A predicted metalloproteinase gene, HypZn, was cloned from Aspergillus niger CGMCC 3.7193 and expressed in Pichia pastoris GS115, and the physicochemical characteristics of recombinant HypZn were investigated after separation and purification. The results showed that the specific activity of the purified HypZn reached 1859.2 U/mg, and the optimum temperature and pH value of HypZn were 35°C and 7.0, respectively. HypZn remained stable both at 40°C and at pH values between 5.0 and 8.0. The preferred substrate of HypZn was soybean protein isolates, and the Km and Vmax values were 21.5 μmol/mL and 4926.6 μmol/(mL∙min), respectively. HypZn was activated by Co2+ and Zn2+ and inhibited by Cu2+ and Fe2+. The degree of soybean protein isolate hydrolysis reached 14.7%, and the hydrolysates were of uniform molecular weight. HypZn could tolerate 5000 mM NaCl and completely lost its activity after 30 min at 50°C. The enzymological characterizations indicated that HypZn has great application potential in the food industry, especially in fermented food processing.

Type 2 diabetes (T2D) is a complex metabolic disease, which involves a maintained hyperglycemia due to the development of an insulin resistance process. Among multiple risk factors, host intestinal microbiota has received increasing attention in T2D etiology and progression. In the present study, we have explored the effect of long-term supplementation with a non-dairy fermented food product (FFP) in Zucker Diabetic and Fatty (ZDF) rats T2D model. The supplementation with FFP induced an improvement in glucose homeostasis according to the results obtained from fasting blood glucose levels, glucose tolerance test, and pancreatic function. Importantly, a significantly reduced intestinal glucose absorption was found in the FFP-treated rats. Supplemented animals also showed a greater survival suggesting a better health status as a result of the FFP intake. Some dissimilarities have been observed in the gut microbiota population between control and FFP-treated rats, and interestingly a tendency for better cardiometabolic markers values was appreciated in this group. However, no significant differences were observed in body weight, body composition, or food intake between groups. These findings suggest that FFP induced gut microbiota modifications in ZDF rats that improved glucose metabolism and protected from T2D development.

<p>Tahu merupakan produk makanan yang paling banyak dikonsumsi oleh masyarakat Indonesia. Produksi tahu di Indonesia masih banyak menggunakan metode konvensional dengan limbah yang dihasilkan belum dimanfaatkan secara optimal. Limbah tahu mengandung senyawa organik dengan pH yang rendah dan merupakan salah satu penyumbang polutan pada lingkungan perairan apabila tidak dilakukan proses pengolahan terlebih dahulu sebelum dibuang ke lingkungan. Pengolahan limbah tahu dapat dilakukan dengan beberapa metode, seperti penambahan bakteri mikroorganisme efektif, plasma ozonasi, biogas dan produksi makanan. Potensi pengolahan limbah tahu menjadi produk yang lebih bermanfaat belum banyak dikenal masyarakat luas. Oleh karena itu diperlukan metode alternatif pengolahan limbah tahu yang lebih efektif dan efisien sehingga mudah diterapkan pada masyarakat. Beberapa pengolahan limbah tahu berpotensi menjadi pupuk organik cair, mengurangi kadar polutan sehingga lebih aman jika dibuang ke lingkungan, yang selanjutnya dapat menghasilkan biogas sebagai bahan bakar alternatif. Selain itu, limbah tahu dapat digunakan untuk produksi makanan seperti <em>Nata de soya, </em>tempe gembus, dan keripik</p><p class="Abstract"><strong>Tofu Waste Treatment and Its Potential. </strong><span lang="EN-GB">Tofu is a food product most consumed by Indonesians. Tofu production in Indonesia still uses conventional methods with the resulting waste which has not been used optimally. Tofu waste contains organic compounds with low pH and is a contributor to pollutants in the aquatic environment if it was not processed first before being discharged into the environment. Tofu waste treatment can be carried out by several methods, such as the addition of effective bacteria of microorganisms, plasma ozonation, biogas, and food production. The potential of tofu waste processing into a more useful product has not been widely recognized by the public. Therefore, it requires an alternative method of tofu waste treatment that is more effective and efficient so that it is easily applied to society. Some tofu waste treatment plants have the potential to become liquid organic fertilizer, reduce pollutant levels thus it is safer when released into the environment further used to produce biogas as an alternative fuel. In addition, it can be used for other food products such as Nata de soya, Tempe gembus (a traditional fermented food), and chips.</span></p><p> </p>

Tempeh is a fermented food from soybean seeds using the fungus Rhizopus oligosporus. Tempeh is usually made from ordinary fermented soybeans. However, there are various types of beans besides ordinary soybeans, one of which is black soybeans. Food product innovation is closely related to consumer acceptance. Acceptance can be measured using organoleptic test. Organoleptic testing is an important component in the process of making food product innovations. In this study, tempeh was made with a mixture of soybeans and black soybeans in a ratio of 50:50. The resulting tempeh was then tested organoleptically including the parameters of color, texture, aroma, and overall and compared with commercial tempeh on 45 panelists. Based on this research, it is known that the overall parameters, namely color, texture, aroma, and overall in soybean tempeh and 50:50 black soybeans have lower acceptability than commercial tempeh so that further development of these products is needed so that consumer acceptance is higher increase.

Optimization of food storage has become a central issue for food science and biotechnology, especially in the field of functional foods. The aim of this work was to investigate the influence of different storage strategies in a fermented food product (FFP) and further determine whether the regular storage (room temperature (RT) and standard packaging (SP)) could be refined. Eight experimental conditions (four different temperatures × two packaging) were simulated and changes in FFP’s microbial ecology (total bacteria, lactic acid bacteria (LAB), and yeasts) and physicochemical characteristics (pH and moisture content (MC)) were determined following 1, 3, 6, and 12 months. All conditions tested showed a decline in microbial content due to the effect of the temperature, 37 °C being the most detrimental condition, while −20 and 4 °C seemed to be better than RT in some parameters. Vacuum packaging (VP) only had a major effect on MC and we found that VP preserved greater MC values than SP at 3, 6, and 12 months. The correlation analysis revealed that total bacteria, LAB, and yeasts were positively associated, and also both pH and MC showed a correlation. According to our results and with the purpose to maintain the load of viable microorganisms, we observed that the best storage conditions should contemplate SP and freezing or cooling temperature during a period no longer than 3 months.

Halal food industries are growing rapidly in line with the growing number of World’s Muslim populations. The demand of halal food products by the non-Muslim’s countries have also increase as the increasing of the general public understanding of the strickly processed to achive halal status. Halal food is more than just a food product. It is also protect people from poisons, intoxication and hazardous substances exposure. Microbial bioprocess based-food products is one of alternative to create a variety of good quality and nutritious food products. These products can be fermented food, nutraceutical, whole microbes, probiotic and synbiotic. The presence of several microbes in gastric intestinal tract will also maintain mictobiota of human gut. Microbial agent is also important on producing the aroma, taste and color. It is also important on modifiying of food materials. As Muslim, people should follow the halal dietary laws. Halal food means any process to be a food product that is permissible of lawful by Islamic laws. It is defined in the holy Quran and the Sunnah of Prophet Muhammad. In general, the microbial based-food products are categorized into halal, haram and doubtful. To achieve the lawful status, six of main critical points in the use of microbes in food processing need to be considered. Microbial metabolite such as ethanol is one of crucial factor in order to achieve halal status of food products. In order to achieve the global halal market, several strategies must be applied to microbial bioprocess based-food industries.Keywords: microbe, halal, industry, bioprocess, critical point
