摘要
Seed sprouts are susceptible to microbial contamination; therefore, use of an effective sanitization treatment on these products is of great importance. This study investigated the effects of ultrasonication, heating and chemical washing on sanitization of nine crop seeds and the microbial safety of sprouts produced from decontaminated seeds. Most of the sanitization treatments improved seed germination (except dry heating), reduced microbial loads on produced sprouts, and increased sprouts yield. However, only ultrasonication treatment reduced both the total aerobic counts and total coliforms counts to < 3 log (10) CFU g(-1) level on produced alfalfa, mung bean pea and radish sprouts. The sprouts produced from ultrasonication-treated alfalfa, mung bean, pea and radish seeds also outyielded their respective non-treated sprouts by 88, 25, 73 and 56%. Therefore, ultrasonication can be used as a seed sanitization treatment for producing alfalfa, mung bean, pea and radish sprouts.
