\nshelf-life stability of Thai-style fried rice crackers, known as “nang led”, or, “kawtan” in
\nthe north of the country. Two types of packaging materials; white co-extrusion oriented
\npolypropylene and linear low density polyethylene (OPP/LLDPE) plastic bag and
\nlaminated multilayer metalized (MET) plastic bag were employed. Four conditions; none,
\noxygen absorber, desiccant and the combination of oxygen absorber and desiccant were
\nused. Eight packaging systems were compared to the traditional packaging using
\ntransparent OPP. After four months the results indicated that peroxide value, conjugated
\ndienes and conjugated trienes were increased and corresponded with the value of TBARS
\nand carbonyl compounds. This also indicated and crackers packed in transparent OPP
\nwere rancid, while the crackers in other packaging conditions had a lower level of
\nrancidity. The physical properties in terms of water activity and moisture contents were
\nslightly changed and related to the crispiness of the crackers. The crackers packed in a
\nmetallic bag with oxygen absorber and desiccant had the best crispiness. The criteria used
\nfor measuring rancidity correlated well with quantitative descriptive analysis (QDA)
\nperformed by ten trained panelists during storage. The oxidative rancidity measurement
\nand sensory evaluation showed that the sample packed in traditional packaging had strong
\nrancid flavour, while the crackers in the other eight packaging systems were still
\nacceptable to the panelists. The best packaging condition resulting from this study is the
\nmetallic bag with oxygen absorber and desiccant, because it showed the highest crispiness
\nand the lowest chemical change, especially the increase of carbonyl compounds. \";s:5:\"thumb\";s:101:\"images/t/41/effect-of-packaging-systems-on-shelf-life-stability-of-thai-style-fried-rice-crackers.jpg\";s:6:\"thumb2\";s:102:\"images/t2/41/effect-of-packaging-systems-on-shelf-life-stability-of-thai-style-fried-rice-crackers.jpg\";s:9:\"permalink\";s:85:\"effect-of-packaging-systems-on-shelf-life-stability-of-thai-style-fried-rice-crackers\";s:5:\"pages\";s:1:\"9\";s:6:\"rating\";s:3:\"2.5\";s:5:\"voter\";s:1:\"4\";}i:1;O:8:\"stdClass\":13:{s:2:\"id\";s:4:\"3758\";s:6:\"status\";s:8:\"verified\";s:11:\"author_name\";s:6:\"shinta\";s:9:\"author_id\";s:3:\"377\";s:14:\"author_website\";s:0:\"\";s:5:\"title\";s:74:\"Numerical Investigation of the Chilling of Food Products by Air-Mist Spray\";s:11:\"description\";s:1243:\"Spray chilling using air-mist nozzles has received
\nmuch attention in the food processing industry because of the
\nbenefits it has shown over forced air convection. These benefits
\ninclude an increase in the heat transfer coefficient and a reduction in
\nthe water loss by the product during cooling. However, few studies
\nhave simulated the heat transfer and aerodynamics phenomena of the
\nair-mist chilling process for optimal operating conditions. The study
\nprovides insight into the optimal conditions for spray impaction, heat
\ntransfer efficiency and control of surface flooding. A computational
\nfluid dynamics model using a two-phase flow composed of water
\ndroplets injected with air is developed to simulate the air-mist
\nchilling of food products. The model takes into consideration
\ndroplet-to-surface interaction, water-film accumulation and surface
\nrunoff. The results of this study lead to a better understanding of the
\nheat transfer enhancement, water conservation, and to a clear
\ndirection for the optimal design of air-mist chilling systems that can
\nbe used in commercial applications in the food and meat processing
\nindustries.

\nPersimmon (Diospyros kaki Thunb.) fruit were harvested at the commercial maturity (orange color) and then
\ntreated with 1 -methylcyclopropene (1 -MCP) at three doses (0.5, 1 and 1.5 ul L_1) for 24 h at 20°C and kept at
\nambient air temperature (20°C) for shelf life evaluation. The non-1 -MCP treated fruit softened within 15 days
\nafter harvest, resulting in unacceptable quality. The 1 -MCP treatments at more than 0.5 ul L_1 inhibited fruit
\nsoftening for 30 days after harvest in association with suppression of respiration at room temperature.
\nTreatment with 0.5 ul L_1 1-MCP had a limited inhibitory effect on softening. Change in soluble solid content,
\nacid and peel color occurred during storage, but all these processes were significantly delayed by 1-MCP
\ntreatment. These results indicated that 1 -MCP is an effective tool for quality improvement and extension of shelf

\nand incubated to ripen them. While the fruit are widely marketed (mostly in informal markets), household utilisatio
\nand marketing are limited by a short shelf life of about 3 days for ripe fruit. To investigate ways to increase the

\nC), at ambient room
\ntemperature (30
\no
\nC), or in clay pots (31
\no
\nC), on the subsequent softening of the fruit after removal from storage. T
\neffect of keeping ripe fruit on open plates, in polyethylene bags and clay pots, all at ambient room temperature, on
\nweight loss, skin and pulp colour, and soluble solids concentration (SSC) was also evaluated. Overall, unripe fruits
\nunder cold storage lost less weight and their softening was delayed, thus extending their storage life. In contrast,
\nstoring fruit in clay pots advanced and enhanced their softening and subsequent deterioration. Ripe fruit kept in
\npolyethylene bags lost 10 % of initial fresh weight over a 6 day storage period compared with 29% for fruit on op
\nplates and 22% in clay pots. Storing ripe fruit in polyethylene bags maintained a higher proportion (78%) of fruit
\nwith a skin colour rating of fair and good (combined) compared with only 28% and 35% of the fruit from plates an
\nclay pots, respectively. The remaining fruit developed a darkened dull skin colour. In addition, 34% of the fruit from
\npolyethylene bags still had the desirable orange pulp colour on day 6, compared with only 4% and 0% for plates and
\nclay pots respectively. The SSC were highest in ripe fruit kept on plates and clay pots compared with polyethylene
\nbags, probably as a result of the concentration effects associated with water loss from fruit. The study has
\ndemonstrated the potential for low temperature storage and using polyethylene packaging to lengthen stora
\nshelf life of fresh U. kirkiana fruit, but the possible risk of chilling injury at these low storage temperatures needs t
\nbe evaluated. \";s:5:\"thumb\";s:118:\"images/t/35/lengthening-storage-and-shelf-life-of-uapaca-kirkiana-muell-arg-an-indigenous-fruit-to-parts-of-africa.jpg\";s:6:\"thumb2\";s:119:\"images/t2/35/lengthening-storage-and-shelf-life-of-uapaca-kirkiana-muell-arg-an-indigenous-fruit-to-parts-of-africa.jpg\";s:9:\"permalink\";s:102:\"lengthening-storage-and-shelf-life-of-uapaca-kirkiana-muell-arg-an-indigenous-fruit-to-parts-of-africa\";s:5:\"pages\";s:1:\"8\";s:6:\"rating\";s:1:\"0\";s:5:\"voter\";s:1:\"0\";}i:7;O:8:\"stdClass\":13:{s:2:\"id\";s:4:\"3504\";s:6:\"status\";s:8:\"verified\";s:11:\"author_name\";s:6:\"shinta\";s:9:\"author_id\";s:3:\"377\";s:14:\"author_website\";s:0:\"\";s:5:\"title\";s:71:\"Colour change of apple as a result of storage, shelf-life, and bruising\";s:11:\"description\";s:1326:\"Two apple cultivars (Champion and Jonagold)
