceed the maximum limits set by the International Olive Council (IOC) during the entire period. However, the content of ethyl esters increased with storage time and it is in relation with the shelf life. The International Olive Council (IOC) establishes the limits in the content of ethyl esters ≤ 35 ppm. The Coratina oil ceased to be extra virgin quality after 6 months of storage due to its content of ethyl esters (46 ppm), and the Arbequina oil after 9 months (52 ppm).Taking into consideration their content of ethyl esters, both the Arbequina and Coratina oils showed a very short shelf life less than six months. The determination of ethyl ester content proved to be a sensitive method for determining the loss of quality of extra virgin olive oils.

Andaliman  is  typical spice plant in North Sumatra, has benefits as antimicrobial and antioxidant. Tempeh is a protein source food, has short shelf life, so the tempeh processing technology is needed to create another product with  longer shelf life and increase its added value. One of them is by processing tempeh into nugget. The purpose of this study was to determine the shelf life of tempeh nugget added with andaliman fruit extract as  natural preservative and to determine which concentration was the most optimal in extending the shelf life of tempeh nugget. This study used  completely randomized design with two factors. Factor I was the concentration of andaliman extract (0%, 0.1%, 0.25%, 0.5%) and factor II was the storage time (0 day, 7 days, 14 days, 21 days). The parameters analyzed were total microbial, water content, and aroma organoleptic test. The results showed that the addition of 0.5% andaliman extract and 21 days storage time obtained the lowest amount of microbes, the lowest water content was obtained at 0% andaliman extract and 21 days storage time treatment, while the highest aroma organoleptic test was obtained at adding 0.5% andaliman extracts. This is due to the presence of antimicrobial in andaliman

Potato (Solanum tuberosum L.) is one type of tubers are widely consumed by the community because it tastes good and contains high carbohydrates. Potato damage easily occurs because the water content in potatoes is high enough that is 80 percent. Based on that, it is necessary to do the processing to extend the life of the potato store. This study aims to determine the effect of packaging type and storage time to the value of TBA, FFA, Water Content and Sensory Character of Potato Chips. This study used a factorial completely randomized design consisting of 2 factors: packaging type (PP, PE, and aluminum foil) with each thickness of 0.5 mm and storage time (0 days, 7 days, 14 days, 21 days and 28 day) in room temperature. The result of statistical test showed that the type of packaging and storage time had an effect on FFA value, water content and sensory character of potato chips while the value of TBA had no significant effect. Level of potato chip TBA at end of shelf in packing PP 2,412 mg malonaldehid / kg sample, PE 3,365 mg malonaldehid / kg and aluminum foil 2,787 mg malonaldehid / kg sample. FFA value at end of shelf life on packing PP1,173% ALB sample, PE 1,548% ALB sample, and Alumunium foil 1.173% ALB sample. Water content at end of shelf life on PP 7.040%, PE 3,933%, and Alumunium foil 3,003%. The result of statistical test shows that there is influence of packaging type and storage time to FFA value, water content and sensory character of potato chips.

Healthcare associated infection is one of the common infection that happens in Indonesia. One form control to prevent healthcare associated infection is the sterilization process of the materials and medical instruments that used for taking care of patients. At the private hospital whereas a place of research, there’s never been done the study of sterility test for reusable instrument with pouches, based on previous studies showed that 8 sets from 40 sets of reusable instrument with linen were not sterile moreover there were positively influence from the amount of time to the sterility of reusable instrument. The purpose of these studies was to determining the relationship between a long storage time and the sterility of reusable instruments with pouches. The method that used in this study was the sterility testing of reusable instrument with pouches which were stored in a central operations room storage with a long storage time of 1 and 2 months. From 30 reusable instruments with pouches which were stored for nine months there were 5 instruments were not sterile. The results of statistic analysis showed that the amount of storage time not significantly associated to the sterility of reusable instrument with pouches in the operating room central storage space.

The article reflects the assessment of the quality of sour cream at home, and considers methods for determining the quality of sour cream. Organoleptic evaluation was performed for compliance with the requirements of GOST 52092-2003 " Smetana. Technical conditions " in terms of appearance, consistency, color, taste and smell. The consistency of sour cream is determined during its mixing, while evaluating the presence of a glossy appearance of sour cream. Sour cream is considered thick if it slowly drains from the whorl. The smell is determined immediately after mixing. Then we evaluate the taste. When evaluating the quality of the samples under study, it was found that the organoleptic characteristics of the samples fully comply with the requirements of the regulatory document. Analyzing the results of the experiment, we can conclude that in the first experiment, the sour cream purchased on the market was completely dissolved, and the sour cream from the store after dissolution showed small grains. And in the second experiment, the results showed that the color did not change in the sample # 2, but under # 1 it turned blue. The basis of this experiment is a qualitative chemical reaction to starch, which is used as a thickener.
