A study on the effect of different packaging materials and storage conditions was carried out on keeping quality of freshly prepared bleached lac packaged in five different types of packaging materials: Low Density Poly Ethylene (LDPE ), High Density Poly Ethylene (HDPE), Poly Propylene (PP), Metalized Polypropylene film (METPP) and five layer craft Paper Bag (PG). The samples were stored in both ambient and refrigerated conditions (14-160C) and quality parameters were evaluated at quarterly interval after 3, 6, 9 and 12 months of storage followed by comparison with samples stored in open condition. For storage under ambient condition in room, the flow value (fluidity), life (heat polymerization time) and acid value (AV) of the packaging material was highest for metalized film bag i.e.10mm, 5 min. and 70.69 respectively and impurity content was least (2%) after 3 months of storage due to high amount of moisture (4.12% db) retained in the sample. These parameters were lower in other packaging materials due to lower moisture content (1.38-2.40% db) with the lowest value (1.01% db) in open storage condition. For storage under the refrigerated condition, these parameters were higher compared to ambient storage for all packaging material. Flow value, life and acid value of samples in the metalized bag were highest; 35mm, 10 min. and 74.36 after 3 months of storage. However, these parameters were lower in others packaging materials due lower moisture content (1.50-2.61% db) with lowest value (1.23% db) in open storage condition. The flow and life of samples packaged in metalized film bag were highest i.e. 25mm and 5 minutes respectively after six months of storage as compared to when packaged in others. During the study it was observed that keeping quality of bleached lac samples was better in metalized film bag (82.5µ) compared to other packaging materials for both ambient and refrigerated storage condition.

Background: Pro-vitamin A carotenoid (pVAC) rich foods are those foods that contain substance which can be converted within the human body into retinol. These foods also contribute to the reduction of vitamin A deficiency diseases. Yellow-seeded maize flour is a pVAC rich food. Identifying the right packaging materials and storage conditions that retain pVAC in this food is essential for their health benefits. Traditionally, maize flour is stored with different packaging materials to increase its shelf life. For example, previous studies have shown how during storage in different food matrices, carotenoids, including maize grains, are highly susceptible to degradation by temperature, light, and oxygen. Therefore, in this study we investigated the effect of storage packaging materials (polypropylene woven sacks-PWS, high-density polyethylene bags-HDPE, and polyvinyl plastic containers-PPC) and storage condition (temperature and relative humidity) on retaining pVAC in yellow-seed maize flour.Methods: The yellow-seeded maize grains were collected and ground into flour. The maize flour was divided into portions (200 g). Each portion was packed and sealed in PWS, HDPE, and PPC. The control samples (12 pieces) were stored on top of the storage box. The packed samples were stored in both the upper (12 samples) and lower (12 samples) compartment of a storage wooden box. The interior of the upper part was lightened with aluminum foil and fitted with fluorescent tube to increase the light intensity. The lower compartment was darkened with gloss black painting. The flour samples were stored for 28 days. Samples were collected for pVAC and xanthophylls analyses at 7 day intervals using standard methods.Results: The results demonstrated how packaging in PPC and storing in a dark compartment resulted in the highest total pVAC (92.39%) and total xanthophylls (89.44%) retention and retinol equivalent (RE) (0.40 µg/g). In contrast, packaging in HDPE and storing in lighted compartment resulted in the lowest pVAC (44.92%) and total xanthophylls (46.76%) retention and RE (0.19 µg/g).Conclusions: Packaging yellow-seeded maize flour in PPC and storing in the dark may be recommended for maximum retention of carotenoids in yellow-seeded maize flour since, as the packaging material and storage condition resulted in the highest pVAC retention and retinol equivalent.Keywords: Yellow-seeded maize; Carotenoids; Packaging materials; Storage conditions; Retinol equivalent

