The profits of melon seeds roasting will be affected by factors such as region, brand, sales platform, etc. For example, if the calculation is 10 yuan per kilogram of fried melon seeds, excluding the cost of 7 yuan (calculated based on 70% of the raw material cost), The profit per kilogram of melon seeds is 3 yuan, and the profit rate is 30%. In addition, if the sales volume of the roasted seeds and nuts store is relatively large, the price of melon seeds purchased wholesale will be lower, so the profit will be higher.
