Kualitas tempe ditentukan oleh mikroorganisme yang berperan selama proses fermentasi berlangsung. Mikroorganisme utama dalam fermentasi tempe adalah Rhizopus spp. yang sekarang umumnya berasal dari salah satu jenis laru komersial. Akibatnya, keragaman Rhizopus spp. yang digunakan pada fermentasi tempe mengalami penurunan. Oleh karena itu, penelitian ini bertujuan untuk mendapatkan informasi tentang peran beberapa galur R. microsporus yang berasal dari “laru tradisional” dalam menentukan kualitas tempe. Tempe diproduksi menggunakan R. microsporus TB 23 (Tempe TB 23), R. microsporus TB 32 (Tempe TB 32), R. microsporus TB 51 (Tempe TB 51), R. microsporus TB 55 (Tempe TB 55) dan tempe menggunakan laru komersial (Tempe K). Kualitas tempe ditentukan melalui pengukuran tekstur, warna, cita rasa, aktivitas antioksidan, dan komposisi kimia (kadar air, kadar lemak, kadar protein, dan kadar serat kasar). Hasil penelitian menunjukkan bahwa tekstur, warna, dan cita rasa dari Tempe TB 23, Tempe TB 32, dan Tempe TB 55 sama dengan Tempe K. Demikian juga komposisi kimia Tempe TB 23, Tempe TB 32, dan Tempe TB 55 hampir sama dengan Tempe K.  Namun aktivitas antioksidan ketiga jenis tempe tersebut lebih tinggi dibandingkan dengan Tempe K. Tekstur, warna, dan komposisi kimia Tempe TB 23, Tempe TB 32, dan Tempe TB 55 bersama dengan Tempe K memenuhi syarat mutu tempe yang ditetapkan di Indonesia, yaitu yang tertera pada SNI 3144:2015. Oleh karena itu kesimpulannya adalah R. microsporus TB 23, R. microsporus TB 32, dan R. microsporus TB 55 memiliki potensi untuk dikembangkan sebagai laru komersial untuk fermentasi tempe.The Role of Some Strains of Rhizopus microsporus Originating from “laru tradisional” in Determining Tempe Quality AbstractThe quality of tempe was determined by involved microorganisms. The main microorganism in tempe fermentation is Rhizopus spp. which now generally comes from one type of commercial laru. As a result, the diversity of Rhizopus spp. in tempe has decreased. Therefore, this study aims to obtain information about the role of several strains of R. microsporus originating from "laru tradisional" in determining the quality of tempe. Tempe was produced using R. microsporus TB 23 (Tempe TB 23), R. microsporus TB 32 (Tempe TB 32), R. microsporus TB 51 (Tempe TB 51), R. microsporus TB 55 (Tempe TB 55), and tempe using commercial laru (Tempe K). The quality of tempeh was determined through measurements of texture, color, taste, antioxidant activity, and chemical composition (moisture content, fat content, protein content, and crude fiber content). The results showed that texture, color and taste of Tempe TB 23, Tempe TB 32, Tempe TB 55 were similar as compared to Tempe K. The antioxidant activity of the three types of tempe was higher than Tempe K. The chemical composition of the three types of tempeh was almost similar compared to Tempe K. Texture, color and chemical composition of Tempe TB 23, Tempe TB 32, Tempe TB 55 and Tempe K has fulfilled the quality requirements of tempe in Indonesia, which were listed in SNI 3144: 2015. Therefore, R. microsporus TB 23, R. microsporus TB 32 and R. microsporus TB 55 may be developed as commercial inoculums for tempe fermentation.

ABSTRACT: Meloidogyne javanica is a plant-parasitic nematode that infects a wide range of vegetables. Its negative effects on crop yield and value are well documented. However, few studies have investigated the impact of the parasite on the nutritional value of vegetables. This study aimed to assess the effect of M. javanica parasitism on the vegetative characteristics, nematological parameters, chemistry composition and antioxidant activity of carrots. Seedlings were inoculated with 0 (control), 1000, 2500, or 5000 eggs and eventual second-stage juveniles (J2) of M. javanica. At 60 days after inoculation, plants were harvested and evaluated. Plants inoculated with 2500 eggs and J2 of M. javanica had higher root and tuber fresh weight than the control. Gall number increased with increasing inoculum density. The number of nematodes in the roots increased until 3000 specimens, decreasing thereafter. Proximate analysis revealed that plants inoculated with 1000 eggs and J2 of M. javanica or more had higher protein content in roots. In contrast, inoculation with 1775 nematodes or more resulted in a decrease in carotenoid content. There was no effect of inoculation on total phenolic content or antioxidant activity. Although, M. javanica infection did not have a marked impact on the nutritional quality of carrots, gall formation resulted in deformed roots of low commercial value.

