Lemony Poppy Seed Loaf

I found this recipe in a magazine a long time ago..it has a very lemony flavor and I love that! I'm sure this loaf would freeze well but I can't say that for sure as mine never made it till there.

1 3/4 cups flour
1 tsp baking soda
1/2 tsp baking powder
2 tbsp poppy seeds
2 tbsp grated lemon zest
2/3 cup sugar
1/3 cup oil
1/3 cup applesauce
3/4 cup sour cream
1/4 cup lemon juice (approx 2 lemons)
3 egg whites

Glaze..1/2 cup icing(powdered) sugar and 1 tbsp lemon juice

Beat egg whites till soft peaks form and set aside.
In large bowl mix flour, poppy seeds,lemon zest, baking powder and baking soda.
In medium size bowl combine sugar, oil and applesauce. Whisk in lemon juice.
Stir this mixture into the flour mixture alternately with the sour cream.
Fold in beaten egg whites.
Pour into a greased 9x5" loaf pan and bake at 350 for 45 to 50 min or until toothpick inserted comes out clean.
Cool in pan for 10 min before removing to rack. Mix the glaze and pour over loaf. Cool, slice and serve!
