Research on the optimization of ingredient percentages and baking temperature of Pouteria lucuma formulated cookies was conducted using the response surface method (RSM) for products with the best texture and color. The central composite design (CCD) was applied to examine the effects of ingredient percentages including lucuma flesh (25 – 35%), egg yolk (14 – 18%), baking powder (1,0 – 1,2% based on wheat flour weight), and baking temperature (140 – 160oC) on product quality. The effects of 4 packaging materials namely polyamide (PA), polyethylene (PE), polypropylene (PP), and oriented polyproplene (OPP) on the total microbial count, texture, moisture content, color and sensory of cookies during the storage times of 3, 5 and 7 weeks were analyzed. The results showed that optimized recipe were 27,2 – 29,0% lucuma, 15,3 – 16,7% egg yolk, 1,05 – 1,15% baking powder and baking temperature 148,7 – 150oC which gave the best texture and color of the product. The lucuma added cookies storag in PA, PP, and OPP packaging remained the best quality, while PE showed the lowest products quality in 7 weeks of storage at room temperature.
