dynamic id for li tag

问题

How can I create a dynamic id of li tag using the foodInfo which is set to c:set?

<c:forEach var="food" varStatus="i" items="${selectedIngredientsList}">
        <c:set var="foodInfo" value="${food.foodItemId}~${food.foodCategoryId}~${food.foodName}~${food.foodPortionName}"/>    
        <ul>
            <li id="??"><c:out value="${food.foodName}"/>
            </li>
        </ul> 
</c:forEach>
