| Abstract | This research aims to develop a prototype ethanol vapor-release control package for use to delay the deterioration of fresh-cut strawberry CV. Praratchatan 80. The control sachet contained silica gel saturated with liquid ethanol. The front of the control sachet was made of low-density polyethylene (LDPE) film and the back was made from AL/PE size 3 x 3 cm and 6 x 6 cm. The sachet contains ethanol-saturated silica gel at 1 and 2 g, respectively. Then, the ethanol vapor release sachet is packaged into a package of fresh-cut strawberries. Research findings on the relationship between ethanol vapor release and level of ethanol vapor concentration in the packaging atmosphere at 5 °C. Ethanol vapor release was found to continuously increase concentration and then reach a steady state in 48 h and reach a maximum value in 72 h. The sachet sizes 3x3 and 6x6 cm had the highest ethanol vapor concentration values of 107.95 ± 9.38 and 182.50 ± 21.10 ppm, respectively. The study found that using an ethanol vapor control sachet together with fresh-cut strawberries (200 grams) in a packaging box stored at 5 °C for 7 days resulted in ethanol vapor helping to slow down weight loss. The effects of ethanol vapor on anthocyanin content and vitamin C showed no significant difference after one day of storage. Total phenolic content (TPC) and antioxidant activity (DPPH) increased during 1-3 days of storage and then continuously decreased throughout the shelf life. However, the microorganisms grew at a slower rate compared to the control sample. The 1gS3 control sachet has a suitable production cost for packaging fresh-cut strawberries. The control sachet importantly suggests that the ethanol vapor released has slowed down the deterioration and growth of microorganisms in fresh-cut strawberries cv. Praratchatan 80. |
