Ber, a climacteric fruit crop, is liable to spoilage during storage. This study aims to evaluate the effect of coatings on shelf life and quality retention in ber under ambient storage conditions. Coated and uncoated ber fruits were stored at ambient storage temperatures (±25ºC) for 10 days and accessed every 2 days for analysis. Ber fruits reported minimum weight loss (2.68g), PLW (14.35%) and TSS (9.52%) with the application of petroleum jelly coating. Minimum total sugars (8.98%), minimum reducing sugar content (3.96%), maximum non-reducing sugars (5.69%) and maximum antioxidant activity (63.83%) was recorded in fruits with petroleum jelly coating. This study highlights the importance of coating of fruits for enhanced shelf life and quality retention under ambient storage conditions.

Freshly harvested capsicum has limited shelf life (5-6 days) under ambient storage conditions. The functional quality of capsicum has been assessed in two sizes (300g±10%) and (900g±10%) of 30µ flex freshTM expanded polyethylene biopolymer pouches at 3 and 10oC and 90-95% RH under modified atmospheric storage. In both small and big size pouches, composition of oxygen and carbon dioxide varied from 18.8-19.9% and 18.8-19.4% and from 2.2-0.7% and 2.0-1.4%, respectively during 28 days of storage at 3oC. Positive and significant correlation was observed between overall acceptability and CO2 composition however, negative correlation was observed with O2 composition. Minimum increase (6.02% and 4.35%) in PLW, minimum decrease in firmness (4.71N-3.50N and 4.71N-2.70N), minimum decrease in chlorophyll (70.3% and 75.5%) and minimum losses (47.6% and 40.3%) of ascorbic acid were obtained after 28 days of storage in small and big size capsicum, respectively at 3oC. The decrease in total phenol and antioxidant activity was 82.4% and 78.6% and 60.1% and 59.4%, respectively after 28 days of the storage at 3oC of small and big size capsicum, respectively. Judges observed most acceptable consistency and OAA score for both sizes of capsicum in pouches up to 21 days of storage at 3oC.

The use of distillers' dried yeast as inoculum for rum fermentations was studied on a pilot plant scale. Two fermentation procedures (batch and fed batch) and four levels of dry yeast (0.5, 1.0, 1.5 and 2.0 g/L) were tested. The fermentations were followed for 36 hours. Product yields at 24 hours and 36 hours were determined. The resultant fermentation rate was below the rate required by the local industry (close to completion after 30 hours). This drawback is further complicated by the fact that dried yeast is not stable and has a shelf life that can vary from 1 to 12 months, depending on ambient storage conditions.

Seeds of Impatiens hainanensis were stored in three different environments: ambient (25°C, 70-80% RH), dry (25°C, 2-5% RH) and cold (4°C, 40-50% RH). The seeds maintained their germination for 90 days in the three storage conditions, albeit at relatively low levels, particularly for seeds in cold storage. Seed vigour was maintained for 45 days for seeds in cold storage, 60 days for seeds in ambient storage, and 90 days for seeds in dry storage. A moisture content around 3.8% is suggested as appropriate for the storage of I. hainanensis seeds. During storage (up to 90 days) under ambient and cold storage conditions, soluble sugar content, SOD and CAT activity all decreased, and were lower than seeds in dry storage. Relative conductivity and TBARS content both increased during ambient and cold storage and were higher than seeds in dry storage after the same storage period. Dry storage better maintained the antioxidant enzyme system of I. hainanensis seeds.

<div><p><em>Present study was conducted to investigate the effect of gamma radiations on the quality and shelf life of strawberries. The aim of this study was to evaluate gamma radiation doses in  range of 0.3- 1.5 kGy. The irradiated strawberries were stored in ambient (temperature 25 +- 2<sup>o</sup>C, RH 70 %) and refrigerated (3 +-1<sup>o</sup>C, RH 80%) conditions. In samples treated with dose 1.2-1.5 kGy no decay was recorded up to 9 days of ambient conditions. Under refrigerated conditions, strawberry samples of unirradiated and irradiated in the range of 0.3-0.9 kGy started decaying after 14 days of storage. No decay was observed in the samples treated with 1.2-1.5 kGy up to 28 days of refrigerated storage. Dose of 1.2 kGy was significantly effective in reducing the weight loss and in maintaining the higher overall acceptability under both the storage conditions compared to the other treatments. This dose also proved effective in retention of significantly higher levels of total sugars compared to the other treatments. Thus, it was established that irradiating strawberries with dose of 1.2 kGy can prove beneficial in facilitating the marketing of the fruit to distant places other than the local markets, thereby benefiting the growers.</em></p></div>

