1. INCORPORATION OF ESSENTIAL OILS FROM Piper aduncum INTO FILMS MADE FROM ARROWROOT STARCH: EFFECTS ON THEIR PHYSICOCHEMICAL PROPERTIES AND ANTIFUNGAL ACTIVITY
Starch is a promising source of biopolymers and the incorporation of essential oils (EOs) into it can improve some biological properties of films. This study aimed at developing and characterizing barrier, biodegradability and optical properties of biopolymeric films made from arrowroot starch and at incorporating EOs from Piper aduncum leaves and infloresce

2. Tapioca starch films reinforced with microcrystalline cellulose for potential food packaging application
Abstract This work is directed towards developing biodegradable films from biopolymer that is sustainable and environmentally friendly particularly tapioca starch (TPS) films. However, the usage of TPS films for food packaging application has been limited due to the poor mechanical, barrier and thermal properties. Microcrystalline cellulose (MCC) at differen

3. Use of post-harvest films for the maintenance of the visual attributes and ethylene production of ornamental mini-pumpkins
Resumo Nos últimos anos, o mercado consumidor tem mostrado interesse no uso ornamental de alguns frutos que anteriormente eram empregados principalmente para fins alimentares. No entanto, o uso das chamadas ‘mini-abóboras’ para ornamentação pode ser limitado por aspectos ligados à pós-colheita, como despigmentação da casca, perda de massa fresca,

4. Effect of the degree of acetylation, plasticizer concentration and relative humidity on cassava starch films properties
Abstract The objective of this study was to develop films with reduced hygroscopicity and improved mechanical properties from acetylated cassava starch. For that, an acetylation procedure using acetic anhydride as the esterification reagent was performed, resulting in starch acetates with degrees of substitution (DS) of 0.6 (S0.6) and 1.1 (S1.1). Twelve fil

5. Thermomechanical Properties of Corn Starch Based Film Reinforced with Coffee Ground Waste as Renewable Resource
Abstract Starches polymeric films offer several advantages for the replacement of synthetic polymers due to their biodegradability, non-toxicity, availability and low cost. However, the high biodegradation potential can cause fragility, considering some fundamental mechanical properties. Therefore, starch based polymeric films were reinforced incorporating l

7. Edible iron yam and maize starch convenient food flavoring packaging films with lemon essential oil as plasticization
Abstract Lemon essential oil was used as plasticizers to prepare iron yam/maize starch edible films. Changes of physical, microcosmic and antimicrobial properties of films were studied. Results showed that the addition of lemon essential oil led to the decrease of moisture content, transparency, whiteness index, water vapor permeability, solubility and tens

8. Sericin as compatibilizer in starch/ polyester blown films
Abstract This study investigated the effects of low concentrations of sericin (≤ 1.5 wt%) in starch- poly(butylene-adipate-co-terephthalate) (PBAT) films. The films were produced by blown extrusion and mechanical, barrier and structural properties were determined. Films containing 1.0 and 1.5 wt% sericin showed higher tensile strength (6.41 and 6.59 MPa)

9. Starch Films Added of Açaí Pulp ( Euterpe oleracea Martius)
ABSTRACT Edible films are an alternative to synthetic materials used for packaging foods. The aim of this study was to develop and characterize films made from cassava starch, freeze-dried acai and glycerol. The films were characterized for thickness, water vapor permeability, water solubility, anthocyanins, antioxidant capacity and mechanical properties. Th

10. Utilization of Uncaria gambir Roxb filtrate in the formation of bioactive edible films based on corn starch
Abstract The objective of this research was to determine the effect of Uncaria gambir Roxb filtrate addition on functional edible films based on corn starch. This study used a Factorial Randomized Completely Design with two treatments and three replication for each treatment. The first factor was the concentration of Uncaria gambir Roxb filtrate (20%, 30%,

11. Influence of Ionizing Radiation on Biodegradable Foam Trays for Food Packaging Obtained from Irradiated Cassava Starch
ABSTRACT Biodegradable polymers, such as starch, cellulose, and derivatives thereof, are being studied to produce innovative packaging in the most diverse shapes (films, bags, trays, bottles, etc.) to attend this current market trend. The aim of this work was to produce foam trays from cassava starch for food packaging via extrusion followed by thermoforming

12. Materiales eco-compatibles reforzados a base de almidón de mandioca para aplicaciones agronómicas
ABSTRACT Plastic mulch is used in various crops production in order to increase yield, extend growing season, weed control, increase fertilizers efficiency and improve soil conditions. However, since such plastics removal and disposal represent not only an additional cost, but also a source of environmental pollution, interest in starch-based materials as a
