This research was aimed to study postharvest senescence of fresh Bambusa sp. shoot. The harvested bamboo shoots were packed in linear low-density polyethylene (LLDPE, 0.07 mm thick) bag and stored in 2 conditions: ambient (29±3°C) and refrigerated temperatures (5±3°C). The physical and chemical properties during the 7 days storage were investigated for postharvest quality management. The storage of the bamboo shoots at ambient greatly affected the physical and chemical properties (weight loss, discoloration, reducing sugar content and total acidity content) compared to the refrigerated storage. Under the ambient storage, critical weight loss of shoots (approximately 5) was recorded at day 4 storage along with the darkening of the basal section. Moreover, the reducing sugar rapidly decreased to 50% of the initial at day 2 storage. Sensory evaluation was conducted, and consumers were able to accept bamboo shoots stored at ambient up to one day of storage. On the other hand, bamboo shoots stored in refrigerated up to 7 days were acceptable. This is due to the quick change of color and odor of the bamboo shoots which can be the quality indicators of the harvested shoots.
This study is aimed to develop the manufacturing process of the jelly mushroom drink using primary good manufacturing practice (GMP) for community enterprise, Phitsanulok, Thailand. The evaluation of the existing production process highlighted that the process had risks of cross-contamination, including from the plant layout, which still lacking in food safety management systems. Therefore, the improvement of process manufacturing and layout planning could be divided into three steps: (1) process analysis, (2) line production development, and (3) design plant layout to prevent and reduce crosscontamination causes. The cross-contamination incidence was reduced upon the improvement of the plant layout and processing as observed from the results of the amount of total plate count were reduced from 1.9 × 10 7 to <1 CFU/mL, where yeast and mold and 29 to 8.3 CFU/mL respectively. Meanwhile, the counts for Salmonella spp. and Staphylococcus aureus were below the detection level, whereas Clostridium perfringens, Bacillus cereus, and Listeria monocytogenes were not detected in all samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
