Mapping The Worldwide Knowledge of Jack Bean by A Bibliometric Approach

2024-03-15T04:16:23+00:00

Indonesia's indigenous inhabitants acknowledge the local legume plant known as jack bean. The Jack bean has various advantages, including increased production, a shorter lifespan, upright stems mimicking shrubs, and improved tolerance to biotic and abiotic stresses. Nonetheless, the jack bean plant is particularly vulnerable due to harmful compounds such as canavaline, choline, hydroziamine acid, trogonelin, and cyanide. A bibliometric study was performed to locate studies on jack beans. The data collection procedure includes executing an extensive search in Scopus-indexed journals using the keywords "Jack Bean." It could limit the search to the article abstract, title, keywords, and country. The articles included in this study were published between 2000 and 2023. The search yielded a total of 999 items. The data was obtained on September 10, 2023; any later alterations are not considered in this research. According to the published literature, over the last 23 years, many studies have been conducted to develop urease inhibition and antioxidants from jack beans. However, little research has been done into the functional benefits of jack bean bioactive components for enhancing bodily health, such as antidiabetic, antihypertensive, and anticancer properties. This article contributes to helping researchers fill jack bean-related research gaps and apply technology to the industrialization process of jack beans in the functional food and nutraceutical industries.

2024-03-07T05:31:25+00:00

Jack bean tempeh was processed into jack bean tempeh milk. The addition of Ajwa date can improve the organoleptic and nutritional value of jack bean tempeh milk. Moreover, stabilizers must be added while making jack bean tempeh milk to enhance its quality. This study contributed to determining the effect of various stabilizers on jack bean tempeh milk quality. The treatments were (F1) the addition of iota carrageenan stabilizer (0.1%), (F2) the addition of gum Arabic stabilizer (0.1%), (F3) the addition of pectin stabilizer (0.1%), and (F4) the addition of carboxy methyl cellulose (CMC) stabilizer (0.1%). The results of this study showed that the stabilizer types had no significant effect on the organoleptic color, texture, and taste of the jack bean tempeh milk. The selected formulation was based on the hedonic quality test in the parameters of color and aroma, namely formula F4, which was jack bean tempeh milk with the addition of a CMC stabilizer. The results of the chemical characteristics of F4 jack bean tempeh milk was protein content of 0.65%, fat content of 2.48%, and antioxidant activity (IC50) of 7760 ppm. The physical characteristics of F4 jack bean tempeh milk was a pH value of 5.8, total dissolved solids of 20.7°Brix, a viscosity of 13.43 cP, L* value of 60.61, a* value of -0.12, and b* value of 19.56.

2024-01-26T02:48:53+00:00

The edible film aims to improve the shelf life and safety of food by providing a physical barrier to external influences to prevent food deterioration. Arrowroot starch has high amylose content and excellent gelling ability, and it is massively produced in Indonesia. At the same time, glycerol has water-soluble and polar properties. So, studies were carried out on edible film based on arrowroot starch as the polysaccharide and glycerol as the plasticizer. This study was contributed to investigate the effect of the concentration of arrowroot starch (3, 4% w/v) and glycerol (1.25, 1.5, and 1.75% w/v) on physical properties (thickness by micrometer, functional group by FTIR, molecular structure surface by SEM) of edible film. The results showed that increasing the concentration of arrowroot starch and glycerol could increase tensile strength. Besides that, the formulations of 30% arrowroot starch with 12.5% glycerol and 40% arrowroot starch with 17.5% glycerol had the best tensile strength of 27.24 and 22.88 MPa, respectively. However, the results of the morphological analysis of the edible film on the arrowroot starch-glycerol formulation still contained pores and cracks.