Extracts from eleven different plant species such as jute (Corchorus capsularisL.), cheerota (Swertia chiraitaHam.), chatim (Alstonia scholarisL.), mander (Erythrina variegata), bael (Aegle marmelosL.), marigold (Tagetes erecta), onion (Allium cepa), garlic (Allium sativumL.), neem (Azadiracta indica), lime (Citrus aurantifolia), and turmeric (Curcuma longaL.) were tested for antibacterial activity against potato soft rot bacteria,E. carotovorasubsp.carotovora (Ecc)P-138, underin vitroand storage conditions. Previously,EccP-138 was identified as the most aggressive soft rot bacterium in Bangladeshi potatoes. Of the 11 different plant extracts, only extracts from dried jute leaves and cheerota significantly inhibited growth ofEccP-138in vitro. Finally, both plant extracts were tested to control the soft rot disease of potato tuber under storage conditions. In a 22-week storage condition, the treated potatoes were significantly more protected against the soft rot infection than those of untreated samples in terms of infection rate and weight loss. The jute leaf extracts showed more pronounced inhibitory effects onEcc-138 growth both inin vitroand storage experiments.

Potato microtubers plays important role in seed potato production technology as it has great advantage of storage, transport and mechanization due to their little size and reduced weight. Dormancy in potato microtubers is very important and storage conditions as well as size of microtubers influences the dormancy in microtubers. Increasing size of the micro-tuber resulted in significant increase in the viability and sprouting ability of microtubers with reduced durations of dormancy and weight loss at the end of storage. Small microtubers are more vulnerable to storage damage. The larger microtubers lost moisture content more slowly and retained firmness longer when stored at 40C. Development of dormancy during storage strongly affected by the storage condition especially the temperature regime, the presence of light and the relative humidity. The dormancy duration was linearly and inversely correlated with the length of storage. Storage containers and conditions are also important for microtuber storage. Endogenous hormones ABA, ethylene, cyokinin and gibberllic acid play a significant role in tuber dormancy regulation.Microtubers with thick diameter which have passed more times in dormancy and have better functionality than small microtubers with less time in dormancy. Growth regulators like gibberellic acid, thiourea, gibberllic acid + thiourea, randite and carbon disulphide plays significant role in dormancy breaking of microtubers.

Abstract Feed ingredients and additives could be a potential medium for foreign animal disease entry into the United States. The feed industry has taken active steps to reduce the risk of pathogen entry through ingredients. Medium chain fatty acid (MCFA) and heat pulse treatment could be an opportunity to prevent pathogen contamination. The objective of experiment 1 was to determine the impact of 0, 30, 60, or 90 d storage time on fat-soluble vitamin stability when vitamin premix (VP) and vitamin trace mineral premix (VTM) were blended with 1% inclusion of MCFA (1:1:1 blend of C6:C8:C10) or mineral oil (MO) with different environmental conditions. Samples stored at room temperature (RT) (~22 °C) or in an environmentally controlled chamber set at 40 °C and 75% humidity, high-temperature high humidity (HTHH). The sample bags were pulled out at days 0, 30, 60 and 90 for RT condition and HTHH condition. The objective of experiment 2 was to determine the effect of heat pulse treatment and MCFA addition on fat-soluble vitamin stability with two premix types. A sample from each treatment was heated at 60 °C and 20% humidity. For experiment 1, the following effects were significant for vitamin A: premix type × storage condition (P = 0.031) and storage time × storage condition (P = 0.002) interactions; for vitamin D3: main effect of storage condition (P < 0.001) and storage time (P = 0.002); and for vitamin E: storage time × storage condition interaction (P < 0.001). For experiment 2, oil type did not affect the stability of fat-soluble vitamins (P > 0.732) except for vitamin A (P = 0.030). There were no differences for fat-soluble vitamin stability between VP and VTM (P > 0.074) except for vitamin E (P = 0.016). Therefore, the fat-soluble vitamins were stable when mixed with both vitamin and VTM and stored at 22 °C with 28.4% relative humidity (RH). When premixes were stored at 39.5 °C with 78.8%RH, the vitamin A and D3 were stable up to 30 d while the vitamin E was stable up to 60 d. In addition, MCFA did not influence fat-soluble vitamin degradation during storage up to 90 d and in the heat pulse process. The vitamin stability was decreased by 5% to 10% after the premixes was heated at 60 °C for approximately nine and a half hours. If both chemical treatment (MCFA) and heat pulse treatment have similar efficiency at neutralizing or reducing the target pathogen, the process of chemical treatment could become a more practical practice.
