The challenge of providing cocoa seeds is the characteristic of recalcitrant seed, thus requiring storage techniques that can slow down the decline in seed viability in an effort to manage the distribution of cocoa seeds which depend to the time of demand and harvest. The research aimed to study the effect ofpackaging method for storage of cocoa seeds; the effect of shelf life and temperature to germination and water content of seeds, and the stability of seed germination at different age and storage temperature. The research was conducted at Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute, Jember, East Java. The research used complete randomized design with research design using split plot. The treatments consisted of packaging methods, storage temperature and storage life. Packaging methods consisted of two methods, i.e. vacuum methods and non vacuum methods. Storage temperature consisted of three treatments, i.e. 15OC, 25OC and 30OC. both of packaging and temperature treatments were stored at four shelf life treatment included 1 week, 2 weeks, 3 weeks, and 4 weeks. Each treatment was repeated with three replications and each treatment per replication consisted of 50 seeds. Data analysis used SAS 9.0 and stability analysis used R program and PB Tool. Water content of seeds, germination of seeds and number of seedy seeds were observed. The results showed that type of packaging and storage temperature effect to germination of cocoa seeds but did not effect to seeds water content. Storage of cocoa seeds by non-vacuum packaging showed a higher of germination compared to vacuum packaging in all temperature treatments. Storage with non vacuum packaging at a temperature 25OC showed a germination more than 85% for 2 weeks of shelf life, while storage of cocoa seeds at a temperature of 30OC had a germination of more than 85% for only 1 week shelf life. Storage of cocoa seed at 15OC showed the lowest of germination at treatment. Storage treatments did not show effect on water content of cocoa seeds.

<p><em>Coffee is a beverage that is widely consumed around the world. Proper packaging and storage temperature may extend shelf life of ground coffee. The study aimed to analyze the shelf life of ground Arabica coffee stored in different packaging types and temperature, conducted at smallholder coffee plantations in Garut Regency and the Integrated Laboratory of Indonesian Industrial and Beverage Crops Research Institute, Sukabumi, from June to August 2018. A completely randomized design in factorial was used with 3 factors and 2 replications. The first factor was the packaging type  which consisted of 3 types: thick alumunium  foil 65</em><em>m</em><em> (AF65), thick alumunium  foil 130</em><em>m</em><em> (AF130), and thick lamination 114</em><em>m</em><em> (L144). The second factor was the storage temperature which consisted of 3 levels: 25 <sup>o</sup>C, 35 <sup>o</sup>C, and 45 <sup>o</sup>C, while the third factor was the storage period which consisted of 5 levels: coffee unstored, and coffee stored for 2 weeks, 4 weeks, 6 weeks, and 8 weeks. The variables observed were the water and fat content, and the analysis of shelf life was carried out using the ASLT (Accelerated Shelf Life Test) method. The results showed that during storage, the water content increased, whereas the fat content decreased. Fat content is a critical variable in determining the shelf life of coffee. The coffee in AF130 packaging has longer shelf life than in AF65 and L144. To extend the shelf life of coffee packaged in AF130 and L144 is best kept at 45<sup> o</sup>C whereas coffee in AF65 packaging  is ideally at 25<sup> o</sup>C.</em></p>

Edible film made up of modified tapioca was used to wrap tempeh and its shelf life estimation was determined. The edible films must be capable of evenly aerating and maintaining moisture without causing condensation in order mycelium to be able to grow and produce high-quality tempeh. The experiment was carried out in completely randomized design with two main factors of storage temperature and time. An accelerated shelf life test at 17oC, 27oC, and 37oC with an Arrhenius model was used to calculate the shelf life, and water content was used as quality parameter indicator. The result showed that modified-tapioca based edible film made from fermentation of tapioca by Saccharomyces cerevisiae was characterized as having elongation of 11.40 %, tensile strength of 408.37 MPa, thickness of 0.88 mm and WVTR of 12.60 g/m2/h. Rate constant of water content decrease in edible film wrapped tempeh based on Arrhenius model was 0.3832 % day-1 and Ea was 10.296 kkal/gmol, while that of in PP-plastic wrapped tempeh was 0.3831% day-1 and Ea was 9.998 kkal/gmol. The shelf life of edible film wrapped tempeh was 9.39 days at 27oC, 5.18 days at 27oC, and 2.96 days at 37oC, while shelf life of PP-plastic wrapped tempeh was 8.64 days at 17oC, 4.85 days at 27 oC, and 2.82 days at 37oC. Therefore, it can be concluded that modified tapioca based edible film increased the shelf life of tempeh.

