The use of freeze drying process to prolong the shelf life of food products is considered mainstream in food industries due to its capability to retain the nutritional value. Citric acid and osmotic solution were used as a pre-treatment in this study to produce high-quality dried products. Four treatment groups were observed, including untreated (control), 1% citric acid (CA), 1% CA with 20% sugar solution (CAOD 20%), and 1% CA with 60% sugar solution (CAOD 60%). Physical properties such as moisture content; pH; total soluble solid; colour value; and bioactive compounds, such as vitamin C, total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activities were evaluated in freeze-dried pineapples. The result showed that CAOD 60% demonstrated a positive effect, with the least moisture content and the lowest value of colour changes (ΔE) at 5.69 ± 0.04% and 33.76 ± 2.17, respectively, as compared with that of other samples. In terms of phytochemical, the control and CA groups recorded higher retention of vitamin C, TPC, and TFC compared with other osmotic dehydration samples; however, there was no significant effect (p<0.05) on TPC and TFC. Interestingly, CAOD 60% possessed strong antioxidant activity, with the lowest IC50 value of 85.85 ± 5.93. From these findings, it was found that CAOD 60% resulted in positive effect on both the physical qualities and preservation of antioxidant activity, making it a recommended condition for pre-treatment in fruit preservation, which is essential in ensuring both the food security aspect and maintenance of its nutritional value.

Mango (Mangifera indica) and pineapple (Ananas Comosus) are tropical fruits that contain many nutrients, one of which is antioxidants and polyphenols. Lots of studies have shown that fermented fruit is higher in antioxidants and health benefits. Antioxidants have been reported to be an alternative to enhance body immunity and possibly become an Anti -SARS-CoV-2. One of the antioxidants that are easily found in vitamin C. This study is to process the fermented mango and pineapple fruits into cookies and to test the antioxidant content (especially Vitamin C) in vitro. There were three variations of the formulation, mango: pineapple: CO2 free water. Sample 1 (1: 0.5: 0.5), sample 2 (2: 1: 1) and sample 3 (3: 2: 2). Then, all product samples were inoculated with Lactobacillus paracasei 5% b/v for 14 days under anaerobic conditions to get simpler mangoes and pineapple food fibre. The fermented products were made into flour with a freeze dryer. Sample variation is done to determine the average significance of the antioxidant content in it. The next step was Vitamin C analysis from 3 samples of cookies sample using Titration Iodometric Method, to determine the amount of Vitamin C (mg/100 g) and also the antioxidant activity with 2,2-diphenyl-1-picrylhydrazyl (DPPH). The amount of vitamin C obtained in Sample 1 was 100.20 mg/100 g respectively with antioxidant activity is 35.33%. Sample 2 was 95.75 mg/100 g respectively with antioxidant activity is 30.60%. Sample 3 was 107.90 mg/100 g respectively with antioxidant activity is 44.70%. The formulation with the highest amount of cookies sample containing vitamin C is S3. There was a significant difference (P<0.05) that determined vitamin C levels between sample formulations. The mean ash content of the three samples was 2.02±0.04% and water content were 1.60± 0.15%. The average vitamin C levels in the three sample cookies were 101.28±6.14 mg/100 g. Sample 3 indicated the best antioxidant activity towards 2,2-diphenyl-1- picrylhydrazyl (DPPH) in the amount of 44.70%. Therefore, fermented mango and pineapple have a great potential to be developed into healthy snack cookies. The vitamin C and antioxidants content in cookies from the fermentation of mango and pineapple may be a great substitute for snacks since antioxidants has the ability to improve immunity and anti-inflammatory response. These cookies are also good prebiotics for the gut microbiome which plays a good role in the immune system.
