“…Pineapple stem waste, a byproduct of a proprietary bromelain extraction process, was obtained from Hong Mao Biochemicals Co., Ltd., (Rayong, Thailand). In general, the process involves crushing peeled pineapple stems to disrupt the cell structure and extract liquid by centrifugation [ 28 ]. The remaining solid material was dried under the sun for a few days and further ground into a powder using a grinder.…”

“…Recently, our group started investigating pineapple stem starch (PSS) as a promising material for a variety of applications. This is because the PSS has a relatively high amylose content and can be obtained from pineapple field waste, which is abundantly available in Thailand [ 26 , 27 , 28 ]. We reported that the PSS film exhibits good properties, such as high water resistance, low water absorption, and good mechanical strength, while still being readily biodegradable [ 29 ].…”

Plastic waste poses a significant challenge for the environment, particularly smaller plastic products that are often difficult to recycle or collect. In this study, we developed a fully biodegradable composite material from pineapple field waste that is suitable for small-sized plastic products that are difficult to recycle, such as bread clips. We utilized starch from waste pineapple stems, which is high in amylose content, as the matrix, and added glycerol and calcium carbonate as the plasticizer and filler, respectively, to improve the material’s moldability and hardness. We varied the amounts of glycerol (20–50% by weight) and calcium carbonate (0–30 wt.%) to produce composite samples with a wide range of mechanical properties. The tensile moduli were in the range of 45–1100 MPa, with tensile strengths of 2–17 MPa and an elongation at break of 10–50%. The resulting materials exhibited good water resistance and had lower water absorption (~30–60%) than other types of starch-based materials. Soil burial tests showed that the material completely disintegrated into particles smaller than 1 mm within 14 days. We also created a bread clip prototype to test the material’s ability to hold a filled bag tightly. The obtained results demonstrate the potential of using pineapple stem starch as a sustainable alternative to petroleum-based and biobased synthetic materials in small-sized plastic products while promoting a circular bioeconomy.

This study aimed to evaluate physicochemical and sensory characteristics of corn grits and pineapple stem starch-based extruded snacks enriched with oyster mushroom powder (OMP). Base materials (corn grits and pineapple stem starch at a ratio of 1:1) were mixed with OMP at levels of 5, 10 and 15% (w/w, total dry ingredients basis). The mixtures of dry ingredients were adjusted to 15% moisture content, followed by adding 4% palm oil. The mixtures were kept at room temperature overnight before being extruded using a twin-screw extruder with barrel temperatures of 80-140 °C and screw speed of 450 rpm. Increasing levels of OMP resulted in increased bulk density, hardness, redness, cell wall thickness, total phenolic content and antioxidant activity of extruded snacks but decreased expansion ratio, lightness and yellowness values. X-ray diffraction showed that extruded snacks with increasing levels of OMP resulted in higher amounts of V-type crystals, indicating to the greater formation of amylose-lipid complex. Sensory evaluation showed that extruded snacks with 5% OMP had the highest preference levels for all sensorial attributes. This study demonstrates that pineapple stem starch and OMP can be used to produce nutritionally enriched and acceptable extruded snacks.

“…Hereafter, the starch is denoted as PSS. Only recently has more attention been paid to exploring different ways to utilize this PSS [ 31 , 32 , 33 , 34 , 35 , 36 ]. To the best of our knowledge, there is very limited work on the use of PSS as packaging material.…”

Toward a Circular Bioeconomy: Exploring Pineapple Stem Starch Film as a Plastic Substitute in Single Use Applications

In this study, biodegradable starch film was developed from pineapple stem waste as a substitute for non-biodegradable petroleum-based films for single-use applications where strength is not too demanding. High amylose starch from a pineapple stem was used as the matrix. Glycerol and citric acid were used as additives to adjust the ductility of the material. Glycerol content was fixed at 25% while that of citric acid varied from 0 to 15% by weight of starch. Films with a wide range of mechanical properties can be prepared. As more citric acid is added, the film becomes softer and weaker, and has greater elongation at the break. Properties range from a strength of about 21.5 MPa and 2.9% elongation to a strength of about 6.8 MPa and 35.7% elongation. An X-ray diffraction study showed that the films were semi-crystalline. The films were also found to be water-resistant and can be heat-sealed. An example of a single-use package was demonstrated. A soil burial test confirmed that the material was biodegradable and completely disintegrated into sizes smaller than 1 mm within one month.
