Abstract:The aim of this study was to carry out an investigation on antioxidant activity and phenolic compounds of the mango seed kernel (MSK) waste and to examine the behavior of Thai food manufacturers about mango seed (MS) waste management for feasibility of MS utilization. Eleven different cultivars of MSK wastes donated from manufacturers in Thailand were collected. The antioxidant activities using the stable radicals 1-diphenyl-2-picrylhydrazyl (DPPH•) and the phenolic compounds of MSK in form of free phenolic acid, esterified phenolic acid, insoluble bound phenolic acid and total flavonoid content were evaluated. Detailed investigations of 103 randomly selected factories gave general information about the management of mango wastes in the factories. The results showed that all MSK exhibited antioxidant activities comparable to a-tocopherol. Cultivar KW and CA extracts showed the highest antioxidant efficiency. The phenolic acid of KW had the highest value of 74.99 + 0.65 milligrams of gallic acid equivalents per 100 grams of fresh weight (mg of GAE/100 g fresh), whereas CA gave the highest flavonoid content (30.16 + 0.21 milligrams of rutin equivalents per 100 grams of fresh weight (mg of RUE/ 100 g fresh)). The most common varieties of mango used in industrial processes are Kaew and Choke Anan varieties which accounted for 29.5% and 27.9%, respectively. The mean generation rate of MS waste was 1,063 kg per week. About 73.7% of the mango waste generated (measured by weight) is well managed and separated by variety. About 47.4% of manufacturers proposed that the cost of mango seed kernel (MSK) waste separation by variety was 100-500 baths per ton.
