Comparative effects on storage period of varieties Pineapple fruits

Pineapple is considered as one of the most wanted tropical fruits and it is widely taken for fresh consumption as well as their flesh and juice are used for preparation of different product in Agro-processing industries. For such industrial processes, it is important to know the information of characteristics changes of pineapple during day after storage. Four varieties of pineapple were collected from different areas of Bangladesh named Honey Queen (H.Q), Giant Kew (G.K), Asshini and Ghorasal. Some Physico-chemical properties (weight loss, moisture content, ash and edible portion, pH, TSS, titrable acidity (TA), total sugar, reducing sugar) biochemical properties (ascorbic acid) and sensorial attributes (color, odor, firmness, appearances, sweetness and overall acceptability) of pineapple juice were studied during day after storage. This study examined the Comparison of different varieties of pineapple fruit characteristics and sensory quality of the pineapple fruits during storage. It was shown that there was a significant changes between the storage periods in relation to different varieties of fruits. The firmness of pineapple fruits were in outside and inside to be 0.21 to 0.27 N/m2 and 0.06 to 0.10 N/m2, respectively. The pH values of different varieties were found to be in the range of 4.30 to 4.36. The highest and lowest sweetness index were estimated to be 36.30 and 22.15 for Honey Queen and Asshini respectively. The highest and lowest magnitude of sugar contents of four pineapple varieties were found to be in the range of 14.16 to 15.8 mg/100g.The average TSS values were found to be 15.12%, 12.33%, 13.14% and 12.95% for H.Q., G.K., Asshini and Ghorashal, respectively.

Fruit juices are common man’s beverages and sold at public places. Since they are known for carrying heavy microbial load, the present investigation was undertaken to enumerate and identify the microorganisms in fruit juices (sweet lime, orange and pineapple) selected from three different street vended shops (source A, B and C) in Mysore. The juices were analyzed for the microbial quality for type of organisms and number of colonies by serial dilution technique, pour plate method,gram’s staining method and staining for fungi; and physico-chemical properties. Results showed that the pineapple juice from two sources was highly contaminated with bacterial pathogens (25×104CFU/mland 20×104CFU/ml). All samples were contaminated with faecal streptococci. In source-B and C, all juices showed high counts of fungal colonies (Aspergillus, Penicillium, Fusarium and yeast). It is contended that contamination was mainly due to poor quality of water used for dilution as well as prevailing unhygienic conditions related to washing of utensils and maintenance of the premises. The result showed the poor hygienic quality of street vended fruit juices and the possible risk to the consumers. DOI: http://dx.doi.org/10.3126/jfstn.v8i0.11746 J. Food Sci. Technol.

The fresh mushroom and mushroom powder were analysed for their composition. Mushroom powder was incorporated in the formulations of cake at 0, 5, 10, 15 and 20% by weight. The effect of various levels of mushroom powder on the physico-chemical properties and nutritional quality of cakes had been observed. Mushroom powder at 15% addition level significantly improved colour, flavour and texture of cake. Cakes were also prepared by incorporating various levels (0-20%) of mushroom powder in plane cake formulations to evaluate optimum level of powder addition. It was observed that in achieving acceptable cake quality, in terms of volume significantly higher amount (10-15%) of mushroom powder could be incorporated in cake formulations. Compositional analysis of cake showed that cake containing mushroom powder had higher protein and fat content and lower carbohydrate content than the control cake. The cakes containing various levels of mushroom powder were evaluated for their sensory attributes by a panel of 10 tasters. The results revealed that the colour and flavour of cake containing mushroom powder was significantly different from the control cake. The texture of the cakes with mushroom powder was equally acceptable to the control cake. The overall acceptability of the cakes with mushroom powder was equally acceptable to the control cake.DOI: http://dx.doi.org/10.3329/pa.v21i1-2.16769 Progress. Agric. 21(1 & 2): 205 - 214, 2010

Sunflower seeds are highly popular in food mixes, especially biscuits and are thought to be nutritionally beneficial. These seeds are rich in healthy fats, useful plant compounds and many vitamins and minerals. The present study was conducted to investigate the effect of the incorporation of irradiated sunflower flour on the physico-chemical and sensory properties of biscuits during the storage period. The physical and chemical properties of wheat flour with 72% extraction, nonirradiated sunflower flour and sunflower flour irradiated with 5 kGy and 10 kGy were estimated. Additionally, the physical, chemical and sensory properties of extracted oils from the biscuits were also evaluated during storage periods of two and four months. The refractive index, peroxide value and iodine value decreased as the storage period increased, while acids such as oleic acid and the acid value increased slowly and gradually. Additionally, the fatty acids of the oils extracted from biscuits during storage were high in unsaturated fatty acids at the beginning of storage. After two and four months of storage, an increase in saturated fatty acids and a decrease in unsaturated fatty acids was observed. The results showed that the overall acceptability of sunflower flour biscuits irradiated at a dose of 10 kGy was highest, while the control biscuits had the lowest acceptability after 4 months of storage. It was concluded that the substitution of up to 10% of wheat flour with nonirradiated or irradiated sunflower flour can be a good method for food product development due to the ability of sunflower flour to improve the nutritional value and overall acceptability of biscuits.

Cold storage of peach fruit at low temperatures may induce chilling injury (CI). Pre-storage 1-MCP and high CO2 treatments were reported among the methods to ameliorate CI and reduce softening of peach fruit. However, molecular data indicating the changes associated with pre-storage 1-MCP and high CO2 treatments during cold storage of peach fruit are insufficient. In this study, a comparative analysis of the difference in gene expression and physico-chemical properties of fruit at commercial harvest vs. stored fruit for 12 days at 0 °C (cold-stored (CS), pre-storage 1-MCP+CS, and pre-storage high CO2+CS) were used to evaluate the variation among treatments. Several genes were differentially expressed in 1-MCP+CS- and CO2+CS-treated fruits as compared to CS. Moreover, the physico-chemical and sensory data indicated that 1-MCP+CS and CO2+CS suppressed CI and delayed ripening than the CS, which could lead to a longer storage period. We also identified the list of genes that were expressed commonly and exclusively in the fruit treated by 1-MCP+CS and CO2+CS and compared them to the fruit quality parameters. An attempt was also made to identify and categorize genes related to softening, physiological changes, and other ripening-related changes. Furthermore, the transcript levels of 12 selected representative genes from the differentially expressed genes (DEGs) in the transcriptome analysis were confirmed via quantitative real-time PCR (qRT-PCR). These results add information on the molecular mechanisms of the pre-storage treatments during cold storage of peach fruit. Understanding the genetic response of susceptible cultivars such as ‘Madoka’ to CI-reducing pre-storage treatments would help breeders release CI-resistant cultivars and could help postharvest technologists to develop more CI-reducing technologies.
