Across the UK, the Trussell Trust charity provided food parcels to 126,697 people in 2011-12, more than double the number from the previous year, with almost 46,000 children fed by the trust last year. It estimates that by 2016, 500,000 people a year will receive a food parcel.
CAS chief executive Margaret Lynch said: "The report reveals a Dickensian situation facing many of Scotland's low paid workers and people who rely on welfare benefits. The national minimum wage has failed to keep pace with the massive increase in food prices over the last five years, leaving many low income families facing food insecurity.
"The fact that 50% of those getting food parcels are working is shocking. The fact that the remaining 50% who rely on food parcels do so because their benefit payments are delayed or because of changes to their benefits entitlement is both avoidable and disgraceful."
A UK Government spokeswoman said: "We're committed to supporting people on low incomes, which is why we have increased the personal allowance to take more than two million people out of tax and given a triple lock for rises in the basic state pension.
"The benefits system provides a safety net to cover costs such as food and housing and these benefits increase every year in line with inflation. We also provide emergency financial support through crisis loans if people find themselves in trouble."