Nutritional Benefits

The apple is a climacteric fruit, characterized by having a long post-harvest life in optimal storage conditions, in addition to various nutritional benefits. In Mexico, it has become common to sell apple by piece and ready to be consumed, each piece after being washed and disinfected, is protected with a polyurethane net and a low-density polyethylene plastic film, which contributes to the increase in the generation of solid waste and environmental pollution. The main objective of this work was to evaluate the effectiveness of edible films based on chayotextle starch and pectin with nopal mucilage, to preserve the physicochemical, microbiological and sensory characteristics of apples stored in refrigeration (4-6°C). Two types of films were made: T1: chayotextle starch (4%), glycerol (2%); T2: pectin (1%), nopal mucilage (0.5%), glycerol (30% w / v); These were determined the permeability to water vapor (T1: 1.317x10-12; T2: 8.854 g s- 1 Pa-1 m -1) and oxygen permeability (T1: 4.444x10-14, T2: 5.87 gm s -1 Pa-1 m-2). The shelf-life study in apples showed that both the edible films and the plastic material maintained the physicochemical (pH), sensory, rheological (Hardness) and microbiological (fungi and yeast, mesophilic aerobic and total coliform) characteristics of the apples for 40 days

The study tends to study the postharvest technological evaluation of different tomato storage environments/media for domestic preservation of fresh and fleshy tomato quality to improve its shelf life with emphasis on charcoal cooler storage bin (CCB). It involved the preliminary investigation of farmers’ knowledge and skill with regard to tomato preservation and storage with different tomato storage environments, adoption of developed CCB: design capacity was 40kg/batch storage for 7days in Nsukka. These were conducted between April to September, 2019. The field studies were carried out through structured questionnaire to know the adaptive knowledge and skill of farmers with regard to tomato preservation and storage. Comparative study of the developed CCB with other environmental storage conditions namely: open-air (ambient) storage (OAS), refrigerator (RF), freezer (FR), (room) laboratory storage (LS), and thatched house storage (THS) were carried out. The four varieties of fresh and fleshy harvested tomato fruits: Copra, Nindo F1, Yolings, and UTC locally cultivated were set into the 6 treatments (media), each treatment was replicated twice. The study showed that the quality attributes such as cracking, yellowing, weight loss, rottening, hardness, and brix value were determined. Based on the physicomechanical parameters of the tomatoes under seven days investigation, FR (0 °C,95%) and RF (10 °C, 85%) had better quality and prolonged shelf life, followed closely by the tomato CCB storage (12 °C,85%) and THS(12 °C,78%) then LS(25 °C,78%) and OAS(30 °C,78%). FR storage inhibited/delayed (cold stress) ripening with minimum weight loss, as compared to the other treatments in terms of stability in all parameters. Similarly, CCB was close to RF storage and performed significantly better than ambient OAS and LS. OAS and LS exhibited higher weight loss, and rapid ripening to deterioration due to tropical temperature and relative humidity fluctuation. Therefore, CCB is recommended for rural small scale farmers.

Stability Data

Extemporaneous oral liquid preparations are commonly used when there is no commercially available dosage form for adjustable dosing. In most cases, there is a lack of stability data to allow for an accurately assigned shelf life and storage conditions to give greater confidence of product safety and efficacy over its shelf life. The aim of this study was to evaluate the physical, chemical and microbiological stability of an extemporaneous oral liquid suspension of losartan potassium, 5 mg/mL, used to treat paediatric hypertension in Our Lady’s Children’s Hospital Crumlin, Ireland. The losartan content of extemporaneous oral suspensions, prepared with and without addition of water, was measured by UV and confirmed by HPLC analysis. Suspensions were stored at 4 °C and room temperature (RT) and were monitored for changes in; pH, colour, odour, re-dispersibility, Total Aerobic Microbial Count, Total Yeast and Mould Count and absence of E. coli. Results showed that suspensions prepared by both methods, stored at 4 °C and RT, were physically and microbiologically stable over 28 days. Initial losartan content of all suspensions was lower than expected at 80–81% and did not change significantly over the 28 days. HPLC and NMR did not detect degradation of losartan in the samples. Suspensions prepared in water showed 100% losartan content. The reduced initial losartan content was confirmed by HPLC and was related to the acidic pH of the suspension vehicle. Physiochemical properties of the drug are important factors for consideration in the selection of suspension vehicle for extemporaneous compounding of oral suspensions as they can influence the quality, homogeneity and efficacy of these preparations.
