Members of Pineapple Leaf Group have gathered to produce paper from pineapple leaves left from pineapple harvest. The obtained paper has been used to make various types of products such as picture frames paper bags envelopes flowers key chains and so on for selling to visitors at tourist destinations and to those who came to observe the group’s production of paper and other local goods. However it is found that the product is not of much interest for the tourists as it should be. For this reason the researcher considers seeking appropriate solution to the group by using the pineapple leaves to make bas-reliefs with an aim to add value to pineapple leaf paper. From the creation of mold made of plaster and that made of resin and use both molds to make bas-reliefs it is found that the bas-reliefs obtained from resin mold are more beautiful and easier to produce. This is because resin mold is more durable clearer and lighter. The researcher has presented the bas-reliefs to 448 tourists who have come to visit the project during the period of one year and asked for their opinions and satisfactions. The results are that most of the respondents (327 persons) are female which accounts for 72.99% of all. Most of them or 352 persons (78.57%) obtain the secondary school diploma. The age range of most of the respondents (154 persons) is 31-40 years amounting to 34.38%. As for satisfactions of the quality of bas-reliefs made from pineapple leaves most of the respondents (72%) expressed “strongly agreed”. 75% of the respondents are “strongly agreed” with the product beauty. In terms of durability most of the respondents (61%) are “strongly agreed”. Concerning appropriateness of the product as souvenir most of the respondents (77%) expressed “strongly agreed”. Finally 73% of the respondents are “strongly agreed” with the idea that the product is potential for sale.

This research had a main purpose for studying the utilization of water hyacinth as the key component of paper production mixed with the agricultural waste as pineapple leaves and leaf sheath of banana tree. The paper pulps were prepared from 5 g/l NaOH at 90-95oC for 3 hours then bleaching with 5 g/l Hydrogen peroxide at 90-95oC for 30 minutes. The whole pulps were detached improvement with 5g/l Acramine 3187 before paper establishment production. Finally the strength of obtaining papers was consideration and competition to any craft paper type. As the results the appropriate ratio of paper was 70% water hyacinth (stem) 10% pineapple leaves and 20% leaf sheath of banana tree. It had 31.19 kN/m2 for bursting strength tearing strength as 309.17 mN and 0.49 mm thickness. The basis weight was 183±5 g/m2. The achieved paper was equivalent as KI craft paper. It was presented for packaging boxes and other procedures.

The study of utilizing core pineapple and phufa tea in drinking jelly. The purpose of this study and processing in add fiber from core pineapple wasted and Phufa tea in drinking jelly. The resulfs showed that formulation of carageenan was 10 gram because texture had elastic and softness appropriate. Ratio core pineapple juice : Phufa tea was 60 : 40 percentage had sensibility in color order and flavor for Phufa tea and add fiber from core pineapple was 10 gram because texture had elastic softness and easily suck. The consumer acceptability indicated of target consumer accepted the product. Consumer accepted like very much 41% and interested to buy product 83%. The physical attributes were as follows : L* a* b* value 75.20±0.01 1.31±0.01 28.43±0.02 and respectively Aw = 0.973±0.00 and hardness 5.42±0.45 (N). The chemical analysis of product contained pH = 3.52±0.02 Total soluble solid (TSS) = 15±0.00 (°Brix) and crud fiber content 0.602%. The microorganism (TPC) < 10 cfu/g. and yeast and mold < 10 cfu/g.

The study of Khanom Sommanat supplemented with dried pineapple cores revealed that the scraping was the most accepted for its appearance color aroma taste texture and overall liking. The average score is 6.92 6.88 7.27 7.26 7.00 and 7.38 respectively. Due to better grinding the texture is better than spinning and slicing the pineapple. The scrape was added to the Khanom Sommanat found that when added pineapple dried core at 10% of baked coconut. Most recognized for their appearance color flavor texture and overall taste. The scores were 7.20 7.18 7.32 7.35 7.32 and 7.36 respectively. The color L * (brightness) increased but the color a * (red) and the color b * (yellow) decreased. The hardness and crisp increase in weight 100 grams the nutritional value decreased. Carbohydrates protein ash fat but fiber content increases. The study on consumer acceptance of Khanom Sommanat supplemented with dried pineapple cores. It was found that the adoption of the product at 97 percent to the level of feeling. The mean score of 7.57 was moderate. Shelf life can be eaten at room temperature for at least 4 weeks in accordance with Thai dessert community product standard.

Recently Baan Pasang Wiwat Pineapple Leaf Community Enterprise Nanglae Sub-district Muang District Chiangrai has used a spherical cooking stove made of stainless steel to cook pineapple leaves. The cooking capacity was 40-50 kilograms each time and the cooking time was approximately 4 hours. The fuel was wood which was used for about 50 kilograms during the whole cooking process. The researcher has thought of saving the quantity of wood burned for coking by designing a new stove which would function like a charcoal kiln. It was a closed stove which would be automatically closed when the wood changed to charcoal to prevent the oxygen from entering. Then the fire would be put out and only the charcoal remained. The experimental result was that the minimum quantity of wood could be used to cook 10 kilograms of pineapple leaves and the process took 3.5 hours. However it is still difficult to find wood for use as fuel because it is rare and expensive. To solve such problem the researcher has developed and designed a pineapple leaf cooking stove which uses rice hulls as fuel. Rice hulls are easy to find and cheap so it is perfect for use as alternative fuel. In addition the size of the newly developed stove fits is suitable for completely cooking pineapple leaves by using one lot of rice hulls. After boiling 50 kilograms pineapple leaves with the stove powered by rice hulls by adding an amount of 21 kilograms of rice hulls the result was that the boiling time reduced from 4 hours to 1.5 hours. The cost of rice hulls used for each boiling was only 7.50 baht.
