In India, various types of unexplored edible flowers are being utilized traditionally as food and medicine by the rural communities since ancient time only during their flowering time due to short post harvest life. These flowers are rich in phytochemical (e.g. polyphenolics, anthocyanins) which possess numerous health benefits. So, the present investigations were conducted to develop a spiced beverage/appetizer (spiced squash) from rhododendron flower petals and its quality evaluation during storage. Different combinations of petals extract and total soluble solids (TSS) were tried to standardize proper combination for spiced beverage. Appetizer recipe (T3) prepared with 35% extract, 40°B TSS and 1.20% acid was found to be best based on quality characteristics of the product. The best-selected appetizer recipe was packed in glass and PET bottles and stored for 6 months under ambient (15-25°C) and refrigerated temperature conditions (4-7°C). Overall effect of packaging and storage revealed that various quality characteristics like TSS, apparent viscosity, reducing and total sugars of appetizer increased slightly, whereas, other chemical characteristics like acidity, ascorbic acid, anthocyanins, total phenols and sensory characteristics scores of colour, body, taste, aroma, overall acceptability score decreased slightly during storage. The quality of beverage was retained better in glass bottles under refrigerated condition as compare to ambient storage condition.

The objective of this work was to compare the effects of four different concentrations of cassava starch film and storage temperature on shelf life and the quality of a genotype of acerola from the Germplasm Active Bank (GAB) of Federal Rural University of Pernambuco, Brazil. Sound orange-reddish acerola fruits were washed with a chlorine solution (100 mg.L-1 active chlorine) and randomly distributed into different lots. The fruits were dipped for 3 min in a cassava starch suspension with concentrations of 1, 2, 3 and 4% (w/v) and the control without coating, stored at 10ºC (85% RH) and 22ºC (85% RH). The total soluble solids (TSS), pH, titratable acidity (TA) and ascorbic acid (AA) were determined at harvest and regular interval during storage. The use of cassava biofilm at 1% on acerola fruits maintained the highest ascorbic acid content and the temperature of 10ºC extended storage life. The fruits coated with 1 and 2% biofilm could be stored for a period up to 15 days at 10ºC, with acceptable quality characteristics.

Carrot (Daucus carota L) is a carotenoids rich vegetable which is mainly consumed raw, converted to various products and cooked vegetable dishes. Present studies were carried out to study the changes observed in quality characteristics of dried carrot roundels during storage. Steam blanching and KMS dipping of carrot roundels followed by mechanical cabinet drying was found to be the best pretreatment for drying of carrot roundels as discussed earlier. These dried carrot roundels were further packed and stored under refrigerated (4-7°C) and ambient (11.6-26.2°C) storage conditions for 12 months. The dried carrot roundels packed in aluminium laminated pouches and stored under refrigerated conditions showed minimum increase in physico-chemical characteristics like moisture content (11.03%), water activity (0.310), pH (6.04), reducing sugars (21.00%), total sugars (35.36%) and retained highest amounts of titratable acidity (0.73%), carotenoids (29.40mg/100g), total phenols (87.50mg/100g), crude fibres (4.16%), rehydration ratio (7.81), antioxidant activity (52.68%) and SO2 content (174.75 ppm), respectively. The sensory characteristics scores like colour (8.05), texture (7.48), taste (6.88) and overall acceptability (7.54), respectively were also retained highest in the aluminium laminated pouch under refrigerated storage condition.

