Abstract

Manggis merupakan salah satu hasil pertanian utama penyumbang devisa tahunan terbesar dari buah-buahan. Manggis menempati urutan pertama ekspor buah segar nasional ke mancanegara. Kulit buah manggis mengandung senyawa aktif yang disebut xanthone yang didapat melalui berbagai metode ekstraksi. Perbedaan metode ekstraksi berpengaruh terhadap kualitas senyawa xanthone. Ekstraksi kulit manggis dapat dilakukan dengan metode konvensional dan non-konvensional. Kualitas ekstraksi senyawa xanthone dapat diukur melalui parameter rendemen, total xanthone, total alpha-mangosteen, total fenol dan nilai IC50. Metode ekstraksi menggunakan soxhlet dan maserasi adalah metode yang paling banyak digunakan pada ekstraksi kulit manggis. Metode non-konvensional memberikan hasil yang lebih baik dibandingkan dengan metode konvensional pada parameter rendemen, total xanthone, total alpha-mangosteen, total fenol dan nilai IC50.

Abstract

Recently, the rising incidence of natural catastrophe has increased the disaster preparedness, aiming to mitigate its devastating effect. Developing an emergency food is one of meaningful attempts to rise the preparedness. This research aimed to determine the best formula of ready-to-eat rice in retort pouch packaging accepted by consumers, and to determine the operating time to reach a lethality value (F0) to meet the commercial shelf-stable food requirements as an emergency food. The thermal process adequacy (F0) was used to determine the commercial shelf-stable products according to Indonesian regulation. The results showed that the determination of ready-to-eat rice was dependent on the ratio of rice and water. The most accepted product was determined according to quality attributes and organoleptic tests applied to meet the criteria for emergency food, namely color, flavor, and texture and best perceived by consumers. A formula with 140 g of half-cooked rice and 60 g of water was attributed to the best sample, having hardness of 7305.45 gf, elasticity of 36.40%, gumminess of 2185.720 gf, and adhesiveness of -167.975 g.s. In terms of microbiological quality, the TPC for the half-cooked rice sample reached 7.2×107 CFU/mL, while cooked rice in retort pouch packaging was <25 CFU/mL. Using heat distribution curve, heating at 110°C produced a come up time (CUT) after 40 min. Furthermore, the F0 value was 4.12 which was in accordance with the Indonesian regulation.

Abstract

The peel of mangosteen (Garcinia mangostana L.) constitutes a larger proportion of the fruit in comparison to its flesh. The peel extract product manufactured by nutraceutical industries does not require using the fruit flesh. To increase the shelf life and value of the product, the development of a mangosteen powder drink can be carried out. Therefore, this research aims to determine the characterization of initial raw materials and factors influencing consumer preferences for instant mangosteen powder drink to improve the acceptance of the product. The data collected were analyzed through descriptive statistics and the chi-square test. Furthermore, the chi-square test showed that demographic regions affected mangosteen fruit price, the level of preferences for the powder drink, consumption time, as well as feelings and interests of potential customers. The results of the Total Plate Count (TPC), Total Yeast and Mold Count (TYMC), and coliform microbiological test conducted on mangosteen purée raw materials met the quality requirements established by National Standardization Body (NSB) for fruit purées.

Abstract

Mangosteen (Garcinia mangostana L.) has become the main agricultural products contributing to the largest annual foreign exchange from the fruit category. Mangosteen rind contains xanthone compounds as a source of antioxidants, with α-mangostin and γ-mangostin, as the main components which are used as traditional and modern ingredients to treat various diseases. However, mangosteen rind extract has low bioavailability thus resulting in low effectiveness in the application. This study aimed to find the ideal formulation for producing the extract and nanoemulsion of mangosteen peel. The research carried out in two stages: extraction of mangosteen peel and production of nanoemulsion. Ethanol 70% was the best for mangosteen rind extraction, with a percentage yield of 40.96±0.51%, antioxidant activity of 5708.33±159.57 µg AEAC/mL sample, and total xanthones of 373.84±6.49 µg/mL sample. The use of Tween 20 at nanoemulsion production gave the best test results, with particle size of 10.58±1.25 nm, polydispersity index 0.27±0.03, zeta potential -2.34±0.46 mV, and total xanthones 35,28±0,04 µg/mL sample.

