This study aimed to develop a formula and production process for snacks made from germinated brown rice flour and banana flour using the extrusion process. The results indicated that both germinated brown rice flour and banana flour could be effectively used as the main raw materials for snack production via extrusion. The proportion of flour in the formula and production conditions, such as moisture content of the raw materials, barrel temperature, and screw speed, significantly influenced the nutritional value, bioactive compound levels, and antioxidant activity of the final products.
ขนมขบเคี้ยวส่วนใหญ่ทำจากแป้งและไขมัน ทำให้มีแคลอรี่สูง ในขณะที่ปริมาณโปรตีน แร่ธาตุ และสารออกฤทธิ์ทางชีวภาพค่อนข้างต่ำ การบริโภคขนมขบเคี้ยวอย่างต่อเนื่องและมากเกินไปอาจส่งผลกระทบต่อสุขภาพ ดังนั้น การพัฒนาผลิตภัณฑ์ขนมขบเคี้ยวให้มีคุณค่าทางโภชนาการสูงขึ้นจึงเป็นเรื่องสำคัญ โดยสามารถทำได้ผ่านการปรับสูตรส่วนผสมโดยใช้วัตถุดิบที่มีคุณค่าทางโภชนาการสูง และการพัฒนากระบวนการผลิตที่ไม่ต้องทอด เช่น การใช้กระบวนการเอกซ์ทรูชัน การศึกษาในครั้งนี้จึงมุ่งพัฒนาผลิตภัณฑ์ขนมขบเคี้ยวจากแป้งข้าวกล้องงอกและแป้งกล้วยน้ำว้า ซึ่งมีคุณค่าทางโภชนาการและสารออกฤทธิ์ทางชีวภาพโดดเด่น พร้อมทั้งศึกษาสภาวะที่เหมาะสมของกระบวนการเอกซ์ทรูชันเพื่อให้ผลิตภัณฑ์มีคุณภาพและเป็นประโยชน์ต่อสุขภาพ ตรงตามความต้องการของผู้บริโภคในปัจจุบัน

Bio-calcium powders were extracted from Asian sea bass bone by heat-treated alkaline with fat removal and bleaching supplementary method. Cereal bars (CBs) were fortified with produced bio-calcium at 3 levels: (1) increased calcium (IS-Ca; calcium ≥10% Thai RDI), (2) good source of calcium (GS-Ca; calcium ≥15% Thai RDI), and (3) high calcium (H-Ca; calcium ≥30% Thai RDI) which were consistent with the notification of the Ministry of Public Health, Thailand: No. 445; Nutrition claim issued in B.E. 2023. Moisture content, water activity, color, calcium content and FTIR analysis of bio-calcium powders were measured. Dimension, color, water activity, pH and texture of fortified CBs were determined. Produced bio-calcium could be classified as a dried food with light yellow-white color. Calcium contents in bio-calcium powder was 23.4% (w/w). Dimension, weight and color except b* and ΔE* values of fortified CBs were not different (P > 0.05) from those of the control. Fortifying of bio-calcium resulted in harder texture CBs. An increase of fortified bio-calcium amounts decreased carbohydrate and fat but increased of protein, ash and calcium in the fortified CBs. Shelf life of CBs was to be shorten by fortification of bio-calcium powder because of the increment of moisture, water activity and pH. Yield of bio-calcium production was 40.30%. Production cost of bio-calcium was approximately 7,416 Bth/kg while cost of fortified CBs increased almost 2-3 times compared to the control. Calcium contents in IS-Ca (921.12 mg/100g), GS-Ca (1,287.10 mg/100g) and H-Ca (2,639.70 mg/100g) cereal bars could be claimed as increased calcium, good source of calcium and high calcium, respectively. In conclusion, production of cereal bar fortified with Asian sea bass bone bio-calcium powder as a fortified food was possible. However, checking the remained hazardous reagents in bio-calcium powder must be carried out before using in food products and analysis of calcium bioavailability, sensory acceptance and shelf life of the developed products should be determined in further studies.

Climate change and the increasing unpredictability of environmental conditions have aggravated the shortage of animal feed crops during the dry season. This study examines effect of packaging thickness on the quality of corn silage during long-term storage, to maintain its nutritional value during feed shortages. The results show that packaging with thicknesses of 80, 120, 150, and 200 microns effectively maintain good physical quality, including odor, texture, color, and pH levels, during the 0–21day storage period. The silage had a fermented like fruit flavor or vinegar flavor, a silage texture, and well-preserved leaves and stems. Its color remained yellowish-green, with pH values between 3.7 and 4.7. Additionally, lactic acid analysis found that silage in 200-micron-thick packaging for 21 days had the highest lactic acid content (5.64%). However, there were no significant differences in the nutritional value of the silage across different packaging thicknesses
