                                defaultValue={"Select"}
                                onChange={(e) => { this.setState({ food: e }) }}
                            >

                                <Option value="fried Rice">fried Rice</Option>
                                <Option value="Vegetable Soup">Vegetable Soup</Option>
                                <Option value="Pizza">Pizza</Option>
                                <Option value="crab">crab</Option>
                                <Option value="burger">burger</Option>
                            </Select>
                            )}

                        </Form.Item>

 public function saveFoods(Request $request){
        try {
          $jsonData = json_decode($request->getContent());
          $saveDetails = new Foodmodel();
          $saveDetails->food = $jsonData->food;
          $saveDetails->save();
        } catch (Exception $e) {
            ErrorHandler::logError($e, 'Error');
            return $this->jsonResponse('error', $e->getMessage());

        }
    }

Answer

If you’re simply trying to save the food list as a comma separated string:

 $saveDetails->food = implode(',', $jsonData->food);

Or better yet, add the food attribute to your models $casts property to automatically handle the conversion between an array and string.

See the docs here for casting details.
