The effects of a dose of 2.0 kGy (Co-60) and three ranges of storage temperature (0-4°C, 9-11°C, 18-19°C) on increasing the shelf-life and some quality properties of the mushrooms were investigated. The retardation of mushroom growth and ageing by ionizing radiation was estimated by measurements of the cap diameter, stem elongation, cap opening and discoloration of cap surface. The control of fungal and bacterial diseases was also evaluated. The effect of lower doses, 0.5 and 1.0 kGy, was compared at the storage temperature of 10°C. The irradiation of mushrooms soon after harvest and storage at temperatures of 10 and 16°C allowed the retention of quality and increased the shelf-life to 8 days; at 18-19°C to 6 days.

Abstrak. Merupakan salah satu komoditi buah-buahan yang memiliki nilai ekonomi dan banyak digemari masyarakat. Manggis merupakan salah satu buah yang memiliki umur simpan yang relatif singkat, setelah itu manggis akan menjadi busuk dan tidak layak lagi bila di simpan di ruangan, Oleh karena itu perlu dilakukan pengemasan dan penyimpanan pada suhu dingin untuk mempertahankan masa simpan buah manggis. Penelitian ini bertujuan untuk melihat pengaruh kemasan plastik dan suhu penyimpanan terhadap masa simpan buah manggis.Abstract. Is one of the commodities fruits that have economic value and much-loved community. Mangosteen is a fruit that has a relatively short shelf life, after that mangosteen will be rotten and unfit when stored in the room, therefore it is necessary for packaging and storage at cold temperatures to preserve the shelf life of the mangosteen fruit. This study aims to look at the effect of plastic packaging and storage temperature on the shelf life of the mangosteen fruit.

<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>

The influence of different cooling techniques (dry ice/ice packs) and storage temperature (-2°C/3°C) to prolong the shelf life of Arctic charr (Salvelinus alpinus) fillets were evaluated by sensory analysis, physical methods, chemical and microbial analysis. The effects of storage temperature were stronger than of different cooling agents. Superchilling (-2°C) of fillets packed with dry ice resulted in 6 days extension of shelf life compared to chilling (3°C). The use of dry ice parallel to superchilling prolonged shelf life for 1 day compared to fillets stored with ice packs. No negative effects on quality of the fillets where detected that could be linked to cell destruction caused by partial freezing or to sour taste, caused by absorption of CO2 gas in fish flesh.

Two commercially available organic acid salts, potassium lactate (PURASAL HiPure P) and a potassium lactate–sodium diacetate blend (PURASAL Opti.Form PD 4), were assessed as potential inhibitors of Listeria monocytogenes growth in modified atmosphere packaged (MAP) sliced ham in challenge studies. The influence of the initial inoculation level of L. monocytogenes (101 or 103 CFU g−1) and storage temperature (4 or 8°C) was also examined. The addition of either organic acid salt to MAP sliced ham strongly inhibited the growth of L. monocytogenes during the normal shelf life of the product under ideal refrigeration conditions (4°C) and even under abusive temperature conditions (i.e., 8°C). During the challenge studies and in the absence of either organic acid salt, L. monocytogenes numbers increased by 1,000-fold after 20 days at 8°C and 10-fold after 42 days at 4°C. Both organic acid salt treatments were found to be listeriostatic rather than listericidal. The addition of either organic acid salt to the MAP ham also reduced the growth of indigenous microflora, i.e., aerobic microflora and lactic acid bacteria. The influence of these compounds on the risk of listeriosis in relation to product shelf life is discussed.

Argopecten irradians is one of the cultivated species of seafood in China. Frozen, dried, and vacuum-packaged scallops are the main processed forms of this species. Due to their high moisture content, vacuum-packaged scallops are perishable during storage; thus, accurately predicting shelf life according to the storage environment is particularly important for the seafood industry. Vacuum-packaged instant scallops stored at 20, 25, 30, 35, and 40 °C were used in the current study. Total volatile base nitrogen (TVB-N), pH, water activity, color, hardness, and microbiological composition were ascertained during storage. Based on the 10-point hedonic scale, the shelf lives of instant scallops stored at 20, 25, 30, 35, and 40 °C were 96, 78, 60, 42, and 32 days, respectively. Using the Arrhenius equation, a mathematic model based on storage temperature, TVB-N, and storage time was established. The Ea and k0 values were 51 kJ/mol and 3.96 × 106. The model can be used to predict the shelf life for any given temperature-time profile.

Abstract Tomato quality is determined by metabolite content which is governed by post-harvest physiological changes. A 30-day full factorial experiment investigated pre-packaging, disinfection and storage temperatures on 18 different biochemical, microbiological, enzymatic and subjective quality attributes of tomato quality. Principal component analysis revealed associations among the variables such as PC1 (28.85%): coliform/enzymatic softening; PC2 (21.52%): free sugars/sweetness; and PC3 (18.20%): sucrose hydrolysis/microbial spoilage/defense metabolites. Discriminant analysis showed that some specific parameters were highly significant (P<0.001) in determining quality changes in relation to the washing procedures and storage temperature. The prominence of ascorbic acid was observed in the equations which discriminate mostly on the basis of microbial deterioration. Further works in this respect entail fine-tuning through model verification of the equations. Multivariate analysis techniques are, therefore, recommended in studies whereby understanding of the phenomenon driving the post-harvest system’s dynamics has to be understood through diverse interrelated metabolic parameters.
