Spent coffee grounds (SCGs) are waste from coffee drink process, which are rich of a varieties of nutrients. This research applied SCGs as ingredient in cracker. The optimized formula and process are studied as well as addition of different levels of SCGs were studied. It was found that addition of SCGs in cracker had hedonic score in high level from panels, especially panels who drink coffee. Moreover, it was observed that SCGs could increase nutrients especially carbohydrate and fiber to the product.
ผลิตภัณฑ์เบเกอรี เป็นผลิตภัณฑ์ที่ผู้บริโภคนิยมชื่นชอบ และสะดวกต่อการบริโภคทั้งในเวลาเร่งด่วนและเวลาว่าง โดยเฉพาะแครกเกอร์ซึ่งเป็นหนึ่งในผลิตภัณฑ์ที่สะดวกพกพา และสามารถนำมาบริโภคได้ในทุกช่วงเวลา การเสริมคุณค่าทางโภชนาการในแครกเกอร์ จึงมีส่วนช่วยให้ผู้บริิโภคได้รับประโยชน์มากขึ้น นอกจากนี้ แครกเกอร์มีองค์ประกอบของส่วนผสมที่อาจส่งผลต่อคุณภาพ โดยเฉพาะไขมัน แนวมลทางการใช้ประโยชน์จากวัตถุดิบที่มีส่วยช่วยในการเสริมสารอาหารแบะช่วยต้านการเกิดปฎิกิริยาออกซิเดชันเนื่องจากไขมัน จึงมีศักยภาพในการนำไปใช้ผลิตจริง กากกาแฟจึงนับเป็นวัตถุดิบที่มีคุณลักษณะดังกล่าว งานวิจัยนี้จึงใช้กากกาแฟในการเสริมอาหารให้กับแครกเกอร์ ด้วยกากกาแฟมีใยอาหาร มีสารประกอบโพลีฟีนอลดและยังเป็นการใช้ประโยชน์จากส่วนเหลือการชงกาแฟ ได้อย่างมีประสิทธิภาพ

The purpose of this invention is to develop a forest fire prevention agent that has the ability to prevent long-term forest fires, not only to suppress forest fires or prevent forest fires from spreading widely, but to prevent them from starting to catch fire from the beginning. It can prevent forest fires comprehensively and can be prevented for a long time during the peak forest fire period or the dry season, which is about 3-4 months. There are no residues or minimal residues without causing harm to the surrounding environment under the specified standards. Emphasis is placed on the use of raw materials, equipment, and chemicals that can be easily found in Thailand. This includes using the value of production costs as low as possible. This makes it suitable for use in large quantities for spraying and protecting forest areas in forest areas that are prone to fire. Estimated average for pollution caused by forest fires include particulate matter (PM), including PM2.5, PM10, carbon monoxide (CO), carbon dioxide, carbon dioxide, and carbon dioxide, Nitrogendioxide, VOC etc.

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.