Artisanal cheeses made with raw milk are highly appreciated products in Brazil. Most of these cheeses are produced in small facilities across different production regions in the country, some of which have been granted a protected designation of origin and are award winners. The most prominent state that manufactures these products is Minas Gerais (MG), but production is also gaining strength in other Brazilian states. The major challenge faced by artisanal cheese production is related to microbial risks associated with foodborne pathogens when the quality of the raw milk is unsatisfactory. Regulations created for the dairy industry are constantly been revised and adapted, considering the small-scale production of Brazilian artisanal cheeses, in order to guarantee safety at all steps of cheese production and commercialization. This text presents a summary of the huge diversity of artisanal cheeses produced in the country, grouped by geographical regions, and reviews the current challenges faced by producers and government considering the safety of these cheeses.

This study aimed to develop a novel biscuit by supplementing cladode flour (CF) into whole-wheat flour (WWF) at different proportions 0, 25, 50, 75, and 100%. Proximate analysis revealed that CF had a high amount of ash (11.9%) and dietary fiber (41.04%). Major minerals determined by ICP-MS were calcium (4.47 g/100 g); potassium (1.25 g/100 g); magnesium (1.46 g/100 g); and trace elements such as zinc (1.77 mg/100 g), copper (0.95 mg/100 g), and selenium (148.5 μg/100 g). The analysis of total phenolics, total flavonoids, and antioxidant activity showed high values (649.88 mg gallic acid equivalents (GAE)/100 g; 399.16 mg catechin equivalent (CE)/100 g; and 72.37%, respectively). HPLC was used to identify four phenolic acids (gallic, ferulic, syringic, and caffeic acids) and only one flavonoid (rutin) in cladode flour. Biscuit hardness, L∗, and a∗ color values decreased corresponding to the incorporation level of CF. Sensory evaluation showed that the substitution level (up to 25%) is ideal to prepare an acceptable bio-biscuit. Cladode flour could be very useful for the food industry as a source of bioactive compounds with technological potential and nutritional and antioxidant properties.

The production of tchapalo remains more or less an empirical process. For the improvement of the product quality, there is a need of more knowledge on this traditional process and the beer characteristics. The alcoholic fermentation is one of the most steps which most determines the quality of the beer. In this study, the characteristics of the traditional starter and the evolution of temperature, ethanol, sugars and organic acids were assessed at small-scale production during alcoholic fermentation of tchapalo. Brewers used traditional starter at the rate of 0.76-0.88 % when it was dried or at 2.38 % when it was not. When the wort was at 36.6-39.3 °C, the starter was added to initiate the fermentation. Temperature decreased to 34.6-36.5 °C at the end of the fermentation which was concluded after 7.6 h to 8.4 h. Sugars were consumed during the fermentation but it remained 12.9 to 16.57 g/L of reducing sugars and 8.02 to 9.12 °Brix of TSS in the final product. Ethanol content increased from 0.02-0.35 % (v/v) in the wort to 3.5-4.59 % in the beer. The oxalic, citric, tartaric, malic, lactic, fumaric and propionic acids were found in the wort and in tchapalo and increased or decreased during fermentation differently from one site to another. But, the acetic acid was not always detected in both the wort and the beer.

In this work, to reduce the cost of production of parts using injection molding metal technology (MIM technology), it is proposed to use additive technologies (AT) for the manufacture of green parts. The use of AT allows us to abandon expensive molds and expand the field of use of the MIM of technology in single and small-scale production. For manufacture of green parts, the technology of manufacturing fused filament (Fused Filament Fabrication – FFF) is offered. The original composition of the metal powder mix (feedstock) and the filament manufacturing modes for 3D printing have been developed for the FFF technology. The cost of filament is much lower than its analogs. The factors affecting the print quality of green part are considered. All factors are divided into two groups depending on the possibility of their change during printing. The research of the influence of the coefficient filament supply on the geometry of green parts during 3D printing is presented.
