 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Development of Holy Basil Storage Using Low Temperatures and Modified Atmosphere Packaging) ผู้เขียน: ทศพล เนียมทอง,  ดร.สุขเกษม สิทธิพจน์, ผู้ช่วยศาสตราจารย์ , ดร.วาณี ชนเห็นชอบ, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractHoly basil (Ocimum sanctum L.) is an herbal produce which rapidly deteriorates after harvesting, thus giving a short shelf life. Different levels of low temperature storage in combination with modified atmosphere packaging were used in this study to extend its shelf life. Holy basil branches of 80 g were packed in 4 different types of bag: a commercial polypropylene film with perforated holes and 3 other various oxygen permeability films, which are very high (PE-3), high (PE-2) and medium (PE-1). All packed sample were stored at 5, 10 and 25?C, then randomly sampled on day 3, 7, 11 for quality checking. The results showed the holy basil stored at 5?C faced with a rapid and severe chilling injury symptom; exhibited by browning spots and water soaking area. At the 25?C storage, basil yellowing and weight loss were very rapid due to high dehydration rate. The optimal temperature for storing holy basil was 10?C. Polypropylene films with holes contribute to faster weight loss and shorter shelf life than the other three packages. Oxygen remained in head space of PE-3, PE-2 and PE-1 bags were found at 18%, 17%, and 11%, respectively while carbon dioxide also were found at 0.7%, 0.8% and 1.8%, respectively. Modified atmosphere packaging at 10?C was found to be able to keep holy basil at a satisfactory quality for 9 days. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Development of Consumer Packaging for Fresh Persimmons) ผู้เขียน:Siriwan Tungsangprateep, รัชนีวรรณ กุลจันทร์, Wasan Toonkham, นายโอฬาร ตัณฑวิรุฬห์ , นางวีระศรี เมฆตรง , Bussakorn Praditniyakul, Pattra Maneesin, Sakkhee Sansupa สื่อสิ่งพิมพ์:pdf AbstractThe consumer packages for fresh persimmons were developed according to the packaging requirements of the produce characteristics, produce developers, as well as market requirements with the aims of decreasing produce damage during transportation and improving sale promotion. The new die-cut style corrugated fibreboard boxes for containing eight persimmons were developed with inside dimensions of 310?175?60 mm. In addition, special partitions were placed inside to avoid produce shifting during transportation, together with ventilation holes help to prevent excess moisture content. The E flute - corrugated boards type DP310/CA125/KI125 were selected as packaging materials due to their low water absorption. The water absorption value was about 117 g/m2 which was within the suitable ranges for fresh produce packaging. Foam net was used to wrap around each fruits to reduce impact and ensure tight packing of inside fruits during transportation. Besides its distinguish shape from the conventional packaging, all functional properties were also maintained e.g. containment, protection and sale promotion. The compression strength of the developed boxes was found to be 272 kgf providing enough strength to withstand occurring stress and pressure during storage, handling and transportation. In addition, the graphic design was developed in accordance with the structural design and consumer perceptions. |
