A = im2double(imread('fruit.png'));
B = 1-((1-A).*(1-permute([1 0 0],[1 3 2])));
figure;
imshow(B)

I don't know if this is what you have in mind, but maybe something like this:
whiteness = 0.5;
A = im2double(imread('fruit.png'));
B = mean(A,3).*ones(1,1,3)*(1-whiteness)+whiteness;
figure;
imshow(B)
Here, whiteness is a parameter for you to tune (between 0 and 1, inclusive) in order to achieve the desired "whiteish"-ness.
whiteness = 0; will give you the grey-scale version of the original image where each RBG channel is the average of all three RGB channels in the original image. whiteness = 1; will give you an image of all white.

You can make an image "whiter" by decreasing the saturation and increasing the value.
hsvImage = rgb2hsv(rgbImage);
[hImage, sImage, vImage] = imsplit(hsvImage);
sImage = someFactor1 * sImage; % someFactor1 < 1 to reduce vividness of color
vImage = someFactor2 * vImage; % someFactor2 > 1 to brighten the image
hsvImage = cat(3, himage, sImage, vImage);
rgbImage = hsv2rgb(hsvImage);