The effect of different composite coatings on quality of semi-moist apricot cubes mixed with cornflakes was investigated during 180 days of storage. The apricot cubes were osmotically dehydrated (OD) and coated before hot-air drying (HAD) at 60 °C. Chitosan-bees wax (CBW) and whey protein isolate-bees wax-oleic acid (WPI-BW-OA) coatings were applied after HAD and the samples were added to cornflakes. Application of OD and pectin-ascorbic acid (Pec-AA) coating (prior to HAD) and WPI-BW-OA coating (after HAD) led to significant retention of total phenol compounds, β-carotene and antioxidant activity in apricot cubes compared to uncoated and CBW-coated samples. WPI-BW-OA-coated samples gave significantly higher L* values (lighter color) and b* values (more creamy or yellowish color) and lower a* values (less reddish color) and browning values than control followed by CBW-coated apricots at any time of storage (p < 0.05). The rate of apricot moisture loss and cornflakes moisture gain was higher in uncoated apricot cubes, followed by CBW- and WPI-BW-OA-coated samples. Application of WPI-BW-OA coating was effective in retaining the crispness measured by lower firmness (Fmax) values in cornflakes upon storage. Based on the obtained results, WPI-BW-OA coating allowed effectively preserving the quality characteristics of semi-moist apricot cubes and cornflakes components in the mixed state.

The benefits conferred by a prestorage heat treatment on poststorage quality of apples (Malus domestics Borkh.) were measured on `Anna', a non-storing early cultivar, and `Granny Smith', a long-storing late cultivar. The major benefit was a decrease in rate of apple softening, both during OC storage and during simulated shelf life at 20C. Soluble solids concentration was not affected by heat treatment, but titratable acidity was reduced. Ethylene production after heat treatment and storage was similar to or higher than that of control apples, but respiration was lower. The optimum temperature and time combination for prestorage treatment of both cultivars was 4 days at 38C.

Abstract Fruits and vegetables are important sources of nutrients for mankind. Among the various fruits available in Bangladesh, mango occupies a vital place in the human nutrition for its delicious taste and higher nutritious value. In this study, five mango varieties, viz. Fazli, Amrupali, Langra, Gopalbogh and Misribogh, were tested to evaluate the quality of these mango varieties available in Northern Bangladesh. Physiochemical characteristics, including moisture, ash, total carbohydrates, total solids, total soluble solids (TSS), pH, acidity, total sugars and ascorbic acid contents were evaluated. The results showed that there were significant (p< 0.05) differences among mangoes of all varieties for physicochemical parameters. In case of proximate composition, the mango variety Amrupali showed the highest ash content (2.34±0.15) and fat content (1.18±0.13). Protein content (0.94±0.12) and total fiber (2.67%) content was shown to be the highest by Gopalbogh and Misribogh, respectively. The selected mango varieties contained TSS of 12.87~20.55oBrix, pH of 4.45~4.67, titrable acidity of 0.07~0.42%, reducing sugar of 8.40~15.43%, non-reducing sugar of 9.24~10.48%, and total sugarof 18.88~25.12%. The study findings would be helpful for the consumers, dietitian and industry policymakers.

AbstractSixty crossbred (Large White × Landrace × Duroc) pigs were used to compare the growth performance, carcass and pork quality characteristics of entire, surgically castrated and immunologically castrated male pigs from two Western Australian commercial genotypes (genotype A : ‘lean’ genotype and genotype B : propensity for increased subcutaneous fat deposition). Pigs from genotype B had a higher average daily gain and a superior food conversion ratio compared with pigs from genotype A. Entire males had lower backfat compared with surgically and immunologically castrated male pigs. Pork from entire males was drier, tougher and had lower overall acceptability scores compared with surgically or immunologically castrated male pigs. Pork from genotype A pigs had a lower m. longissimus thoracis (LT) ultimate pH and higher drip loss compared with pork from genotype B pigs. However, consumer taste panel assessment indicated that pork from genotype A pigs was more tender, had higher juiciness and overall acceptability scores compared with pork from genotype B pigs. Within genotype A, the consumer taste panel preferred pork from surgically castrated pigs compared with either entire or immunologically castrated pigs. Within genotype B, the consumer taste panel preferred pork from immunologically castrated pigs compared with either entire or surgically castrated male pigs. These results indicate that interactions between genotype and castration method can significantly influence eating quality of pork.
