Recently, the indicator of food security in Indonesia has improved not only seen by food availability but also food utilization. The household consumption pattern has shifted from carbohydrates to another nutrient included protein, even though the change is relatively small. One of the ways to the household to meet their needs for protein source food is from own-produced food. Households which have own-produced food will allocate their food crops especially when the price increased. This study aims to analyze the consumption pattern of high protein source food either from plants or animal source. It applies the Quadratic Almost Ideal Demand System (QUAIDS) to estimate households responsivity towards price and expenditure changes, especially for own-produced food commodities. The results reveal that when the price of animal protein increase, a household will shift to consume cheaper source from plant protein. The value of own-price elasticity was more inelastic in rural and poor households. This indicates that when there is a price increase, those households tend to consume from own-production food. It is also suggested that there is a role from the small-farming scale as a household strategy to improve their food security.
