Although low dose (1 kGy) reduced the APC (6.15-2.

Effect of Rice Processing towards Lower Rapidly Available Glucose (RAG) Favors , a South Indian Fermented Food Suitable for Diabetic Patients.

The Asian food pattern primarily embraces rice and rice-based products, which mainly comprise 90% starch. Among these various food products, is mostly prepared through fermentation. It has high palatability, and the rapid and highly digestible nature of the food product results in a higher post-glucose level in diabetic patients.

Effects of electron-beam irradiation on the quality characteristics of mandarin oranges (Citrus unshiu (Swingle) Marcov) during storage.

Consumption and global utilization of mandarins is on the rise due to its easy-to-peel attribute compared to other citrus fruits. Mandarins are irradiated as an effective phyto-sanitary treatment for trade requirements. In this study, mandarins were irradiated with 0.

Storage stability of soluble pigments, chlorophylls, and carotenoids in electron-beam-irradiated edible lavers (Porphyra umbilicalis) with impact on microbial safety and sensory characteristics.

Background: In this study, we investigated whether electron beam (e-beam) irradiation can inactivate microbial populations, including aerobic bacteria plate count, fungi, and coliforms, in two types of lavers (dried and roasted). The impact of e-beam doses of 4 and 7 kGy on microbial populations, color values, total soluble pigments, chlorophylls, and carotenoid content immediately and after storage at 4, 15, 25, and 35 °C for 4, 8, and 12 weeks was also evaluated.

Results: The initial microbial load of approximately 10 and 10  CFU g in both dried and roasted lavers was reduced to 10 and 10  CFU g , respectively, after irradiation at 7 kGy.