All foods have limited shelf life which vary depending on the food and storage conditions. Table eggs are perishable food and storage temperature is an important factor that affects the shelf life. In tropical countries like Nigeria, eggs are usually preserved under ambient condition due to erratic power supply, which reduces the efficiency of refrigeration system. The aim of the present study was to examine the effects of storage periods, temperature and their relationship on the pH of chicken egg internal properties (yolk, albumen and whole egg). Fresh chicken table eggs were randomly allotted to three treatments of storage temperatures; refrigerator (40C ? 2), laboratory (320c ? 4), and poultry store room (370C ? 4). Eggs were assigned to treatments in a completely randomized design, and each treatment was replicated thrice. The pH was measured daily for each storage temperature in all treatments. Storage temperature and periods had significant (P<0.05) effect on pH of measured parameters. The pH values increased with storage temperature and period of storage. The rate of pH increase was significantly (P<0.05) higher in ambient as compared to refrigerator temperature. In this study, only the refrigerator storage has pH values within the range for fresh table eggs. At storage period above three weeks, pH values increased beyond the range for fresh egg. It is validated that storage temperature and period affected egg shelf life, the rate of freshness reduced with increased temperature, thus, storage beyond three weeks of ambient temperature is not advisable in humid tropics.

This study assesses the storage temperature effect on the anthocyanins of pasteurized and unpasteurized açaí pulp. The data was obtained using a pasteurized and lyophilized pulp (PLP) to evaluate the temperature effect (0, 25, and 40 °C). Part of non-pasteurized frozen pulp (NPP) was pasteurized (NPP-P) at 90 °C for 30 seconds; both pulps were stored at 40 °C. The anthocyanin content reduction in the drink was evaluated from the half-life time (t1/2), activation energy (Ea), temperature quotient (Q10), and the reaction rate constant (k). The t1/2 of the PLP anthocyanins stored at 40 °C was 1.8 times less than that stored at 25 °C and 15 times less than that stored at 0 °C; therefore, the higher temperatures decreased the stability of anthocyanins. The pasteurization increased the t1/2 by 6.6 times (10.14 hours for NPP and 67.28 hours for NPP-P). The anthocyanin degradation on NPP-P followed a first order kinetic, while NPP followed a second order kinetic; thus it can be said that the pasteurization process can improve the preservation of anthocyanins in the pulp.

Isothiocyanates (ITCs) contained in purees extracted from wasabi (Wasabia japonica (Miq) Matsum) can be used to manufacture a range of interesting spicy foods. In New Zealand, local manufacturers are showing interest in producing various forms of processed wasabi based sauces. However, isothiocyanates have been shown to degrade quickly in some situations. Therefore, in this study, the stability of allyl ITC was investigated in three wasabi flavoured products stored at four different temperatures (4, 10, 20 and 30°C) for 22 weeks. Two creamy (mayonnaise and tartare) sauces and a non-creamy sauce were prepared from an original recipe and flavoured with a known volume of "wasabi oil". Two types of pouches (clear and metallic plastic) were used to store each product and allyl ITC content was measured in the stored sauces at two week intervals. The initial level of allyl ITC found in mayonnaise, tartare and smoky tomato sauces were 415.3, 411.4 and 144.7 mg/ kg respectively, prior to storage. Temperature showed a strong influence in reducing allyl ITC (P=0.005 to <0.001) but no significant effect was identified for the two types of packets used. The non-creamy smoky tomato sauce was very unstable at 10°C or higher temperatures and the allyl ITC contents reduced rapidly with increasing storage temperatures. For instance, at 30°C, a 66% loss occurred by week 2 and a 90% loss occurred by week 6 in the smoky tomato sauce. However, mayonnaise and tartare sauces had a shelf life of 8 to 9 weeks with only a marginal reduction in allyl ITC (2% overall) at all the stored temperatures (4-30°C). These creamy sauces were characterized by a sudden fall in 10 weeks ending in a 69-70% loss of allyl ITC at 22 weeks. No microbial growth occurred in any of the sauces stored at any of the temperatures during the course of this storage experiment though very small change of colour was noticed for the sauces when stored at 30°C.
