The use of borax solution as a preservative in wood and bamboo materials is well known in the community. A borax solution is an environmentally friendly liquid that can dissolve in water, so it is suitable to be used as a preservative within cold or hot soaking techniques. The ability of borax to resist insects and fungus attacks on bamboo has been proven, but the effect of the solution on the strength of bamboo must also be investigated. This study conducts to investigate the effects of borax and its additives as preservative solutions to the mechanical properties of bamboos. The bamboos preservations were conducted by cold conditions of immersion, while the mechanical properties were performed to understand the effects of preservatives. The result of this study indicated that 30% to 50% borax in the preservative solution is sufficient to provide significant increase in strength for compressive strength, tensile strength, and bending strength of bamboo specimen. From this study, the use of borax solution in preserving the bamboos materials improved the quality of bamboos based on its mechanical properties.

Introduction: The procedure to synthesize silver nanoparticles (SNPs) from Prunus cerasoides leaf extract and their effect on vase life and flower quality of cut carnation were investigated. Methods: SNPs were bio-synthesized from Prunus cerasoides leaf extract and characterized by using UV-Vis technique, TEM, and SEM images. The postharvest responses of carnation cut flowers to the biosynthesis SNPs were evaluated through vase life, relative fresh weight, vase solution uptake, flower diameter of cut carnation. Results: SNPs were synthesized under optimum conditions, including using the extract of leaf heating at 60 oC in 30 min, 4 mM of silver nitrate, pH of 11, and 180 min of reaction time. SNPs exhibited antimicrobial activity and then alleviated the bacterial development in the preservative solution. All treatments with SNPs had improved the vase life and quality of cut carnation compared to the control. A vase solution containing 2% sucrose enhanced the carnation cut flowers. Conclusions: The preservative solution containing 25 ppm SNPs and 2% sucrose showed the best effect. SNPs could be used as a promising antibacterial agent applied in the preservative solution for cut carnation flowers.

Cut snapdragons (Antirrhinum majus L. cvs. Fujinoyuki, Oakland, and Bismarck) were harvested at three different stages and pulsed with silver thiosulfate (STS). Then, the flowers were treated with several preservative solutions to test the effects on vase life and flower quality. Proper storage methods were also investigated. The best harvesting time of snapdragon was when seven to nine florets were opened in a spike. The flowers harvested at this stage had more fresh weight, increased number of opened flowers per spike, and longer vase life than those harvested at earlier stages. Pulsing with 0.2 mM STS for 16 h improved flower quality and prolonged vase life. The preservative solution containing 2% sucrose + 150 ppm 8-hydroxyquinone citrate (HQC) + 25 ppm AgNO3 prolonged vase life. However, this solution caused longer internode between florets and excessive elongation of spike. The preservative solution containing 2% sucrose + 150 ppm HQC + 25 ppm AgNO3 + 50 ppm daminozide improved flower quality by prolonging vase life, reducing the length of internode between florets, and preventing excessive elongation of spike. The flowers held in 50% 7-Up had 2 times prolonged vase life compared to water control. The flowers held in 4% ethyl alcohol also had prolonged vase life and increased fresh weight. Ethylene caused floret abscission and STS pretreatment prevented this floret abscission. Ethylene production in cut snapdragons maintained 2 to 6 nl/g fresh weight per h during vase life. The prolonging storage at low temperature (1C) shortened vase life. The flowers pretreated with STS, and then held in preservative solution during cold storage, had better flower quality and longer vase life than those in plain water.

Abstract Fish meat is more nutritious source of protein and relatively safe for human consumption. Fish meat more easily damaged than red meat product quality, so it is necessary that the process of pickling fish maintained in fresh condition and suitable for consumption. The ethanol extract of red algae Kappaphycus alvarezii been known have antioxidant and antimicrobial effects, so need some research on the use of red algae extract as a preservative. Red algae extract with a concentration of 400 ppm, 500 ppm, 600 ppm and 1 % formalin, each sample is used as a meat preservative for tilapia fillets as 40 grams. Samples of tilapia meat is soaked in an preservative solution as long as 60 minutes. During immersion, the samples of tilapia meat stored at room temperature. Observation of tilapia meat quality is done about six hours after meat removed from the preservative solution. Fish meat quality were analyzed to describe the organoleptic quality, methods of the TPC, and proximate analysis. The results showed that the ethanol extract of red algae Kappaphycus alvarezii 600 ppm has potential as a natural preservative based on test results of TPC, proximate and organoleptic test.