The Substitution of Purslane Weed (Portulaca oleracea L.) Flour and Glucomannan Powder on Organoleptic and Proximate Test of Instant Noodles

Instant noodles are a food product that the public highly favors because of their diverse taste, easy presentation, and economical price. Instant noodles cannot be considered whole food because they do not meet the needs of balanced nutrition for the body. Purslane flour (Portulaca oleracea L.) contains macronutrients and micronutrients in the form of carbohydrates, protein, dopamine, potassium salts, tannins, saponins, vitamin A (β-carotene), Vitamin B, Vitamin C, nicotinic acid and natural antioxidants related to fatty acids omega 3 by 44.29%. This study contributed to compare the effectiveness of the substitution of Purslane flour and glucomannan powder on organoleptic test instant noodles. This study was an experiment with a completely randomized design of two-factorial with six treatments including the formulation of purslane flour 25%, 30%, and 35%, while glucomannan formulation of 5%, 10%, 15% with two temperature treatments, 50 °C, and 60 °C. We conducted an organoleptic test with statistical analysis t-test and descriptive. The substitution of purslane flour and glucomannan in instant noodles gave the best organoleptic characteristics in the K2S2 treatment (the formulation of 60% wheat flour, 30% purslane flour, and 10% glucomannan at a drying temperature of 60 °C) with proximate analysis content of 12.26% moisture, 5.53% ash, 5.13% fat, 13.91% protein, and 63.14% carbohydrates.

The Effect of Soaking Time and Size of Fruit Pieces on Pineapple Infused Tea Characteristic

2024-01-30T06:33:20+00:00

Fruit-infused tea become one of the exciting innovations in recent years. Fruit addition could improve the freshness and richness of tea drinks. Pineapple has good potency when used in the making of fruit-infused tea. The soaking time and size of fruit pieces were essential to determine because there is a solid-liquid extraction process in making pineapple-infused tea. This research aimed to assess the effect of soaking time and the size of fruit pieces on the characteristics of pineapple-infused tea. This research used Complete Block Design (CBD) with two factors: (A) soaking time and (B) size of fruit pieces. Factor A consisted of 3 levels: A1 = 3 hours; A2 = 6 hours; A3 = 9 hours. Factor B consisted of 3 levels: B1 = 0.5×0.5×0.5 cm; B2 = 1×1×1 cm; B3 = 1.5×1.5×1.5 cm. The treatment was replicated two times. The analysis was antioxidant activity, vitamin C, pH, total flavonoid, and tannin content. The result showed a significant difference in soaking time on tannin content, vitamin C, pH parameters, and the size of fruit pieces on pH parameters. The best result was obtained in 1×1×1 cm of fruit pieces and 3 hours soaking time with 13.20 ± 0.01% vitamin C, 17.28 ± 0.83% tannin content, 0.107 ± 0.018 % flavonoid content, 92.56 ± 1.99 % antioxidant activity and 4.95 ± 0.03 pH value. This research provides data about the difference between soaking time and the size of fruit pieces to the pineapple-infused tea characteristic.

Texture Profile Analysis of Lamtoro Gung (Leucaena leucocephala ssp. Glabrata (Rose) S. Zarate) Tempeh

2024-03-27T16:26:36+00:00

Lamtoro Gung seeds are low in fat content but rich in protein. Lamtoro Gung is often used as an alternative protein source. Lamtoro Gung is usually taken as a prepared meal containing grains and nuts. It is germinated and utilized in a variety of dishes, including the production of tempeh. However, nothing has been done to explain the textural profile of Lamtoro Gung tempeh, which is made by fermentation processes in various packaging materials such as plastic, banana leaves, and teak leaves. This study aims to evaluate the textural characteristics of Lamtoro Gung tempeh produced using different packaging materials and fermentation periods. This study contributes to understanding how packaging variations affect the texture of Lamtoro Gung tempeh. Tempeh made from teak leaf packaging and fermented for four days offered better texture profile hardness (195.38 N), cohesiveness (0.46), gumminess (81.57 N), and chewiness (54.99 N) higher than banana leaves; hardness (49.90 N), cohesiveness (0.29), gumminess (14.52 N), and chewiness (10.14 N) but similar to plastic; hardness (165.28 N), cohesiveness (0.45), gumminess (74.23 N), and chewiness (50.35 N). Therefore, packaging material impacts the texture profile of tempeh fermented from Lamtoro Gung seeds. Sensory evaluation of the tempeh would need to be investigated to check consumer acceptance of the product.
