Nuts are a great source of nutrients, including vitamin E, magnesium and phosphorus. They’re also loaded with antioxidants. Some of these nutrients are sensitive to heat and might be lost during the roasting process. For example, some types of antioxidants are degraded during roasting. Antioxidants are important for your health because they help protect your cells against damage from free radicals. Nevertheless, increased temperature and roasting time have been shown to decrease antioxidant activity, but only up to a certain point. In one study, the levels of antioxidants in various nuts decreased constantly from the start of roasting at 302°F (150°C) until 30 minutes later. Interestingly, the antioxidant activity increased after 60 minutes.
This is because compounds that have antioxidant activity are formed in a chemical reaction when nuts are roasted. Furthermore, not all antioxidants are damaged by roasting. One study reported that the amounts of the antioxidants lutein and zeaxanthin in pistachios and hazelnuts were not affected by roasting. Öz Star Machinery Company.

Studies also indicate that vitamin E, thiamine and carotenoids are lost
during roasting. However, the extent of the loss really depends on the nut type and roasting temperature. In
fact, one study showed that roasting almonds
and walnuts caused a greater
vitamin loss than roasting hazelnuts, while almost no vitamin loss occurred
during the pistachio roasting process. The extent to which vitamin loss
occurred increased in line with increased roasting temperatures. Öz Star Nuts roasting machines provide the best quality
