The addition of more than 0.25% AG stabilizer in the dough was able to produce good quality JV in the aspects of physical characteristics and total solids with a preferred texture.Keywords: Arabic gum; jackfruit; stabilizer; velva

Sensory and Nutritional Characteristics of Concept Frozen Desserts Made from Underutilized Sweetpotato Roots

A traditional dairy-based frozen dessert (ice cream) was developed with three levels of sweetpotato (Ipomoea batatas) puree [20%, 30%, and 40% (by weight)] to determine the impact of sweetpotato content on product functionality, nutritional content, and sensory characteristics. Increased sweetpotato puree resulted in increased orange color, flavor intensity, and sweetpotato flavor, but 40% puree proved difficult to incorporate into the mixture. Additionally, nondairy frozen desserts containing 30% sweetpotato puree were compared with a milk-based control in which all ingredients were the same except that milk was replaced with soy (Glycine max) and almond (Prunus dulcis) milk. Consumer acceptability tests were conducted with panelists at Mississippi State University (n = 101) and in Pontotoc, MS (n = 43). Panelists in Pontotoc rated the overall acceptability of all three frozen desserts the same, but they preferred the appearance of the milk-based frozen dessert over that of soy- and almond-based milk alternatives. According to the panelists at Mississippi State, the milk-based frozen dessert had greater overall acceptability and aroma than the almond-based dessert and a preferential texture and appearance compared with the soy- and almond-based desserts. Milk-, soy-, and almond-based frozen desserts were rated as “slightly liked” or better by 92%, 80%, and 69% of the panelists, respectively.

A Novel Dairy Fermented Frozen Dessert with Honey and Pomegranate Juice: Physicochemical, Rheological and Sensory Properties

The effect of fat content and added yoghurt, honey and pomegranate juice concentration on the overrun, and the physicochemical, rheological and sensory properties of frozen yoghurt samples was investigated, aiming in the production of a novel low-fat and functional dairy fermented frozen dessert. For this purpose, the methodology of mixture experiment was applied to twenty samples, while a control sample (without using honey and pomegranate juice) was also produced. According to the results, the increase in yoghurt concentration resulted in increasing pH, overrun, brightness, elastic modulus (G&acute;) determined at -2 &deg;C and sensory hardness of the samples, while it reduced color parameters a* and b*, creaminess, sweetness and fattiness. Increasing honey concentration reduced lactic acid concentration, G&acute; at -2 &deg;C, hardness, sensory acidity, and to a lesser extent pH, while increased color parameter b*, overrun, sensory color intensity, creaminess, sweetness, and fattiness of the samples. The increase in pomegranate juice concentration resulted in decreasing pH, brightness and b*, as well as increasing a*, color intensity, creaminess and sensory acidity. Finally, fat, by interacting with one or two of the three constituents (yoghurt, honey and pomegranate juice), decreased pH, creaminess and fattiness, while increased lactic acid concentration, b*, color intensity and to a lesser degree the overrun level of the samples. Overall acceptability of the samples indicated that it is possible to use honey and pomegranate juice in the production of low-fat frozen yoghurt with favorable sensory properties.

Abstrak.. Velva adalah salah satu frozen dessert (makanan beku) yang banyak digunakan sebagai makanan pencuci mulut dimana bahan bakunya terdiri dari buah atau sayur. Pada pembuatan ini, kombinasi wortel-jeruk dipilih karena wortel termasuk salah satu sayuran sumber β-karoten dan mengandung vitamin A. Sedangkan penambahan sari jeruk untuk mengurangi bau langu pada wortel. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) dengan pola non faktorial. Faktornya adalah jenis penstabil (J) yang terdiri dari 3 taraf yaitu J1 = CMC, J2 = karagenan dan J3 = gelatin. Rancangan ini menggunakan satu faktor yang terdiri dari 3 taraf dengan menggunakan 3 kali ulangan sehingga akan diperoleh 9 satuan percobaan. Analisis yang dilakukan terhadap velva wortel meliputi overrun, daya leleh, organoleptik (hedonik), total kalori dan β-karoten. Pada setiap perlakuan berpengaruh sangat nyata dan nyata sehingga perlu dilakukan uji lanjut (DMRT). Hasil penelitian menunjukkan bahwa pada overrun dan daya leleh saling berkaitan yaitu semakin tinggi overrun pada velva maka semakin rendah daya leleh yang dihasilkan. Pada uji organoleptik semakin tinggi konsentrasi penstabil yang ditambahkan pada velva wortel pada setiap perlakuan maka akan memberikan pengaruh terhadap kelembutan dan warna velva wortel yang dihasilkan. Karakteristik fisik yang dihasilkan yaitu overrun berkisar 4,98 – 13,18% dan daya leleh berkisar 5,18 – 9,28 menit/g. Uji organoleptik (hedonik) yang dihasilkan yaitu tekstur berkisar 2,91 – 4,33 (tidak suka – suka). Karakteristik kimia yang dihasilkan yaitu total kalori 67,8 kkal/g (velva rendah kalori) dan β-karoten 1.528,79 µg/g.(Production Of Carrot (Daucus carota L.) - Orange (Citrus sinensis) Velva With Variations Of Stabilizers (CMC, Caragenan and Gelatin))Abstract. Velva is one of frozen dessert (frozen food) which is widely used as a dessert where the ingredients consist of fruit or vegetables. In this preparation, a combination of carrots is chosen because carrots are one of the vegetables which are sources of β-carotene and contain vitamin A. While the addition of orange juice to reduce the smell of unpleasant carrots. This research was conducted using Randomized Block Design (RBD) with a non factorial pattern. The factor is the type of stabilizer (J) which consists of 3 levels, namely J1 = CMC, J2 = carrageenan and J3 = gelatin. This design uses one factor consisting of 3 levels using 3 replications so that 9 units will be obtained. Analysis carried out on carrot velva includes overrun, melting power, organoleptic (hedonic), total calories and β-carotene. Each treatment has a very real and real effect so further testing (DMRT) is needed. The results showed that the overrun and melting power were interrelated, namely the higher the overrun of the velva, the lower the yield power produced. In the organoleptic test the higher the stabilizer concentration added to the carrots velva in each treatment will give effect to the softness and velva color of the carrots produced. The physical characteristics produced were overrun ranging from 4.98 - 13.18% and melting power ranged from 5.18 - 9.28 minutes / g. The resulting organoleptic (hedonic) test is texture ranging from 2.91 - 4.33 (dislike - like). The chemical characteristics produced are total calories 67.8 kcal / g (low calorie velva) and β-carotene 1,528.79 µg/ g.

Effects of Soymilk and Milk Solid not Fat on Soy Ice Cream Quality

Soy ice cream is a vegan friendly frozen dessert prepared using soymilk as the major ingredient. Nine formulations of soy ice cream were prepared with varying levels of soymilk (0-100%) and milk solid not fat (MSNF) (10-12%). From sensory evaluation, 50% soymilk and 12% MSNF resulted the best ice cream of all the formulations. From response study, it was found that the overrun was positively affected but melting rate was negatively affected by soymilk whereas both the overrun and melting rate were negatively affected by MSNF and the formulation of 100% soymilk and 10% MSNF was found to be the best optimized. Chemical analysis of the best product (50% soymilk and 12% MSNF) showed 64% moisture, 10% fat, 5.6% protein, 18.9% total sugar and 0.4% ash. Hence, soy ice cream can be prepared by using milk (50%), soymilk (50%) and MSNF (12%) with physical, chemical and sensory qualities similar to that of plain ice cream.
