The growing interest in conserving the environment is motivating the development of biodegradable packaging for food from agro-industrial waste. Corn crops and Mexican pinion generate considerable amounts of lignocellulose waste that can be used as feedstock to make paper packaging. The objective of this work was to elaborate and characterize a paper packaging from cellulose of fibrous residues of Mexican pinion (CCJ) and corn stem/leaves (CTM), and to determine its functionality in prolonging the useful life of serrano peppers stored at room temperature. Paper was made from different concentrations (100-0 to 80-20%) of CTM and CCJ by alkaline method with NaOH. Paper formulation P5 was selected corresponding to a relation 95-5% of CTM-CCJ respectively with the purpose to use it to preserve quality in Serrano pepper (grammage 97.0 g/m2, hardness 3112 MPa, thickness 0.25 mm). The use of P5 as packaging for Serrano pepper favors the values of firmness, moisture, color and vitamin C with respect to the control pepper during the days of storage at room temperature. The properties of texture and color are extremely important in the qualitative quality of Serrano pepper, since being a variety of fresh consumption, are criteria for consumption or acquisition of this product.

Keywords : paper packaging; corn; mexican pinion; serrano pepper; postharvest storage.
