Aceh noodle seasoning was made from red chili, red onion, garlic, cardamom, turmeric, ginger, cumin, candlenut, coriander and pepper. All ingredients were mashed and then sauteed in a frying pan with the addition of cooking oil. In the food industry it is necessary to determine the shelf life so the consumers know the quality of the product. Shelf life is the periode of a product from the production process until the product has decreased in quality or is not suitable to consumption. This research was conducted using a semi-empirical accelerated shelf-life testing method with the Arrhenius equation. The estimation of shelf life was determined through the quality change of Aceh noodle seasoning which packed with aluminum foil packaging and stored based on temperature factor (room temperature, 40o C, and 50o C). Each sample was analyzed of thiobarbituric acid test, flavour and descriptif test in duplicate. The results show that Aceh noodle seasoning shelf life based on the critical parameters  stored at room temperature (27-30oC) was 71 days, at 40oC was 49 days, and at 50oC was 35 days.

Sensory, physicochemical and microbiological changes in Moroccan cooked kosher sausages stored at 6°C and 25°C were monitored over 35 days. Kosher sausages were very prone to changes in microbial status, as a result of high pH and water activity-values (aw-values) after processing. After 3 days of storage at 25°C and 1 week at 6°C the microbial colonies increased distinctively. Sensory changes were only detectable after the seventh day at 25°C. At 6°C, these sausages kept their sensorial characteristics. Levels of total volatile basic nitrogen were lower in the kosher sausages at 6°C than in those kept at 25°C. Changes at 25°C affected the quality of kosher sausage and limited the shelf life. From these results it can be concluded that storage at 25°C (ambient temperature) for 3 days or at 6°C (chilling) for 7 days without sensory changes is possible.

An active packaging film (APF1) with releasing low concentration sulfur dioxide (SO2) was tested on quality of ‘vitis labruscana kyoho’ table grape. All samples were stored at 5°C and during the storage period the main quality parameters, weight loss, berries shatter, decay, firmness, total soluble solids content (TSS), total acid (TA, using the PH of grape juice instead of the TA ), Vitamin c (Vc) content were monitored and compared with the control sample unpacked in any film. Results demonstrated that APF1 could reduce water loss of table grapes, prevent it from pathogens infection. The results also showed that APF1 could greatly guarantee a long shelf life for grape. After storage 56 days (storage at 0~5°C), the water loss, berry firmness, TA and Vc content in grapes packaged in APF1 were slowly reduced, TSS was slight increased, percentage of shatter and decayed berries of grapes were 22% and 27%, respectively. The percentage of berries decay of grapes packaged in APF1 was reduced to 5% from 21% for control batches on 11th days. All unpackaged table grapes (control batches) were decayed after 28 days. APF1 would help to preserve quality and extend shelf life of table grapes.

The optimal conditions of pressure, time, and processing temperature required to eliminate Listeria monocytogenes Scott A and Salmonella typhimurium ATCC 13311 in fresh pork loin and the effect of these optimal conditions on quality and shelf life were determined. Twenty-five grams of fresh pork loin were inoculated with either of the two organisms and were subjected to pressures between 414 and 827 MPa at either 2 or 25°C for 30 min. The was determined to be 2.17 min for L. monocytogenes and the was determined to be 1.48 min for S. typhimurium. Samples subjected to a 6D process were evaluated by sensory and objective tests as well as for shelf life. These samples were found to be different (P < 0.05) from controls when evaluated after cooking by a triangle test of difference, but only when the pressure was applied at 2°C and not at 25°C. The descriptive analysis test showed that cooked samples treated at 25°C were not different (P > 0.05) from controls in flavor, juiciness, and firmness. Color, peak load, water-holding capacity, and moisture were not found to be different (P > 0.05) between samples treated at 25°C and controls when both were cooked. However, in the raw state, differences were found in the values for color parameters L and b. The level of psychrotrophs was 5.7 log CFU/g for samples treated at 25°C after 33 days of storage at 4°C, as compared with 7.0 log CFU/g for controls. The color and peak load (texture) did not change over the storage period (P > 0.05) in any of the samples. All samples spoiled in 5 days when stored at 25°C.

Today, the most significant challenge encountered by food manufacturers is degradation in the food quality during storage, which is countered by expensive packing, which causes enormous monetary and environmental costs. Edible packaging is a potential alternative for protecting food quality and improving shelf life by delaying microbial growth and providing moisture and gas barrier properties. For the first time, the current article reports the preparation of the new films from Ditriterpenoids and Secomeliacins isolated from Melia azedarach (Dharek) Azadirachta indica plants to protect the quality of fruits. After evaluating these films, their mechanical, specific respirational, coating crystal elongation, elastic, water vapor transmission rate (WVTR), film thickness, and nanoindentation test properties are applied to apple fruit for several storage periods: 0, 3, 6, 9 days. The fruits were evaluated for postharvest quality by screening several essential phytochemical, physiological responses under film coating and storage conditions. It was observed that prepared films were highly active during storage periods. Coated fruits showed improved quality due to the protection of the film, which lowered the transmission rate and enhanced the diffusion rate, followed by an increase in the shelf life. The coating crystals were higher in Film-5 and lower activity in untreated films. It was observed that the application of films through dipping was a simple technique at a laboratory scale, whereas extrusion and spraying were preferred on a commercial scale. The phytochemicals screening of treated fruits during the storage period showed that a maximum of eight important bioactive compounds were present in fruits after the treatment of films. It was resolved that new active films (1–5) were helpful in the effective maintenance of fruit quality and all essential compounds during storage periods. It was concluded that these films could be helpful for fruits growers and the processing industry to maintain fruit quality during the storage period as a new emerging technology.

