Not quite. It can do:

"foods" : [ "Salad", "Fish", "Shellfish", "Vegetarian" ]

Jolt is about transforming the JSON structure of your data, not "transforming" / running arbitrary logic on the content of your data.
As such, it can put your data into a JSON Array, but it can't run a String concatenation on it.

I created a unit test (for Chainr) with this transform. You can see the spec to generate the "foods" array here :

{
    "input": {
        "food_pairing": [
            {
                "food_id": "7",
                "food_name": "Salad"
            },
            {
                "food_id": "12",
                "food_name": "Fish"
            },
            {
                "food_id": "13",
                "food_name": "Shellfish"
            },
            {
                "food_id": "19",
                "food_name": "Vegetarian"
            }
        ]
    },

    "spec": [
        {
            "operation" : "shift",
            "spec" : {
                "food_pairing": {
                    "*": {
                         // put the Json value found at input key "food_name",  
                         // under the output key "foods" where the JSON value at "foods" is an array
                        "food_name": "foods[]"  
                    }
                }
            }
        }
    ],

    "expected": {
        "foods" : [ "Salad", "Fish", "Shellfish", "Vegetarian" ]
    }
}

I hope that helps.
