Can lemon after keeping outside for 48 min used in paryushan

The context from the Jain literature database discusses fasting practices during Paryushan, including rules about food and drink consumption, such as drinking boiled and cooled water during the day and the importance of uncontaminated food and water for monks breaking fast. However, there is no explicit mention or guideline regarding the use of lemon or any specific food item kept outside for a certain duration during Paryushan. Jain fasting and dietary rules emphasize purity and uncontaminated food, but without direct reference to lemon or timing, no definitive answer can be provided from the given sources.