The aim of the study was to assess changes in qualitative characteristics of selected dairy products that occur during their shelf life. The research covered 2% pasteurized drinking milk, 18% cream and semi-fat tvarog produced in 3 regional processing plants (A, B and C) and purchased in the local retail network. A total of 186 samples were taken, including 20 samples of each of the above products from plants A and B, and 22 samples of these products from plant C. The following parameters were determined: chemical composition, density, potential acidity (°SH), freezing point, and the number of Enterobacteriaceae in drinking milk; as well as the content of fat, protein and dry matter, potential acidity (°SH), and the number of β-glucuronidasepositive Escherichia coli in cream and tvarogs. The research showed that the dairy products available in the retail network generally met the requirements of Polish standards. Deviations from the standards were found in the fat content of drinking milk and cream compared to that declared by the manufacturer. On both measurement dates, the acidity of the products did not exceed the prescribed limits, which indicates that the quality of the products was maintained during the storage period. The assessment of microbiological quality showed that on both dates the limit of E. coli contamination was exceeded in tvarog samples from dairy C, which indicates an unsatisfactory microbiological quality of the production process in this plant and the need to take corrective actions in the field of production hygiene. Drinking milk and cream, on the other hand, met the legal requirements in terms of process hygiene.

`Redcort Cortland' and `Redmax' and `Summerland McIntosh' apples (Malus ×domestica Borkh.) were treated with 900 nL·L-1 of 1-methylcyclopropene (1-MCP) for 24 hours at 20 °C before storage and were kept at 3 °C in either a controlled atmosphere (CA) of 2 kPa O2 and <2.5 kPa CO2 or in an air (RA) environment for up to 9 months. After 4.5 months, half of the fruit were treated with a second 900 nL·L-1 1-MCP application in air at 3 °C for 24 hours and then returned to RA or CA storage. At harvest and following removal at 3, 6, and 9 months and a 7-day shelf life at 20 °C, fruit firmness, titratable acidity (TA) and soluble solids content (SSC) were measured, while internal ethylene concentrations (IEC) in the apple core were quantified after 1 day at 20 °C. Upon storage removal and following a 21-day shelf life at 20 °C, disorder incidence was evaluated. 1-MCP-treated apples, particularly those held in CA-storage, were more firm and had lower IEC than untreated fruit. Higher TA levels were maintained with 1-MCP in all three strains from both storages, while SSC was not affected. Following the 6- and/or 9-month removals, 1-MCP suppressed superficial scald development in all strains and reduced core browning and senescent breakdown in RA-stored `Redmax' and `Summerland' and senescent breakdown in RA-stored `Redcort'. 1-MCP generally maintained the quality of `Cortland' and `McIntosh' fruit held in CA and RA environments (particularly the former) to a higher degree than untreated apples over the 9-month storage period. A second midstorage application of 1-MCP at 3 °C did not improve poststorage fruit quality above a single, prestorage treatment.

The influence of the polyfunctional food additive "Magnetofood" on the yield, batching, shrinkage, as well as physicochemical, microbiological, organoleptic parameters of wheat–rye bread" Kharkiv Rodnichok " enriched with this additive was investigated. The introduction of the food additive "Magnetofood" helps to increase the biological value (the content of the microelement of Fe is increased by 3 mg / 100 g), the energy value (increases by 3 kcal / 100 g) and the storage period (grows by 12 hours) in the experimental bread samples " Kharkiv Rodnichok " compared with the control (wheat–rye bread "Darnitsky"). That is, the food supplement "Magnetofood" due to Fe2 + can be recommended as an antioxidant and a source of easily digestible iron and an anti–anemia agent. It has been experimentally established that the introduction of the polyfunctional food additive "Magnetofood" improves the yield and quality of wheat–rye bread. In addition, the quality of bread is influenced by the way of introduction of "Magnetofood": when introducing "Magnetofud" in the form of an oil suspension (CHI), the indices are 1–2% better than when adding the additive as a dry powder. It also follows from the data obtained that the physicochemical parameters of the experimental bread samples " Kharkiv Rodnichok " are improved in comparison with the control (Bread "Darnitsky") as follows: yield, bake, shrinkage, porosity of crumb are increased by 2–3%, 5–10 %, 5–10%, 3–6% respectively; and the crumb humidity and acidity decrease by 1% and 1.0– 1.5 °, respectively. Microbiological studies have shown that seeding Вас. subtilis after 10 days will increase: in control 2 times, and in the samples of bread "Kharkov fontanel" 1, 2 – in 1,3 times. That is, "Magnetofood" has an antimicrobial effect, which leads to better quality, preservation of freshness and lengthening the shelf life of bakery products. Thus, the introduction of the polyfunctional food additive "Magnetofood" in wheat–rye bread improves yield, quality and shelf life.
