The mango (Mangifera indica Linn.) is one of the most important tropical fruits in Thailand.Approximately 60% are processed for edible mango products. During processing ofthe mango, by products such as peel and kernel are generated. As seed kernel is notcurrently utilized for any commercial purposes, it is discarded as waste. The aim ofthis survey study was to examine the behavior of Thai food manufacturers regarding mangoseed (MS) waste management for feasibility of MS utilization. Questionnaires were usedwith 103 randomly selected factories. Detailed investigations on the general informationand management of mango waste in the experimental factories revealed that 42.1%of mango processing factories in Thailand are small and medium enterprises whichhave 51-100 employees. The most common varieties of mango used in the industry areKaew and Choke Anan varieties, which accounted for 29.5% and 27.9%, respectively.The mean rate of MS waste generation was 1,063 kgs. per week. About 73.7% of themango waste generated (measured by weight) is well managed to separate the wasteby variety. About 47.4% of manufacturers proposed that the cost of mangoseed kernel (MSK) waste separated according to variety was 100-500 baht per ton.Based on this investigation, mango seed may be a cost-effective and high volumesource to utilize as a raw material.
