How to split the object in Jquery?

I have an object .I want to append it to the Select tag using Jquery.I can able to add the first column of an object into Sucessfully.But I can't able to catch the second column

var obj=[{Series1,10},
{Series2,20},
{Series3,30},
{Series4,40},
{Series5,50},
{Series6,60},
{Series7,70}]

I want to split into separate variables.

function Load() {
var cuisines =obj;
var set = document.getElementById('ddllicence');
for (var i = 0; i < cuisines.length; i++) {
var opt = document.createElement('option');
//Append the first row into the name
opt.innerHTML = cuisines[i]; (Series1)
//Append the Second row into the Value
opt.value = cuisines[i]; (10)
set.appendChild(opt);
}

Please help me to solve my issue.
