Sea rice bran powder is a new type of instant food additive. Currently, its solubility is low, and its flavor is not pleasant. Superheated steam cooking is a promising treatment in cellulose-rich substances, which essentially improves quality. To gain better sea rice bran powder, physicochemical properties of sea rice bran were investigated using 100 °C, 110 °C, 120 °C, and 130 °C superheated steam treatments for 10, 20, 30, and 40 min. After the treatment, these samples were cooled down, dried, and milled to assess sea rice bran powder's product qualities. Profiles of odor, taste, aroma, and aliphatic acids were determined using e-nose, e-tongue, and gas chromatography–mass spectroscopy. Results revealed that superheated steam brought new profiles of odors and tastes for consumers. Superheated steam treatment was found to decrease swelling capacity. Methane (2,2,4,6,6-pentamethyl, heptane) was seen as a significant odor component, whereas umami and bitterness were considered considerable taste components. Superheated steam treatment retained higher content of aliphatic acids: saturated fatty acids 218–204 mg/100 g and unsaturated fatty acids 830–781 mg/100 g. This study discovered that superheated steam is suitable for processing rice bran as food ingredients; 100 °C-120°C and 10-30 min could be suggested for suitable cooking sea rice bran.

Vegetable consumption is associated with increased health benefits, and vegetables are consumed both in cooked form and raw form in salads. All cooking techniques cause changes in a vegetable’s the nutrient content. Consumers are increasingly health-conscious and have less time to prepare meals, and they do not know which cooking times and cooking methods are best suited to preserve the nutrients. This study aimed to determine the best method of cooking vegetables to maintain minerals (potassium and sodium) and carotenoids. The studied vegetables were broccoli (Brassica oleracea, var. Italica), carrots (Daucus carota), and zucchini (Cucurbita moschata). The cooking methods were: boiling, steaming, combined oven, microwave steaming, and microwave cooking. Samples of organic and conventionally grown vegetables were prepared in triplicate. Samples were analyzed to determine the availability of target minerals and carotenoids in the raw food and in each recommended cooking situation according to technical standards. Only the carrot showed a higher concentration in organic cultivation for carotenoids in raw vegetables, with both zucchini and broccoli having higher concentrations when grown by conventional cultivation. The zucchini from organic cultivation presented a reduction of potassium and sodium, almost consistently, in all cooking techniques. Regarding the conventionally cultivated zucchini, potassium remained stable in boiling. Broccoli from organic and conventional cultivation showed similar potassium levels for boiling and traditional steam cooking. Organic carrots showed easier sodium extraction compared with conventional cultivation. Heat treatment, in general, improves the accessibility of carotenoids.

In West Africa, cowpea is processed into several end-products among which the most consumed in Mali is a steamed granulated product known as cowpea couscous or Shô basi, in Bambara. Organoleptic properties ofShô basi are variable, probably as a consequence of the diversity of the practices of production. This study aims at determining these practices, their constraints and the physico-chemical characteristics of Shô basi as sold on Malian markets. A survey using focus group discussions, and involving eighteen (18) Shô basi production cooperatives, each gathering 8 to 32 members, was conducted in South Mali. The information collected was related to cowpea varieties used for production, flow diagrams, constraints of production, and quality criteria of the end-products. Eighteen (18) Shô basi samples were collected from the interviewed groups and used for the determination of the physical and chemical properties of Shô basi. Results showed that most of the processors were married, non or moderately literate and aged between 20 and 59 years women. The main cowpea varieties used for the production are sangaraka and wilibali, both from the species Vigna unguiculata. Both varieties of cowpea are characterized by a white or cream color. Shô basi is produced using a single process with two major technological variants. One involves a wet total dehulling (VDT), whereas the second involves a dry partial dehulling (VDP) of cowpea seeds. Regardless of the technological variant and cowpea variety used, interviewees indicated that a good qualityShô basi must have a light color, a soft mouthfeel texture, a homogeneous granule size and lacking beany flavor. Protein(25,0g/100g) and polyphenol (24,3mg/100g)contents as well as swelling level were similar for Shô basi from both variants. However, Shô basi from technology involving partial dehulling (VDP) was less bright, richer in fiber and minerals, and contained more fine granules thanShô basi involving whole dehulling(VDT). Cowpea dehulling, flour granulation, steam cooking and drying are the mean constraints for quality standardization and large-scale production of Shô basi in Mali.

AbstractThe study was undertaken to investigate the effect of muscle, thermal treatment, and ageing on the beef quality. The longissimus lumborum (LL) and semimembranosus (SM) muscles were taken from Holstein–Friesian young bull carcasses then subjected to steam-cooking and sous-vide after 9 and 14-d wet ageing. It was shown that characteristics of cooked beef were the most significantly affected by thermal treatment method. Using sous-vide provided beef with lower shear force and cooking loss values, darker, and more red colour and more beneficial sensory quality. LL and SM muscles showed a similar quality when subjected to the same thermal treatment method after the same ageing time. It is possible to obtain juicy and tender beef from Holstein–Friesian bulls after 9-d ageing and sous-vide treatment.

This study investigated the influences of steam-cooking on (poly)phenolic compounds and colors in purple yam (Dioscorea alata L.) and purple sweet potato (Ipomoea batatas) tubers cooked at the household level. Steam-cooking did not significantly change the contents of total phenolic compounds, flavonoids, anthocyanins and antioxidant capacity measured by ABTS radical scavenging assay in purple yam (P≥0.05), but lowered the antioxidant capacity measured by Crocin assay (P<0.05). The liquid chromatograph– mass spectrometer–Ion Trap–Time of Flight (LCMS-IT-TOF) indicated the degradation of high MW alatanin B to lower MW alatanins due to the loss of glucose units. Purple sweet potato, however, responded to steam-cooking differently from purple yam (P<0.05). Steam-cooking drastically increased total phenolic compounds, flavonoids, anthocyanins, antioxidant capacities, and retained the vivid reddish-purple color of cooked purple sweet potato (P<0.05). The stability of polyphenolic compounds in starchy tubers against steam-cooking at the household level was, in part, due to the different contents of indigenous phenolic compounds in the raw tubers.

Parabolic trough collector (PTC) is a concentrating collector widely used for steam cooking, water heating, and also steam power generation and desalination work. The performance of PTC is strongly depends on its process parameters and is a MCDM problem. Implementation of integrated method, that is, entropy with graph theory and matrix approach (E-GTMA) for modelling and optimization of PTC parameters to improve higher outlet temperature (To), higher heat gain (h), and higher thermal efficiency (ηth), is discussed in this chapter. Investigation results indicate the effectiveness of this technique for multi-objective optimization and determined optimal setting as Test no.10 for PTC. Additionally, parametric and ANOVA analysis is carried out to determine the significance and adequacy of the developed model. Last, validation of the proposed model and verification results is done via confirmatory tests, and tests results show comparable and acceptable w.r.t. experimental results.
