Simply iterate on the object and check for the emptiness of the value

e.g: on nodejs console: 

> const st = {
...     Flouer:'12',
...     Milk:'3',
...     Oil:'11',
...     Salt:'',
...     Eggs:'',
...     Tomatos:'',
...     Meat:''
...   }
undefined
> st
{ Flouer: '12',
  Milk: '3',
  Oil: '11',
  Salt: '',
  Eggs: '',
  Tomatos: '',
  Meat: '' }

>for (var po in st) { if (Object.keys(a1[po]).length > 0 )  { console.log("value of the key " + po + " value is " + a1[po]) } }

Outputs:

value of the key Flouer value is 12
value of the key Milk value is 3
value of the key Oil value is 11