Abstract

Ubi Banggai merupakan ubi lokal yang banyak dibudidayakan dan dikonsumsi di Kepulauan Banggai Sulawesi Tengah. Ubi Banggai banyak mengandung karbohidrat, terutama pati. Pati ubi Banggai mengandung amilosa yang tinggi yang sesuai untuk bahan baku pembuatan sohun. Penelitian ini bertujuan untuk mengoptimasi proses pembuatan sohun pati ubi Banggai (Dioscorea Alata). Pati Banggai dari tiga varietas (Baku Pusus, Baku Tuu Oloyo dan Baku Boan) diekstraksi dan diproses menjadi sohun. Optimasi proses dilakukan dengan menggunakan pati Baku Pusus. Sohun dibuat dengan mencampurkan pati ubi Banggai dengan air, dilewatkan dalam ekstruder ulir tunggal dan dikeringkan. Sepuluh kombinasi percobaan yang memvariasikan persen air (50-60% dari berat pati) dan suhu barrel (95-100oC) dirancang dengan response surface methodology. Optimasi proses berdasarkan parameter kehilangan padatan akibat pemasakan (KPAP), daya serap air dan elongasi. Proses optimum pembuatan sohun adalah kombinasi air (61%) dan suhu barrel ekstruder (99oC). Sohun memiliki KPAP 6.16% KPAP rendah, dan daya serap air dan elongasi tinggi (278.08% dan 236.95%). Dibandingkan sohun dari pati Baku Puyus, sohun pati Baku Tuu Oloyo dan Boan yang diproses pada kondisi proses menunjukkan KPAP lebih tinggi (7.12% dan 8.54%), daya serap air (204.05% dan 201.90%) dan elongasi (310.94% dan 320.70%) yang lebih rendah. Ketiga sohun menunjukkan sifat translusen dan berwarna keabu-abuan.

Abstract

Bay leaves (Sygygium polyanthum), kaffir lime leaves (Citrus hystrix) and pandan leaves (Pandanus amaryllifolius) are herb leaves with unique aroma that are often added to dishes to strengthen and enrich the taste. The high demand of the leaves has prompted efforts to make them easy to distribute and shelf stable. Drying can increase the shelf life of these leaves with acceptable quality. The objectives of the research were to determine drying models for these leaves using two types of driers and to determine the panelist's preference for the dried and rehydrated leaves. These herb leaves are fresh-picked from the tree, cleaned and dried using the two different driers, i.e. fluidized bed drier (temperature 40-42°C) and tray drier (temperature 58-61°C). The leaves were weighed every 15 minutes until they reached a constant weight. Fresh leaves and dry leaves were photographed. The drying kinetics of both types of driers were checked with the Lewis model and Page model. Panelist preference test was carried out on dry leaves and leaves that had been rehydrated using hot water. The results showed that drying with a tray drier was able to dry faster than that with a fluidized bed drier. The Page drying model is more suitable to describe the drying conditions than the Lewis drying model. Panelists preferred dry and rehydrated herb leaves obtained from fluidized bed drying.

Abstract

Flavors play a role as a determinant of the acceptability of food product. Halal certificate is a required document in Indonesia. Halal material requirements refer to SK11/Dir/LPPOM MUI/VI/20. This study aimed to obtain a profile of halal critical flavoring materials in BPOM regulation no. 13/2020 based on the document requirements for halal materials in LPPOM's SK11 and propose for non-critical halal flavoring materials. Materials used in this study were data-from BPOM regulation no. 13/2020, halal material requirements SK11/Dir/LPPOM MUI/VI/20 and other literatures associated with material production process information. The research method includes data collection based on CAS numbering, determination of BPOM flavoring materials outside the list of non-critical halal materials, determination of the production process for flavoring material, mapping of halal critical flavoring materials. The results showed that 53.82% (1381/2566) of the flavoring materials in BPOM regulations were halal critical materials. Based on identification results there were 26 types of production processes that have different halal critical sources that affect the required halal supporting documents. 65.38% (17/26) of critical halal sources came from raw materials, 30.77% (8/26) critical halal sources came from raw materials and manufacturing processes. The criticality of halal flavoring materials depends on the source of the raw material and the production process. Flavors obtained from the chemical synthesis process (414/1381) can be proposed as non-critical halal flavorings.

Abstract

The yuzu product development process in general was related to the level of consumer preference or acceptance which could not be separated from the sensory aspect. The purpose of this study was to obtain a map of the sensory profile characteristics of the ideal product, to identify the sensory and emotional profile characteristics, as well as to observe the correlation between sensory attributes and preference for yuzu drink based on consumer perceptions. The methods used included consumer surveys, ideal profile methods, and check-all-that-apply (CATA) as consumer-based methods. The consumer survey involved 108 respondents to assess general consumer preferences. The sensory evaluation panel consisted of 47 consumer panelists. The samples for sensory evaluation included 4 commercial yuzu beverage products available in Jakarta. The results of ideal profile mapping for yuzu beverage products with codes A, B, C, and D indicated that product A closely matched the ideal sensory profile, with sensory attributes of sweetness, acidity, freshness, citrus, and bitterness. The yuzu drink samples with codes A and C provided the same distinctive sensory attributes both in the mouth and upon swallowing, with their respective distinctive attributes being sweetness and freshness. The sweetness and freshness were correlated with consumer preferences (overall liking) when the product was in the mouth, and the freshness was correlated with preferences when the product was swallowed. The emotional profile mapping results revealed that consumers favored products associated with the "pleasure" emotion as found in product A and "relaxing" emotion as found in product D.
