how to target and modify a batch of properties within a typescript class

Issue

How can i simplify all this code. i wish to have one function perform the task below.

should be a simple task i am just fulfilling in more text here as stackoverflow demands more text. Please try to resolve thanks so much! typescript is an awesome language. its a little more different than javascript. when i attempted my own method for trying to resolve the below i got undefined...its hard trying to figure out how to group, target and change the values

class foods {
    private apple: boolean;
    private banana: boolean;
    private guava: boolean;
    private passionfruit: boolean;
    private melon: boolean;
    private oranges: boolean;
    private porkchop: boolean;
    private steak: boolean;
    private chicken: boolean;

    toggleApple() {
        this.apple = true;
        this.banana = false;
        this.guava = false;
        this.passionfruit = false;
        this.melon = false;
        this.oranges = false;
    }

    toogleBanana() {
        this.apple = false;
        this.banana = true;
        this.guava = false;
        this.passionfruit = false;
        this.melon = false;
        this.oranges = false;
    }

    toggleGuava() {
        this.apple = false;
        this.banana = false;
        this.guava = true;
        this.passionfruit = false;
        this.melon = false;
        this.oranges = false;
    }

    togglePassionFruit() {
        this.apple = false;
        this.banana = false;
        this.guava = false;
        this.passionfruit = true;
        this.melon = false;
        this.oranges = false;
    }

    toggleMelon() {
        this.apple = false;
        this.banana = false;
        this.guava = false;
        this.passionfruit = false;
        this.melon = true;
        this.oranges = false;
    }

    toggleOranges() {
        this.apple = false;
        this.banana = false;
        this.guava = false;
        this.passionfruit = false;
        this.melon = false;
        this.oranges = true;
    }

}

Solution

You can allocate everything into a single function. I'm sure there would be much more creative solutions, though this solution would at least put all the logic into a single toggle function.

apple: boolean;
banana: boolean;
guava: boolean;
passionfruit: boolean;
melon: boolean;
oranges: boolean;
porkchop: boolean;
steak: boolean;
chicken: boolean;

constructor(
) {
    this.apple = false;
    this.banana = false;
    this.guava = false;
    this.passionfruit = false;
    this.melon = false;
    this.oranges = false;
}

toggleFruit(fruitName: string) {
    (fruitName === 'apple' ? this.apple = true : this.apple = false);
    (fruitName === 'banana' ? this.banana = true : this.banana = false);
    (fruitName === 'guava' ? this.guava = true : this.guava = false);
    (fruitName === 'passionfruit' ? this.passionfruit = true : this.passionfruit = false);
    (fruitName === 'melon' ? this.melon = true : this.melon = false);
    (fruitName === 'oranges' ? this.oranges = true : this.oranges = false);
}
