การพัฒนาแผ่นฟิล์มบริโภคได้ไลโคปีนสูงจากเยื่อหุ้มเมล็ดฟักข้าว

Abstract

This research aimed to study the concept development for eye health supplements; the optimal formula of high lycopene edible film products made from gac aril; the physical, chemical, and mechanical properties as well as the consumer acceptance of high lycopene edible film products made from gac aril. Regarding the concept development for eye health supplements, a sample group of 150 consumers was surveyed through questionnaires. In addition, the optimal formula of high lycopene edible film products made from gac aril was investigated. The factors included 5%, 10% and 15% of cassava starch content and 10%, 20% and 30% of sorbitol were studied in factorial CRD experiments. Next, the optimal formula was selected based on the physical properties (film solubility), the mechanical properties (the tensile strength and the elongation at break) together with the consumer acceptance. The 9- point hedonic scale was used to measure 100 consumers’ preference. After that, the optimal formula of high lycopene edible film products was developed. Then, the nutritional, physical, and microbiological properties of the products were examined. Later, the consumer acceptance of high lycopene edible film products made from gac aril was studied. According to the concept development for eye health supplements, 31.40% of the consumers wanted instantly melting in the mouth films. 41.70% of the consumers believed that the compound helping maintain eye health was Beta-Carotene. Moreover, if the instantly melting in the mouth that could help maintain eye health were developed, 76.00% of the consumers would be interested. Furthermore, it was found that the optimal formula of high lycopene edible film products was the 8th formula. It included wheat flour (10%), cassava starch content (10%), and sorbitol (30%) of gac aril. The study of the product nutritional properties pointed out that the products contained 15,906.77 μg of Beta-Carotene and 17,017.69 μg of lycopene. The product physical property indicated the water activity of 0.54. The microbiological property of the product passed the requirement of the Notification of the Ministry of Public Health No.420 B.E. 2563 (2020) entitled “Food in a Hermetically Sealed Container”. The average consumer acceptance of high lycopene edible film products made from gac aril was at 7.61 ± 0.08. Finally, when the consumers learned benefits and nutritional information of the product, 90% of them decided to buy the product.
