Process development of healthy snack products from germinated brown rice flour and banana flour using the extrusion process

Abstract

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.

Objective

ขนมขบเคี้ยวส่วนใหญ่ทำจากแป้งและไขมัน ทำให้มีแคลอรี่สูง ในขณะที่ปริมาณโปรตีน แร่ธาตุ และสารออกฤทธิ์ทางชีวภาพค่อนข้างต่ำ การบริโภคขนมขบเคี้ยวอย่างต่อเนื่องและมากเกินไปอาจส่งผลกระทบต่อสุขภาพ ดังนั้น การพัฒนาผลิตภัณฑ์ขนมขบเคี้ยวให้มีคุณค่าทางโภชนาการสูงขึ้นจึงเป็นเรื่องสำคัญ โดยสามารถทำได้ผ่านการปรับสูตรส่วนผสมโดยใช้วัตถุดิบที่มีคุณค่าทางโภชนาการสูง และการพัฒนากระบวนการผลิตที่ไม่ต้องทอด เช่น การใช้กระบวนการเอกซ์ทรูชัน การศึกษาในครั้งนี้จึงมุ่งพัฒนาผลิตภัณฑ์ขนมขบเคี้ยวจากแป้งข้าวกล้องงอกและแป้งกล้วยน้ำว้า ซึ่งมีคุณค่าทางโภชนาการและสารออกฤทธิ์ทางชีวภาพโดดเด่น พร้อมทั้งศึกษาสภาวะที่เหมาะสมของกระบวนการเอกซ์ทรูชันเพื่อให้ผลิตภัณฑ์มีคุณภาพและเป็นประโยชน์ต่อสุขภาพ ตรงตามความต้องการของผู้บริโภคในปัจจุบัน

TOOTHBRUSH APPEARANCE FACTORS THAT AFFECT BABY BOOMERS' PURCHASING DECISIONS

This study aims to identify the toothbrush appearance factors that affect baby boomers purchasing decisions. The research divide into three stages: The first stage is to classify the toothbrush appearance factors through a review of literature, research, and examining toothbrushes currently available on the market, summarizing them as appearance factors. The second stage is to summarize the results of the toothbrush appearance factors to create a multiple-choice questionnaire in three dimensions: purchasing decisions, aesthetics, and functionality. Collecting data from a group of 30 Baby Boomers aged 57-75 years old. The last stage is to summarize the three dimensions of appearance factors affecting baby boomers' toothbrush purchasing decisions and report as percentages and rank them. The research findings indicate that the most significant toothbrush appearance factor is a "Curved handle," accounting for 80%, followed by “Multi-level bristles” at 70%, a "Rubber thumb rest" at 53.3%, "Handle divided into more than two parts" at 50%, and “Offset shape” at 40%, respectively. In terms of the reason for purchasing decision based on various factors are as follows: the curved handle and offset shape give a sense of purchase with its aesthetic, While the selection of multi-level bristles, the Rubber thumb rest, and the handle divided into more than two parts due to functionality.

A Cold Cover for Raw Milk Transportation

This study was conducted to develop a prototype cooling cover for transporting raw milk, aiming to provide a solution for maintaining the quality of raw milk during transportation to milk collection centers. The cooling cover is made using Phase Change Material (PCM), produced from water mixed with a gelling agent, in an amount of 5.6 kg, attached around an aluminum milk tank (with a capacity of 25 L). The cover is then covered with a UV-reflective fabric in two types: polyvinyl chloride (PVC) and high-density polyethylene (HDPE). The temperature reduction performance of both types of covers was evaluated by measuring water temperatures at various points along the radial and vertical directions of the milk tank at six points, using type-T thermocouples, under three environmental conditions: a constant temperature of 25 °C, 35 °C, and outdoor ambient temperature (average temperature 35.5 °C) for a minimum duration of 180 min. The experimental results revealed that at 120 min., the water in the tank covered with PCM-PVC and PCM-HDPE covers had temperatures lower than the ambient temperature by 12.6 °C and 12.9 °C, respectively, under a constant ambient temperature of 25 °C, and under a constant ambient temperature of 35 °C lower by 16.7 °C and 16.4 °C, respectively, and outdoor conditions. Since the temperature reduction performance of PCM-PVC and PCM-HDPE covers showed no significant difference, the performance of microbial quality preservation of raw milk was assessed only with PCM-PVC cover in comparison to a non-covered case (control), by measuring coliform and Escherichia coli counts using compact dry plates. Results indicated that after 120 min., milk in the tank covered with PCM-PVC had an average coliform count of 1.6 × 10^4 CFU/ml and E. coli count of 2 × 10^3 CFU/ml, which was lower than the non-covered control with an average coliform count of 1.5 × 10^4 CFU/ml and E. coli count of 1.1 × 10^4 CFU/ml. This study concludes that the temperature reduction achieved by the cooling cover can help inhibit coliform growth to levels below raw milk quality standards, demonstrating the potential of the cooling cover in maintaining the quality and safety of raw milk during transport, ultimately contributing to an improved quality of life for Thai dairy farmers.
